Should we consider the class of player involved?

I think it is the "class of players in question" phrase that is confusing here. If you can completely understand all the thought processes of the player at the table, then:
a) the "class of players in question" is probably reduced to just that one player;
b) you have a very good basis for determining what (and how frequently) that player would consider and do in the absence of UI.

I think the goal should be to approximate the proportion of the time that, absent UI, the player at the table would consider and select a particular action. The "class of players in question" should be sufficiently restricted that L16B1b takes on this meaning.

In reality, you cannot completely understand his thought processes. You may be able to find out sufficient information that it is clear whether there were or weren't LA's. You may be able to find out sufficient information that you can identify a group of players with similar traits in the type of situation in question to poll. Either of these outcomes will trivially result in a sensible ruling.

I suspect that what often happens in practice is that "class of players in question" is interpreted too loosely (or maybe too literally) as "players of a similar level of experience and/or results", a poll of whom may well contribute nothing towards a sensible ruling, but is simply percieved as the process to follow. I hope nobody would conduct a poll of such "peers" and as a result impose an LA on the player in a situation where he was able to provide a flawless logical argument showing why, for him, there was no LA.

Good players are not benefitting from the laws, they are benefitting from being good players. Is it unfair that when you play against a good player, they are less likely to do something very bad than a bad player?

Is fair in your world to make a good player do something that none of his peers would do, and that would not be a logical alternative to him by any evidence? Of course not, that is not fair, that is simply punishing him for having his partner hesitate. He does not all of the sudden become a worse bridge player when his partner hesitates.

So, is this unfair to the bad player, who must be forced to make this bid that the good player wouldn't make because a poll of HIS peers indicated that it was a logical alternative? The laws are not the problem here, the fact that less skilled players might make worse actions in a bridge competition is part of the game. The less skilled player is punished for being less skilled, it is not any more unfair than when he takes a worse line than a good player and loses imps because of it.

At the end of the day, after the BIT or UI, we are trying to guess what might have happened at the table, and of those outcomes give the most favorable one to the non offending side. In this way, the offenders will never gain from their infraction, they are taking the worst result that might have happened. This does not mean that we throw in things that would never happen and give them an even worse result. And of course, in determining what might have happened, we must take into account the skill level of the players involved, how could we not? If we run a poll to determine LAs, we must poll people close in skill level to the offenders. The fact that some things are LAs to one class of players and not to the others is not an unfairness built into the laws, it is just a representation that more skilled players will often have a set of LAs that leads to better scores than less skilled players. Well, duh!

If the goal is to punish offenders and be punitive, fine, then lets say so and force them to make bids that they would not have made, or give them PPs, lol. But since that is not the goal then we must take skill level into account. Period.

One thing I always dislike about arguments on this and related subjects are posts and arguments that suggest the approach benefits better players: it doesn't. You get a sequence where a better player would do something a poorer player would not: sometimes that means we allow him to but not the poorer player: sometimes we do not allow it: it works both ways in different circumstances.


Abso-freakin-lutely.

When you go poll players for an infraction in the A section, you don't ask the cadddies and novices what they would do.

A players are better than B players, but this isn't what's really relevant. What is relevant is that good players make different decisions than weaker players. This can cut several ways and it doesn't necessarily benefit the better player.

Take a slow double of 5 removed by an A player to 5 that worked. Since a slow double at the five level is much less likely to be taken out by a good player's peers (not because they are ethical, but because, well its the 5 level), then a B player might get a favorable adjustment (based on a B's peers) and an A player wouldn't.

"Punished" is the wrong word. If my regular partner and I are playing against Justin and one of his peers, we will lose. This is almost guaranteed. Our loss is not a "punishment", it's a consequence of our being stupid enough to go head to head against a pair we do not have the skill to beat.

OTOH, if by some miracle we should happen to beat them, well, maybe that's a punishment - for them. :P

Let's forget the fairness thing for a moment. Can anyone come up with a formulation which can be applied evenly within a competition without a subjective reference to the quality of the players involved, whether that be the quality of the pair in question or of the field in general? This is the crux of the matter, is it not? Even if you do not think the current Law is "fair", is there anything better available? It is basically impossible to decide on the comparative fairness of a change in the Laws without knowing what the current ones are being compared to!

That's quite easy. Simply replace "the class of players in question" with "everyone who has ever played duplicate bridge".

Consider a simple case: you open 1, partner bids 4, you have what appears to you to be a routine 4 bid. Unfortunately you have some UI from partner. The TDs rule that you have two logical alternatives, 4, which partner will pass, and 4 "Last Train", which will encourage partner to go to the 5-level, and go off in 5.

You tell the TDs that you have never heard of Last Train in your 15 months of playing the game. Nonsense, say the TDs, it does not matter, we rule as though you were as experienced as the average of the field, and "everyone" plays Last Train.

Without disagreeing with your general position, this example is flawed since the TD's approach you posit would not meet the separate criterion of "and using the methods of the partnership" - if the pair in question had never heard of "Last Train" it would not be amongst their methods. You seem to be making the additional assumption that uniform methods would be applied as well.

The TD decided that "Last Train" was General Bridge Knowledge, not a partnership agreement, and thus played by the average player in the field.

I don't see that he would have to deem that the partnership plays it when they don't, whatever the deemed state of their knowledge. Your view appears to be that for ruling purposes all pairs would be deemed to be playing the same "average" system, which is going a long way further than the original suggestion as I understand it, and in an unnecessary direction.

The insurmountable problem lies in the fact that people are immovably wed to core beliefs that are false beliefs. For instance, of the bridge world as distinguished from TBW (the publication which I am about to cite), in October 1999 Jeff Rubens [or possibly Chris Compton] wrote that it is a universal belief of bridge players that no one should ever gain from his own side's infraction.

Actually, at the time the statement was not true (I did not hold that belief) as it was not universal; and in fact I believe that the notion is down right evil. Granted, it is likely that I am alone. My beliefs are founded upon reason: the consequence of the above is that innocent players must be treated as cheats in order to achieve such aim- and to my mind, that is unfair in the most egregious way.

Metrics do exist that consistently enough approximate fairness. But they can’t be enumerated in a few paragraphs, cut and pasted into WBF2008, and solve the supposed ills you want to solve. That is because the entirety of the principles in WBF2008 must first be shifted and you are unwilling to allow such a shift because doing so would conflict with your core beliefs.

In other words, the difficulty in law is finding Solomon to write it over the protests of interest groups.

I think that you probably are alone, but perhaps you misunderstand. It is inconceivable that Rubens (or Compton) was suggesting that players should never get a favourable score after committing an infraction; what was being said was that a player should not receive a score that was more favourable than it would have been had he not committed the infraction.

I would be astonished to find a player who did not agree with the above.

There are times when you can legally get a good score because of an infraction. For example, you have a balanced 23 count and, not seeing RHO open a weak 2, proceed to overcall 2. After the Director explains everything you correct to 3NT. Everyone else is in slam since partner has a very good hand, as indeed you would have been had the IB not occurred. The slam is excellent looking at your cards but does not make due to the distribution of the opps' hands. Do you (or Rubens or Compton) believe it is correct to adjust the score here? There are many other cases (bidding a grand is suggested by UI but fails on a first round ruff, etc) where playing strictly by the rules can give you a better score than you would have achieved should no infraction/UI have happened. I do not have a problem with this providing that the possibilities to gain are a level playing field for everyone and none is misusing the Laws to gain (IB/pause and bid to silence partner, etc).

I don't. I wasn't thinking about cases like this, where you do get a better score than you would have absent the infraction. Maybe it feels different in a way because the causal link is broken; you were in a worse position after the infraction but got lucky -- so your good result was in being lucky rather than directly because of the infraction.

Though this thread was prompted by my comments in another thread, I felt it best to refrain from posting here for a while since it was making my blood boil. I thought I'd better take time to cool off.

View Postlalldonn, on 2012-November-10, 15:57, said:

You have two players, a novice and an expert. They both have the same auction where their respective partners have bid 6NT but also transmitted UI that suggests raising to 7NT. Based on some sort of bridge logic, it can be demonstrated that raising to 7NT is the correct action. The expert would always have applied this logic. The novice would never have applied this logic. If you are forced to give both players the same ruling, one of these two situations will occur.
- The expert receives the score for 6NT, even though he would always have bid 7NT.
- The novice receives the score for 7NT, even though he would never have bid 7NT.
It escapes me how either of those outcomes could be considered "fair", especially if we consider the main purpose of the laws to be restoring equity.


In this situation, the expert presumably has bid what he/she considers to be a justified 7NT despite the potential UI. Opps call the TD and, again presumably, the TD buys the expert's explanation of why the bid was justified. Result stands. The expert is not penalised for their expert judgement.

The novice on the other hand has also bid 7NT (if they didn't there wouldn't have been a comparable situation, never mind a TD call). The opps object and the TD asks but does not receive a satisfactory explanation. Because of the possible UI the TD rules the result is 6NT+1. The TD has not taken into account the class of either player per se, but ruled on the basis of the evidence available concerning actual actions taken and their stated reasons for taking those actions. The novice is penalised, not for being a novice, but because they have actually taken an action they could not justify under circumstances where the law calls for circumspection.

With due respect to all the knowledgeable people posting here, this sort of thing is not what I am objecting to. Nor is it the situation that I perceived in the original thread. In that thead we saw (some) experienced well respected players and TDs considering whether moving past 3NT was justified or not based on whether or not the players concerned could or could not stop in 4NT based on methods that most were not sure that players concerned did or did not have, on theoretical auctions that didn't happen and compared to supposedly better pairs - when in fact the pair concerned have had success at comparable events anyway. That did not seem right to me, so I said so.

I found it particularly objectionable because with one partner, I have played a not dissimilar method to that in the original thread. Had we been at the tournament in question I am quite sure we would have been regarded as one of the less experienced pairs. I am also sure that I would not have brought a folder full of system notes that would have proved beyond reasonable doubt that moving beyond 3NT would have been a normal action for us or that we could have stopped in 4NT. Consequently we would have been ruled against by (some of) the learned posters here based purely on their perception of our level of experience. This can't possibly be fair.

Nick

P.S. And I also object to having to rule in such a manner if I am myself a TD, so it is not just a personal objection.

Perhaps, to move from Intermediate to Advanced, I should work less on my judgement and card play and more on my lawyering skills to present arguments for why a given piece of UI is irrelevant because of various pieces of AI can find if I think hard enough. Or perhaps I can only do this for Advanced -> Expert since there are too many LAs to cover at Intermediate level. Regardless, we still do not have an alternative to the existing Law. It does not seem right to me that you should be entitled to a better ruling just because you are a better player than your opponent (let's not kid ourselves, most of the time the current Law does favour the better team) - after all, if we know one team is better then why bother having the competition at all? Nonetheless, if there is nothing better available then what we have is "fair". Until someone has a better idea it seems pointless to have a thread in CL&R.

Eh. Well, I didn't start the original thread, nor this one and I am not a lawyer myself. I am just a punter who seems to get fairly regularly so alienated by the rules and regulations of this game that I walk away from it.

I suspect you are overstating the similarities between yourselves and the pair at the table. The situation in the original thread was:

1. They play a similar system to you.
2. One of them bid 3NT, which was both slow and horribly wrong. [You or your partner probably don't do this].
3. Partner of the 3NT bidder moved. He may or may not have made a good case for doing so, but it was not clear from the evidence in the thread. [You would probably have made a good case even in the absence of system notes].
4. The director ruled in their favour.
5. So did the appeals commitee.
6. A thread was started questioning the A/C ruling. The scope of the thread grew to question the means by which the ruling was reached, but since we don't know what evidence was considered and how it was used, many people felt that we could not draw any real conclusions.

4, 5 and possibly 6 suggest there is no alienation. 2 suggests that even if there is it is not you who is alienated.

In any event, it is the nature of rulings and appeals that somebody will often feel aggrieved. If you did get ruled against in this situation, the blame belongs with partner's 3NT bid rather than the laws.

That doesn't happen. The director properly gives little weight to the self-serving testimony, he doesn't just believe the expert as to why he bid 7NT.
