Mini-Raise blind steal, I'm SB with AKo...

[meep_42]

What's the correct way to go forward with this hand?

100/200 blinds, 60 players left, top 15 get paid (Qualifier, 1-12 get into the main tourney, 13-15 cash)

I'm SB with AKo and about 7000 before posting.
Action folds to the unremarkable button who min-raises to 400 with about 5000 behind.

Smooth-call? Raise it up to, say 1200? Jam?

While I realize this is probably a retardedly easy question, i'm just getting into MTTs, as I find them a lot of fun. Any help on my what thought processes going into the action would be appreciated.
