Should I fold AA pre-flop here?

[spoonitnow]

Blinds are at 100/200 with no antes.
The payout structure is $5, $3, $2.
Four-handed, here are the stacks before blinds:

BB 5000 (Hero)
SB 1000
BU 100
CO 7400

We're dealt AA, the CO shoves, and it's folded to us. What's our play?

Any reply that doesn't include some range for CO and some ICM calculations is going to get deleted.
