Slowplay of AA's is a recipe for disater....bump that puppy up much more PF....
The only exception I take is when I am in the blinds and it is already isolated....then Ill make it cheaper to go.
Sure youll win a lot more small pots, but you'll loose a lot less big ones. Especially with all those people in the hand on the flop....you have to figure 1 of them would have cracked your aces pretty regulary.
