in the firt case NS make normally 3 tricks, but since there is a revoke they end up getting only 2.

on the second one, EW normally make 4 tricks, due to the revoke they make 5, but later 1 is transfered so only 4, no difference, no penalty in the end.

Why are the cases different?

Why are they different? Because the situations are different. We have a Law that in effect simplifies life for TDs - especially lesser TDs - by often making sure equity is satisfied, and also providing a random penalty element of between 0 and 2 tricks. If you do not like the Law this is not the right forum to discuss a change. But we have to interpret it and apply it, and the random penalty element is part of it.

I should go on record here as saying that I agree with almost every word uttered by my learned brother Bluejak.

I would, however, make one small correction: in the phrase "by often making sure equity is satisfied", the word "often" should be replaced by the words "almost never".

Are you seriously telling me that when a normal revoke occurs, one trick does not usually restore equity?

I am not quite sure what you mean by "a normal revoke". What I tell you is this: that the "random" transfer of anywhere between 0 and 2 tricks certainly does not "restore equity" in the vast majority of cases. This is to be expected, of course, for any "random" penalty will have little to do with "equity" in the first place.

It may be worthwhile to examine why the revoke Law and other Laws are as they are.

One begins with the reasonable notion that if you steal what is not yours, you should give it back. One supplements this with the equally reasonable notion that you should be punished for attempted theft. Hence, the earliest form of the revoke law involved an implacable transfer of two tricks - the one that you stole (by ruffing when you could follow suit) and the one that constituted your debt to society as embodied by your present opponents.

The assumption underlying all this is that no one would actually revoke except for immediate gain - that is, miscreants would cheat by ruffing when they could follow suit. Similarly, the assumption underlying the Laws relating to calls out of turn, or insufficient bids, is that no one would actually make them except for gain; so, the Laws were constructed to ensure that [a] no gain could ensue and [b] the offenders would be punished (by having to bid in the dark).

Now, there was no question of "equity" involved in any of this. The notions were more primitive: the penalty for doing wrong combined an element of restitution with an element of deterrence (you gave the opponents their trick back, and you were penalized another trick to encourage you not to commit the same offence again).

Of course, this would not do - it became clear (if it was not clear already) that even after the prescribed penalty was paid, some revokes could gain more than the trick transferred by way of restitution and the trick transferred by way of deterrence.

What was done about this? Well, by that time an enlightened society had chosen to distinguish between deliberate and inadvertent transgressions; so that if you swindled the opponents out of three tricks (with or without meaning to), you didn't have to give them anything by way of a deterrent in order to prevent you from trying the same swindle again. If on the other hand you swindled them out of no tricks at all (as by showing out, then showing back in again while an opponent ran a solid suit), you were punished to the full extent of the Law. That extent is now one trick rather than the two it used to be, but whatever else it is, it is not "equitable".

This is, of course, hopeless. But it is the Law, and (as with many of the other Laws to which I have alluded), it is an unacceptable compromise between one of two equally tenable positions. The first (and the easier) of these is to cast the Laws as if everyone were potentially a cheat. The second (and the more difficult) is to cast the Laws as if everyone were determined to follow them to the letter, and to ignore transgressions by calling them all "irregularities" rather than "infractions", and to refer to "rectification" rather than "penalty". Moreover, one refers - as Bluejak refers in his more lucid moments - not to a "cheat" but, pardon him, to someone who has "inadvertently" failed to follow the rules.

Almost all games have rules that follow the first of the paths outlined above. Bridge is the only game I know that follows the second. Hinc, as someone wisely remarked, illae lacrimae.

On a point of facts: The earliest form of the revoke law AFAIK ordered the transfer of three tricks!

Then it once happened that a player deliberately revoked in a 3NT contract in order to promote a stopper (for instance did not play his stiff K under opponents' Ace), made his 12 tricks, gave away the three penalty tricks and made his contract.

On being questioned Ely Culbertson confirmed that this was indeed the law.

Subsequently the laws were amended to include the equivalent of todays Law 64C and at the same time reducing the "standard" penalty for a revoke to two tricks (which again later has been amended).

Many people seem to forget that bridge is a game for gentlemen and ladies where the prime concern is to obtain a "fair" result, i.e. to rectify rather than penalize every irregularity.

An extremely misguided notion.

Much closer to the mark is that bridge is a game where the prime concern is obtaining results by fair play.
Bridge is a game and I will remember that its place in my life is that of a game. I will respect those who play and endeavor to be worthy of their respect. I will remember that it is the most human of activities which makes bridge so interesting. And in doing so I will contribute my best and strive to conduct myself fairly. -Bridge Player’s Creed

While David's post may be erudite, and seems pretty reasonable to me, there is one exception: while saying that most revokes do not restore equity, he then ignores this in the rest of his post, and provides no evidence his assertion is true. Of course, the reason is that it is not true: as he knows very well, once the revoke penalty has been applied, very few revokes need a Law 64C adjustment because equity has been satisfied. Certainly it may have been satisfied with an additional penalty element, but that's irrelevant: equity has been satisfied.

I think the two of you are just meaning different things: one of you talking about the likelihood of the penalty giving NOS at least equity; the other talking about the likelihood of it giving exactly equity.

Anyway, I am fed up of explaining to people that they do not automatically get a windfall when an opponent revokes, so I think it gives exactly equity quite a lot of the time. I am also fed up of spending 5 minutes analysing a hand to see if I need to make a 64C adjustment, only to find out that I don't, so I would rather it didn't. Under the old rules it was often easier to check that no additional damage had been done.

[I am talking here as a playing TD when there is time pressure on every ruling; of course when I am non-playing I am quite happy to have a hand to analyse even if the answer turns out not to be interesting.]

the randomness of the penalty is what puzzles me, also I am afraid of cheaters revoking against bad players who won't review deals when they are not making any more tricks unless revoking, it seems to be a free shot under current laws.

Martian: "What is equity?"

Earthman: "Equity is satisfied when a thief, on being immediately apprehended for the crime of stealing a dollar, is compelled to give his victim two dollars."

Martian: "I see. Tell me - if the thief steals three dollars, must he give four dollars to his victim, or six?"

Earthman: "No, no - only three, for equity is thereby also satisfied."

Martian (into communicator): "Prepare to return to base - our journey has been wasted. There is no intelligent life here."

I think it is safe to say that the actual aim of the present laws is to have an automatic "rectification" that is the smallest consistent with ensuring L64 adjustments are infrequent. More controversially, one could characterise that as more being about minimising the work of TDs than any careful consideration of punishment or equity.

I wish to reiterate Campboy's comment: DBurn is saying that the revoke laws rarely restore exact equity (which I disagree with; with the new change in my experience it's more like half the time, and I have Campboy's issue with that as well as "you know, I kind of liked the penalty the way it was before; people revoke less when it costs more"); Bluejak (using screen names to avoid confusion) is saying that the revoke laws rarely do not return at least equity (which is probably true, but less so than before, and that's annoying, too; more time-consuming investigations are required, most of which don't change anything).

So, both right. The argument over whether revoke rectifications should be penalty-oriented, equity-oriented, or ease-of-application-oriented is interesting, but for another forum I guess.

Well, almost both right. The first sentence of the Earthman is able to confuse: "A thief, on being immediately apprehended for the crime of stealing a dollar, is compelled to give his victim two dollars. Equity is satisfied, and more, of course." The Martian's later question (which will come) of why $1 gets punished, but $3 does not have an additional punishment, is again, legitimate, but not for here.

I leave you with a question that was asked in another place a couple of years ago: You hold AKQJxxx on lead to 3NT. You lead the K, and partner shows out. What do you do now?
