I don't have the exact hand history with me (at work), but it was fairly straightforward:

Full ring 5NL at Party

Hero UTG dealt AA.
I did my usual 3xBB raise of 0.12 (I'm trying to keep my preflop raises always same lately). Some folds, MP raises to 0.30, MP1 calls. I decide to go all-in as both MP and MP1 have buyin sized stacks. MP calls, MP1 folds. The five cards are laid down and are all low ball rainbow. I win vs his KK.

I realize I won a nice pot, but was this a good situation to go all-in? I figured it was since they both had good sized stacks and I had the best preflop hand.
