Usually there would be at least one boat on the river, but everyone checked the turn. It is rather unlikely one would have an AAxx-hand because there was no raising PF. On the other hand, CO already called the river bet so he should have something.

I didn't like the so I believe my hand wasn't raising hand PF, especially from the blinds. I called on the flop because the bet was only 1/2 pot. If there had been betting on the turn I would most likely have folded. When played this way what would you do on the river?
