Multi 2D ( 01:01:50 ThuJan 30 2003 )

This post was copied from the former IBLF site on Bravenet.

Here is my question on Multi 2D

Background

I live in Spain and play mainly in Europe ( France & Spain but not in the UK)

Is it permitted to play the Multi 2D with the following 2 elements:

1) Weak 2 in either Major 5 or 6 cards. If only 5 cards will be accompanied by a 5 card minor suit 5/10 hcp

2) Balanced hand 21/23 hcp

If this is not permitted is it possible to play the Multi 2D in a format which varies with the vuln.? Ex:

Non Vul

1) Weak 2 in either Major - 6 card suit 5/10 hcp

2) Bal 21/23

Vul

1) Weak 2 in either Major - 5 Card suit with 5 card Minor 5/10

2) Bal 21/23

Thanks for your help

this depends on the convention regs where you play (France and Spain, you said), and I'm afraid I don't know what those are. I'll have a look on the web, but it may take a day or two.

when the basic legal requirements essential to an opening hand were established it was found that the multi 2D did not meet this criteria but it's use was so widespread that an exception was made.
to include additional configurations it is necessary that these meet the permitted criteria.
for example a 4-4-4-1 shape with 17 high card points may be used within the 2D framework as it meets the legal requirements of a total of 25 "opening points".
this point range is required because in the given example no anchor suit is given.
this is not the case with a 5/5 in a major (which major?) and minor suit simply because it's opening point structure has a maximum of only 20 ops with no anchor suit identified - "anchor" being an identifiable suit.
such a bid would be legal if the bidder held 15 hcps.
it is legal to bid 2h with 5h and a 5 card minor and 5 hps as the heart suit is identified therefore the op range reduces to 15.
the definition of opening points is-
the sum of the number of cards held in your 2 longest suits and your high card points.
a 1 level bid requires 18 ops.
2 level 15 ops.
3 level 15 ops or 12 ops if the hand contains a 7 card suit
you may deviate from this occasionally but must not have an agreement to do so.
in each of the above it is mandatory that an anchor suit be identified.
it is not necessary to identify a suit if your opening points add to 25, for example a game force bid of 2C should show these 25 ops.
in the case of no trumps a balanced 1nt bid should show the 18 ops mentioned but may be unbalanced if holding the 25 ops mentioned.
an opening 1nt bid is illegal if the shape is 4-3-3-3 with only 10 hcps.
confused?

Yes.

Is this applicable in Spain, or in France, or in both?
