It is all of those things.


If you think that is true, why hasn't anybody (including you) answered Nigel's questions yet? I'll repeat them for your convenience:

The second rule might reduce the frequency of common mistakes. For example :( quick answer - no consulting the Orange Book :) In the following EBU auction, when is the double alertable?

1N "12-14" (Pass) 2 "Spades" (Pass)
2 (Double)

And what if 2 is alerted (usually but not always) and 2 denies four ?

I would say that Nigel's questions are easy to understand, so if the OB rule would be simple, easy to understand ... etc. it should be straightforward to come up with the answer, without looking in the OB.

The answer is that it's alertable if not for takeout. In both cases the 2 bid shows willingness in the context of the auction to play in spades.

I haven't looked in the OB (as requested by the examiner!). For the first Q I would expect any double other than a TOx of spades to be alerted, and I would expect this to be more or less universally understood by the people I play with and against. The second is slightly trickier, mostly because you haven't defined "usually", but I would expect the answer to be the same as in the first case.

Edit: I see Gordon has replied while I was drafting this. At least we are consistent, and I don't think this sort of auction generally causes the sort of problem in England that those asking the question implicitly seem to assume it does.

I am not currently in the EBU and may not be up to date with the OB but I would think that 2 in the original auction is an offer to play in partner's suit and therefore natural - so any meaning other than takeout is alertable. Whereas 2 in the second example is a form of pass/correct and therefore artificial - hence any meaning other than showing spades is alertable. I am sure that regular EBU players can give a more definitive answer though.

Usefully, in the Orange Book we are told:

Quote

5E(a) Suit bids that show the suit bid.
Double of these bids is not alertable if for take-out; alertable otherwise
.
and:

Quote

In 5E2(a) and 5E2(d) the word ‘show’ is defined as follows:
‘it is natural, or shows willingness, in the context of the auction, to play in the suit, or it
is followed by two passes’.

That deals with the situations under discussion.

Right. In that first auction the double is not alerted if it is takeout of spades; if it is anything else it is alertable.

In the second meaning of the auction you are have most likely agreed to treat the sequence as showing spades and still if your double is takeout of spades it will not be alertable. Maybe you have agreed that it is showing spades though. Or general values. Then you alert. None of this required looking at the Orange Book.

I do not know what regulation is supposed to be more effective when the opponents' auction is potentially ambiguous. You have to assume something, and your doubles and other calls will be based upon that assumption.

The 2 bid looks a lot more like an acceptance of a transfer, since that, apparently, is what the what the auction usually means. But again, a different regulation does nothing to solve the difficulty here.

I didn't reply because it didn't please me to do so. But I did know the answer, because I have read the rules that we're discussing.

The answer is that it's alertable if not for takeout. In both cases the 2 bid shows willingness in the context of the auction to play in spades.

A 1 opening, overcall, or response to 1m shows a willingness to play in spades.

A raise, a preference bid or even a false preference bid shows a willingness to play in spades -in the context of the auction.

To me, and most other players, accepting a Jacoby transfer to spades does not show willingness to play in spades, and it certainly doesn't when the context of the auction comes into play.

  • Opener normally has shown at least a doubleton spades by opening 1NT, which -I suppose- shows a certain willingness to play in spades.
  • Then responder's 2 shows responder's willingness to play in spades.
  • By accepting the transfer opener doesn't show any additional willingness to play in spades. So, in the context of the auction, 2 does not show willingness to play in spades.

1NT showed willingness to play in spades, 2 did that even more, but 2 is the only bid in the auction that doesnot show any willingness to play in spades. Keep in mind that I can only show my own hand, I can't show partner's hand.

If anything, 2 denies (or tends to deny) willingness to play in spades - in the context of the 1NT opening. Many players will make some other bid if they want to show willingness to play in spades, that is: more willingness than they have shown in the context of the 1NT opening. Nigel's second case dealt specifically with that: a 2 rebid that denied showing willingness to play in spades.

So, depending on the partnership agreements and style, 2 either shows that you don't have any willingness to play in spades or it doesn't show anything at all. But it never shows a willingness to play in spades (and certainly not in the context of the auction).

What you mean to say is that 2 is a bid that -due to the context of the auction- may well designate the denomination of the final contract or may well be passed out with the opener's side landing in at least a 7 card fit. But that is entirely different from "showing a willingness to play in spades".

So:

  • if you have agreed to treat the opponents' sequence -which is not showing spades- as not showing spades, then double for penalty of spades is not alertable?


Isn't your alert or non-alert supposed to inform the opponents what you have agreed? If your non-alert can be either takeout or penalty, depending on how you agreed to treat the opponents' sequence, then that is not very informative to the opponents, is it?

Sorry? You alert or don't alert according to your agreements. Of course. And if your agreement is that double is not takeout of spades, you alert. I don't know how you managed to misinterpret what I wrote previously.

I am curious about what your preferred regulation would stipulate.

I think that I sketched at great length that I want it as short as possible. Some posts in this thread: #3, #60, #65

From #79:

 Trinidad, on 2013-February-28, 18:24, said:

2) A short, concise regulation that is easy to understand for every player. This will come with a grey area (which is easily solved by "when in doubt, just alert since it encourages the opponents to find out").

It is clear that I opt for the second one: a regulation that is easy to understand for everyone. Why? Because bridge is intended for everyone and not only for visitors of bridge laws forums.

and from #82:

 Trinidad, on 2013-March-01, 04:47, said:

..., something like:
"Alert when you expect that your opponents might attach a different meaning to partner's call. When in doubt you alert."

The 2 bid is made in the context of an auction where it may well be the final call. Of course it shows willingness to play in spades, just as it would if I gave preference to a singleton, or responded to a Multi 2 in my void. If I weren't willing to play there, I'd have to bid something else.

You still misunderstand. The 2 bid "usually" showed spades, so you treat 2 as a normal completion of a transfer for the purposes of alerting. If, however, you have decided that your double will be something besides takeout of spades, you alert.

In short: double=takeout of spades, no alert; double=anything else, alert.

Quote

"Alert when you expect that your opponents might attach a different meaning to partner's call. When in doubt you alert."


Right. And this is a) easier to obey and b) more helpful to the opponents than the above. Not.

Broken record:
  • Alert non-penalty doubles OR
  • Announce doubles that are penalty or take-out. Alert others.
Such regulations are short, simple, easy to understand, easy to obey, and easy to enforce. They are likely to achieve the intended efficacious effect, efficiently.

Alerting negative doubles was tedious. Alerting first-round takeout doubles will be more so.

    Again, the most common doubles will be announced, and it will be annoying.

    Is "Alert non-penalty doubles of NT bids, non-takeout doubles of natural suit bids, doubles of artificially bid suits that don't show the suit, and unusual doubles above 3NT" really that long and difficult to understand?

    I honestly find it hard to believe that anyone who has actually read the above can imagine that it is not "short, simple, easy to understand, easy to obey, and easy to enforce".

    Well, "simple" needn't apply only to regulations.

    Vampyr may have overlooked gnasher's view (shared by many)

    gnasher said:

    The real answer is for the L&EC to change this ill thought-out rule (5B10, I mean - the rest of the alerting rules are fine).
    Anyway, IMO, you are allowed to express an opinion even if you aren't an EBU member. This kind of problem is common to all local jurisdictions. Analogous instances, IMO:
    • How ACBL Stop-card regulations work in practice seems bizarre. (but most ACBL members seem happy with their fool's paradise).
    • Local System-card and Disclosure regulation is harmful to the game. Thus, Australian LOLs enjoy playing multi and so on although other legislatures seem to adopt a chauvinistic spoil-sport attitude. (But EBU members like Gnasher and Vampyr endorse such protectionist policies)
    • The Having none rule flouts the principle that communication between partners be confined to calls and plays. (But players in most jurisidictions are increasingly following American practice -- switching to attitude rather than count signals).
    • Bidding cards should be left face-up until after the opening lead is faced. (It's hard to understand how anybody can object to this).
    • There are other similar examples on-line. (If the law-book contained sensible default laws, we could begin to eradicate these anomalies}.

    :) The regulation is unclear to simple-minded players like me :( It is hard enough to define take-out and penalty, without unnecessary controversy as to what is natural and artificial.
