The river looks good, but simply for a value point of view. Other than AQ, I don't think there's a hand Unknown will fold for 2 but call for 1 after checking the river that beats you (which is an odd thing to say about someone called Unknown but oh well). OTOH, he probably doesn't have a K or similar monster or he would have bet, so the real question is whether you are ahead of the nut and whether you make more going for an overcall from Unknown.

Nut is probably betting lots of hands, many of which you beat, and I feel a player of this description is waking up earlier with a K or monster earlier. Likewise, I don't see unknown overcalling with JJ here very often or something similar, so not really missing any bets. Seems like the best way to get the most money into the pot with the best hand.

What are you doing if nut 3-bets? Call, right? Or is he not so nutty that you can fold 2nd pair to a 3-bet ?
