for me AA wins a little looses a lot, after all its just one pair and at $100 thats usually not enough. He called two bets of two thirds the pot wihout raising. that could well mean his hand is so strong he doesnt mind giving you a card, otherwise he should raise. If he is raising with all sort preflop then a crappy flo might have hit him, this flop misses every TAG.
In this spot i fold
