Solution

North plays high on the opening lead, and East does best to return a club.  South wins with the A, plays a spade to the K, ruffs a diamond, and exits on a second spade to East (South’s 10 prevents West from taking this trick).  North ruffs high the club return and South ruffs another diamond.  The 10, ruffed high by North, gives following position with North on lead:

♠ none

 K8

 J54

♣ none

♠ A987

 6

 none

♣ none

♠ none

 1098

♣ KQ

♠ none

 95

 none

♣ 1043

North leads the 8 to catch East in a criss-cross ruffing squeeze, South overtaking if and only if East discards a club.

Play can follow similar lines on a diamond return at trick two but then declarer has an alternative: ruff, cash the A, ruff a club with the 8, diamond ruff, spade to the K, diamond ruff, club ruff, low diamond ruffed with the 9, club ruff, K drawing West's last trump and the good J is the eleventh trick.

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