In hand one, I call turn and river sometimes. These LAGGY idiots love to get wierd, but folding turn UI isn't bad either.

Hand 2 I think you should call the river. I think that he has some trash hand that he has been peeling with and now that you have given him the chance to bet he is going it. You have the nut no pair, and I think that if he had gotten any piece of that board he would have raised, right?
