The only hand I'd be afraid of is 66, can't see how he can have a 9 here after you bet the flop. Why are you not raising PF here BTW? He could have a lower A and think that the 2nd 9 solved his kicker problem or missed his FD and tries to bluff you now...
I'd bet a little more on the flop BTW.
Question is, how likely is villain to just flatcall twice with a set on a drawy board on the flop and an even more drawy board on the turn? His AF is at 2 so he is not one of those hyper - passive guys...
Value bet is good IMO, maybe a little bit on the high side but that depends on what you think villain will call here (I guess you think you're in front here, right?).
Your odds on the river are quite good, getting 2.4 - 1, so I think I call here, not liking it too much though.
