5 players sitting at NL100 6max on stars

Villain's PFR range is pretty wide, he was something like 25/20 and definately splashes around. Havn't seen a huge pot with him involved, but then again my reads probably suck. We don't really have any history before this hand. He has $102, I cover.

UTG villain raises to $4, 1 fold, I make it $13.50 straight with As8s OTB. Standard fold I know, but I have a pretty tight image and expect to just take it down pf. Blinds fold, he calls. He probably has some pair or a big ace more then likely. He puts me on a big pair more then likely. Pot is something like $28.

Flop 2c Ad 5s. Villain leads for $30. Bleh. I really think I'm good here. There's obviously no value on a push though since he can't continue a bluff if I do so. I think there's a good chance he has some mid pair trying to move me off QQ/KK. He could also be playing a hand like AQ/AK fast, thinking I won't expect it with a hand like QQ/KK. If he continues on the turn, I tend to think that MORE THEN LIKELY he has it. I would be VERY shocked if he had a set.

Turn 6s, giving me a backdoor draw to the nuts. He pushes his last $59 into an ~$86 pot. I really think I'm beat here, and I doubt he expects me to fold after calling on the flop. But I reason that the combination of a bluff and that I probably have 12 good outs here makes this play +EV. I call.

Yes, I know I'm a fish. Thoughts on the hand?
