South put up the ace to continue with the six of diamonds on which East discarded a spade. He could pick up the trump suit with two finesses but was short an entry to take a club finesse and the contract drifted down one, N-S -50.
The grand slam would be a lock as long as diamonds did not break 4-0. South draws trump and parks a club from hand on the fourth heart to score a satisfying +1440. North went through the motions of asking for controls despite owning all five. His continuation of five hearts asked if partner owned the queen of diamonds. The five spade reply promised the queen in addition to the king of spades. South would advance to six diamonds when he did not hold the diamond queen. North judged to venture a grand slam reasoning that partner could dispose of any club losers on the heart winners. The contract was an excellent one but the foul trump division had sealed declarer's fate.
6NT is icy since North can pick up the diamonds without loss and there is a chance of thirteen tricks. East might choose the ten of clubs as an opening shot, handing North an overtrick.
