AKs on the button

[Urchin]

I'm pretty new to MTT's and this was a $20+2 with 68 people. We are 9 handed and here are 17 people left with blinds at $200/400 and average stack of about T6500.

I have A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/spade.gif[/img] on the button with T6000.

It's folded to MP2 who goes all in for T1700 (no read)

MP4 goes all in for T2900. (my read is a LAG)

It's folded to me and I think the blinds are tight and both have me covered.

Only 1-10 places get played. What's the correct move here?
