Solution

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:

 ♠ Q ♥ none ♦ J4 ♣ 432 ♠ none ♥ none ♦ 1098 ♣ K87 ♠ 4 ♥ K8 ♦ none ♣ J109 ♠ 98 ♥ none ♦ none ♣ AQ65

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.

See the solution to Competition Problem #4 for the recommended tabular format if you prefer not to write in English prose.
