Solution

West must lead the Q!

A.      If South takes this with the K, the best try is to lead a club, which West must cover.  When North ducks this trick, West leads the 3.  East makes two heart tricks, finessing, and exits on a club.  North does best to win and lead a low spade, but East lets it ride and covers the next one, forcing South’s A.  South leads a high spade to North’s Q but East wins and returns a club, ruffed by South.  Even though North can now get the lead in spades South has no way of scoring a trick with the K, thanks to East’s long club.

B.      If South ducks, West must continue hearts and East must play low!  Again declarer’s best chance is to give up a club trick, but this time East wins it to cash the A.  Play now reverts to line A as East exits on a club.

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