Playing the opponents hand and not yours.

Dont ask me, I called a raise of 6k the other day with 89s thinking the guy had AK-AJ. I was on the button and had a 71k stack to do this. I hit TP with the 8 and pushed on the guy, he shows AA and I'm kicking myself, still. Stupid, Stupid, Stupid. Feel free to chime in.

Personally, I think this is a major part of the game though, good read or bad read. I always have a hard time putting someone on AA - JJ still. I usually only can "see" it when they limp in and then reraise me. I always try to put a hand to the player. I dont know how you have played without doing this.
