(Newbie grunching) Let me guess: you posted this hand because villain had a small PP and flopped a set. He then saw your flop raise and decided he could maximize his winnings by letting you do the betting.

I don't care. There's no obvious reason to think you're behind. Against an unknown penny player, I bet the river. I make the crying call even if checkraised on the river, say nh and move on.
