If, after the commencement of the auction period, the Director discovers that a contestant is playing a board not designated
for him to play in the current round, then:
- if one or more players at the table have previously played the board, with the correct opponents or otherwise, the board is cancelled
for both his side and his opponents.
- if none of the four players have previously played the board the Director shall require the auction and play to be completed. He allows
the score to stand and may require both pairs to play the correct board against one another later.
- The Director shall award an artificial adjusted score [see Law 12C2(a)] to any contestant
deprived of the opportunity to earn a valid score.
