Successful solvers: Steve Bloom, Ian Budden, A.V. Ramana Rao, Andries van der Vegt.  Suggested DRs ranged from 4 to 8 but as several expert solvers got this one wrong I've gone for a high rating.  I think these four deserve a Start Point each.  Tables

Solution

At trick two South leads the K!  East does best to win this trick and return the K to North’s A.  South comes to hand on the second club and leads a low heart.  West does best to win with the K and play another heart to North’s Q.  North leads a club and East does best to discard a spade.  South ruffs and leads a spade.  West does best to duck but North ruffs anyway!  Here is the position now, with North on lead and declarer needing four more tricks:

♣ none

South ruffs a club, cashes the A on which North discards a diamond, and leads the J.  If East wins, North makes the last two tricks with the 7 and 6; otherwise, the J10 give declarer one of the last two tricks.

Variations:

A.      If West, on making the K, returns a diamond instead of a heart, South can ruff the third diamond with the 8 and then play spades until West covers.  North ruffs and cashes the Q and South can make the last three tricks with a ruff, the A and a good spade.

B.      If East returns a trump at trick three, South plays low.  West wins with the K and leads another heart to North’s Q.  South comes to hand on a club and plays spades until West covers.  West does best to duck two spades, in which case North discards diamonds.  South can now lead a third spade, North discarding a third diamond!  West returns a club, ruffed by South.  Then come a diamond to the A, a club ruff, a diamond ruff, and the A wins the last trick.
