Table result 6♥= Lead K♦
SB played a match today in the North London teams knockout, which had recently adopted the new Blue Book. In his room, with SB South, the auction went 1S-All Pass, scoring +230, with East judging well not to bid because of his singleton heart. When he scored up, SB was keen to find out exactly what was explained for 2C in the other room on the auction shown, and North, Timothy the Toucan, stated it was "artificial and strong, not necessarily having 16 HCP or 12 HCP with 5 controls, but if it doesn't have that it will have game in his own hand, either in a suit or no-trumps".
"I suspected as much", said SB, "while the disclosure by North was indeed fulsome, the failure to guarantee either 16 HCP or 12 HCP with 5 controls makes it an illegal agreement. They could have played two multis, but they chose not to do so." "OSCAR!", he bellowed at OO. "Can you scrap this board please and fine the miscreants 3 IMPs?" "And I think that means we win the match by 2 instead of losing it by 16, I believe".
How do you rule?
