to play the clubs or hearts from her hand, so she must attack diamonds. West wins the first diamond, and returns a diamond, reaching this position:
South is stuck in his hand, and East must score another trick.

the ♠ Q
to take the heart finesse. So say East leads a diamond to West's ace, and West continues a diamond.
