Can you let this go?

Later stages of B&M tournament. Blinds 300/600 with 50 ante. Full table. Big stack in tournament is two places to my right. He's been happily pushing the table around. Two tables away from the money. I have about 23k chips (third at table). He has about 60k.

Big stack raises to 3k from MP3. I'm on the button with KQs. I call hoping to hit a big hand and trap him into doubling me up [img]/images/graemlins/smile.gif[/img]

Flop is K94 rainbow. He checks/I check. Turn is a 7, putting two of a suit not mine on board. He checks, I bet the pot, he pushes me all in.

What the hell do I do? I'm sitting on top of the world slowplaying what I thought was the winner, and he hits me for all my chips. I'm still in OK shape if I fold...
