AK in SB late in Tourney at Foxwoods

[Dr_Jeckyl_00]

I usually post/read in the STT forum, but I played my 1st B&M multi-table tournament (no-limit) at Foxwoods on Friday and thought this forum would be more appropriate.

I made it to the final 8 tables (out of about 23-25). I had just moved to a new table and had no reads on anyone. The blinds were t200-400 (about to increase to t300-600 next hand). There were 3 large stacks including me (I had t5500, and the other 2 looked to be about t6000-7000... the other 6-7 players had small stacks.) I was in SB w/ AKo, one of the big stacks bet t1200, it was folded to me. How should I have played?
