Based on the read, you're looking at a flush or set. It's gotta be the set. I think he's getting weak/tight at the turn & river. I don't see a rock c/r the river. Based on his slowing down, I put him on a lower flush like Q-high. I would probably be checking behind him. I'd bet/fold or just check it down. It's a small pot. I think I'll take a free showdown.
