I'm so confused, 8/16 river line

[Xellos]

I have no idea where 8/16 hands are supposed to go, I was reading hands on this forum, so it's easier to post here. It's a live game, villain is new to the table, either coming off a broken NL table or just arrived and waiting for a NL seat. The point is he's probably a NL player. So far not much of a read on what kind of cards he plays, which means he probably plays tighter than the average idiot in this game.

3 limps including villain, I raise on the button with K[img]/images/graemlins/spade.gif[/img]Q[img]/images/graemlins/spade.gif[/img] and the blinds fold amazingly. Villain points at his cards and tells the dealer "give me some of this" and I decide that I'm not going to have any of this nonsense, so I tap my cards and tell the dealer "no, give me some of this".

Checks to me, I bet, 2 folds and villain calls.

Villain bets, I value raise my nuts, he thinks for a couple seconds and calls.

Villain bets, I'm thoroughly confused, but I still like my hand quite a bit here.

Raise/call a 3 bet? Raise/fold? Call? Fold face up and slap my penis on the table?
