I bet 1000-1200 because I think only hands you're behind that just called the flop are AK and 89. I would think that two pairs and sets would've raised the flop. It's likely villain has OESD + middle pair/bottom pair or AJ/AT. I'm checking the river. If villain calls turn and has a single pair, he'll probably check river after you check. I think it's unlikely villain is drawing w/o a pair in his hand.

I don't like checking the turn, because villain will probably bet most hands, and you'll have to call a bet from villain in the 1000-1200 range. You might as well be the bettor. I probably ditch hand if he raises turn.
