This reminds me of the limit holdem concept of calling on the river with pot odds because you think you will have the best hand x % of the time vs how much you have to call to win the pot. The catch to this is that when there is a caller between you and the better, your hand is not going to be good nearly as often as you think. I think this could apply to NL somewhat because your hand has to be beating 2 other hands. 3 hands seeing all five cards, a pretty hefty $60 river bet, a caller, and you sitting with one pair. Any reads on a loose caller? I might be weaktight, but I'm folding this one. GODAMMIT the last 2 pieces of pizza just fell off my plate onto the floor before I even got one!

Anyways, I imagine the better bluffed with a missed club draw, the caller thought his KQ was good, and you folded not knowing this. The showdown pisses you off and you post the hand. That actually looks pretty good, but I just don't know if your hand is going to be good anywhere near often enough to make this call. What did the showdown look like?
