Please Ignore all posts made by me in this thread except this one. I totally misread the flop action. I thought that the player who checked/3bet the flop was the player directly on the hero's right. Given the fact that the player who 3 bet the flop is doing so without UTG+2 commited, this looks more like an elimination play, so the villain could easily just have top pair here. Now I think if the hero caps and the villain donks the turn on the ace card, the hero is correct to fold with no read. But if the Hero just called the flop with the intention to raise the turn, the hero cannot fold then since the villain was probably going to bet the turn no matter what card hit, then the hero should just call down in this large pot since there is nobody behind him to eliminate. I apologize for butchering this hand so badly.
