At the end of the auction South did not call the director and report partner's wrong explanation of their agreement
West led a trump. South won the opening lead, drew two more trumps and led a diamond from dummy. East put up the jack as a suit preference signal for spades. South finessed the queen which lost to the king. West shifted to a club, won in dummy and South called for a diamond, on which East played the ten. South's 9 and 8 of diamonds became good and the slam was made with 5 hearts, 1 spade, 4 diamonds, 2 clubs and a spade ruff in dummy.
East was livid that South showed a diamond singleton in the bidding and produced 4 cards in the suit, causing her to mis-defend.
The TD was called.
The TD ruled that when South played the queen of diamonds he was known to also have the ace, since he had shown two aces. South's diamond could therefore not be a singleton. East should have reasoned accordingly and had no valid reason to play the ten on the second round of the suit. The TD ruled that the damage to E/W was self inflicted and no redress was due.
