Solution

South wins with the A, cashes the Q, and leads the J.  West must cover to prevent an easy throw-in on East—East makes two tricks in the minor suits but then leads away from the 10 into North’s Q8.  So North’s A wins trick 3 and is followed by a top club on which South discards the potentially blocking 9.  Three rounds of diamonds now put East on play in this position:

♠ Q84

 none

 5

♣ A10

♠ 5

 QJ10

 none

♣ 65

♠ 10763

 none

 none

♣ J9

♠ none

 76543

 9

♣ none

A.      If East leads a spade, North wins two spade tricks and the 5, South having discarded the 9.  East, now down to a spade winner and J9, is thrown in on the spade.

B.      If East leads a club, North wins two club tricks and the 5, South again having discarded the 9.  If East throws the 3 North exits in the 4.  So East throws a middle spade, but North exits on the 8, pinning the 5.  East wins with the 10 but has to lead away from ♠63 into ♠Q4.

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