Partner is awake, but needs steering

Our friend A.N. Onymous said, “Many of us have heard opportunity knocking at our door, but by the timewe unhooked the chain, pushed back the bolt, turned two locks and shut off the burglar alarm— it was gone.”

We have an alarm-clock play in bridge. It isn’t towake partner, because he isn’t asleep; it is to tell him that an unusual play is needed to defeat the contract. Can you spot it in today’s deal? South is in four spades, andWest guesses well to lead the heart king.

In the auction, South’s three-diamond rebidwas a help-suit game-try, indicating a six-loser hand that needed help in diamonds. North, with more than half of his points in diamonds, jumped to four spades. He did wonder about three no-trump, though. If he had bid that, presumably Eastwould have led the heart jack, and the defenders would have taken the first five tricks.

West led the heart king and continued with his second heart. East took that trick and cashed a thirdwinner, onwhichWest discarded the club three.

At this point, East shifted to a club, despite partner’s discouraging discard. Declarerwon, drewtrumps and had10 tricks: five spades, one diamond and four clubs. (RememberWest’s discard at trick three.)

Yes, West’s signal should haveworked, but he had a better play. He should have sounded the alarm by pitching the diamond queen! Thiswould have asked partner to do something unusual— and what is more abnormal than giving declarer a ruff-and-sluff? Notice that a fourth heart promotes a trump trick for West.
