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:
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.
