Tournament Hand Evaluation

Hi all, this is my first post so please go easy on me if I'm not posting in the right place or in the right format.

I played in a NL Hold-em tournament Wednesday night at my local casino and would like some feedback on a hand I played.

In late position with the blinds at 100/200 I'm dealt A [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/club.gif[/img]. UTG calls 200 and everyone else folds to me. I raise to 600 and everyone folds to BB who re-raises to 1200. UTG folds and I call 600. There is 2600 in the pot.

Flop K [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/diamond.gif[/img]Q [img]/images/graemlins/diamond.gif[/img]

BB bets 500.

After some time I said "I believe you want me to call". He said nothing and I folded and showed my hand. The table proceeded to tell me how crazy I was to fold the hand.

My thought was the re-raise could have meant AA, KK, QQ, or AKs. After the flop I didn't think he had KK since I was holding one and there was one on the board. Of the remaining hands I could only hope to chop against the AKs if he didn't hit a flush. Also, the 500 bet was really small in comparison to the pot. I thought it was a trap and he wanted me to call. Was this the correct thought process and did I do the right thing?

Thanks for the feedback...
