[well named]

It's close, but I think I fold without a specific read that he would bluff a significant amount of the time. He's aggressive postflop, but not so much preflop, so you can run into 99+ and there's only one smaller overpair that doesn't have you beat, which means that the only part of his range (aside from air) you are ahead of are draws, but there are just not enough combinations (and not enough equity) to make up for all the other hands. I'm not certain but I think i'd put my calling threshold for overpairs here to like JJ or maybe even QQ.

I guess a lot just depends on how much you think he will bluff. A high AF doesn't necessarily prove a lot of bluffing ,it just indicates he doesn't call much.
