Almost as if by syncronicity, this deal showed up at the ongoing US trials for Shanghai.
Auction (Stansby-Rosenberg) was 1C-1S; 1NT (weak) - 3NT. What would you lead from:
Even with a thorough comprehension of canapé leads, it would be hard to not lead a diamond at the table. Teammates might be less than forgiving if a club is wrong.
Nerves of steel would have gotten you the prize as the canapé lead, once again, was the trick winning move.
The diamond lead gives away a trick and the contract immediately. After a club lead, declarer can still make it but may go down by finessing in diamonds at some point. The long suit lead also gives away information which helps declarer with the heart position, info which would be lacking after a club lead. We'll never know if Stanby would've had made it (given the chance) as the actual West led a diamond.
And another deal went to the evidence room.
Thanks to 'free' for reporting the deal; I haven't gotten around to the USBF deals just yet.
