I would win the king and lead a club to the 9. Assume this loses and the defense returns a heart. Win in hand and lead a diamond to the K. If this loses and the defense returns a third heart, we can win and finesse the SQ, then take the second club finesse. That works if the clubs are no worse than 4-2 with at least one honor onside and either the SK or DA onside.
Unfortunately if the C9 wins I will have no idea how to continue.
