A defensive problem from a Cheadle duplicate in January.
You lead the spade six against five hearts, declarer plays the two from dummy, partner the three and declarer the five.
Somewhat to your surprise you are on lead at trick two. What do you play now?
Declarer has a singleton spade and partner knows that. Why has he left you on lead, rather than overtaking and playing a diamond through?
The answer is that he has a void diamond, so play a diamond for partner to trump. You still have the club ace and diamond king to come for two down.
The full deal was
Declarer needed to play the spade king from dummy at trick one to escape for one down.
Well defended by Neil Thomas who found the play of the spade three.
