Licensed in the EBU? ( 09:09:48 WedApr 23 2003 )

Country: England

Our county magazine recently had an article on 'diabolical two-bids' where, NV, you open _every_ hand of 0-7 HCP with 2 of its longest suit (or higher with a normal pre-empt). So xxxx xxx xxx xxx is a 2S opening, though xxxxx xx xx KQJ10 is a 2C opening for the lead. A pass shows 8-11 HCP (and is of course alertable).

The author claimed that this approach is licensed at level 2. I couldn't find anything in the Orange book to contradict him, but this type of destructive approach seems rather against the spirit of level 2 (and level 3). The author also mentions that you would play a different set of two-bids vulnerable, but I assume this wouldn't then count as a different system.

For level 3+ he suggests playing 1NT as the strong opening bid. If 1NT is not the strong opening bid vulnerable, I assume you would then argue that this is in fact two different systems and hence not licensed.

Any comments?

I'm not sure, but...

It seems to me OB12.6.3(a) specifically allows the 2-bids. However, I can find nothing that allows the conventional pass. Unfortunately, I can't find anything corresponding to the ACBL's "if it's not specifically allowed, it is disallowed" statement. So I'm not sure if the pass is allowed or not.

At level 2+, you are allowed to vary according to vulnerablility the range of a natural 1NT opening. At level 3+, you are allowed to assign an artificial meaning to the bid, but as it is not natural, you can't vary the range. So is this 1NT natural?

I think the idea is that 1NT is artificial and strong (as you have removed all the strong 2-bids from the system) NV, but natural V. You clearly can't do that at L2.

I was also interested to find nothing about conventional passes. It seems that if I want to, I could play a system like this at level 2:

1NT = 0-10 balanced (with no conventional continuations)
2C/D/H/S = nat, 5+ cards, 0-10
Pass = 11-14 balanced
1C = nat or 15+ balanced
1D = 4+ cards, 11+
1H/1S = 5+ cards, 11+

I'm not suggesting it has any bridge merit, but I thinking I'm missing something in the regs if this is licensed!

The suggestion was to do it at L3, but I don't think it's legal there, either.

Frances suggests playing 1NT = 0-10 balanced with no conventions.

If you had asked last week, I wouldn't have known. But one of the U19 pairs tried playing this last weekend. Mike Amos thought it wasn't permitted and eventually found this (in the Orange Book):

7.4 Law book options
7.4.1 Certain Laws have Zonal options. European Zone options are:
Law 12C3 applies, so an Appeals Committee may vary an assigned adjusted score in order to achieve equity.
Law 18F authorises such methods as Bidding Boxes and Silent Bidders.
Law 40D has been delegated by the Zone. The EBU does not allow opening 1-bids on such hands (typically 7HCP or weaker) except in
some cases at Level 5.
Law 61B applies in full, so defenders may not ask each other whether they have any cards left of the suit led.
Law 93 allows the possibilities of differing methods of appeals and thus permits special methods to deal with special cases.

So, as well as the permissions in sections 11, 12, & 13, no opening 1-bid (including 1NT) can be made on hand a king or more below opening strength.

As mentioned in another thread, we have not "licensed" anything since 1998. Conventions are now "permitted" {or not}.

Most of your questions have been answered. I would not dream of mentioning how Mike Amos found what he did but I doubt he would have if mobile phones {cellphones} had not been invented! :smile:

We do not feel we need a regulation that if not allowed it is disallowed. We have a list of permitted conventions and anything not on the list needs no further comment to be disallowed. So pass showing values is not permitted.

To play an artificial 1NT opening at one vulnerability but not another is to play two separate systems, only permitted at Level 4 in seven-board or longer stanzas.

Mike probably remembered the first time this came up which was about 4 years ago when myself and partner played at the Bournemouth Spring Pairs. We were playing 0-14 3rd in hand 1NT. None of the directors corrected our system although there were plenty of calls by our oppenents and Mike was involved in several of these. It wasn't until several weeks later that we recieved a letter advising that zonal requirements made this treatment illegal.
