Pool Tips and Techniques

Most pool technique is geometry. Aiming means sending the cue ball to the ghost ball position; position play means knowing where the cue ball goes after contact, along the 90° tangent line with stun or about 30° off the original line with natural roll near a half-ball hit; banks and kicks are mirror reflections in the rail.

The guides below cover each piece with diagrams that are calculated rather than sketched, and the drills let you check your aim shot by shot.

FAQ

How do you aim in pool?

Picture the ghost ball, the spot where the cue ball must be at contact, one ball width behind the object ball on the line to the pocket, and send the cue ball's center there. Ball-fraction aiming gets to the same spot. See how to aim in pool.

What is the 30° rule?

With natural roll, a cue ball that hits an object ball between about a quarter-ball and a three-quarter-ball hit deflects roughly 30° from its original line. See the 30° rule.
