Bubble: All in with AA

[twang]

I played Pacific's 30k guaranteed last night.

91 players is left (80 gets in the money) and I have a slightly above average stack (31st I think). I get AA in early position and make a min raise. A LP player with same stacksize as me reraises. I move all in.

I think this was a very +EV move, but I'm new to MTTs so I'd be intersted to hear what you say. Good or bad?
