Bridge and Cueing Arm Positions
Consider a Stroke that requires left side. You need to move your bridge slightly LEFT from the centre ball striking point and you need to move your cueing arm slightly to the RIGHT.
Learning to Adjust your Aim
Now that you know where the cue should point, you need to be able to adjust your aim so that you achieve an accurate cue ball path. The best exercise for this is to place the cue ball on the end spot in the D and practice applying sidespin, making sure that the cue ball travels along the baulk line. It is best to hit the cue ball below centre, at 4.30 or 7.30. Try the shots using both right and left side and importantly, at various strengths, until you can consistently hit the baulk line/side cushion point. Now vary the cue ball distance from the side cushion and repeat. It should not take you too long to get the feel of putting sidespin on the cue ball and getting the cue ball to travel along the baulk line.
As a rough guide, a decent amount of sidespin should enable you to hit baulk line and then the baulk cushion, before the baulk pocket.
