"What do you make of these two travellers, Watson?", asked Holmes, arriving after a duplicate at The Menagerie Bridge Club, which was using 221b Baker Street, the home of the Baker Street Bridge Club, while its normal premises at Regents Park Zoo were being refurbished.
"Very strange", replied Watson. "All but one of the tables played both boards in 4S, except table 1 which played both boards in 7♠x, once with East-West doubled and minus 2, the other this one in 7♠x making".
"Indeed, but did you not notice that when EW was in 7♠x, they were the Secretary Bird playing with Vera the Vixen, and when NS were in 7♠x it was Charlie the Chimp playing with the Rueful Rabbit"?
"Good gracious," replied Watson, "How did you deduce that". "Well, I can see that there is an appeal going on, so Oscar the Owl must have ruled on a board, and only SB ever appeals." He continued: "And 7♠ doubled making smacks of some unauthorised information from another source, so it is my guess that Oscar the Owl ruled on this board, and SB is now appealing."
"What was the previous board?" asked Watson. "Quite interesting, and quite odd", replied Holmes. "I have the board here. I suspect SB opened 4S on ♠QJT9xxxx ♥x ♦QJT ♣x and later played in 7♠x opposite ♠xxx ♥ AKQx ♦x ♣AKQJx."
"Looks like they had a mix-up over Blackwood to me?" asked Watson. "Well, yes and no, I heard SB berating Vera the Vixen in the bar for 'not bidding 5♠' on one board, when he would have passed". It seems clear that VV used 4NT and over the response of 5♣, she assumed that her partner had 3 key cards and went to grand." He continued, "Trumps, I see, were 1-1 but she was still 2 off, doubled. However I am suspicious. Vera the Vixen is far too good a player not to know that she could bid 5S and SB would go on with three key cards. I think she overheard from the other table that 7♠ was cold, but the other table must have played the two boards in the wrong order, as sometimes happens, and what she overheard was from the wrong board."
"Why do you think that?" asked Watson. "Well it was clear that ChCh and RR had been roved out on the previous round, as it was a 13 and a half table Mitchell," so they would have gone to the bar and not been able to overhear the previous round, so they are in the clear. So only VV and SB could have overheard. Now SB is a nasty piece of work, but scrupulously honest and ethical, and he would have called the TD if he had heard. Therefore Vera the Vixen, with the excellent hearing of a fox, the ethics and grooming of a skunk, and a similar level of cunning, assumed they could make 7S and that SB had AK, A for his vulnerable 4 level pre-empt."
"But how does this affect the other board, the one we are looking at here?" asked Watson. "Well ChCh, South, is one of the most unethical players at the club, and the result on the previous board was not lost upon him." "When RR bid 4C, which might well have been Gerber, he KNEW that this was the board that Vera had overheard from the other table, not the other one." He backed his judgement and bid 7S and he was doubled by East."
"Is it possible to make it; it looks a hopeless contract?" asked Watson. "Yes, of course," said Holmes, "with a bit of care and a bit of logic once you know it is making". "There was no trump lead, and West's vulnerable 2NT overcall (showing 5+-5+ in the minors) and the lead, entered here on the Bridgemate as the jack of hearts, makes the hand almost an open book, once you know it can be made." "No doubt when the contract made, SB hit the roof, but as far as I can see from the Laws ChCh is quite entitled to use the information from the previous board that Vera the Vixen had probably overheard something and probably used that information. I heard a loud argument between OO and SB on the subject."
Also, I was polled by Stuart the Stoat, TD from the nearby London Zoo, who asked what I would bid after 1S-(2NT*)-4C-(P) on the South hand. I replied 4♠ of course". He asked, "Would you seriously consider 7♠?" "I will let you work out my reply."
So a two-part puzzle:
a) What layout allowed ChCh to make 7♠x?
b) How do you rule when 7♠x makes?
Thank your for the difficult problem, Lamford.
Assuming West is 5+5+ in the minors, I haven't worked out how South can make 7♠
-- Unless West leads 4th highest or
-- East has AK of a minor
