KQ in SB against raise from button

[A_K]

[ QUOTE ]
SSHE suggests to fold this but since the raise comes from the button I'm a little unsure.

SSHE is not talking about acting after an open-raise from the button. I would certainly not fold. As others have said, either 3-bet and lead the flop or call check-raise the flop. You are way ahead of an average (unknown) villain's range here.
