How does the “bisect-pivot-and-shift” or “midpoint-parallel-shift” aiming system work?
It is described an demonstrated in detail, along with other common aiming systems, in How to Aim Pool Shots (HAPS). A brief summary is below, along with illustrations showing how the contact points, bisect midpoint, and cue pivot angle are related.
– Sighting for a straight in shot from behind the cueball, place tip of cue on table midway between cue ball and object ball.
– Then locate contact point on object ball.
– Keeping tip in same spot on table move to the right or left until the cue is pointing directly at the contact point.
– From there, roll the cue, staying parallel to that line, until the center of the cue is hovering directly above the center of the cueball. That’s your aim line. Pick a spot along this line to aim at in order to pocket the shot.
