Two rulings cropped up during the weekend which I thought of sufficient interest to share with you. In both cases I'll start you off with the first part of the story and when you've had a chance to respond to that, I'll follow-up with what happened next.
It was indeed Board 1 - a hand played during the first match.
I won't give you the hands at this point because I think that as TD you wouldn't have seen them yet.
West alerts East's 2♣ bid and before selecting his opening lead the North player asks the meaning of that bid. He is told "Diamonds"
His card is placed face-down on the table. Now, East says "I think that my partner's explanation is wrong. 2♣ asks about partner's majors".
Quite correctly you are now called by the North player, who says "I've been given misinformation. May I change my opening lead?"
I ask for the information given by East-West and check their convention card. Although they are not a pair well-known to me they have clear and fully completed convention cards. (The Welsh Bridge Union uses the Convention Cards designed by the English Bridge Union) In the "Defence to 1NT" box is clearly written "Transfers". West is clear in his view that this is the correct explanation.
Will you let North change his opening lead?
