Here is a hand which probably should have told me to quit immediately.
Last night in a 2-5 game I called off $100 on the river with jack high.
V was drunk and playing very agressively, but we have played quite a few hands together over time, and I don't expect him to run a stone bluff against me.
V straddled, several limpers and I called the straddle from BB with J-9h. Flop was Q, T, 2 with one heart. I check, V bet the flop $25, rest folded, I called (could have raised of course but decided not to). Turn was A rainbow. I checked, V bet $50 I called. I never looked back at my hand and somehow I was saying in my mind after the turn "ok if it's a K or a 7 on the river I'm probably good". River 7 rolled off, I checked again and he bet 100, and I was thinking - hmm, should I shove or not? He could have KJ, and probably would not call a shove with worse than the same straight (he was drunk but he's not a fish). I wimped out and called - he showed two pair and I rolled over my jack high, noticing at that point that I had completely misread the hand/board situation. A couple of regular opponents said - "wow you called with Jack high - must have had a read". And I had to say, no just being a moron.
As most respondents said in this thread if you think you are playing your A game you should play on. But what if you are playing your F game, but it's early and still looks like a good game? I played on
