There are three basic ways to sink a single-bank. All 3 relate to the english you apply to the cue-ball. Being comfortable taking all three will prepare you for learning more advanced single-bank english shots which will be discussed later.
The first single-bank shot you want to start making consistently is without applying any english, draw or follow. It is important to emphasize that you shouldn’t use FOLLOW when practicing this shot. If you don’t hit the cue-ball hard enough, follow will be applied. The cue-ball will pick up a natural foward roll and you won’t get the correct understanding of what is actually happening once the cue-ball makes contact with the object ball.
Hitting the cue-ball center will give you the angle into the rail, angle out of the rail effect.
