Definition: The precise point on an object ball, where you aim for another ball to strike it or for it to sink inside a pocket. Most players line up shots straight for the back of the center of the pocket, but professionals aim shots to cross over the center of the pocket opening (the line of aim takes the ball across the middle of the felt and into empty space).
In other words, a shot coming in from the player’s right cross the middle of the felt semi-circle inside the pocket and if still has speed left, flies into the left side of the pocket backing. Thus, the “pro side of the pocket” is the left side of the back coming from the right side.
