ball squat and hop

How do you make the CB squat on the break, and why does the cue ball sometimes hop in the air and/or off the table?

To make the CB "squat" (come to rest near the center of the table) after hitting the rack of balls, it needs to have slight topspin. The larger effective mass of the rack of balls makes the CB bounce back, so slight follow is required to stop that motion. However, due to the force of the power break shot, only slight follow should be used (i.e., the tip should contact the CB only a small amount above center). The following videos illustrate some of the physics involved:

To be able to "squat the rock" accurately and consistently, one must have excellent break shot technique with controlled power.

With a firm break shot, the CB will hop or "pop" into the air after hitting the lead ball. This occurs because the cue is slightly elevated (non-level) to clear the rail. With cue elevation, the CB is driven down into the slate, which causes it to bounce. Also, because the CB is also often hit slightly above center, this drives the CB into the slate even more (due to downward "squirt"), which tends to make it jump and hop even more (for more info, and demonstrations, see the follow-shot hop resource page).

So with a firm break shot, the CB will always be hopping on the way to the rack, and if the CB hits the rack while airborne, it will hop in the air after hitting the lead ball. This is not something one should try to create (e.g., by elevating the cue even more than normal). However, with a well-struck break (i.e., a square hit with significant speed), it is difficult to avoid the hop. The best scenario is if the CB lands exactly at the same time it hits the 1-ball. Then the most energy possible will be delivered to the rack, and the CB hop will be as small as possible. Although, even in this case, the CB will still hop slightly because the CB will still have a downward motion component when it lands at the 1-ball.

One should hit the CB with the cue as level as possible to minimize how much the CB hops on the way to the rack of balls to deliver as much energy as possible to the balls (see cue elevation effects for more info). If the cue is elevated more than it needs to be to clear the rail, the CB would jump and skip more on the way to the rack, possibly causing it to hit the 1-ball even more airborne, which would cause it to hop even higher. But this would not be good because less energy would be delivered to the rack (due to the drag losses during the initial and any subsequent hops).

Now, if you hit the lead ball very squarely with significant CB speed, the CB will most likely hop. However, the hop is really not a good thing ... it is just the result of an accurate and powerful break.

Significant hop can occur only if the CB is airborne when it hits the lead ball. This can occur if the cue is elevated too much and/or if too much speed is used. The CB can also "climb" the lead ball a small amount with topspin from an above-center hit, but this effect is not significant.

If you hit the lead ball squarely (as you should with a good break), the cue ball hop is not a problem (unless it is high enough to hit the light fixture above the table). However, with hop and a non-square hit, the cue ball can easily fly off the table.

To reduce the amount of hop, try keeping the cue as level as possible at impact with the CB. Also, try to reduce how much you are hitting the CB above center, especially if the CB has too much follow action after landing.

You can also reduce the effect of hop by adjusting your break position so the distance to the rack is just right, where the CB lands just as it hits the lead ball of the rack. By moving your CB starting position left or right or forward or backward in the kitchen, you can control where the hop occurs (for a given break speed, cue elevation, and tip contact point).

 

Should I try to make the CB hop in the air when I break?

No; although, with a square hit on the lead ball with good speed, the CB will naturally hop after the hit.

One should actually try to keep the hop as low as possible. For example, one should not add cue elevation (at tip-CB contact) to add more CB hop. And one should not use a break angle and distance that makes the CB hop higher onto the 1 ball causing the CB to hop even higher. Those things will hurt accuracy and consistency, and reduce breaking effectiveness (for a given cue speed).

For those who want to improve their break, the focus should not be on trying to make the CB hop. If one follows all of the recommended break technique and equipment advice and can hit the 1-ball squarely with good speed, the CB will hop (even though the hop is not really helpful).

 

Will the CB have more speed into the rack if it is airborne on the way to the rack?

The CB is in the air only because it is driven down into the table. Most of the initial bounce (that sends the CB airborne) occurs after the CB leaves the tip. The CB loses speed on this initial bounce. Also, if the CB bounces again before reaching the rack, like it usually does for most breakers, the CB will lose more speed on that bounce also. It turns out that because of the bounces, the CB will actually lose more speed (even though it is airborne much of the time) than it would if it were struck with a level cue (if this were possible) where the CB would be sliding the whole way to the rack. In other words, the bouncing and flight of the CB does not result in more CB speed (although, it really can't be avoided ... however, it can be minimized by not elevating the cue more than you need to). For more info see: cue elevation effects.

For those with strong math and physics backgrounds, a detailed analysis of the effects of hopping on the spin and speed on the CB can be found here:

TP B.10 - Draw shot cue elevation effects

The analysis is applied to draw shots with different cue elevations, but the results also apply to a break shots, where the CB is also doing a combination of hopping and sliding.

 

If the cueball is coming in at a slight angle (airborne) and it hits the 1 ball full from this angle, wouldn't that hit transfer the most power?

That's a good point, but it doesn't make much difference at typical CB trajectory angles coming in (which are very shallow). The downside of hitting the 1-ball at a downward angle is that it causes the 1-ball to bounce down into the slate, which will cause a loss of energy and cause the 1-ball to hop some (more lost energy). However, all of this might be a moot point since the CB usually bounces before reaching the 1-ball, in which case the CB might be more likely to have an upward angle if it hits the 1-ball above the equator. With an upward angle, the higher the CB hits the 1 ball, the higher it will bounce, and the less energy it will deliver to the rack of balls. In this case, the best scenario is to the have the CB land as close as possible to the 1-ball, with as few bounces as possible (ideally, just the 1 bounce off the tip).

FYI, the CB will still hop if it hits the 1-ball just as it contacts the table (because it still has an upward or downward speed component, assuming it hops on the way to the 1 ball, as it the case with a fast-speed break).

 


drill

What is a good drill from improving my break shot?

Disc V of the Video Encyclopedia of Pool Practice (VEPP) has a good 9-ball break drill for evaluating and improving your 9-ball break.

from Patrick Johnson:

The idea is to learn to aim the break shot as accurately as any other shot so you can consistently hit the head ball dead square, getting maximum power transfer into the rack and planting the cue ball in the middle of the table. It comes from a piece of advice I heard once and have repeated often to players who are learning to break:

Your break speed should be the maximum speed at which you can consistently pocket a straight-in shot with the cue ball on the head string and the object ball on the foot string, and stop the cue ball dead.

And that pretty much describes the drill:

1. place the cue ball in its normal breaking position

2. place a single object ball on the foot string directly in line with a corner pocket

3. shoot the OB straight into the pocket with a stop shot

4. hit the shot as hard as you think you can, but if you miss the pocket or the cue ball doesn't stop dead, slow the next shot down

5. only speed the shot up again when you've made several successful stop shots in a row

6. gradually build your speed up following the above rule

Here's the setup:

8-ball break

What are possible strategies for breaking in 8-ball?

Disc IV of the Video Encyclopedia of Eight Ball (VEEB) covers this topic if great detail.

First of all, follow the advice in the break technique section.

An alternative to hitting the lead ball on the break is hitting the 2nd-ball or 3rd-ball squarely instead by breaking from the side rail. These breaks can be very effective, assuming they are allowed under the rules by which you play (e.g., APA rules prohibit a 3rd-ball break). These breaks spread the balls well and often result in pocketing a ball. It is also easier to control the CB since less power is required. Here are some examples from Disc IV of the Video Encyclopedia of Eight Ball (VEEB):

 

The main advantage of the 2nd-ball break is that it will often send the far corner ball to the corner pocket (assuming the balls are not too old, and rack well, and sit well on the cloth).  It also has the benefit of causing 8-ball motion, giving you a chance to pocket it on the break, which awards a win under some rules (e.g., the APA league system). The far 2nd-row ball also has a tendency to bank cross side with some equipment and racks.

One disadvantage with a 2nd-ball break is sometimes the balls tend to cluster on the breaking side of the table. Also, not as much CB speed can be used since the hit cannot be as square as with a lead-ball break; therefore, less energy will be transferred from the CB to the racked balls.  Also, because the 2nd-ball break is hit from the side rail (where the cue will be a little more elevated or non-level) and since the CB hits the 2nd ball at a slight angle, not as much CB speed can be used as with a lead-ball break; otherwise, the CB will hop and can bounce off the table (which is a foul).

For more information, see "VEEB - Part VIII: The Break" (BD, June, 2016).

If pattern racking is not prohibited, you might want to use the Corey Deuel approach (see below).

Here are some statistics for effectiveness of pro 8-ball breaks.

 

Should I put balls in certain positions when I am racking for 8-ball?

from CreeDo (in AZB post):

Interesting pattern Corey [Deuel] has come up with for 8b. It not only ensures an even spread for his chosen group, it leaves an ugly cluster for the opponent's group.

He breaks from the corner, hitting the 2nd row ball squarely, maybe 15-17 mph.

In the diagram it's the stripes that spread and the solids that cluster.

8-ball pattern rack

This is what he was left after the break on his own racks. You can see what's happening near the right side of the rack area. Not hard to guess which group he chose in each example.

follow through

Should I use an extended follow through on the break shot?

This is a question of cause and effect. A follow-through strictly has no influence on the cue ball because the cue tip is in contact with the cue ball for only a very short amount of time (approximately 0.001 seconds). The only things that significantly affect the breaking power for a given cue stick are cue stick speed at impact, tip offset (distance away from a center ball hit), and the squareness of the hit on the lead ball. However, if a powerful stroke does not exhibit a big follow-through, it is either not very powerful, or effort is being made to limit the follow-through. If one tries to constrain the follow-through, one will probably not achieve maximum speed at impact. Many authors and instructors recommend trying to "accelerate through the ball" for power shots. This thinking often helps one create good power, and it results in significant follow-through.

Follow-through can also be important in achieving good action on draw shots (although, not always for the reasons people think). For more info, see "Draw Shot Primer - Part V: how to achieve good draw action" (BD, May, 2006). In particular, see item "b" under "other advice" and item "5" under "stroke best practices." I think these points apply equally well to both a power break and a power draw.

from Fran Crimi:

Besides making sure the rack is tight, you MUST exaggerate your follow-through. Even if you think you are following through enough, push through even more. Watch Strickland's follow-through. The cue literally comes out of his bridge hand and is extended all the way down the table. It's difficult to master that letting-go technique with accuracy but with lots of practice, it will pay off in spades.

The other option is to leave the cue in your bridge hand but with an over-extended follow-through, if you lean into the break shot, you will definitely bend the shaft and possibly crack or break it like some other players do.

I prefer the letting-go technique.

 


making the 8-ball

How can I increase my chances of making the 8-ball on the break?

Not all leagues and tournaments award a game victory for making the 8-ball on the break; but if they do, it is wise to try to increase your chances for pocketing the 8-ball. A good technique for this is to place the CB close to the side rail on the head string, and hit the 2nd ball in the rack squarely. The 8-ball will often head toward the opposite side pocket, and the balls will usually disperse well. Clips HSV 7.8-7.11 show how it works. For illustrations and more information, see Section 7.05 in The Illustrated Principles of Pool and Billiards.

 


measuring your own break speed

Is there an easy way to measure your break shot speed without a fancy radar gun?

MyBreakSpeed is a phone app that works very well.

You can also measure your break speed with any computer containing a microphone (see below).

 

from Runnin8:

To find your own break speed:

1) Measure the distance between where your cueball rests on the table for a normal break and the head spot, subtract 2.25" for one ball diameter.

2) Use sound recorder on a PC to record the sound of your break. We used a laptop with it next to the table. Most PCs can record at 44Khz, or 44 thousand times a second, more than accurate enough. Also, forget about having to get it right in the middle. Unless your break speed is near the speed of sound its a nit. Use a sound program like Wave pad to open the file and identify the peak where the cue strikes the cueball and then the peak at rack contact. If you highlight with Wave pad it will tell you to the thousandth of a second.

3) Your break speed in mph is:

(distance-2.25) / 12*60/88 / (measured time)

 


9-ball break

What are possible strategies for breaking in 9-ball?

First of all, follow the advice in the break technique section.

If pattern racking is not prohibited, you might want to take advantage of those approaches (maybe in combination with a soft break per the Corey Deuel example below).

Here are some statistics for effectiveness of pro 9-ball breaks.

 

Should I put balls in certain positions when I am racking for 9-ball?

from CreeDo (in AZB post):

Corey will not be satisfied until he completely breaks 9 ball.

First he figured out how to make a ball on the break every time and get a look at the 1. Then he figured out how to get an easy layout so he can run the whole rack every time. Now he's figured out how to leave himself a wired 9 ball combo after running just 2 or 3 balls:

http://www.youtube.com/watch?v=mZa59OiRJd8

He hasn't quite perfected it, and maybe it only works on the barbox. But in this one match he set it up every time and was able to execute it for 5 out of his 9 wins.

He apparently randomizes a few balls so as to skirt around the pattern racking rule, though it's obvious what he's doing. Sometimes he just has to run to the 3 ball, which is near-wired to the 9. Other times to the 4 or 5. Somehow it's never, say, the 8 ball.

Don't get me wrong, the match actually shows some amazing shots by Corey. It's not like all he does is get early 9's and then runs to the bank.

Dennis seems to be racking differently all the time and breaking much firmer. Almost like he wants a random outcome. I dunno if he's trying to stick to the spirit of the law, or if he just gave up trying to imitate what Corey does. He's pattern racked in the past.

pattern racking strategy

Should I put balls in certain positions when I am racking for 9-ball?

There are certain ball-motion patterns you can take advantage of, whether you are racking for an opponent or racking for yourself. Some of the basics are covered in this video from Disc V of the Video Encyclopedia of Pool Shots:

Joe Tucker's Racking Secrets DVDs also cover this topic in detail. Here's another video (from Scott Brazier) covering the basics:

 

For other examples of pattern racking tricks, see the 8-ball and 9-ball break sections.

 

Isn't "pattern racking" prohibited by the rules?

from the WPA rules:

2.2 Nine Ball Rack
The object balls are racked as tightly as possible in a diamond shape, with the one ball at the apex of the diamond and on the foot spot and the nine ball in the middle of the diamond. The other balls will be placed in the diamond without purposeful or intentional pattern.

Obviously, a strict interpretation and strict enforcement of this rule prohibits "pattern racking," where you place certain balls in certain positions for an advantage. However, the rule isn't usually interpreted so strictly. Often (e.g., in most leagues and tournaments), the last sentence is interpreted: It doesn't matter where the other balls are placed. Also, somebody can easily "pattern rack" without it seeming "intentional" or "purposeful." However, a ref or opponent has the right to protest if certain "patterns" are obviously being used (e.g., always placing the 2-ball in the back of the rack).

Obviously, the best solution is to have a neutral party rack the balls (which is done in the WPBA TV events). With "rack your own" or "opponent racking," "pattern racking" is always likely to occur unless each ball is required to be in an exact position, but this would require a rules change and would result in repetitious run-out patterns (especially with new balls on a "trained" table with consistently good racks).

One way to prevent pattern racking and possible disputes (e.g., in leagues and tournaments) is to use the "No Conflict Rules" for racking and breaking in 8 ball, 9 ball, and 10 ball.

Regardless, even if the balls are truly racked randomly, the balls will still be in a certain pattern in a given rack. And it can sometimes be useful to know where balls in certain positions tend to go.

 


sidespin

Should I use english on a power break shot?

The short answer is:
NO, you should not use sidespin on a break.

Here's the long answer:
If you hit the CB off center, some of the cue's energy will go into spinning the CB and less will go into moving the CB forward. Therefore, for a given stroke speed, the CB will have less forward speed when sidespin is used (i.e., you will have less breaking power). Also, if using sidespin, you need to adjust your aim for squirt; otherwise, you won't get a square hit on the lead ball, which is very important for power. Luckily, with a power break shot, swerve is not a significant factor, so if you have a breaking cue with a natural pivot length well matched to your preferred break bridge length, squirt compensation can be automatic for both intentional sidespin (if you use BHE) and unintentional sidespin. For more info, see Diagram 4 (and the related discussion) in "Squirt - Part IV: BHE, FHE, and pivot-length calibration" (BD, November, 2007).

from Mike Hu (via 9/14/2015 e-mail):

I've been tracking the stats compiled by AtLarge for some time now. Here is the data I have from his AZB posts regarding the 9-ball and 10-ball break. I basically wanted to answer the question: how big of an advantage is the break in these 2 rotation games?

9-ball: 3083/5521 (55.8% win-rate of breaker, 11.6% edge)
10-ball: 1139/2139 (53.2% win-rate of breaker, 6.4% edge)

The data includes his posts from his very first breaking stats post, up to and including his last such post made on 8/25/15. My data for him is only for games played on a 9-foot table (7-ft and 10-ft table stats weren't included). The data does however include tournaments that used a magic rack and those that used a traditional triangle rack. I know this muddles the sample data's "purity" somewhat but I wanted to get a larger sample size in exchange for this "experimental error."

The empirical data confirms what many (most?) people including myself believe, which is the break is a bigger advantage in 9-ball than in 10-ball. My hypothesis for why this edge exists is because 10-ball has 1 more ball in play which makes it harder to run out, harder to pocket a ball(s) on the break, and more ball congestion/traffic to deal with. I think the sample size is sufficiently large enough such that tracking AtLarge's future breaking stats posts will probably not change the data by much. I suspect the 9-ball breaker's edge will stay in the 11.0-11.9% range, and the 10-ball breaker's edge will be in the 6.0-6.9% range.

 


8-ball

Check out "8-Ball Break Stats" (BD, August, 2016) for some interesting statistics for top pro players playing 8-ball on bar-boxes.

 

from AtLarge AZB post:

Here are some stats from the Accu-Stats "Make It Happen" 8-Ball Invitational played November 17-20, 2016 at Sandcastle Billiards in Edison, NJ with pay-per-view streaming by Accu-Stats.

This was a 6-player event, with 15 round-robin matches (races to 10) followed by a playoff match between the 2 players with the best records. The tie-breaker for getting into the finals for players with the same records in matches was the number of games won. The six players were: Darren Appleton, Corey Deuel, John Morra, Rodney Morris, Jayson Shaw, and Shane Van Boening.

The conditions for this event included:
- Diamond 9-foot table with blue Simonis 860 cloth;
- Aramith Tournament balls with the measles cue ball;
- breaker racks using the Accu-Rack racking template;
- alternate breaks from anywhere behind the head string;
- 45-sec. shot clock (90 sec. after the break), with one automatic extension per player per rack;
- take the group you make more of on the break (table open if breaker made same number of each group, or fouled, or broke dry);
- ball in hand behind the line after a foul on the break;
- call shots, except making the 8-ball on the break counts as a win;
- foul on all balls;
- jump cues not allowed;
- lag for opening break.

Overall results for all 16 matches -- The breaker made at least one ball (and did not foul) 73% of the time (182 of 251), won 55% of the games (139 of 251), and broke and ran 41% of the games (102 of 251).

Here's a more detailed breakdown of the 251 games.

Breaker made at least one ball and did not foul:

Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 55% (139 of 251) of all games,
Break-and-run games: The 102 break-and-run games represented 41% of all 251 games, 73% of the 139 games won by the breaker, and 56% of the 182 games in which the break was successful (made a ball and didn't foul).

With alternating breaks, B&R "packages" of the normal type are not possible. But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 102 break-and-run games (including 8-balls on the break) consisted of 4 alternate-break 4-packs (1 each by Appleton, Deuel, Morra, and Shaw), 6 alternate-break 3-packs, 17 alternate-break 2-packs, and 34 singles.

8-balls on the break:
The 102 break-and-run games included 2 8-balls on the break (0.8% of the 251 breaks).

 

from AtLarge AZB post:

Here are some aggregate break statistics from the 2016 US Open 8-Ball Championship, played the past three days at the Rio Las Vegas Resort & Casino. The promoter, CueSports International, provided pay-per-view streaming.

Conditions -- The conditions for this call-shot 8-Ball event included:
- Diamond 7-foot table with 4½" pro-cut corner pockets;
- Simonis 860 Tournament Blue cloth;
- Cyclop TV balls, including the red-spot cue ball;
- jump cues allowed;
- breaker racks using the Magic Rack template;
- alternating breaks from anywhere behind the head string;
- table open after the break;
- ball in hand anywhere on the table after a foul on the break;
- cue-ball fouls only;
- for an 8-ball made on the break, it is breaker's choice to spot the 8-ball and continue shooting or to re-break..

Overall results -- The breaker made at least one ball and did not foul 76% of the time (149 of 197), won 64% of the games (127 of 197), and broke and ran 53% of the games (104 of 197).

Here's a more detailed breakdown of the 197 games.

Breaker made at least one ball and did not foul:

Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 64% (127) of all 197 games,

Break-and-run games: The 104 break-and-run games represented 53% of all 197 games, 82% of the 127 games won by the breaker, and 70% of the 149 games in which the break was successful (made a ball and didn't foul). 

With alternating breaks, B&R "packages" of the normal type are not possible. But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 104 break-and-run games consisted of 1 alternate-break 8-pack (Van Boening), 1 alternate-break 7-pack (Deuel), 1 alternate-break 5-pack (Van Boening), 3 alternate-break 4-packs, 4 alternate break 3-packs, 18 alternate-break 2-packs, and 24 singles.

8-balls on the break: The 8-ball was made on the break 6 times (3.0% of the 197 games). The breaker chose to spot it 5 times and to re-break once.

The conditions for this call-shot 8-Ball event included: Diamond 7-foot table with 4 1/2 " pro-cut corner pockets, Simonis 860 Tournament Blue cloth, Cyclop TV balls (including the cue ball), jump cues allowed, breaker racks using the Magic Rack template with balls from alternating groups around the perimeter, alternating breaks from anywhere behind the head string, cue-ball fouls only, table open after the break, ball in hand anywhere on the table after a foul on the break, making an 8-ball on the break does not count as a win (breaker's choice to spot the 8-ball and continue or to re-break), and an illegal break unless a ball is pocketed or at least 4 object balls reach a cushion (none occurred).

Overall results -- The breaker made at least one ball and did not foul 67% of the time (157 of 233), won 64% of the games (148 of 233), and broke and ran 52% of the games (120 of 233).

Here's a more detailed breakdown of the 233 games.

Breaker made at least one ball and did not foul:

Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 64% (148) of all 233 games, Break-and-run games: The 120 break-and-run games represented 52% of all 233 games, 81% of the 148 games won by the breaker, and 76% of the 157 games in which the break was successful (made a ball and didn't foul). 

With alternating breaks, B&R "packages" of the normal type are not possible. But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 120 break-and-run games consisted of 1 alternate-break 6-pack (by Shaw), 3 alternate-break 5-packs (1 by Robles and 2 by Orcollo), 3 alternate-break 4-packs, 8 alternate-break 3-packs, 18 alternate-break 2-packs, and 27 singles.

8-balls on the break: The 8-ball was made on the break 3 times (1.3% of the 233 breaks), and it was spotted rather than counting as a game win.

Here are some aggregate break statistics from several of the matches of the 2015 World Chinese 8-Ball Masters event, played this week in Qinhuangdao, China. This was a 24-player invitational event, with 12 players from China and 12 from elsewhere.

The conditions for this call-shot event included: 9-foot table with fairly tight pockets and rounded cushion noses, Andy green cloth, Super Aramith Pro balls, measles cue ball, jump cues allowed, referee racks using a template, alternate breaks, foul on all balls, table open after the break, ball in hand behind the line after a foul on the break, making an 8-ball on the break does not count as a win, 130-minute match clock, 45-second time clock (one extension allowed per game) with losing player at halftime having the option to reduce it to 30 seconds, and an illegal break unless at least 3 balls are pocketed or reach the head string.

Overall results -- The breaker made at least one ball and did not foul 70% of the time (72 of 103), won 66% of the games (68 of 103), and broke and ran 49% of the games (50 of 103).

Here's a more detailed breakdown of the 103 games.

Breaker made at least one ball and did not foul:

Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 66% (68) of all 103 games, Break-and-run games: The 50 break-and-run games represented 49% of all 103 games, 74% of the 68 games won by the breaker, and 69% of the 72 games in which the break was successful (made a ball and didn't foul).

With alternating breaks, B&R "packages" of the normal type are not possible. But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 50 break-and-run games consisted of 2 alternate-break 7-packs (by Melling and Yang Fan), 1 alternate-break 5-pack (by Zheng), 4 alternate-break 3-packs, 4 alternate-break 2-packs, and 11 singles. Yang Fan's 7-pack was preceded by a 3-pack at the end of his previous match, so he essentially had an alternate-break 10-pack.

8-balls on the break: The 8-ball was made on the break twice (1.9% of all 103 breaks), but did not count as a win.

Here are some aggregate break statistics from the final 2 days of the 4-day 2014 Accu-Stats "Make It Happen" Invitational 8-Ball event played this week at Sandcastle Billiards in Edison, NJ with pay-per-view streaming by Accu-Stats.

The conditions for this 6-player round-robin 8-Ball event included: Diamond 9-foot table with regular pro-cut pockets, Simonis 860 blue cloth, Aramith Tournament balls, measles cue ball, referee racks using an Accu-Rack SOLO template, alternate breaks, break from anywhere behind the line, call shots, foul on all balls, table open after the break, ball in hand behind the line after a foul on the break, making an 8-ball on the break counts as a win, 90-second time clock after the break, and 45-second time clock on other shots (one extension allowed per game).

Overall results -- The breaker made at least one ball and did not foul 73% of the time (85 of 117), won 61% of the games (71 of 117), and broke and ran 50% of the games (59 of 117).

9-ball

from AtLarge AZB post:

Here are some aggregate break statistics from 24 of the 39 9-Ball matches streamed this past week on a pay-per-view basis by Accu-Stats from the 2016 U.S. Open 9-Ball Championship in Norfolk, VA.

Because the streaming was unstable until Tuesday afternoon, these stats exclude the first 14 streamed matches (Sunday, Monday, and the first two matches Tuesday). They also exclude one match I had to miss on Thursday.

Conditions -- The conditions for this event included:
- Diamond 9-foot Paragon table with pro-cut pockets;
- blue Simonis 860 cloth;
- Accu-Rack racking template;
- Aramith Tournament balls with the measles cue ball;
- winner breaks from the box -- 9" to each side of the long string;
- breaker racks for himself with the 9-ball on the foot spot and the 2-ball at the back of the rack;
- the break is illegal (and non-breaker has an option to shoot) unless at least 3 balls pass the head string or are pocketed;
- foul on all balls;
- jump cues allowed;
- for most matches, a 40-second shot clock with one automatic extension per player per rack; and
- all slop counts.

Overall results -- The breaker made at least one ball (and did not break illegally or foul) 57% of the time (240 of 422), won 54% of the games (227 of 422), and broke and ran 23% of the games (96 of 422). The break was illegal 20% of the time (86 of 422).

Here's a more detailed breakdown of the 422 breaks.

Legal, made at least one ball, and no foul:

Illegal, made at least one ball, and no foul: Fouled (includes 5 breaks that were both fouled and illegal): Legal, dry, and no foul: Illegal, dry, and no foul: Therefore, whereas the breaker won 54% of all games (227 of 422),
Break-and-run games -- The 96 break-and-run games represented 23% of all 422 games, 42% of the 227 games won by the breaker, and 40% of the 240 games in which the break was successful (made a ball, legal, no foul). 

The 96 break-and-run games consisted of 1 4-pack (Van Boening), 3 3-packs (2 by Shaw and 1 by Van Boening), 11 2-packs, and 61 singles.

9-balls on the break -- The 96 break-and-run games included just two 9-balls on the break (0.5% of the 422 breaks). One additional 9-ball was made on the break when the breaker scratched, so it was spotted. With the Accu-Rack, the 9-ball tends to remain close to its original position.

- no jump cues allowed; and
- all slop counts.

The 20 matches (273 games) I watched were as follows. [Note: These stats are for 272 games instead of 273, as the camera was pointed elsewhere during the first part of one game in the Corr/Dudanets match.] These stats do not include the semifinal match, which I was not able to watch.

Overall results -- The breaker made at least one ball (and did not foul) 54% of the time (148 of 272), won 55% of the games (149 of 272), and broke and ran 18% of the games (49 of 272).

Here's a more detailed breakdown of the 272 games.

Breaker made at least one ball and did not foul:

The 49 break-and-run games (including 9's on the break) consisted of five 2-packs and 39 singles. No one in these 20 streamed matches broke and ran more than two games in a row.

9-balls on the break -- The 49 break-and-run games included just 2 9-balls on the break (0.7% of the 272 breaks). One additional 9-ball was made on the break when the breaker scratched, so it was spotted.

Here are some aggregate break statistics from the 2016 WPA World 9-Ball Championship played this week in Doha, Qatar, with free live streaming by Al Kass. [Note that the number of games tracked this year is rather small because of limited streaming.]

Conditions -- The conditions for this event included:
- Wiraka 9-foot tables;
- Simonis 860 Tournament Blue cloth;
- Magic Rack racking template;
- Aramith Tournament balls with the measles cue ball;
- alternate breaks;
- the breaker racked for the first 3 of these matches and the referee racked for the last 3 (with breaker "touch ups" in one of them);
- the 9-ball was racked on the foot spot and the 2-ball at the back of the rack;
- break from anywhere behind the line;
- jump cues allowed;
- WPA rules (all slop counts, foul on all balls) except it is an illegal break unless at least 3 balls are pocketed or pass the head string. 

Only 6 matches (105 games) were tracked, as that is all that were streamed by Al Kass.

Overall results -- The breaker made at least one ball (and did not break illegally or foul) 71% of the time (75 of 105), won 56% of the games (59 of 105), and broke and ran 28% of the games (29 of 105).

Here's a more detailed breakdown of the 105 games.

Breaker broke legally, made at least one ball, and did not foul:

Breaker made at least one ball and did not foul, but broke illegally: Breaker fouled on the break: Breaker broke dry (without fouling, but includes the 2 breaks that were both dry and illegal): Therefore, whereas the breaker won 56% (59) of all 105 games, Break-and-run games -- The 29 break-and-run games represented 28% of all 105 games, 49% of the 59 games won by the breaker, and 39% of the 75 games in which the break was successful (made a ball, legal, no foul).

But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 29 break-and-run games consisted of 2 alternate-break 3-packs (by Shaw and Van Boening), 2 alternate-break 2-packs, and 19 singles.

Here are some break results for the 2015 Mosconi Cup played this week (Dec. 7 - Dec.10) at the Tropicana Las Vegas Casino Hotel Resort. This event is 9-ball racing to 11 matches, with each match being a race to 5 games. The format is one team match (everyone plays one game, then repeat until one side wins 5 games), 7 doubles matches, and up to 13 singles matches (only 10 were played). Europe won 11-7 (the scores favored Europe each of the 4 days -- 3-2, 3-2, 3-2, and 2-1).

The players for the U.S. were Shane Van Boening, Corey Deuel, Mike Dechaine, Justin Bergman, and Skyler Woodward. The players for Europe were Niels Feijen, Darren Appleton, Nick van den Berg, Karl Boyes, and Albin Ouschan.

The conditions for this event included the following: Diamond 9' table with 4¼" corner pockets, Simonis blue cloth, Aramith balls, measles cue ball, jump cues allowed, referee racks in a standard triangle rack with the 9-ball on the foot spot, alternate breaks, break from anywhere behind the head string, no illegal-break rule, 30-sec. shot clock (60 sec. after the break), one 30-sec. extension per side per game, foul on all balls, and all slop counts.

The following stats are for all 4 days of the event combined.

The U.S. broke 71 times, with the following results:
• Made at least one ball (and did not foul) and won the game -- 33 (46%)
• Made at least one ball (and did not foul) and lost the game -- 21 (30%)
• Broke dry or fouled but won the game -- 4 (6%)
• Broke dry or fouled and lost the game -- 13 (18%)

Europe also broke 71 times, with the following results:
• Made at least one ball (and did not foul) and won the game -- 31 (44%)
• Made at least one ball (and did not foul) and lost the game -- 14 (20%)
• Broke dry or fouled but won the game -- 12 (17%)
• Broke dry or fouled and lost the game -- 14 (20%)

For the two teams combined, the breaker made at least one ball (and did not foul) 70% (99 of 142) of the time; the breaking side won 56% (80 of 142) of the games; and the breaking side won 65% (64 of 99) of the games in which the breaker made at least one ball on the break and did not foul.

Break-and-run games, on all breaks:
• USA -- 20 out of 71 (28%)
• Europe -- 17 out of 71 (24%) including one 9-ball on the break
• Total -- 37 out of 142 (26%)

Here are some aggregate break statistics from the 33 9-Ball matches streamed this week by Accu-Stats from the 2015 U.S. Open 9-Ball Championship in Norfolk, VA. 

The conditions for this event included: Diamond 9-foot table with pro-cut pockets, blue Simonis 860 cloth, Accu-Rack racking template, Aramith Tournament balls, measles cue ball, winner breaks, breaker racks for himself with the 9-ball on the foot string and the 2-ball at the back of the rack, break from the box (approx. 9" to each side of the long string), the break is illegal unless at least 3 balls pass the side pockets or are pocketed, foul on all balls, jump cues are allowed, and all slop counts (except I'm not sure whether a 9-ball pocketed in a foot-rail pocket counted, as that did not happen on stream). A 40-sec. shot clock (with one extension per rack) was used on the full-production matches.

Overall results -- The breaker made at least one ball (and did not break illegally or foul) 62% of the time (353 of 572), won 53% of the games (302 of 572), and broke and ran 23% of the games (131 of 572).

Here's a more detailed breakdown of the 572 games.

Breaker broke legally, made at least one ball, and did not foul:

Breaker made at least one ball and did not foul, but broke illegally: Breaker fouled on the break (includes 1 break that was both fouled and illegal): Breaker broke dry (without fouling, but includes the 11 breaks that were both dry and illegal): Therefore, whereas the breaker won 53% of all games (302 of 572), Break-and-run games: The 131 break-and-run games represented 23% of all 572 games, 43% of the 302 games won by the breaker, and 37% of the 353 games in which the break was successful (made a ball, legal, no foul). The 131 break-and-run games consisted of 2 4-packs (Y-H Cheng and K-L Hsu), 4 3-packs, 16 2-packs, and 79 singles.

9-balls on the break: The 131 break-and-run games included just two 9-balls on the break (0.3% of the 572 breaks). With the Accu-Rack, the 9-ball tends to remain close to its original position.

Here are some aggregate break statistics from the 2015 World Cup of Pool played this week at York Hall in London, England, with free live streaming on ESPN3 (and others).

The conditions for this event included: Diamond 9-foot table, Simonis 860 blue cloth, wooden triangle rack, Super Aramith Pro balls with the measles cue ball, referee racks with the 9-ball on the foot spot, winner breaks from anywhere behind the head string, jump cues allowed, 30-second shot clock (60 sec. after the break) with one extension per team per game, and WPA rules (all slop counts). 

Overall results -- The breaker made at least one ball (and did not foul) 66% of the time (77 of 117), won 52% of the games (61 of 117), and broke and ran 16% of the games (19 of 117).

Here are some aggregate break statistics from the 2015 WPA World 9-Ball Championship played this week in Doha, Qatar, with free live streaming by Kozoom.

The conditions for this event included: Wiraka 9-foot tables, Simonis 860 Tournament Blue cloth, Magic Rack, Super Aramith Pro TV balls with the measles cue ball, alternate breaks, breaker racks with the 1-ball on the foot spot and the 2-ball at the back of the rack, break from anywhere behind the line, jump cues allowed, WPA rules (all slop counts, foul on all balls) except it is an illegal break unless at least 3 balls are pocketed or pass the head string. 

Overall results -- The breaker made at least one ball (and did not break illegally or foul) 88% of the time (300 of 340), won 62% of the games (210 of 340), and broke and ran 37% of the games (126 of 340).

Here's a more detailed breakdown of the 340 games.

Breaker broke legally, made at least one ball, and did not foul:

Breaker made at least one ball and did not foul, but broke illegally: Breaker fouled on the break: Breaker broke dry (without fouling, but includes the 2 breaks that were both dry and illegal): Therefore, whereas the breaker won 62% (210) of all 340 games, Break-and-run games: The 126 break-and-run games represented 37% of all 340 games, 60% of the 210 games won by the breaker, and 42% of the 300 games in which the break was successful (made a ball, legal, no foul). 

With alternating breaks, B&R "packages" of the normal type are not possible. But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 126 break-and-run games (including 9's on the break) consisted of 3 alternate-break 4-packs, 4 alternate-break 3-packs, 20 alternate-break 2-packs, and 62 singles.

9-balls on the break: The 126 break-and-run games included just three 9-balls on the break (0.9% of the 340 breaks). With the Magic Rack, the 9-ball tends to remain close to its original position.

Observation: As was true in this event last year, the effects of using the Magic Rack were quite striking. On all 15 scratches on the break, at least one object ball was pocketed. So, in total, the breaker failed to make a ball on the break in only 11 of the 340 breaks (3.2%), an enormous difference from when the Magic Rack is not used. The high stay-at-table percentage after the break means many more opportunities to run out, so the B&R percentage is also high.

Here are some aggregate break statistics from the 22 9-Ball matches streamed free by AZBtv from the 2015 Turning Stone Classic XXIV in Verona, New York. 

The conditions for this event included: Diamond 9-foot table with pro-cut pockets, Tournament Blue Simonis 860 cloth, Aramith Tournament TV balls with the measles cue ball, Diamond wooden rack, winner breaks from the box (2 diamonds wide), loser racks, cue-ball fouls only except during the act of shooting, no jump cues allowed, and all slop counts.

Overall results -- The breaker made at least one ball (and did not foul) 59% of the time (188 of 317), won 57% of the games (182 of 317), and broke and ran 23% of the games (73 of 317).

Here's a more detailed breakdown of the 317 games.

Breaker made at least one ball and did not foul:

Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 57% (182 of 317) of all games,
Break-and-run games: The 73 break-and-run games represented 23% of all 317 games, 40% of the 182 games won by the breaker, and 39% of the 188 games in which the break was successful (made a ball and didn't foul). The 73 break-and-run games (including 9's on the break) consisted of two 3-packs (one by Van Boening and one by Shaw), thirteen 2-packs, and 41 singles. Van Boening's 3-pack was in the final 3 games of one match, and he broke and ran the first game of his next match, so he had a "carryover" 4-pack.

9-balls on the break:
The 73 break-and-run games included 7 9-balls on the break (2.2% of the 317 breaks). One additional 9-ball was made on the break when the breaker scratched, so it was spotted.

The conditions for this event included the following: Diamond 9' table, Simonis blue cloth, Super Aramith Pro balls, measles cue ball, jump cues allowed, referee racks in a standard triangle rack with the 9-ball on the foot spot, alternate breaks, break from anywhere behind the head string, no illegal-break rule, 30-sec. shot clock (60 sec. after the break), one 30-sec. extension per side per game, foul on all balls, and all slop counts.

Here are the final results:

The U.S. broke 57 times, with the following results:
- Made at least one ball (and did not foul) and won the game -- 29 (51%)
- Made at least one ball (and did not foul) and lost the game -- 17 (30%)
- Broke dry or fouled but won the game -- 1 (2%)
- Broke dry or fouled and lost the game -- 10 (18%)

Europe broke 62 times, with the following results:
- Made at least one ball (and did not foul) and won the game -- 33 (53%)
- Made at least one ball (and did not foul) and lost the game -- 12 (19%)
- Broke dry or fouled but won the game -- 10 (16%)
- Broke dry or fouled and lost the game -- 7 (11%)

For the two teams combined, the breaker made at least one ball (and did not foul) 76% (91 of 119) of the time, won 61% (73 of 119) of the games, and won 68% (62 of 91) of the games in which he made at least one ball on the break and did not foul.

Break-and-run games:
- U.S. -- 17 out of 57 (30%).
- Europe -- 24 out of 62 (39%) including one 9-ball on the break.
- Total -- 41 out of 119 (34%).

Here are some aggregate break statistics from the 33 9-Ball matches streamed by Accu-Stats from the 2014 U.S. Open 9-Ball Championship in Chesapeake, VA.

The conditions for this event included: Diamond 9-foot table with pro-cut pockets, blue Simonis 860 cloth, Diamond wooden rack, Aramith Tournament balls, measles cue ball, winner breaks, breaker racks for himself with the 9-ball on the foot string (spot moved up approx. 4") and the 2-ball at the back of the rack, break from the box (approx. 9" to each side of the long string), a 9-ball made on the break spots up if it went in either of the two foot-rail pockets, the break is illegal unless at least 3 balls pass the side pockets or are pocketed, foul on all balls, jump cues are allowed, and all slop counts (except as stated for 9-balls on the break). A 40-sec. shot clock (with one extension per rack) was used on the full-production matches.

Overall results -- The breaker made at least one ball (and did not foul) 53% of the time (315 of 592), won 50% of the games (298 of 592), and broke and ran 20% of the games (118 of 592).

Here's a little more detailed breakdown of the 592 games.

Breaker made at least one ball and did not foul:

Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 50% (298) of all 592 games,
9-balls on the break:
The 118 break-and-run games included just 6 9-balls on the break (1.0% of the 592 breaks). In addition, 3 9-balls (0.5% of the breaks) were made that went in one of the two bottom pockets and had to be spotted rather than counting as wins.

Illegal breaks:
An illegal break (failure to have at least 3 balls pass the side pockets or be pocketed) was called on only 4 of the 592 breaks. Strangely enough, 2 of those 4 were in the final match. One of the 2 in the final match was in the final game; Orcollo surrendered the table on a wet break and Van Boening ran out for the match win. But the total number of illegal breaks was so small that I just ignored those violations for purposes of these stats rather than create any additional categories.

Here are some break statistics from the 2014 WPA World 9-Ball Championship played this week in Doha, Qatar, with free live streaming by Kozoom.

The conditions for this event included: Wiraka 9-foot tables, Simonis 860 electric blue cloth, Magic Rack, Super Aramith Pro TV balls with the measles cue ball, alternate breaks, referee racks with the 2-ball in back, break from anywhere behind the line, jump cues allowed, WPA rules (all slop counts) with the exception that it is an illegal break unless at least 3 balls are pocketed or pass the head string. Apparently no shot clock was used, despite earlier indications that it would be.

The 15 matches (255 games tracked) that I watched were as follows.

Overall results -- The breaker made at least one ball (and did not break illegally or foul) 89% of the time (226 of 255), won 61% of the games (155 of 255), and broke and ran 35% of the games (89 of 255).

Here's a more detailed breakdown of the 255 games.

Breaker broke legally, made at least one ball, and did not foul:

Breaker made at least one ball and did not foul, but broke illegally: Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 61% (155) of all 255 games, Break-and-run games: With alternating breaks, B&R "packages" of the normal type are not possible. But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 89 break-and-run games (35% of all the games) consisted of 4 alternate-break 3-packs, 8 alternate-break 2-packs, and 61 singles.

9-balls on the break: The 89 break-and-run games included just two 9-balls on the break (0.8% of the 255 breaks). With the Magic Rack, the 9-ball tends to remain close to its original position.

Observation: The effects of using the Magic Rack are quite striking. On all 16 scratches on the break, at least one object ball was pocketed. So, in total, the breaker failed to make a ball on the break in only 6 of the 255 breaks (2.4%), an enormous difference from when the Magic Rack is not used. The high stay-at-table percentage after the break means many more opportunities to run out, so the B&R percentage is also high.

10-ball

from AtLarge AZB post:

Here are some aggregate break statistics from the 2016 US Open 10-Ball Championship, played the past three days at the Rio Las Vegas Resort & Casino. The promoter, CueSports International, provided pay-per-view streaming.

Conditions -- The conditions for this call-shot 10-Ball event included:
- Diamond 7-foot table with 4½" pro-cut corner pockets;
- Simonis 860 Tournament Blue cloth;
- Cyclop TV balls, including the red-spot cue ball;
- jump cues allowed;
- breaker racks using the Magic Rack template with the 2- and 3-balls on the back corners;
- alternating breaks from anywhere behind the head string;
- cue-ball fouls only;
- opponent has choice to shoot or return the shot if a called ball goes in the wrong pocket or a ball is made on a safety; and
- spot any 10-ball made on the break.

Overall results -- The breaker made at least one ball and did not foul 79% of the time (183 of 232), won 59% of the games (138 of 232), and broke and ran 38% of the games (89 of 232).

Here's a more detailed breakdown of the 232 games.

Breaker made at least one ball and did not foul:

Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 59% (138) of all 232 games, Break-and-run games: The 89 break-and-run games represented 38% of all 232 games, 64% of the 138 games won by the breaker, and 49% of the 183 games in which the break was successful (made a ball and didn't foul). 

With alternating breaks, B&R "packages" of the normal type are not possible. But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 89 break-and-run games consisted of 1 alternate-break 6-pack (by Morris in the hot-seat match against Van Boening), 6 alternate-break 3-packs, 10 alternate-break 2-packs, and 45 singles.

10-balls on the break: The 10-ball was made on the break only once (0.4% of the 232 breaks), and it was spotted rather than counting as a game win. With the Magic Rack, the 10-ball tends to remain close to its original position.

Here are some aggregate break statistics from the 2016 Diamond Open 10-Ball Professional Players Championship played this week at the Super Billiards Expo in Oaks, PA. Pay-per-view streaming was provided by AZBtv. This was a 64-player modified double-elimination event won by John Morra.

Conditions -- The conditions for this event included:
9-foot Diamond Smart Table with 4½" corner pockets and blue Simonis cloth;
- Aramith Tournament balls, including the cue ball;
- wooden triangle rack;
- rack your own (2- and 3-balls need not be in the back);
- alternating breaks from anywhere behind the head string;
- jump cues allowed; 
- cue-ball fouls only; 
- only 1 timeout per match (not per player), to be taken only after at least 10 games have been played; and
- all slop counts, except spot any 10-ball made on the break.

The stats are for the following 16 streamed matches. These matches totaled 260 games, but I missed or had streaming problems during 7 of the games, so the stats are for 253 games.

Overall results -- The breaker made at least one ball (and did not foul) 51% of the time (128 of 253), won 49% of the games (125 of 253), and broke and ran 18%of the games (45 of 253).

Here's a more detailed breakdown of the 253 games.

Breaker made at least one ball and did not foul:

Breaker fouled on the break: Breaker broke dry (without fouling): Therefore, whereas the breaker won 49% (125 of 253) of all games,

Break-and-run games: The 45 break-and-run games represented 18% of all 253 games, 36% of the 125 games won by the breaker, and 35% of the 128 games in which the break was successful (made a ball and didn't foul).

With alternating breaks, B&R "packages" of the normal type are not possible. But we can still look at the breaks of a given player and see how many he ran on his own successive breaks, and we can call these "alternate-break packages." The 45 break-and-run games consisted of 1 alternating-break 5-pack (by Van Boening), 1 alternating-break 3-pack (by Pagulayan), 3 alternating-break 2-packs, and 31 singles.

10-balls on the break: The 10-ball was made on the break 7 times (2.8% of the 253 breaks), but it did not count as a game win and was spotted.

technique and equipment advice

What is some important basic advice about the break shot?

Here's a video demonstration of recommended "best practices" for break technique, from Disc III of the Billiard University (BU) Instructional DVD series:

For more info, see: "How to Break Like a Pro" (BD, August, 2016), "Billiard University (BU) - Part X: The Break Shot" (BD, May, 2014), ball hop and squat, and the following helpful video from Colin Colenso (see the quotes below also): NV A.20 - Colin Colenso's power break instructional video.

Here's a technique analysis of Shane Van Boening's 9-ball break:

 

For more information, see: "How to Break Like a Pro" (feature article, BD, September, 2016).

Here's a great example of an effective 10-ball break, also from Shane Van Boening:

Here's a slow-motion video of Shane Van Boening's 10-ball break (and here's another). Shane's break is very consistent and effective, creating power seemingly effortlessly. Here's one of Francisco Bustamante.

The most important thing to remember is: an accurate (square) hit on the lead ball is the most important factor for a good break. Use only as much power as you can control. In general, you want to use a longer bridge length and stroke for shots with more power (e.g., the break). Make sure your bridge hand is stable and still during the forward stroke (or at least until CB impact), and follow through as straight as possible. Also keep your grip hand as relaxed as possible, and keep the cue as level as possible. In general, try to follow stroke "best practices," even on the break shot. And it is also very important to know how to get a tight rack.

It is advisable to use a break cue with a natural pivot length well matched to your break bridge length. This will allow squirt to exactly cancel stroking errors that cause the tip to hit left or right of center ball, assuming your initial center-ball aim is accurate. For more information, see the natural pivot length resource page.

It also helps to use a hard (e.g., phenolic) tip. This results in more CB speed for the same cue speed (see cue tip efficiency for more info).

Many people raise their body during the break because they also straighten their arm and/or drop their elbow. These two motions counteract each other, keeping the cue close to level at impact. Also, straightening the arm can allow many people to generate more cue speed by getting more of the shoulder muscles involved. However, accuracy (a center-ball hit on the CB and a square hit on the rack lead ball) are much more important than a little extra power, so body motion should be kept to a minimum if accuracy suffers as a result. For more info on the effects of elbow drop, see the stroke elbow drop resource page. An extreme example of what can be done with shoulder motion to create more power is in the following video of Xiaoting Pan:

from Colin Colenso:

There are a few concrete physical / biomechanical contributors which can add velocity to the cue and hence make for bigger breaks. I'll discuss the main ones in order of what I consider to be the most important.

1. Long Lever: By standing higher during the shot, the effective length of the lever is increased. So just as long golf clubs have higher head speeds, a longer arm allows higher cue speed. One doesn't necessarily have to lunge upward to achieve this, but starting low and then raising the body may seem more conducive to better aiming.

2. Centripetal Force: The lunge upward of the shooting shoulder also produces a force at right angles to the direction of the cue movement. This centripetal force accelerates the cue, in the same way that hammer throwers accelerate the hammer by pulling at 90 degrees against it as it rotates.

3. Forward Lunge: Forward lunging creates additional cue speed also, just as shot putters can throw further with a glide throw rather than just a standing throw. One may be able to lunge at 2-3mph and this component can be added to the overall cue speed.

The trick is working out the technique of these various factors such that they can all contribute with minimal loss of control.

I do believe a good wrist flick can contribute as much speed as the 3 effects above combined and it becomes hard to execute that as well while lunging, so a well timed stroke with minimum movement and with a reasonable length of lever can produce some very powerful controlled breaks.

That said, if one wants to break a world record, they might need to add a lunge to their technique.

 

from Colin Colenso:

some people can add 2-3 mph to their break by shortening their back hand position. There are two possible advantages of doing this.

1. With a longer arm (lever) on breaking due to being more upright, moving the hand towards the bridge brings it more into a right angled position which makes it more effective (and effectively longer), than having a longer back arm which is at a shallower angle to the cue. Imagine if the arm were stretched to the back of a 7 foot cue and you can visualize that the force is being applied at an inefficient angle.

2. Maybe the main reason is that shortening the back hand means that the pectoral (chest) muscle and front deltoid (shoulder) muscles (which are the source of most of the power) are put in a neutral / mid position in regard to extension / contraction. This is where muscles are at their strongest and can accelerate with more force, allowing a powerful punch with a limited back swing.

To get the feel for how this works, try a Bruce Lee 1" punch, first with arm almost fully extended, next with fist almost contracted back near your shoulder and one midway. The midway position is much stronger at applying a rapid burst of force. Different muscles involved, but you'll get the idea of what I mean by mid/extension power.


from mosconiac (in AZB post):

There is a limit that most players reach (expressed in mph) due to lack of timing, leverage, & weight transfer. Older men & most women seem to plateau around 18-20mph. Most males plateau around 22-24mph. Yes, there are freaks of nature that inherently hit 30+mph, but those guys aren’t reading this thread, I suppose.

To get to the next level, players need to add a seemingly unnatural movement (really a series of movements coalesced into one) to the break routine. Most that try it end up striking the CB erratically and give up. Those that can get past that acclimation stage (through practice) will be rewarded.

All great breakers share these tendencies:

  1. Low initial body position (aids upward body movement) with compact stance (aids weight transfer) & forward hand position (aids final alignment/delivery of cue)
  2. Abruptly raise cue at end of backswing (stores energy in arm & shoulder) and cock elbow behind body (stores more energy)
  3. Upper body releases (forward & up) with hips driving forward (sometimes with a turning motion like a golf swing)
  4. Elbow begins driving down & thru (cue returning to pre-shot alignment)…arm release lags behind body release
  5. At impact, upper body & hips are fully released (driven by rear foot), elbow is fully dropped (& driving forward), and weight shift causes rear leg to rise up for counter-balance.

from Patrick Johnson:

As with other major breakers, it appears to me that the crucial feature in Larry's powerful break is the involvement of his upper arm. The elbow drop and standing up are both integral to getting a full-arm swing.

Much is made of the "lunge" of these power breakers, and I'm sure that contributes significantly, but I believe the straightening of the arm for the full-arm swing is the most important element in getting more power - and, of course, the main difficulty in hitting the CB accurately.

 

from sfleinen:

Here's of one of the most powerful (and controlled) breakers in the world -- the mighty Russian, Evgeny Stalev:

http://youtube.com/watch?v=PkCG3q2PDa4#t=560

He's all of 150lbs soaking wet, yet clocks in 35+ mph breaks (he was averaging that in the U.S. Open the video above was taken from). Evgeny (pronounced "yev genny" with a hard "g" sound in the second syllable, for those Russian-pronunciation-challenged like us Americans) uses shoulder, elbow, and his pectoral (chest) muscle to achieve this power. You'll notice he doesn't use any "lunging" motion at all, but rather a very smooth "forward drift" motion in his stance. ... And he does all this with his playing cue!

In my opinion, Evgeny's got one of the smoothest, most powerful, and, for what's going on in his arm, accurate breaks around. Ask yourself, have you ever heard that kind of sound from a break? It's one thing to hear it in this video; quite another to hear it in person (the video lacks some of the auditory fireworks that seeing/hearing this live gives).

 

from KMRUNOUT:

Having studied the break for some time now, I've watched most of the great breakers. You might notice that Evgeny Stalev is remarkably similar to Shane VanBoening. They both have that "forward drift" thing going on. However, both also gently stand up as they *back stroke*. Another similarity is that they both keep their bridge hand pretty well anchored to the table. The result is a setup that allows for a very gentle relaxed building of power. This, I think, is the reason why they are able to consistently hit the rack so square and control the cueball.

As for the body movement, here are my thoughts: can someone hit the rack in the high 20 mph range using just the arm, without moving the body? Not too likely. However, even if they could, it would seem to have to be a very aggressive movement. It would certainly be a very *short* lever and would require explosive power and speed. Remember that this power does not occur in a vacuum-there will be an equal and opposite force acting somewhere. This will require effort to keep the shoulder and the elbow from moving, and I think this can cost accuracy. By rotating the body slightly (the hips then the shoulders, like in a golf or baseball swing), you can provide a (moving) platform from which to execute this arm swing. You will notice a lot of breakers kick their leg back. This really has little to do with generating power. It is a *counterbalance*. The leg is rotating around the body in the opposite direction as the shoulders. This makes it easier to keep the spine in the same location as the shoulders (and leg) rotate around it. This can be practiced. The trade off is that initially you will have less cue ball control on the break. Soon, though, the benefit will be that it is *easier* (requires less effort) to swing the cue fast. So if you wish to break at, say, 25 mph...you *might* be able to achieve this with an arm-only swing (highly doubtful), but I would really like to see that motion result in quality cue ball control, because I doubt I would see that. If your goal is to break at 18 mph, then sure, use only your arm and you can have great cue ball control. 18 mph, though, is not always the best speed for a given table, especially in 8-ball.

I guess in summary what I am saying is that while you may get decent cue ball control at lower speeds with an arm only motion, I believe it is easier to develop good control at higher speeds using a more effortless technique, more like Stalev and VanBoening.

 

from Cornerman:

I notice that players that are stronger in the arm can break big with a short bridge. Others get great control with a super long bridge. Anyone who discourages the long bridge needs to step back and really really really make sure they understand the mechanic and why some players can indeed get better control with a longer bridge.

The longer bridge allows you to get to a higher speed while maintaining a lower acceleration. That is, you might be under more control with a longer bridge in getting the final desired stick speed. The shorter bridge, you'll need to have a higher acceleration for the same final stick speed. And that will need more arm strength to keep under control.

At the [2006] Derby City, I watched intensely some of the hardest breakers. The timing and coordination is something that if it's not natural, it would take some work. Again, add a few things at a time, and it could work wonders.

Elbow
There are two distinct power breaks that I've seen: Elbow Drop and Elbow Rise.
Elbow Drop Breakers: most hard breakers. For pros, this might include Bustamante, Sigel, Strickland, etc.
Elbow Rise Breakers: Archer, Breedlove, Lil John, Sparky Ferrule, Sarah Rousey.
In either case, the elbow drops, but since the Risers rise, the tip dips down on the back stroke, and shoots up on the final stroke. So, Elbow Risers aim at the center or a hair high on their setup.
For Droppers, most will aim low. Really low. Some aim right to the base of the ball or lower. Since they do this, and they get good contact, I assume the elbow is dropping before the tip contacts the ball.
Tip
Most of the hard breakers seem to be able to take that tip all the way to the bridge loop, often actually passing through it. This ensures the longest travel to get up to higher speed, without having to bully the stroke.
Backswing/Pause
I notice that most hard breakers take the final backswing relatively slowly, like they're drawing a bow. Players like Sarah will actually pull it back to the loop and almost freeze with her raised elbow high in the air. Archer also freezes with the elbow higher, but not nearly as high as Sarah's nor for as long a time.
Hips
There is definitely something to be said about rocking your hips back slowly on your final backswing and then leading with the hips on the final stroke before you start the forward swing. Pagulayan is a good example of this. On video, this might cause you to think he's pausing his stroke because the stick stop at the full back position while his hips start their move forward. This is probably the most difficult timing transition. The hip lead is part of the aforementioned freeze.
Follow Through
A lot of today's breakers follow through by letting go of the bridge hand, and bring the cue forward past the center of the table (if they can reach). I don't know if this really helps, but the act of following through helps to not check up your stroke. I still follow through to the table like Sigel, but not so pronounced.
So, even if you do any of the above in small controlled doses, rather than the wild lunge like Breedlove or Sarah, it will add power.
Whatever you do, if you find the cueball going forward after hitting the rack, either lowering your tip at address, or raising your elbow during the backswing can prove helpful.


from Colin Colenso:

Firstly, the long bridge will help but so can these, but they may be tricky to control for accuracy until you practice it a bit.
Firstly, transfer some of the force to the more powerful muscles, the pectorals. You can do this in three ways.
Turn your body more side on to the shot.
Stand up a little higher.
Move your body away from the cue an extra inch.
You'll start to get a slight discus version of a swing which can produce much more power than standard cueing which relies a lot on the biceps.
Also, relax you wrist and focus on letting it flex back in the early part of your forward delivery.
When I put these together and time the wrist, my biggest problem is keeping the CB on the table. The CB can land by the center pocket and bounce off the table from being only a fraction off center on the break.
But give it a try, coz at even 80% effort, if you can time these things using more of the pecs and wrist, you'll get plenty of power and can still control the accuracy.

 

from Jal:

You want the cueball to have some topspin when it meets the rack. This will act like a brake and stop it from rebounding back too far.

It doesn't necessarily mean hitting above center. The cueball will tend to pick up some topspin after it leaves your tip, even if it sails all the way to the rack. It gets it from the first bounce off the bed just after tip/ball impact, and of course, any subsequent bounces. (In fact, to my understanding, if it is airborne all the way, it should pick up more topspin from the one bounce than if it slid along the surface the entire way.)

Exactly where to strike to get the right amount of topspin depends on ball speed, cue elevation and cloth/ball conditions. But, it's going to be near centerball.

The adjustment, in theory, is very simple. If the cueball is following too far forward, hit lower; if it's rebounding back too far, hit higher. If it's badly inconsistent, shorten your bridge length and/or slow down some until you get better control.

 


10-ball break

What is a good approach for the 10-ball break?

Below is a good summary of what seems to be a good approach (e.g., used often by Corey Deuel and others).

Here's a great example of an effective 10-ball break, from Shane Van Boening:

Here are some statistics for effectiveness of pro 10-ball breaks. For technique advice, see the break technique and equipment advice resource page.

 

From spoons (concerning Corey's break at Valley Forge in 2009):

The break

10-ball break - part 1

He broke from slightly off center and seemed to be trying to hit the 1 ball as squarely as possible, with what appeared to be a hint of draw on the cue ball. The draw should help him make the 2 and 3 in the sides. It also brings the cue ball to the head rail out of the traffic, and back to the middle of the table for position on the 1. It was not a "soft" break like he uses in 9-ball. He was hitting them hard enough to send the 6 and 7 around the table 3 rails, but not much harder than that.

What he was playing

10-ball break - part 2

He seemed to be clearly playing the 2 and 3 balls in their respective side pockets. Those are the two he made most often. But, as a secondary option, he seemed to be playing the 6 and 7 in their respective corners. By breaking from a few inches off of center, he should send those two balls around the table at slightly different speeds and give them a chance to miss kissing each other near the head rail.

The rest of the rack

10-ball break - part 3

Racking the 4 and 5 where he did leaves those two balls together and uptable which would be the most natural place for the 2 and 3 balls to head if he doesn't make them in the side, and racking the 8 and 9 where he did leaves a 3 ball cluster near the foot spot for him to finish the out. If the 6 and 7 don't fall, they're likely to end up down at the foot of the table which gives him a couple of balls to work off of to get position on the 8,9,10 cluster.

He rarely made more than a ball or two on the break, but if he ever made all four of the ones he was playing, it would be a throw in rack. Regardless, he left himself similar, and often simple racks to work with.

 


theoretical simulation

If all of the balls were perfect and racked perfectly, how would the balls move after a perfect break?

Here is an interesting analysis and simulation showing the results of a perfect break with perfect balls by Jim Belk of Bard College. Here is one of the results, assuming everything is perfect, with elastic (Hertzian) compression of the balls:

pool break simulation

 


tight rack

How do you get a tight rack for the most effective break?

If a racking template is allowed and is available, they can provide the best rack possible. If not, try the following things:

If the balls are old and worn, it may be impossible to get a perfectly tight rack (with all balls frozen). For example, if the center ball (the 8, 9 or 10) is smaller than the others or not perfectly round, it will not be possible to freeze it with all of the surrounding balls.
