After the ♥A at trick one South must immediately ruff a heart. The order of play to the next four tricks is not precise (sorry about that!) but must involve two rounds of spades, another heart ruff by South and a lead of the ♦Q. Assuming West wins with the ♦K and returns a diamond, the following ending is reached with South on lead:
A spade to the ♠Q wrings a diamond from West (if a club, then ♣A and another establishes the suit), whereupon ♦J and another diamond throws that player in for a lead away from the ♣K.
