Just play your game and try to play your own best. Getting caught up in what other players are doing usually results in a poor(er) performance. Take a few extra seconds to breath and focus. Try not to do anything you wouldn't normally do in a round. "Keep it simple, stupid" (K.I.S.S.) is a good motto to live by.
Take the line that gives you the highest percentage. Play smart. What division are you playing? Take your time on each shot! Good Luck! I would have gone to this tourney, but that would make 3 weeks in a row I played in a tourney.
