Wow, I almost can't beleive what I am reading. You have to now some one pretty well to lay down kk preflop. Either there is more to the story. Or tommy made one of the worst folds of his poker playing life!
If Im in that situation(me having AA) I make 800 to go, and then baring some kind of disaster flop I push on the flop. This is assuming the game is rammin and jammin like tommy says.
