I think the chances of him holding AA here are pretty limited given you hold the other two.

Plus, if he was concerned with your re-raise pre-flop, he is going to crap his pants when you open push that flop. If he does have QQ or KK here, why not check or make a weak lead at this pot and let him be the one who shoves his chips into the pot. I think you are possibly providing him with an opportunity to fold here.
