You gave this guy way too much credit and got paranoid about his loose play. Cordinated board or not he was the SB and had to pay $25 to see the flop. No way he had J,9 but I guess a boat was possible. I think you dicked around too long with your aces and he got into your head. Odds are you got bluffed out IMO and should have moved in. You didn't have the stack for the game anyhow like Steve mentioned.
