There is no way you can give this up at all in a pot of that size. The board is not very coordinated and looks like it might be good for you based on the preflop action. Were you against TT, JJ, or QQ?

The bottom line is that you may only win this pot 50% of the time, but against 3 other opponents that is a huge equity advantage. You just have to get your money in there and hope your hand holds up. Just my take though. Someone may have differing opinions. I just know I'm not folding AA with that preflop action and that board when the pot is almost 30 big bets.
