This guy is a decent player, but I caught him playing weakly.

My thoughts:
1) $4 on AT suited is probably not the best play by me. I'm interested in how others would play that hand in that position against a loose passive table. My objective was to get multiple callers, but don't let the blinds see a flop for free.
2) His $2 bet on the flop means he's afraid of the flush, or hopes we are.
3) His $6 bet on the turn into a $20 pot is really weak. If he's got a hand, he's got to bet half pot or better to drive out the flush. If he's afraid of a slow play, he should check. At this point, I'm thinking he's got a weak pair. I thought maybe small flush, but he's clearly afraid. Doesn't want to drive me out, but doesn't want to give me a free card either.
4) Poker tracker shows that this guy had folded to river bets 4 times out of 4 - every time.
5) Fourth diamond on the river is a good card for me. I hoped he was thinking I held on because I had a big diamong, and now the board makes my "flush". I bet $8 here because I didn't want to make it look like a big steal and because I didn't want to lose anymore than that. I figured there was a better than even chance he would fold, so I risked $8 to win $16. If he's got the big diamond, I fold to a reraise, but his previous play makes me believe that he doesn't.

After the hand he IMs "you are sooo lucky". I replied, "I feel lucky".
