No.612 Kenneth Solja – Три черных превращения! (JV)

No.612.1 Kenneth Solja & Ladislav Packa – Новая версия задачи No.612, созданная в процессе долгой дискуссии! На один полуход длиннее, на одно решение больше, с жертвами белых фигур! (JV)


Определения:

Anti-Andernach: Фигура (за исключением короля) меняет свой цвет после любых ходов без взятия. В случае взятия фигура сохраняет свой цвет. Ладьи на a1, h1, a8 и h8 могут быть использованы для рокировки, в случае, если выполняются остальные необходимые условия. После рокировки ладьи не меняют свой цвет. Если белый делает ход без взятия нейтральной или полунейтральной фигурой, эта фигура становится черной, и наоборот.

    Probably can also do a complete AUW, I’ll try it tomorrow – today it’s too late:-)

        Repeating the same mate (Q/Rxc6) should be avoided to show a true AUW, it is surely possible in various ways.

        • Laco Packa пишет:

          Of course Nikola, you’re right. But it was only the first shot, just to be shown that it is possible AUW. One of the possible ways to remedy shortcomings here:

    I manage to do myself the AUW as well:

    I like the knight-promotion here because knight move to e3 is not blocked by pawn, but 1.-Se3 is a check.
    And I dislike bishop-promotion, because it doesn’t end to bishop move, but battery mate.

      I offer this correct version, nothing more economical I could not figure out:

      Interestingly, despite the external similarity with 578 the moves have other motivation.

      • Nikola Predrag пишет:

        It’s not easy to say what is the best possible economy, since 4 extra bPs are there only to be captured. The “geometric” potential of the board should be explored to reduce the merely obstructing pieces.

        Still, some Pawns might be spared in some better scheme.

        • Laco Packa пишет:

          Well, I did not write anywhere that I managed to make the most economical position … You saved some material – nice work. But it interested me another option to enrich the content. The intention is probably clear from the example that although is correct, but to perfection still a lot lacks.

  3. Nikola Predrag пишет:

    Yes, it was clear that you did not say that your position was most economical.

    I just wished to say that it is hard for composer to be sure about the economy as long as there is one technical piece.
    And it’s not easy to say: “I don’t see how to do it better.”
    But next day some idea might come and third day comes another idea….

    Now, your new idea indeed enriches the content, so go on.
    So far, the biggest flaws are the idle wBe7/wBe8 in the mates by Q/R. But the idea is worth working on it.

    I got two black pawns off, but solutions stay the same.

    I manage to save only one piece compared to Laco’s original. Comments?

  6. Nikola Predrag пишет:

    That’s very nice.

  7. Nikola Predrag пишет:

    The scheme is now working very fine and it seems that nothing could be changed. Nevertheless, some other positions of bK could be examined.
    A very nice idea deserves to be presented in a best possible way.

    I hope that before the publication, you will at least improve the obvious details in economy.

  8. Nikola Predrag пишет:

    My post was in vain. Please, could someone be so nice to explain me the surprising purpose of bPa5/d4?

    • Laco Packa пишет:

      Simple question, simple answer.
      The composition de jure does not exist until it is published. Its notation was yet in the discussion freely accessible to everyone and anyone can publish it under his own name. But for its possible repair is sufficient time (which currently I do not have) until the award of the tournament.
      I did not want to write it directly to the discussion.
      Therefore, it was (one of several) reasons why I asked Julia to your email address …

      • Kostas Prentos пишет:

        Laco, the way I understand the matters of publication, priority, etc, according to the Codex, but with an attempt to modernize and include the proposals that appear in a website like this, is the following:

        Any position that is shown, in diagram or notation, as part of the comments to the original problem, is or should be considered a separate problem. Since the formal type of the publication is not followed, regarding names of composers, source, etc., I believe that a good solution would be to consider each proposal in the comments as a version of the original: e.g., Kenneth Solja, (version by Ladislav Packa, or Nikola Predrag). If the involved composers agree on a different arrangement (like in the case of 612.1), they can publish one of the versions as a joint problem.

        Any comment that includes a problem, version, sketch, scheme or anything else, from the moment it appears in this (or any other) website, it becomes public property, meaning that everyone can see it. For example, if I wanted to write an article about AUW in fairy chess, I could use any of the positions appearing in the comments of this problem, and for lack of a better system, I would use the form I proposed earlier (KS, version by X, Julia’s Fairies and the date). As a matter of fact, I believe that all the positions in the comments should participate in the informal tourney and be considered by the judge (sorry Kjell, and future judges), whether they were deliberately composed to participate or they were composed just for fun, or to show an idea, or make a point. Of course, most of the times, these intermediate positions may not have any particular value and only the final version becomes a “diagram”, but it is not unlikely that one of the versions that was “rejected” by the participating composers, may be more appealing to the judge.

        In any case, the positions “shown” here at the comments, take priority as if they were published problems, and therefore any attempt to “steal authorship” would inevitably fail as anticipated.

        • Laco Packa пишет:

          I agree with you, Kostas, your arguments are clear, logical and above all ethical.
          However, I think that it is better to avoid conflicts and not give them even the slightest chance to be born.

      Pawns bPa5/d4 are moved from No.612.1 by request of Laco Packa, after comment by Nikola Predrag.

  9. Nikola Predrag пишет:

    OK Laco, thanks for the answer.
    Sometimes I forget that it’s the public place.
    And it would be quite a corrupted mind which would try to steal the authorship in such an obvious way.
    But perhaps you’re right, there are various kinds of minds.
