Solution

Declarer wins in hand with the A, cashes the A, then leads the Q, covered by the K and A.  North leads the 10, which East does best to duck.  South unblocks the 8 so that North remains on lead when East then ducks the 7.  South now ruffs a heart, cashes the A and J, then exits to East on the third club, giving this four card ending with East on lead:

♠ 7

 Q7

 K

♣ none

♠ none

 J10

 J10

♣ none

♠ none

 K6

 none

♣ 109

♠ Q

 none

 543

♣ none

A heart lead gives declarer a heart trick.  A club lead is ruffed by North, squeezing West: a diamond discard is followed by the K, a heart ruff and a good diamond, whereas a heart discard lets North establish the 7 by leading the Q, with the K for re-entry.

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