Non-standard $100 SNG situation

[ChrisV]

$100 SNG on Party, 6 players left (maybe 7 but I think it was 6). Blinds are 50-100 and you're UTG with AQo.

The catch is: The BB has posted up allin for 20 chips. So total blinds are 50+20 = 70 chips and your minimum raise is 200.

What's your play? If you limp or raise, include what you plan to do if it is (re)raised.

Edit: Forgot to mention, your stack is about 900 chips. I can't remember all the opposing stacks but I think everyone has you covered.
