Tere is no worng way to play AA other than to not bet them and lose value. The professor likes getting as many people in as possible which means when he hits his set, nut flush etc he will make wayyyyyy more money then if he bets big pre flop and chases all but one away. That being said - yes u will win more HU but win less money. So there really isnt a proper way to play them unless weird circumstnces come up like ur short stacked as shet and near the bubble or other. comes down to style/preferance in a normal situation. Go big go HU or slow play them (still betting but smaller) and try to win a huge pot. Odds are with you either wayyyyyy - ur ahead pf.
