Do I check behind here and hope to call a small bet on the river if he has a set, or do I try and get some value from hands like KK, AQ, KQ, two overs+flush draw, etc. He just calls the original raise and the reraise, but from the play at these levels, I never really know for sure. I have no stats on this guy at all, he just sat a few hands ago.
