I was in a poker room at Atlantic City and the following came up against me and the chip leader. It was a 5/10 NL and the chip leader raised it to 25 and 4 ppl incl myself called. I was holing AJ and the flop came J,6,8. I checked and he raised it 125 to go everyone around me folded and I raised him to 250 to call, he called and the turn was a 8 making the board J,6,8,8. I checked and he looked at me and said all in. I was thinking in my head what would he have? AA KK QQ I did not think he had because of the small pre-flop raise. mayeb TT or 99? After thinking it over for about a min i decided he had TT and called my 700 sitting and front of me and he flipped up JJ. I was shocked and hit myself in the head for not considering his set of JJ. How did I play this wrong or was it just a really hard decision?
