Matchpoints. Table Result 7♦*-3 EW+500. Lead A♠
This was a potential Law 23 adjustment from Tuesday's duplicate at a North London Club. Charlie the Chimp was South and opened a Multi and before West could call, the Rabbit, his partner, passed. RR suspected his partner had a weak two in hearts, not spades, and felt that playing in 2♦ was reasonable. The TD was called, and correctly observed that it was a pass of an artiificial call and read out the relevant law (31A). East declined to accept it. West bid 2♠ and RR elected to repeat his pass, and South, ChCh was also forced to pass on his next turn. There was no further rectification and East-West reached their cold spade slam. However, ChCh was not done yet, and guessed that if his partner wanted to pass a multi, 7D rated to be cheap, and so it proved, getting a complete top and even beating the solitary pair whose opponents missed slam.
SB, West, was unhappy. "We need the director". "I think there was a breach of Law 16D, in that information from the repeated pass was UI to South, and this demonstrably suggested the save", he claimed. "But the call was not withdrawn," replied ChCh, "it was cancelled and then repeated". SB tried again: "In that case, we have to fall back on Law 23 in that RR could have known that passing the multi out of rotation could well damage the non-offenders". "RR could not know anything", replied ChCh."And it would have been incredibly far-sighted of anyone to think at that stage there would be a save at the seven level"
