Early stages, flop the nut boat, unsure of my play

This is like the 5th hand in, blinds are still 5/10.

I am dealt A[img]/images/graemlins/spade.gif[/img] A[img]/images/graemlins/diamond.gif[/img] in MP. All stack sizes are effectively T1500, although I have villain slightly covered.

I'm just not sure that this is going to get the maximum extraction in all cases.

Pre-flop:
4 limpers JerZHoya raises to 80.
6 folds, Villain calls. 1 fold
Flop (board: Ac Ks Kd):

Villain checks. JerZHoya bets 150. Villain raises to
300. JerZHoya calls.

Turn (board: Ac Ks Kd 4c):

Villain bets 100. JerZHoya raises to 600...
