How does villain play AKh here, I think that is the hand to think about. I could really see it being played exactly like this.

Not really sure what else plays out like this either, 77? We assume AA and KK do more preflop, QQ can't cold call like that, AKo probably at least reraises somewhere. Unless he is horrible, AKh and 77 are the two hands I see most often on that river. Maybe AQh.

I guess I would like to know more of your thoughts, because depending on how often you decided he had AKh, AQh, 77, you might call this on pot odds, you might not .
