Preflop with AK at final table in PS 20 table SNG

Haven't played many MTT, mainly 2 table SNGs, but have been giving these 20 table deals a shot. Played in like 15, with a couple ITMs, but no final tables. Last night, the poker gods were good early and I doubled up twice on first orbit.

Down to final table with big stack LAG to my right. Everyone else seems pretty tight. What is my move here preflop?
