Thank you for the answers. I was debating if I should keep my back leg straight, and if I should use my square snooker stnace or sideway stance. I am suprised to see so many people keep a straight back leg.
1. Are you square or sideway?
slightly sideways. I used to keep my body straight, but I am now sideway
2. Do you bend your back leg or keep it straight?
I used to keep the legs straight, then I bent it, then I kept it straight, and now I am bending it again. I lock my hip to keep my body from moving.
3. Does your chin touch the cue?
Yes, always. From snooker, old habit.
4. Do you open your hand on your backswing?
I used to never move my wrist, then I tried to keep it loose but never intentionally open it. I am not sure if I open it or not now.
5. Does your cue touches your chest?
I used to all the time, it was good for accurate shots, but I lacked a bit of power, and sometimes I felt "choked" so I let it stay very close to my chest now.
