In the diagram below, shooting the one-ball into the corner pocket with cue ball A is not too tough for most players. But move the cue ball back to the B position and on a tough 9-foot table, the shot looks a lot more difficult. If all you need to do with the shot is just cinch the ball with center English, it may help when shooting from the B position to IMAGINE that you are actually at the A position. In other words, mentally shorten the shot. It has worked for me, so maybe it will be a help to someone out there.
