Midway thru $12 Turbo on Doyles, AQo in BB.. what do we do?

[Poker Orifice]

We're playing a $12 buyin 6max Turbo ($2kguar.) on Doyles/Cake.
36 paid of 181entrants

There's 82 players left and we're sitting in 21st with 6,501 (~26bb's).

Here's the hand:

Plyr 1 (UTG) folds
Plyr 2 (3,170) raise to 625
Plyr 3 - folds
Plyr 4 -(SB) "sizzlinbetta" (7,080) shoves ALLIN
HERO (BB) "me" (6,501) with AQo - ?????


Player reads - Plyr2 is Lag player they're obviously raising here with intentions of getting it allin.
SB (sizzlinbetta) is an aggress. MTT reg., see them playing on Pokerstars alot (MTT ~2,500 tourneys played,avg. buyin $70 w ~$150k in profit, SNG's 28,000+ games played avg.buyin $110+, $150,000+ profit (roi+4%)) & know they'll get it in here on a fairly wide range (earlier they got it in vs. UTG raise (both on decent-sized stacks at the time) with A7o & sucked out vAK), the shove tells me they're hoping to isolate the UTG player (likely as wide as ATo+, 66+).
So, with AQo in BB.. what do we do? We're assuming that utg is never laying it down.
(we win this pot & we're in Top3)

I usually tend to take the consevative route but with it being a Turbo & thinking I wanted to make a go of it with a bigstack.. I shoved in the pile.
