Re: AA hand id never think to play like this...
 

I'm with the 3-bet the turn camp. There are just too many draws that can hurt you and you really would like to get the capper out. I don't think you are going to see a flush here very often as I think both a big flush draw and a flopped straight are going to play fast on this board with this preflop action. I'd assume overpair or pair+draw here. But regardless, the board is too scary and the pot is too big to let the 3rd play in IMO, especially since even in the event you *are* losing to a straight or flush, you have outs.

Edit: BTW, I don't think he played the AA bad at all given that board.
