I am a inexperienced (horrible) NL player but my thinking was pretty similiar (I was typing up a response but it sucked so I stopped).

Basically i think that preflop, flop, and river are all completely standard and fine.

The turn is the interesting street. You fired at the flop and it might have looked to him like a standard CBET. You're checking of the turn might appear to be weakness and it's also a possibility that the A hit him (AxKh totally came to my mind too). So it's not really a surprise that he bet at it, in fact it's pretty clear you wanted him to bet at it since you check raised.

The question is, did he call on the flop with a real hand or draw? Or was he just planning on trying to take the pot from you later since he had position and possibly a read on you?

I think as played it was very +EV in this situation most of the time. If he had a couple of hearts or made a straight on the river than so be it.
