Revoke (EBU)

.............♠9 ♥- ♦1087 ♣5
♠76 ♥- ♦AQ9 ♣-
South is declaring a spade contract. The West hand is irrelevant.
South leads a diamond to dummy's jack, and East ruffs with the ♠9. South then faces her hand and claims the rest. The director is called when it comes to light that East has revoked.
How many of the last five tricks does South get?

If East/West do not agree to the claim before the revoke comes to light, the revoke is not established and must be corrected. EBU White Book 70.3 tells us to assess the claim with any doubt going against the revoking side. The defenders will only make ♠9, giving four of the last five tricks to declarer.

Four. East could not fail to take one trick by any means.

If so, then the revoke trick is transferred to South, so South makes the final five tricks.
If not, then the revoke is not established and East must play a diamond. East will now make his master trump and South will make four of the final five tricks.
From the wording of the post it sounds as if the defenders did agree to the claim, but this seems to me to be the critical point for the TD to establish at the table.

Insufficient data. Did either defender agree to the claim "orally or by facing his hand or in any other way"?

i suspect that's actually supposed to be referring to 'making a claim' not 'agrees to a claim' (64A3).
typo: 63A3

Nowhere else in the laws (law 69A in particular) is there any suggestion that a defender exposing his hand in response to a claim signifies acceptance.

Also, even if L63A3 is meant to imply that a defender can agree to a claim by facing his hand, I am not sure that it implies that facing his hand constitutes agreement. Another possible way to agree to the claim is orally, but that does not imply that any oral communication would constitute acceptance of the claim. Surely intent to accept the claim is required, in a similar way to a faced card being a lead if intended as such but not otherwise.

Why interesting? (I really feel I am missing something.)
♦J wins. A ♥ is played from dummy and East must play ♠9, winning the trick. South's remaining three cards are good, whatever he plays on the ♥. Four tricks?

If he says he's contesting the claim, yes. If he just faces his hand without saying anything, he's agreeing to it.

If the revoke was established, declarer wins the last four tricks, and then one trick is transferred to him because of the established revoke. If the revoke was not established, the ♠9 becomes a major penalty card, declarer wins trick 9 in dummy and leads a heart. East ruffs, and declarer must discard a winner from his hand. EW get one of the last five tricks, declarer gets four. So what's interesting is that if either defender contests the claim, the revoke penalty disappears, Law 64C does not apply, and the defenders get one more trick than they would have if the revoke was established.

How did you reach that conclusion? It's certainly not supported by the Laws covering claims and concessions.
The most common reason for a defender to face his hand after a claim is to help his partner to decide whether to accept the claim or not. I can't recall anyone ever accepting a claim by showing their hand - usually one does it by folding one's cards up and putting them back in the board.

I don't think that's quite right. If one defender agrees to the claim but the other contests it, the revoke is established.

OK. I thought you meant the fact that ♠9 would be a major penalty card was important/interesting.

It is an interesting comment you made here, more often seen on rec.games.bridge than here. It is certainly true. But while the lawmakers have said so, that does not mean that anyone should rule on that basis: they rule on what the Law says. It was a comment on how the Laws had changed: the approach of following the Laws remains unchanged.
The most commonly applied and basic penalty still in the Law book is the transfer of tricks after a revoke.
