Alright, no reads on villian. He plays the hand quite strangely. The river is aweful. He check raises a river blank (unless he has 33 which doesn't really fit). I'm getting great odds to call. Should I call here just because I can't figure out what he has or can I just assume he hit something because the pot is protected and the move is so strong and go ahead and fold?
