Did I misplay Aces? (low content)

[jumpthru]

Stupid 30 person touney, $20 buyin, 10 minutes awful blind struture.

Cards go in the air, and first hand I get Aces. I raise 200 everyone folds and I think I won the 25/50 blinds. I flip my Aces face up and apparently the guy in the 1 seat (I was in the 9 seat) had actually called (I couldn't see past the dealer)...

My hand was called instantly dead for being exposed and the other guy gets the pot. Other guy had KK and I would of most likely doubled up first hand. Was on tilt the rest of the day.
