Well in berzergers exarmple it is actually correct to fold AA. For the reasson that your not trying to accumilate chips in DoN's. Most importantly by folding here about 95% of the time you'll cash as 5 players are very likley going to be bust after the hand in question. Call what you may win 50% of the time? Folding here you cash alot more than calling.
Question for Berzerger:
Are $53 DoN's really as soft as that exarmples making it look?
