multi 2♣/♦ are not considered brown sticker if the weak options are only a weak 2 in either major. however what's the wbf definition for a weak 2? is 4 cards permissible?

[Cascade]

At at least one event they insisted that the the multi had to be played exactly as in the convention booklet which they interpreted as six-cards in the major.

Some jurisdictions specifically define the brown sticker multi exception as six cards.

I think the position that it must have six cards is not justified if it is not stated explicitly. Certainly not on the wbf argument that it must be played as per the booklet as the booklet includes the possibility of qualifying the atyle of your weak twos and I would consider "5-card" an appropriate qualification.

The WBF system policy refers to the Conventions Booklet which is now part of
Guide to the Completion of the WBF Convention Card.

This says weak twos can be "standard" (fair 6 card suit), "undisciplined" (bad 6 card or fair 5 card suit), or "random" ("anything is acceptable"). That suggests they are expecting a 5 card suit, or they haven't thought of 4 card suits. So that doesn't help.

There are some oddities re the Multi 2D: nH response is pass-or-correct, for all n.
