Ok almost got my stance an everything down. Been trying to perfect my draw stroke. Feel like I'm stroking the ball good an aligned perfect but kept wondering why I draw It back at an angle sometimes to. My cue is not centered with my shot. What movement need to be make to address this? I feel it's my right foot on the shot line position that can fix it? Been trying to get my shoulder behind my head also. It's really weird in the mirror I do it perfectly grip an all but can't reinact it on the table.
Not an instructor, just speaking from my limited experience:
If the cue steers off-line when you draw it back, this could be caused by multiple things, and a video would help diagnose it better
One common reason is that your stance causes some part of your body (typically the side of the chest) to interfere with your right arm's path. If your body is in the way of moving the right arm straight back, the arm will move sideways slightly to continue the motion, causing it to go off-line.
If this is the issue, it can be fixed by changing your stance. A common fix is to step into the shot slightly differently, such that your chest no longer limits the path of the right arm. Try different approaches of where you place your feet, and see if some eliminate this issue.
Another reason for this issue could be vision-related. tomatoshooter gave some good tips about this in an earlier post. Find your vision center and keep your head at the same sideways point while dropping down into the shot, this should ensure that you see the shot properly and your perception of pulling the cue straight back should match the reality.
Also, do you play with your chin and/or chest touching the cue? Not that they are right or wrong, just asking because it might help understand the issue better.
