Villain is 36/5/somewhat passive post flop, nothing special seen.

My thoughts;
- Flop is a WA/WB situation and I want him to bet into me again on the turn with AK (not likely), KK and QQ.
- Same goes for the turn except QQ now has me beat (given that I have the Ac I'm not afraid of giving a free card to the flush draw on the turn).
- I don't think he'd check a set to me twice on this board, so I bet half pot hoping to get a call from KK or AQ.

How's my line?
