This deal was from a duplicate at Bramhall and Cheadle.
The auction, like the final contract, was a thing of no great beauty, however the play was interesting.
West led a diamond to East's ace and a diamond was returned. When declarer played a trump to the king West initially discarded a heart, but then replaced it with a small spade. Declarer (Gilbert Lee) may have thought that West had got a trick ahead of herself and successfully finessed the seven of spades on the second round of trumps. With the 4-1 break revealed he had to shorten his trumps in order to coup East. So, a club to dummy followed by two hearts throwing two diamonds. Then trump the queen of hearts, a diamond to dummy, trump the jack of hearts, then two top clubs and another club forced East to ruff and declarer had the rest. This is a double grand coup, double because you reduce your trump length twice and grand because you are ruffing winners.
