Strange AKs hand

[trigeek08]

Villain1 in the hand is 60/16/3 over 60 hands. The only thing interesting i have seen him do was limp/3-bet from utg w/AA.
Villain2 just sat down.

Villain2 bets, utg folds, villain1 calls, hero raises, villain2 3-bets, villain1 calls, hero calls.

Turn 4[img]/images/graemlins/spade.gif[/img]
Villain2 checks, villain1 bets, hero raises, villain2 calls and is all-in, villain1 calls.

River 4[img]/images/graemlins/diamond.gif[/img]
Villain1 bets, hero calls.

How does the raise on the flop look? Can I fold to the 3-bet, or should I cap it? When villain1 lead the turn, I had a hard time putting him on a hand that I didn't beatand popped it, but then was not as confident in my read when he lead the river.
