N leads ♠7, via ♠K for declarer's ace, who plays the queen and the 6, ♦3 in E and ♦K from S. Declarer turns to S, says he wants to speak with her about this action later on. N interferes and then the declarer asks S what 2♠ means if it isn't natural. She answers 'strong". Next the declarer asks N wether it can be a doubleton and tells him that he should have alerted the bid. Then, and not before, he calls the playing director, who seems to have heard him, but doesn't come to the table. Now the initiative moves to N who states that everybody knows how things are, that they should play on and the director would come later. The declarer agrees and after the play the director is told about the 2♠ bid, but not about the revoke. He decides that the result stands (4♦x -1). Only much later W realises that the director is not told about the revoke. He now wants the result corrected. What should be the decision?
If the director heard but didn't answer the call, I would decide it's a director's error, and treat both sides as non offending. In that case, would you give EW 4♦x made? If the director had come, the revoke would have been corrected, so W would only have lost two clubs and a heart. Or would you change it to 4♦x +1, since the offending side has played in the next trick. Can EW keep their score, or would you change that too? Would it also be a director's error if he didn't investigate properly? Those questions about the 2♠ bid could (or should?) have made him aware that there was something strange about it.
