1) What are your thoughts with my check on this board? Any concerns about a check-behind?

I'd make a continuation bet most of the time unless youre pretty sure villian is going to bet when you check.

2) What is your interpretation of the small bet by villain?

A small ace, a flush draw, possibly a K or a bluff. I dont think you can rule out a flush draw just because of the Ah is showing. Some people like suited cards, even when they arent aces.

3) What do you think about the reraise? The pot is laying villain 2:1 odds. Am I pricing him in for anything?

That's the amount I'd usually raise him - his bet plus the total of the pot. I dont think an all in bet would be a bad idea either - I'd just rather try to build the pot here. I think 2:1 is the perfect size to induce mistakes.

4) This hand is HU. Should I have any concerns about the flush draw?

Yes I think there is a chance he has two hearts. It might not be his most likely holding, but its a possibility. If he does have two hearts and hits his flush, you still have a lot of outs for a boat. I guess I'd be more aware of the possibilty of a flush than worried about it.
