What do you do?

[Nottom]

Sitting in a UB multi-table tourney. It was basically a huge satalitte for entry into one of their Aruba satellite and only cost points to enter so lots of loose players. Additionally, only the winner would get a prize so just gettign into the money wasn't good enough.

Blinds are up to 200 400. I have around 12500 and am currently in the top 5 with 35 players left. Other relevant partys have ~4000(MP) and ~7500 (LP).

I'm in the BB and get A /forums/images/icons/spade.gif K /forums/images/icons/spade.gif .

Folded to MP who raises to 800, folded around to LP who kicks it up to 2k.

What should I do? (what I actually did coming soon)

I re-raised all-in hoping to fold the MP and figuring it's always better to make a big bet with AK then have to call it. Both players called revealing 55 and AA. A King came on pretty raggeddy flop including a 5, so if I would have just called I would have probably pushed in there and still lost.
