He knew he was up against AA. Thats why he layed it down and thats why he is there an your watching it trying to say its bad play because you don't understand...A pro will tell a beginner not to lay down KK... ever!!... Personally I don't! I would have to die in my chair to fold KK pre flop...But this guy did and he got it right. The flop made KK the best hand but the all in call was preflop and he made that amazing lay down pre flop.
