So, this happened yesterday. $55 buy in tournament in a local casino. 500 chips is the starting stack, starting blinds are 5/10, and it's the second hand of the tournament. No reads yet. 10-handed and I get dealt AA on UTG+2, UTG had limped, so I raise to 45, and two people call on later positions. Everyone else folds. The flop is 8d 5d 6c. I don't have A of diamonds. I bet 90, one players folds, and the other one raises to 225, then I think about it for a minute and I go all in, he snap calls and shows 88. Flop and river are Q and J. I'm out. Did I screw up here? Should I have known better and folded to the raise? Or did I have any reason to believe he was on a straight or flush draw, or that he had an overpair worse than AA? After thinking about it I think I should have folded because it was too early to be playing for my whole stack but my other friends think I did the right thing. What do you guys think?
