  • Subject: Paragraphs 7C1(A) to 7C1(D) (inclusive) of 2024 Blue Book

    Has anyone got a list of examples of the strong bids that would be permissible under the above paragraphs covered in the 2024 Blue Book ? There is a lot of good stuff covered in these paragraphs about strong meanings, non-strong meanings, the number of cards in the suit called or not etc etc. I need to explain all of these in layman's terms to our members. So if anyone has prepared a paper or have some examples that you could share with me, it would be greatly appreciated.
    Thank you.

  • The Blue Book uses the term "semi-balanced" and has the following definition of balanced:

    Distributions [4432], [4333], [5332], [5422] and [6322] are balanced;
    all other distributions are unbalanced

    but there is no definition of semi-balanced.

    I think I know what it is but can anybody supply clarification?

    I think 'semi-balanced' is only used once in 6G2. This appears to be the only occurence of 'semi'.

    In addition, 2C can show a (semi)-balanced hand with three or more clubs (‘Roche’)

    I think 'balanced; is no singleton or void, at most one doubleton; and semi-balanced is no singleton or void, at most two doubletons.

  • Thank you. That is what I thought it was.

    I think 'balanced; is no singleton or void, at most one doubleton; and semi-balanced is no singleton or void, at most two doubletons.

    However, the definition of balanced included two shapes that have two doubletons - 5422 and 6322

    Presumably then, semi-balanced includes singletons, such as 5431.

    I play a wide-ranging NT rebid with 1 partner, of 12-16, such that after 1D - 1H - 1NT shows 12-16 and balanced(ish) - soften it includes a 12 point hand with a singleton H.
    I will occasionally overcall 1NT with stops in the opening suit but a shortage in a side-suit.
    For example 1H - (1NT) might have S: Q, H: AQ7, D: KQxxx, C: Axxx (can't pass, 2C looks like a poor representation of my hand and a double can get me in trouble after partner bids 4S thinking I had more than one.
    I would class that as semi-balanced in my mind too.

    Blue Book "balanced" is not what "I think 'balanced'" is or was. In fact, Blue Book "balanced" is what I think of as 'semi-balanced'. That is why the Blue Book does not define "semi-balanced".

    Blue Book 6D2 (and much of Section 6) did not fall under the same scruting as Section 7 when the new glossary definitions were introduced. In 6D2, "(semi-)balanced" can clearly be replaced by "balanced.
