400 NL-- QQ on the river, bet or check?

[JasonP530]

400 NL online. Villian has ~270 when the hand starts, and I have him covered.

I raise to 15 after one limper, he calls out of the BB, and the limper folds.

The flop is 953 and 2 diamonds. He checks, I bet $25 and he min checkraises to $50. Obviously, this is worrisome, but with position, I decide to see what he does on the turn. Should I just fold the flop most times there?

Anyways, the turn is a 2, and he bets $50. I think it looks like he is sucking me in, but it could also be a continuation of his raise. With the amounts he is betting, he is unlikely to get all in on the river, so I thought it strange, and called.

The river was a 2, and he checked to me. I was actually planning to fold if he pushed(I think) Should I check behind, or value bet about $100, when he has $180 or so left? Any thoughts about what to do in the hand before the river?

Thanks,
Jason
