AK big preflop overbet

[kdotsky]

Stars $10 rebuy. I've got 6.5k, blinds are 75-150. UTG raises to 450. THREE people cold call - one EP and two MP. Two of them have about the same as me (including UTG), a couple have about 8k. I have AK offsuit in SB. There's 2K in the pot, I don't want to play it multiway, and a pot-sized re-raise is a big chunk of my chips. I figure the only one that could have AA/KK is UTG since there's no re-raise, but not likely since I have AK. I decide to push my 6.5K into the pot of 2K, figuring I have some folding equity, but I'll probalby get called for a coinflip situation. Is this unnecessarily risking all my stack? It seemed to be +EV to me with all the money in the pot. Thoughts?

I ended up getting called by QQ (not the UTG raiser) and winning, which launched me pretty deep into the tourny.
