Solution

This one is heavily based on a hand played by the composer in October 2018.

North wins the opening lead with the K and cashes the K.  A low club to the 9 and J forces a spade discard from East.  West must return a low heart—anything else would give declarer the ninth trick—and this runs to East’s Q and South’s K.  South now cashes the top spades, on which North discards diamonds, squeezing West in this ending:

♠ none

 A

 J1098

♣ 83

♠ none

 J98

 Q5

♣ A7

♠ 108

 65

 K43

♣ none

♠ J3

 1043

 A2

♣ none

A.      If West discards a diamond on the J, North discards a club and then the A and another diamond give declarer an overtrick.

B.      If West discards the 7, North discards a diamond and South plays the A and another diamond.

1.       If West wins with the Q and cashes the A, North's red suit tops win two more tricks.

2.       If West wins with the Q and leads a heart, North wins and exits with a club to the A and South gets a trick with the 10.

3.       If East wins with the K, North will get two more tricks in the red suits.

C.      If West discards a low heart, North is accessed with the A and a diamond is run round to West’s Q.  However West now plays declarer will score a trick with either the 10 or the 8.  If West cashes the J, North discards a diamond to keep the 8 guarded; otherwise South wins the diamond return and puts West back in with a heart.

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