Hand 1: Fold.

Hand 2: Probably fold, reads would help immensely.

Hand 3: Fold preflop, I don't like the flop c/c either. At least you lead the turn, and I'd bet bigger on river. Fold looks fine as played if he isn't stupid.

Hand 4. Tough one, you really need to help us with reads. Totally read dependant, man.

Hand 5, bleh. Gotta call as played, way too much committed. I'd call flop raise and play the turn.
