wtf at folding AA 110bb deep... COME ON

I'm going to have to agree with slider here regarding AA. I'm not sure that felting is a certainty, but at least calling the check raise and evaluating on the turn, especially being in position. Theres no doubt that a lot of his range includes TT+ and possibly draws, though I'm fairly confident, given his PF play, that he wouldn't call an UTG raise with small suited connectors. But, like Slider said, you cannot just immediately narrow a villains range to exactly a set just because he check raises you on this flop.
Truthfully, the fact that the flop is all low cards, makes him holding an overpair even more likely. Many would take his line with 99+ on this flop.
