KK early in Live MTT

[docknet]

I know that some of you will tell me to stop whining about this bad beat, but my question is simple--would any of you played this differently?

Early in a live MTT, I woke up to KK in SB. Everybody has about the same amount of chips: $5000; blinds are 50/100, first level.

Two or three players before me and the BB limp in, I raise to $300, and BB raises to $500. Everybody else folds. I call.

Flop is:

2c Kh 3d

I check, BB bets $300, I call.

Turn is 4s

Now I see that there is a possible hand building out there, so I bet 500, BB raises to 1500.

Here is my thought process: The BB, a young guy barley old enough to be in the casino, is shaking and visibly excited about his hand. However, this was also the case preflop and postflop. I had him on AA, AK, QQ or JJ, but I really hadn't been sitting there long enough to have a good read.

Anyway, calling would take half my chips. Besides, I was SURE I had the best hand. So, I pushed allin.

He sat there shaking for a long time, and then finally called, turning over AKo.

My chances were better than 90/10 to win this hand. He had four outs. My tournament ended early.

My only other two options were to call, which seemed silly, or reraise, which also seemed futile, because I was sure he would call. (folding did not enter my mind) Besides, I was positive I would have all of his chips in a minute or two.

Seemed right to me, except for perhaps making the flop a lot more expensive, or perhaps not slowplaying on the flop, but I knew by his reaction upon his winning the hand that he was not even aware of gutshot draw.

What do you think?
