Hand 1: .. What range do you put opp on?
A missed draw or a stupid slowplay. Villain showed AJ, weird.

Hand 2: Is that a min-reraise? Ugly stuff. I'd raise the flop much bigger. There's a decent chance CO has a bigger flush draw so a big raise would be good.
I minreraised so shortie could push and then I could see CO's response for cheap. Notice stack sizes; I'm not getting 200BB all-in vs. CO.

Results: Shortie 64o, CO folded AA

Hand 3: Missed draw, T6s or something. Should've chosen push/fold at the turn I guess.

Hand 4: Folding the flop is probably +EV against this opponent. Jx is not very likely.
