The ghost ball method for pool requires you to imagine the cue ball's position at impact along the line of centers-the cue ball pinned on the optimum line through the object ball that drives the target ball to the pocket. Most pool pros do not consciously use this method of aim!
Pros instead aim directly for the contact point on the object ball-even though the geometry of round pool balls dictates that the ghost ball method is the correct line of aim and that contact point aim brings a miss. The pro subconsciously makes any needed adjustment to aim while firing right at the contact point. A contact point hit allows for a typical more full hit on the object ball anyway for enhanced power and control.
The amateur billiards player instead struggles to shoot at the ghost ball. Difficulty is compounded by trying to aim at an imagined point in space, where the pool pro is always targeting at something they can see.
Here's how to do it the pro way and teach yourself the aim compensation also:
1. Locate the target point on the object ball, the furthest possible point on the ball from the center of the pocket drop.
2. Walk back behind the cue ball to find the place where a line from the target point would split the cue ball in half through its absolute center. This spot must be obeyed and will often yield a thicker or thinner cut shot than instinct tells you to take. Players often find themselves in their stance two feet to one side of where they'd aim "naturally".
3. Shoot the ball. Score!
