ugh... -2.5 buyins over 500 hands at lunch. I had one set over set for 130bbs that was standard, and i bluffed off a full buyin. I had KTo and i raised a QJx 2 spade flop bet. 3rd spade comes on the turn, i bet 2/3 pot, and push a blank river for 4/5 pot and get called by AQ w/ no spade. I think it was a good spot to bluff, and the opp seemed decent enough that he would give me credit, but whatevs. Everytime i move up to 100nl i seem to bluff way too much, so i just need to play my cards and not worry about getting fancy.
