Some proposed a lower DR but I was impressed by the fact that a few solvers went wrong on this one.

Solution

North wins the first trick with the ♠A, and leads the Q, won by Westís K.  West switches to the 10.  North and East play low.  South wins with the K, and leads a low spade to the ♠J.

A.      East wins and plays:

1.       the A and the J which runs to Northís Q.  Declarer can now play on straightforward lines, cashing the ♣A, finessing a diamond, and just giving up a club to West.

2.       a spade to the ♠Q.  South leads a low club to Northís ♣10 and Eastís ♣K.  East exits with, say, a low diamond, but declarer can make two diamonds, the last spade, and three more clubs by leading a high club from South.

3.       the ♣K.  This is allowed to hold the trick.  Play then reverts to line 2.

B.      East ducks.  North leads the ♣J to Eastís ♣K.  To remove Southís entry before the long spade is established, East exits with the J, won by Southís A.  South leads a high club, which holds the trick, and then takes a club finesse, cashes the 10 (and, optionally, the last club), and throws East in with a spade, forcing a lead to the Q.

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