Classic Tournament Exit

Today's $2000 no limit hold'em tournament gets off to a slow start for me, but after struggling for three hours I have a slightly smaller than average but still quite healthy stack and about 60% of the fields is already gone.

I pick up two aces for the first time all trip in late position and open for the standard raise, with only the small blind calling. The flop of 9h 3c 2c seems perfect and my continuation bet is check-raised by the small blind. He's almost pot-committed so I push in the rest of my chips and he calls.

I have AA; he has KK, he has two cards to hit one of the two remaining kings. The first card off the deck is the King of spades and I am gone.

Obviously, I didn't do anything wrong (and neither did my opponent). It's early enough in the tournament and this kind of thing is so common I actually don't feel too bad, thinking I can get some rest and catch up on things. On my way back to my room I decide it's time for a treat so I book myself a massage and get changed for the gym.
