Does the villain have a habit of limping with strong aces in middle position?

I think the only hand you're going to see here that will beat you is A7, 77 or possibly A5. Is the villain capable of raising the flop with KQ?

If I have a decent read I'm going to try to milk my opponent as much as possible. If I have no read I don't mind 3 betting the flop and ending the hand right there.

In this case, assuming no reads I'm reraising to $12 and calling a push from an average party player. If he smooth calls the flop I push the turn.

I don't understand why you think he has a big ace. His preflop limp typically means something like A2-A9 suited, or A7-ATo. it's also possible that he limped with AA and you got really unlucky, but them's the breaks.
