AA did I raise enough?

[johnny005]

I was playing a 20+2 MTT the other night on party and I went out with pocket aces, It was pretty much my own stupid fault for not thinking before clicking the call button... I guess I wont do that again. Anyways here's what happened
I HAVE T5000, And villain has me slightly covered, I think the average chip stack at that point was about 2400 maybe.

I was in middle position with A-A, Blinds are 50-100, UTG2 raises to 350, I raise to 850, Everyone folds UTG2 calls,
POT=1850
FLOP 2c-kd-9s
UTG2 checks, I Bet 1700, UTG2 check raises all in.....!
And guess what? I call. What would u guys have done? I should have folded, and I think I would fold over and over again, I didnt know the player to well he had just moved to my table.. Let meknow what you guys think
thanks
