Solution

South plays the K and 9, North discarding the 7 and 8!  East does best to win and return a spade into South’s 64 tenace, and now North discards the J.  South now leads a heart.  West must play low—otherwise North can make two heart tricks—so North does likewise.  Winning with the 10, East exits with the fourth spade to leave this position, with South on lead and needing the rest but one:

♠ none

 K8

 K1093

♣ none

♠ none

 4

 A62

♣ none

South leads the 6, rectifying the count for a squeeze on West in hearts and clubs when the A wins the next trick.

Traps:  If North discards the 5 at any time, then East will return a low diamond instead of the fourth spade.  If South allows this to run to North’s J, the North loses a hear and a club while South’s A fails to score. If instead South rises with the A, then the count isn’t right for the squeeze on West.

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