AK pre-flop, 4 handed $11 SNG Full-tilt

[Cali4niaRaisin]

This occurs frequently when shorthanded. I get re-raised and have AK...
(no hand official hand history, sorry).

Approximate chip counts:

Hero (SB) 4,500
BB- 3,000
UTG- 3,000
Villian (button)2,000

Blinds: 150-300

I have AKo
Villian raises to 600, Hero raise to 900. Villian pushes for 1100 more.

Now, I have odds to call if I put him on underpair. But, do you think its a better play to just move-in in over his initial raise, given the that I may have some FE (unlikely though bc he's shortstack). Also, What do you think about committing 1/2 your chips to a race when down to 4-handed.

Personally, i don't see how I get away from AK given the wide range he's pushing (bc 4-handed and he's shortstacked)

Any comments would be appreciated, thanks
