50+5 Bubble: Middle stack w/AKs in small blind facing 2 all-ins

[AA suited]

no reads on anyone since i was multi-tabling. and i'm doing this from memory since I don't remember which of the hundred SnGs i played over the weekend this hand was.

Blinds = 100/200
sb = ~2500 chips (HERO)
bb = ~4000
utg= ~1000
button = ~2500

i'm the small blind w/ak suited.

utg went all-in and button called.

Here's my thinking. Please tell me if it's wrong.

- I put UTG on Kx, Ax, or pocket pair. I put Button on high Ax, or pocket pair.

- If one has kx or ax, then he has one of my outs. I'm even more of a dog vs a pocket pair.

- I'm getting 2.3:1 odds to call.

Options:
1) Call, and check/fold if the board doesn't hit you.
2) Fold since I don't know what big stack is going to do. Also, hope UTG loses to get ITM.

What does the "book" say to do in this situation?

THX!
