East was declarer in 3NT. The diamonds were AKJ8xx in dummy opposite a singleton in declarer's hand. North had Qx in diamonds. The director was called to the table after trick 10. This was the position he saw at the table, with declarer having already taken 10 tricks and the lead in dummy:
Note that North had not yet discarded to trick 10. The director was summoned by NS and told that East had faced his hand without any explanation. East later stated that he was claiming the rest of the tricks. Upon realising that one defender held QJx in ♥, he tried to change it to 12 tricks.
The director considered this and decided eventually to adjust the table result to 3NT+1, as declarer had made no mention of the losing diamond in dummy hence it was possible for declarer to take the careless and inferior line of playing the diamond from dummy first, whereby South would make the rest of the tricks. North South also pointed out that dummy had earlier pointed to North's Q♦ when it fell. Dummy was given a warning for making a gesture which might be suggesting a line of play to declarer.
East decided to appeal. The appeals committee heard from East that when he faced his hand, his partner (dummy) had tried to claim all the tricks for him and he had not been given a chance to state his claim. The committee also considered the play of the diamonds and were sufficiently convinced that declarer knew that the diamond in dummy was not good, hence the result was adjusted to 3NT+3.
Any thoughts and comments regarding the director's and AC's ruling?
