All of these hands are one way hands....

Hand 1, I would have folded preflop, middle pairs (or middling cards in general) are pretty useless. You pretty much have to call the river bet, but you are probably beat. Looks like someone may have backed into a high hand from their low draws.

Hand 2, I even consider JJ a pretty middle pair, and it would take something nice to play it (except for free or button limp.) good fold.

Hand 3...

Something is wrong with your notation, you mention you are mp, but you act between the sb and utg....

"SB checks, Hero checks, UTG folds, UTG+1 folds, MP1 folds, CO folds, BB checks, SB checks, UTG+2 folds, Hero folds, SB folds, BB checks, MP3 checks, Button checks, BB checks, MP3 checks, Button checks."

that whole thing doesnt make any sense.

well... from here on out doesnt make much sense. I never see where you act, or make any decisions at all.
