AQ on button deep-stacked vs. short stack's all-in

[FortWorthJim]

$400 live tournament in underground room. Start with 10,000 chips, 40-minute levels.

4th level, 100-200 with 25 ante.

I'm on button with 9,000. MP limps, cutoff goes all-in for 2,500.

MP is standard loose-bad, limping into a lot of pots. No reason to think he has a hand. Cutoff is competent, but could be steaming after losing a large pot a couple hands earlier.

Call, raise or fold?
