Hi

I am often consulted about rulings from major Scottish events but I did not know what the ruling should be in the following case. I cannot publish the precise hand and happenings because too many people are embarrassed by their play, their failure to call the director in a timely manner, their inability to remember what was played when, and the director is not happy either with their own performance, but I think I can provide the problem I was unclear about.

Declarer was following the normal line for the contract and heading for down two. Late in the hand a defender revoked, not winning the revoke trick, but this caused declarer to go four down as his long suit could no longer be run. The one-trick revoke penalty would not restore equity, so the director should do so.

Is equity two down, as would have happened without the revoke, or one down given the normal result following a one trick revoke penalty?

Part of the embarrassment is that if declarer had called the director before the revoke was established, the bizarre card played as the revoke would have been a penalty card which could have led to the contract making. Declarer's initial argument to the director was that this should have been the ruling :)

Thanks for your assistance

You seem clear that without the revoke declarer would have gone two down, so that is what it should be adjusted to. In cases when the outcome is less clear, a weighted result might be awarded.

I think the basis of an equity ruling must be what would have happened without the infraction, not what would have happened if the infraction had been pointed out earlier.

I agree with declarer: Law 62.B.1

My ruling would be director error IF called before the revoke was established.

Equity is two-down.

If declarer had called the director before the revoke was established (provided of course that he was aware of the revoke already at that time) he would be entitled to the favor from the effects of the resulting major penalty card. This favor was forfeited by not calling the director!

I find it the best way to resolve this by following the Laws. There was a revoke, and it became established. Law 64C1: “When, after any established revoke, including those not subject to trick adjustment, the Director deems that the non‐offending side is insufficiently compensated by this Law for the damage caused, he shall assign an adjusted score”. Now we turn to Law 12C1b: “The Director in awarding an assigned adjusted score should seek to recover as nearly as possible the probable outcome of the board had the infraction not occurred”. You wrote that without the revoke the result would have been-2, so that would be the AS.

There's no requirement to call the director before the revoke is established. You only have to call the TD once someone calls attention to an irregularity, and players are not required to call attention to their own irregularities.

And in general, it's rarely to declarer's benefit to call attention to the revoke before it's established. The normal revoke penalty will give them an extra trick. And if ththat doesn't restore equity, the TD is required to adjust. So the only way calling the TD before the revoke is established can gain is if you can do better than equity+1 by taking advantage of the penalty card from the non-established revoke, and that's pretty unlikely.

The case quoted proves to be an exception.

NB The requirements for correcting an unestablished revoke changed in the 2017 laws.

LAW 62 - CORRECTION OF A REVOKE - 2007 version
A. Revoke Must Be Corrected
A player must correct his revoke if he becomes aware of the irregularity before it becomes
established.

LAW 62 - CORRECTION OF A REVOKE - 2017 Version
A. Revoke Must Be Corrected
A player must correct his revoke if attention is drawn to the irregularity before it becomes
established.
No matter how well you know the laws, there is always something that you'll forget. That is why we have a book.
Get the facts. No matter what people say, get the facts from both sides BEFORE you make a ruling or leave the table.
Remember - just because a TD is called for one possible infraction, it does not mean that there are no others.
In a judgement case - always refer to other TDs and discuss the situation until they agree your decision is correct.
The hardest rulings are inevitably as a result of failure of being called at the correct time. ALWAYS penalize both sides if this happens.

You proceed too fast by going directly to Law 64C1!
Before trying Law 64C the Director shall always first try Laws 64A and 64B.

That doesn’t matter much, does it? There’s no automatic adjustment, but I thought that was clear from the OP. But there certainly was damage to the NOS, so it’s a 64C case. That law doesn’t carry a time limit, and therefore the TD has to adjust.

First there was a Law 64A automatic one trick adjustment and then Law 64C is tried.

With this in mind there should be no doubt (as indicated by OP) about what constitutes equity.

yes - 2-down.

Declarer goes 4-down. We give him a trick. He is now 3 down. (64A)

Declarer determines that this is inadequate compensation and so awards an adjusted score. (64C). You don't give an adjusted score and then add the revoke penalty.

Precisely.

I suspect that what confused OP was the fact that if the revoke had been discovered before it was established and then if the Director had been called then play would have been continued with the major penalty card, probably(?) resulting in declarer making his contract.

This is quite true, but is completely irrelevant as the director was not called at that time.

I feel sure that such a situation occurred at a North London club; I will have to consult my files.

Could declarer have figured that out at the time the revoke occurred, so he'd know that he's better off calling attention to the revoke?

A benefit for some of us is not winning an automatic unearned extra trick. This is one reason I love online bridge, impossible for my opponents to mistakenly, or otherwise, revoke.

I can't find it now, but I thought there's a Law requiring you to try to take the maximum number of tricks legally possible. This means you shouldn't refuse to take advantage of a revoke penalty because you think you didn't "earn" it.

Quote

Law 10C3: When these Laws provide the innocent side with an option after an irregularity committed by an opponent, it is appropriate to select the most advantageous action.

This doesn't make it a requirement, it just says it's not unethical to do it.

Barry may be thinking of this regulation:
