Hand 1 raise the turn. He'll call you down with any pair. At no point in this hand should the though of folding ever cross your mind.

Hand 2 I probably check/call the river. I'm not sure where I'm at and I'd want to give him a chance to try and bluff. I doubt you beat any hand he calls you with on the river, so just check and call. As you played it, I pay it off.
