The match was against the Netherlands, and the Dutch West became declarer in Seven Hearts after a long and complex auction.
The defensive play employed by Nicola on this hand has been documented, but recognising the situation and reproducing it at the table, without any break in the tempo of play, is not so easy.
Nicola, sitting North, led the jack of spades against the grand slam. West won with the ace and played the king of hearts, on which Nicola Smith played the nine. The effect of this was to create a losing option for declarer.
If Nicola had followed small, declarer would have continued with the queen of hearts, catering for North to hold J x x x, and she would have exposed the 4-1 trump break and taken the finesse against the jack.
The play of the nine, with 10 8 sitting in dummy, created a losing option. If the nine is indeed a singleton, then a trump to the ace followed by the ten of hearts will pick up J x x x in the South hand.
Declarer did then play a low trump, and although Nicola followed with the two, she put on dummy's ace and the grand slam was defeated.
