I think you need to bet more on the flop. Make it about 200 and jam the turn. Given the way you played it though, I'd push in my last ~250 chips on that river and pray he's loose enough to call with a worse ace with no heart. I can't see checking the river being much good, since it doesn't look like you'll be able to induce a bluff from him, and you just can't fold this ~1000 chip pot.
