The Rabbit, East, had been trying out his new toy of opening 2NT to show both minors 7-11 and did so on the above hand at a North London Club last night, but ChCh, South, quickly pointed out that RR was not dealer. The TD came and gave South the chance to accept it, which he declined, and ChCh opened a 15-17 NT and North raised to 3NT. "Before you lead, SB", Oscar the Owl chipped in, "South can require the lead of any one suit not specified in the legal auction OR prohibit the lead of any one suit not specified in the legal auction."
"That is fine. I think I will require a spade lead, please," ChCh smirked. "He who laughs last laughs longest," replied SB, "and I think Oscar's sobriquet of "Owl" is misplaced on this occasion." "Ostrich might be more appropriate. Did not everyone read the ridiculous memo from the WBFLC which arrived yesterday, indicating that 26B1 had been deleted and this was with immediate effect?" "The declarer can only prohibit the lead of one suit now, he cannot require a specific lead."
The Owl warned SB that his abrasive manner was close to getting a DP but was forced to agree that the Chimp could now only prevent the lead of one suit. Not unnaturally he elected to prohibit a club lead but SB selected the lead of the nine of diamonds and declarer could no longer succeed; RR ducked the first round of hearts ridiculously but this did not help the Chimp. Every other declarer had made 10 tricks on a spade lead, so this was a complete bottom for NS. The Chimp was not that happy. "Did not SB take advantage of the opening 2NT which was withdrawn which was UI?", he asked.
"Can I answer for the hapless Owl, please," responded SB. "Subject to Law 16C2, after rectification of an infraction it is appropriate for the offenders to make any call or play advantageous to their side, even though they thereby appear to profit through their own infraction (but see Laws 27 and 72C). Law 27 only concerns itself with insufficient bids - so an adjustment would have been appropriate if RR had bid 2NT over 3NT instead of his BOOT. There is no question that RR could have been aware of possible damage, so Law 72C does not apply. He was not even aware who was dealer! And the diamond lead was marked with a weak hand and no entry for the spades. In addition, the Chimp required a spade lead which he was not allowed to do, and that is AI to me. Finally the nine of diamonds was far from demonstrably suggested, given that NS are known to have seven diamonds from the UI. And it certainly is not suggested over the club lead which does use the UI"
How do you rule?
