You are East. The bidding has been as shown.
Partner led the ♠A, dummy played the ♠2 and you signal with your ♠10.
West next plays the ♠Q and you drop the ♠4, completing your doubleton signal.
West then plays the ♠K and it turns out you don't have to ruff after all.
So what are you going to play?

  Play the ♣9.

This should be a clear enough signal for West to play a ♣ to your ♣A next.

An alternate play, just as good, would be for you to ruff the good ♠Q and play the ♣A yourself.

If you don't get your ♣ trick at trick 4 you will never get it. South will discard his ♣K on North's extra winner.
