1 - E attempts to bid a insufficient 3H. Director called. He ascertains that E-W have no agreement as to what 3H "would have meant". 3H is not accepted. East is effectively informed that since 4H would be conventional he can bid what he likes but will bar partner. He is also told that, not only can he not double at this time, but specifically that he cannot double at any subsequent opportunity to call. This latter is queried, with E asking to be read the ruling "from the book". The director attempts to do so, but cannot find the relevant passage (!). In any event E corrects to 5D.
2. S confirms with director that "he really can't double?" Director still hasn't found the relevant passage, but encourages play to continue. S bids 5H.
3. E tries to confirm again, but ultimately bids 6D.
4. S doubles, since he isn't barred from doubling. It turns out he may have wished he had been barred, since 6DX rolls. [AH lead ruffed, cross to dummy, small diamond won by the ace, heart ruffed, cross to dummy, small diamond finessed, and W claims].
By the end of the hand, the Director returns and admits his guidance was in error, since the bar on doubling applies only to the current turn to call. S states he wouldn't have bid 5H without the guidance.....
At the other table 5D makes 5, with declarer noting he could have made 6, but had been "too lazy to try."
Director rules under director error, giving a non-reciprocal adjustment, granting NS a score based on 5D making 5, and EW +3imps on the board. If the table result stood, E-W would have gained 12 imps.
EW appeal on the grounds that there is no reason to give a +3IMP artificial adjusted score, since it was possible to achieve a table result. Moreover, since they are to be treated as "non-offending" there is no reason not to give them the table result.
How do you rule?
