It happens quite often, putting your oponent on a flush or straight draw, when calling your bet on the flop, and then turn shows one of the cards you are worried about. You're first to act, and you start thinking, this pot is real nice, maybe he doesn't have that flush or straight after all. Maybe he had a set or two pair and will fold if I make a bet, even though looking at it afterwards you know it was a silly move not to trust your read and try to bluff. There are many situations like these, you change what you think your opponent has to what you want your opponent to have. This is mainly what I loose pots on at 25NL these days. Any tips on how to stay focused and stop doing silly stuff now and then just because I'd like the pot?
