Hand 1: Gotta raise here, $28. You probably have the best hand.

Hand 2: This is ok, based upon history between you. You probably have FE and even if it's a race you have good pot odds

Hand 3: Fold PF. What the heck are you doing? You should also bet flop, and raise the turn. I probably call river expecting to take it down. You can't just give him credit for the 8's.

Hand 4: I don't like the raise out of the SB with such an easily dominated hand. I think you fold PF.
