Hi Simon, thanks for your message. Glad you like the videos!!
Addressing your questions I can answer as follows:-
1) It doesn't really matter. Whatever is most comfortable.
2) Personally I prefer the left foot to be in front of the right, as this promotes your weight being forward, but again it doesn't really matter.
3) Make sure that you complete every shot with your grip hand hitting your chest. This will promote an accelerating cue at the point of impact and will improve your timing.In this snooker coaching video we take the three key elements of the set up.
The snooker stance, bridge and grip then put them together to create a solid and reliable snooker cue action.
Hi Tiger, that's great if I've been able to help you. I imagine that you are gripping the cue tightly on power shots before striking the cue ball. Just work on the idea that to create the same power with a light grip, you don't need to deliver the cue with as much pace. This is because the cue will be accelerating as opposed to decelerating with a tight grip. Test it out with an angled blue up and down the spots. No pressure with a pot and you can assess the reaction of the cue ball. Good luck!
Hi Ross, the best way to get your cue as parallel as possible if you are tall is to widen your stance. Bending both knees isn't the best way as this could introduce movement on the shot. Hope that helps! Cheers
