($11 Pacific) Fold KK pre-flop?

It's like the 4th hand of the STT. Somehow I've managed to loose t100. That's not the point here. I'm in the BB, with KK. It's folded to Button who makes it t40. SB calls, I raise to t150. Button (has me covered) moves all-in. SB calls. Hero??

Is this one of the rare cases I should fold, or do I press Call and close my eyes?
