2/4 NL - I feel like giving up with Aces HU

[Burdzthewurd]

2/4 FR

I have $512, Villain covers. Notes on him say he triple-barrels his draws and will float with just overs in raised pots, but never been in a 3-bet sitch with him before. I can't see raising river being all that smart.

UTG limps, 3 folds, Villain raises to $12, Hero raises to $40 with A[img]/images/graemlins/spade.gif[/img] A[img]/images/graemlins/club.gif[/img], 4 folds, Villain calls $28.

Flop K[img]/images/graemlins/club.gif[/img] K[img]/images/graemlins/spade.gif[/img] 7[img]/images/graemlins/club.gif[/img]

Villain checks, Hero checks

Turn T[img]/images/graemlins/heart.gif[/img]

Villain checks, Hero bets $60, Villain calls.

River 7[img]/images/graemlins/heart.gif[/img]

Villain bets $32, Hero calls.

Anyone check behind turn and call any river?
