On the turn I'd go ahead and bet 120 or so, this makes it much easier to get your whole stack in regardless of what villain holds.

Say he has a K too. He's most likely not folding, he may even raise you. If he just calls the turn then you can check or bet the river depending on your read. If you think he's going to bet a K or a busted draw on the river then a check would be good.

If he has a draw, he's calling a pot bet.
The key is making it look like you're scared of something. If he has some kind of draw you want to make it look like he's still drawing live. If he hits his hand on the river you stand to double up with any line you take on the river. If he misses on the river he may bet if checked too, though I think it would be a difficult bet to make since you've already caught him earlier.
