I was watching a pro tournament, can't remember exactly which one, but I think it was the C of C's. It was being played on a table with tight pockets, and I was noticing that there were a lot of missed shots which got me to thinking, when the pros miss a shot, that we all know they should make, what are the main reasons. My 2 guesses were skid and side spin on the cue ball. I would be interested in hearing what you all have to say on this topic. It seemed like the players were jawing a lot of balls in the pocket, at least more than what would be normal.
