Villain is unknown. How is this line? Of course I intend to call if he shoves over for whatever he has left. River bet is too small I think but I think he'll get it in himself with 2 pair hands.

I don't think he can ever really have a flush here unless he sucks.

Here's another hand with same villain a little later. The previous hand he 3bet me from the button, I 4 bet and he folded.

Easy fold here on turn or? I think there's some leveling going on here. Would he check back JJ on this wettish flop ever? I doubt it. And I have the As so he cant have like AQs.
