Dummy "Revoke"

Recommended Posts

Club game - poor standard (obviously).

Declarer in a heart contract ruffs the opening spade lead in dummy which is apparently void. Calls for Diamond ace at trick two and when moving that card dummy discovers a small spade hidden behind the diamonds. What (if any) adjustment applies?

In general, if dummy fails to display all 13 cards and this damages the defenders then we can restore equity through Law 12A. (Failure to display dummy is a violation for which the laws do not provide indemnity.)

 

In this case, the revoke is established because dummy has played to the next trick. There is no penalty (Law 64B3) but the director shall assign an adjusted score (Law 64C).

 

It could be argued that if the A had not reached the played position when the was revealed then dummy had not played to the next trick. Then the revoke is corrected: the spade is played to trick one (the heart is restore to dummy); RHO can change his card played at trick one; and, if RHO changes, declarer can change his card. This may be a "better" solution, but if RHO changes his card then declarer has UI from sight of the original card.

The revoke is established by the lead of the A (Law 63A). There is no rectification for this revoke (Law 64B3), however the director must consider whether the revoke damaged the defenders, and if so award an adjusted score (Law 64C, Law 12).

Do the defenders not have some responsibility for the failure to notice only 12 cards visible in dummy? Would this be a factor in deciding an adjusted score? Might you give the two sides different scores - declarer's side only adjusted?
