I agree with everyone else. A bigger reraise preflop would be inorder, I would probably make it 250-300. A small raise just screams big pair, you want him to think you have something like AK, just in case he is sitting with a middle pair.

After the flop, its highly unlikely that the flop hit him in any way (remember, he raised first, then was reraised and called). He either has a good ace (not necesarily AK, its early in the tournament), or a medium-high PP.

To sum it up, I would raise to 300 preflop, and if I was called I would make a small bet on the flop (a bet that appears weak) and hope for a reraise. If he reraises, its time for all-in obvious, and if he called, I would bet hard on turn (giving one cheap card is enough).

I would never check that flop though, since that only makes me seem stronger, atleast to people who have seen me play before. Besides, AA is only one pair, far from enough to go for a real slowplay.
