Final Table: Call an all-in with AK?

[rms39]

Hi everyone. I'm new to 2+2 (first post). This hand happened about a month ago, and I'm still curious what other players would have done. Sorry for not having a good format, etc. I don't have the hand history since it happened awhile ago.

$100+$8 tournament on Pokerroom.com 9 players left (were about 350).

UTG: 23,000 chips
UTG+1: 15,000 chips
Me: $40,000 chips
MP2: $22,000 chips
MP3: 47,000 chips
CO: 14,000 chips
Button: 19,000 chips
SB: 17,000 chips
BB: 21,000 chips

Blinds: 1000-2000 (no antes)

I get AKos, and raise it to 6000 from early position. MP2 folds, and MP3 (the only player to have me covered) goes all-in over the top. It mucks around to me.

So far at the final table, I've "stolen the blinds" twice preflop without showing. The player who pushed was at a different table from me until the final table, so I have more or less no read on him. First place got paid about like most tourneys, the prizes jumped way up as you lasted longer, but going from 9th place to 6th place only got you a couple hundred extra.

Do you call or fold?
