******************************************************************
Right after the hand the guy I beat starts saying things like 'what a joke', 'I can't believe you f*&&^^ called' and a bunch of things I'll leave to your imagination.
Let's look at the hand. PF I was a 65% favorite. The flop hit me very strong. I had two overs and an open-ended, so while I didn't know for sure, I likely had 14 outs when he pushed and I'm getting 3-1, so it was basically an autocall. As it turns out my outs were good so we were almost exactly 50/50.
My point is that he had no reason to go off... in fact, there's never a reason to go off. Usually the person who gets mad has no reason to be mad. This is poker. We all win when we're ahead, win when we're behind, lose when we're ahead and lose when we're behind. And you run the risk of looking stupid. Either because you're a bad sport, or in situations like this case, you are just plain wrong when you're complaining so you look really stupid.
So the next time you bust out, just shut the (*&%$% up and walk away.
