Solution

The 9 lead goes to the 4, 5, and A.  South leads the 2, North playing low.

If West wins, declarer has the tempo to ruff a diamond in dummy.  On regaining the lead declarer gives up a diamond to East and will then take the diamond ruff.  Declarerís remaining trumps will be big enough to restrict East to one spade trick.

To prevent the diamond ruff East wins the second trick, overtaking the 9 with the 10, and leads the ♠K.  South wins and leads a diamond, won by East, who continues with the ♠Q and another spade to the ♠J.  South enters hand with the ♣A, and draws Eastís last trump, discarding a club from North.  West comes down to three clubs, a heart and a diamond to give this position:

♠ none

 A4

 none

♣ Q65

♠ none

 K

 8

♣ J109

♠ none

 765

 KQ

♣ none

♠ 84

 8

 3

♣ 2

South plays another spade and West is squeezed in three suits

A.      If West discards a heart, North discards a club.  Declarer then makes the8, ♣Q, A, and the last trump.

B.      If West discards a club, North discards a heart.  Declarer then takes the ♣Q, ruffs a club, and enters North with the A to cash the long club.

C.      If West discards his last diamond, North discards a club.  Declarer then takes the ♣Q and ruffs a club, squeezing East in the red suits.

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