FT MTT SNG - AQs on whiffed flop

[deankeaton7]

Villain is a little looser than he should be preflop, and folds a little too much post (unless he had just missed every flop he'd been in recently).

Button and BB liked to get involved in multiway pots and both had about 20k, but had not called 3 bets often.

Blinds 100-200 a25. Villain (with 8k) raises to 600 from MP1.
Hero (12k) reraises to 2k with AQss. Villain calls.

Flop is 9 7 2r. Villian checks. Hero? Thoughts on reraise preflop?
