By not raising AA you're passing up a chance to get your chips in with a huge amount of equity. You've got opponents paying dearly as huge dogs (see also: The Fundamental Therom of Poker). If you limp you run the risk of letting the blinds and loose limpers break you with some freak two pair. Are you really capable of folding AA on a board that reads 952? Because the BB played 95o for free and has you hammered. I highly suggest you read Super/System's section on playing AA and KK. I jam AA up 4-5x each time when I open, and I'll overbet the pot if I have limpers before me and half the table ahead of me. What I'm looking for it to take the pot right there, uncontested, or for someone to put me on a steal and play back at me. I do however limp UTG and UTG+1 ~10% of the time. And when I do I play them slow unimproved. It's only a pair afterall.
