Butler IMPs. Table result, either EW +720 or EW +2000 depending how you rule.
This hand caused some acrimony at a North London club this week. As soon as West doubled 1NT, North appeared to go a bright red, but South, who looks and behaves like the Secretary Bird, immediately blurted out "I did not intend to open 1NT". "I intended to pass, and for some reason my hand selected the 1NT card." There was a "turning away of the mind" and "the action did not occur as a conscious process of the mind". The TD was called, and SB wanted to change his call to pass, quoting the WBFLC minute in full, which allowed him to change an inadvertent call before his partner had called. He explained to the TD that he had been thinking how bad a 12 count this was for a weak NT, when, inexplicably, his hand selected that bid. How do you rule?
Although not relevant, at 9 of the other 11 tables, where South opened a weak NT, he went for 2000 on the jack of spades lead.
