Today was a hard lesson on what not to do in a long online pool tournament. Playing in a large tournament requires a serious amount of patience and a lot of concentration. I was playing in a tournament for about three hours and managed to lose a major game for no other reason than that I was talking to other people in my house at the same time as trying to shoot some good shots in the game.
That just doesn't work. If you are planning on playing in a serious pool tournament, especially where you are putting up some cash to join it, then you need to make sure you can concentrate on the game you are playing and that you have enough spare time to cover the maximum amount of time that each separate game and the tournament itself are likely to run for.
