Solution

Declarer wins with the A and immediately finesses the 10, losing to Eastís A.  To create any difficulty East must return a trump honour, taken by Southís A as North pays high to preserve the 2.  A spade is ruffed high and followed by three rounds of clubs, South discarding two diamonds and ruffing the third in case West has kept the 7 and East, who must be kept off lead at this stage, the 8.  The cards now lie like this, with South on lead having lost one trick:

♠ none

 765

 K65

♣ none

♠ QJ

 none

 10987

♣ none

♠ 9

 Q3

 AQ4

♣ none

♠ 54

 765

 J

♣ none

The J is run round to Eastís Q and East must play Q and another heart to prevent the cross-ruff.  North plays high under the Q and West, having already perforce discarded two diamonds, is caught in a ruffing seesaw squeeze (also known as an entry-shifting squeeze).  If West discards a spade, North plays the 2 and ruffs a spade so that Southís diamond ruff and spade winner take the last two tricks.  If West instead discards another diamond, North overtakes and leads the K to set up a trick for the 6 with a spade ruff as entry.

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