Hand 1 I play the same if I won't expect to get bluffraised on the turn much. Othwise I'd c/c turn turn and have a tough river decision.

Hand 2 is very player dependant, tough to say anything on it. In general, looking at his stats villains seems more a calling type with good hands than a raising type with good or bad hands and he can have lot's of 9's here or AA-JJ sometimes. I think you can fold, but it's kind of a non-decision because it's all about how often you think he's doing this with smaller PP's/air. Some do it a lot, some never.
