To quote Herm Edwards.
Hellooooo you Plaaaay to WIN the game!
AA is far too valuable to just let it sit.. No matter what situation you're in at a tournament.
We did the math, must have been about a year ago, and AA is the only hand that even if all 10 people at the table are all in, that AA is the mathematical favorite to win the hand 100% of the time. That's just too good to pass up
