I think that I have seen previous posts that indicate his 5-bet of your check/raise on the flop was polarizing, and that he was saying he has a monster or he's bluffing. As the first hand in the tournament, unless you knew for sure he was a donk, the correct move is to fold on his re-raise. You have lots of time to play if you fold. I think your check-raise on the flop was a good move by asking him the question, but you weren't prepared to listen to the answer. Tough to fold AA, but there is a lot to be said about fleeing to fight another day.
There aren't enough fish in the see to 3 bet this flop with, say, A10. He has you beat, or at least in his head assumes he has the best hand. Do you really want to risk your entire tournament and stack on the first hand playing psychologist of whether his belief of best hand is true or not?
Not me.
In fact, if, for some reason (pot control possibly) I have checked this flop, and he bets what he does, I would argue that the PRO optimum strategy is to eject right then. Who in their right mind faces a bet such as yours preflop followed by a check that decides to lead out the way he does on this board? No one that you're crushing, that's for sure. You can get lucky and be ahead, but what are you really hoping to be against when you check/raise JJ QQ KK? Very few players would've taken that line with you with that holding for 2 reasons:
1) They would have tested you preflop with a 3 bet, even if smaller sized.
2) If they thought they were trapping preflop and had the edge, they hate this flop as much as you do. They're more likely to check it back for pot control than they are to put out a feeler bet.
All that being said, you got the information you were apparently looking for, as he said, but you refused to listen. IF you perceive his first best as a "feeler bet" his 3 bet of your check/raise PROVES it is not. There are three possibiities here:
1) You're dead.
2) He THINKS he is ahead and wants to play for stacks and you have to navigate that mindfield.
3) He THINKS you're weak and he can blow you off the hand.
IMHO, #3 is much more of a later-stage strategy, not usually reserved for THE FIRST HAND OF A TOURNAMENT. So you really only have two options. Either you're dead or he thinks you are. I can find a better spot to pick up chips than that. You should be able to, too.
