South opened One Spade and North raised directly to Four Spades. East ventured Five Hearts and, under pressure, South contested with Five Spades. A sacrifice in Six Hearts was a possibility for West, but he (wisely) decided to pass.
The lead of the four of hearts went to East's ace and he found himself with only one safe exit card - his singleton trump. South won, drew a second round of trumps and followed with a finesse of the 10 of clubs, losing to East's jack. This left East in a difficult position. He reasoned that, as a club return would clearly give away a trick, his choice lay between leading a diamond honour (and hoping that declarer misguessed on the second round of the suit) and conceding a ruff and discard.
In the hope that the latter would not prove fatal, East led a heart. Declarer discarded a diamond from hand and ruffed in dummy. He still had a potential diamond loser, but when he followed with the ace of clubs and a club ruff East's king fell and dummy's queen was established for a second diamond discard.
It is true that declarer might have gone wrong after a switch to a diamond honour, but suppose East had simply returned a club into dummy's tenace? Declarer enjoys one discard on the ace of clubs but is left with an inescapable diamond loser.Reuse content
