The opponents win the auction. Declarer checks into your leads,signals and discards before playing to trick one. You have a neatly completed convention card which says something along the lines of 2nd/4th and standard honour leads. It shows that you lead top from doubleton. You also have an agreement that, in the middle of the play, you play low from a doubleton (who knows why!). This is not on your card and your opponent has no reason to suspect it. Declarer had the card in front of her and had clearly studied it both at the start and during the play.There isn't of course an explicit space for this on a standard card but would you as a TD
1. be inclined to the view that this is just tough if she did not ask
2. wag a finger at the offending pair and ask them to put this on their card
3. Adjust if you established that this was their agreement and damage had been caused by the lack of information
4. Something else, please specify

Swiss Teams:

(1) alerted, explanation requested at (2) and given by East as "pre-empt in either minor". (This was a slip of the tongue, he had meant to say "major" which was the true agreement, and didn't realise he had misspoken.)
(3) pass or correct

Result: 4 (W) -1, NS +50

I don't know if a correction was offered at the end of the auction as I wasn't the TD called to the table, but North claimed afterwards that she would have overcalled 4 given the correct agreement.

What sort of adjustment, if any, would you consider?
