I would raise to $240 and fold to a shove.

Im a wuss but I would probably just call.

This is a classic spot where I would probably call but regret not raising after the fact.

I like shobute's line.

Without a read, I call.

He certainly can't put you on KT and hence could have about any Q, although I'd consider AQ as most likely but QJ possible as well as a LOT of other losing hands and some winners.

I don't think the river necessarily made his hand, as he may have hoped you have an overpair and had the intention of check-raising the turn. He could be floating JJ (or almost any PP) for that matter. I have trouble really putting him on a hand here without knowing how he plays. And it's difficult to do in these LP steal type situations anyway.

I'd like to call and see what he's playing and how before putting moves on this guy, although I do think you're ahead often enough to justify shob's line. I'm really calling mainly to see his cards with certainty.
