a ) At the Woodenhead Christmas Social I reached 6NT by South. At the social an extra rule comes into play after the auction. It might be “the opening lead will be made at random”, or “dummy plays its own cards without prompting”. A slip indicates the rule. This time it was that “the partner of a person who wins a trick will lead to the next one”. West led the queen of clubs and East played the seven. How did I make my contract; and what were the E/W hands?
b ) Lo and behold, a few days later, at the Buttons Xmas Social (another special slip event) my partner and I picked up these identical hands, and again we reached 6NT by South! This time I was disappointed to find that the “special slip” indicated that aces had become low and twos had become high, so that all cards were in reverse rank, but I still managed to make my contract. Again West led the queen of clubs and East played the seven. How should I play and what exact layout do I need?
"Curious hand", observed my friend the Owl. "6NT cannot be made without the special rules."
