hmm.. two river decisions

Hand 1) I fold turn and call river like everyone else said. It may be smart to raise river against certain opponents, but I think the generally correct play is to call.

Hand 2) I don't know that you necessarily need to bet this turn. My instinct is that you do, but this could be WA/WB and it seems to make sense to check/call. My main problem is that I really have no idea what villain could be holding here. I don't mind how you played it.
