How to Make 1-Rail Bank Shot
There are two different approaches when you come with 1-rail bank shot in pool billiards. It depends on the speed you hit the cue ball. The harder you hit the cue ball the more it tightens up the bank, the softer you hit it the wider it makes the bank.
So if you will use the equal difference rule, hit it slow. If you will follow “1/3-More-Than-Twice Bank-Shot” rule hit it fast(average speed).
