Solution

Declarer plays the 4 from dummy and wins in hand with the K, cashes the K, and leads the J, followed by a second heart if West ducks.  When North gets the lead on the K the A is cashed, South discarding a spade, and South ruffs a club.  The remaining trumps are drawn.

A.      If Eastís last club is the 5, North wins a diamond and loses a club to West, South discarding a spade.  West then has to lead into Southís AQ.

B.      If Eastís last club is an honour, then South cashes the last heart in this ending:

♠ 43

 none

 AQ8

♣ 4

♠ K1087

 none

 9

♣ 9

♠ J9

 none

 J76

♣ Q

♠ AQ6

 3

 32

♣ none

North discards a spade on the 3.  East cannot let go a diamond.

1.       If East discards a spade, declarer cashes the A, plays a diamond to North, and throws East in on the club for a diamond lead into A8.

2.       If East discards a club, then Northís diamond winners are followed by a club to West and South makes the AQ.

Trap: If South makes the mistake of cashing the last heart in line A, then West discards a diamond, East a spade.  When declarer then crosses to North in diamonds, West jettisons the club winner to avoid the throw-in.  This defence is an example of the delayed jettison, a favourite theme of double dummyís most prolific composer, Ernest Pawle.
