I think Hand 4 is the only one that's terrible, the rest of them are really OK even though I might play them a little bit differently.

Hand 1, he's only seeing the flop with one other guy. I would find a new seat and stop raising 89 suited when a calling station has position on me. That being said, once you saw the flop, you were probably doubling this guy up no matter how you played the hand.

Hand 2 is standard unless you've seen the guy make one of those stupid little "I have AA" re-raises when he didn't have anything.

I think that with your read, betting $20 on the turn on Hand 3 is probably a waste of money, because a good aggressive player might raise you with any two cards here. He knows what you have and he knows you can't call a raise. If your opponent is not capable of a bluff raise then I like the way you played the hand.

Hand 4, bet the flop.
