$22 MTT / Call a huge all in with A/K Suited early on with chips?

[ffr]

Early on in a Stars $22 NL Hold Em MTT I was up in chips at 8,500 (average was only 3,500). I'm on the button and I'm dealt A/K suited. Blinds were still only $100/$200. A player in mid position with 10,000 in chips shoves all in. Everyone folds quickly to me on the button.

What do you do here with A/K suited. Call or fold?

I just got moved to this table so I didn't know much about this player other then this large overbet he is making.
