People tend to conveniently forget the many times that they have sucked out on others. Just a few weeks ago I sucked out massively at a crucial stage of a tournament.
I flopped a set of 8s, the money went in and my opponent turned over a set of 9s. The river was an 8.
That said, my computer almost went through the window yesterday thanks to a hand that propably cost me a few grand deep in a tourney. UTG raises, I call with 9-9, flop comes 7-8-5. He checks, I bet, he calls. Turn 3. We both check. River 6. So the board reads 3-5-6-7-8 and I have 9s and of course we get into a raising war - he turns over 9-10.
Looking back over the hand there were a few spots where I could have done things better but how could I possibly put an UTG raiser on 9-10!!!!
But as Ghoulies says, these things happen.
