$22: First hand KK

Okay, it's the first hand of a $22 10man tournament on UB. I am in middle position and have KK. All stacks are obviously equal and blinds are 5/10.

UTG raises to 70, 2nd position calls, 3rd folds, I raise to 200. It folds around to the SB who goes all in for 1500. It folded around to me and I called.

He turned over AKs and flopped an ace.

Did I play this wrong? I realize I probably shouldn't fold KK preflop and I did get in as a favorite, but sometimes I'm surprised by the advice I read on here. So, did I do something wrong with this hand? Or did I just come out on the crappy end of the stick?
