Early on in a tournament when the blinds are low I don't mind staying in and throwing a few bets at a flush draw, especially with a lot of other people in the pot. When the blinds are low even missing doesn't hit your stack very much. If I am reraised while I'm on a draw I usually fold since it isn't worth the risk. Percentages aren't in my favor at that point. Later on in tournaments I try to stay away from all chasing. It just always seems to be an easy way to get yourself out of the money. It is something that a lot of people get carried away with and I was one of them when I first started out. Now I like to think I'm a little more patient and won't put my tournament life on the line with a draw unless I'm short stacked and drawing to the nuts.
