I guess I just don't get it. The first thing your post says is that this guy is a donkey at 53/30ish/4+!

So given this guys stats, and his very high AF, I don't see how either of these aren't insta-calls. Especially given how cheap these river calls are.

If you said villain was 10/4/0.85 nitty or something, thats a different story. But even in this case, I still think I would call both of these. I might find a fold in hand 2, but still call hand 1 for sure.
