Teams.  Iceland 40 team event, playing for seats in 12 team qualifying.

West is expert+.  East is advanced, North and South are advanced+

2♣ is precision.  When the 2♦ doubled came back to west, he asked about the double, the answer was. - Suggesting a penalty.

Then West bid 2♠, and was doubled again,  6 tricks.  300 N/S.

When the hand was over, North said over the table.   I meant this as a takeout double.  We talked about this yesterday.  A double would be just equal to normal d♦ bid by me.   South had forgot.

West called TD and wanted score adjusted to 2♦ making, If he had had Norh's explaination, he would never have bid 2♠.

I asked 5 expert players about what they would have done when 2♦ were doubled for suggested penalty, and all of them passed.

I asked 2 expert players, often members of appeal committees about adjusting the score.  They did not want to adjust the score.

I ruled.  Table score stands.

-------------------------------------

I made a mistake.  Where it was written,  ""When the 2♦ doubled came back to east,"",  Then I meant West.  It has been corrected
