Live AQ hand

[davidross]

Played my first live tourney in a year today, $1000 buy in, 150 runners, top 30 take their chipsto Sunday where they meet another 30 and start again with blinds at 100/200.

I have 14K, with blinds at 400/800 and around 2 minutes to the next level change. I'm in early position but with knockouts and 1 empty seat I'monly 4 off the button. I raise to 2K with AQ and it's folded to the BB who has just come from another table, and is playing his first hand. He has around 10K, says "raising my first blind?", looks and raises to 4K. What do you do?
