No.588 – S.N. Ravi Shankar & N.Shankar Ram – Коллективная работа двоих индийских друзей с незапрограммированным условием All-in-Chess. Shankar Ram пишет о нем: “All-in-chess is a somewhat obscure and untried condition. Which is perhaps the reason it has not been included in Popeye and WinChloe. Apart from the inventor – Dr Chris Tylor of U.K, only Ravi and I seem to have worked on it with any regularity.” (JV)


Определение, присланное авторами:

All-in-Chess: Each side may move pieces of any colour, but may not repeat the position reached after the previous move.(Currently, neither Popeye nor WinChloe include this condition. So, the problem below is C-).

    Interesting condition. Shankar & Ravishankar has been composing many problems in this genre, more recently Ravishankar. This is a funny problem ! Enjoyed playing the solution !

    Thanks, KS!
    Here’s a simpler introduction to this condition..

    Beautiful example of the condition. Perfect economy would perhaps compensate for the key that does not belong to the genre #3.
    But there is a deeper relation between this fairy condition and the genres of chess composition.
    In a helpmate, both black and white pieces move for the purpose of White. And that’s exactly what happens here.
    AIC allows Black to move white pieces for his own purpose but the key makes it impossible.

    This is essentially a helpmate, stipulated as #3 as an easy way to avoid the cooks.

      Nikola, thanks for your comment! Your interpretation of the condition as a sort of help play is interesting. But this is a direct mate and we conceived it as such.. We didn’t do it like..”Hmm.. here’s a nice helpmate idea.. but too many cooks.. tch.. tch.. hey! wait.. if we make it an AIC #3, then voila! all the cooks disappear..” 🙂

      • Nikola Predrag пишет:

        Oh, of course I didn’t think that you conceived it as a helpmate idea, but that a realization shows a help-play essence and too little of a direct-mate fight.

        The key reduces all black legal moves to only two. That is a very hard restriction even for an orthodox threemover.
        From an orthodox viewpoint, the overall artistic impression might perhaps justify such a key and support Seetharaman’s opinion about FIDE Album. Grimshaw achieved with 2+2 pieces (+wK)!

        But how the fairy condition is used for that? Without AIC, there’s no #3! AIC serves only White’s purpose.
        Black can’t use the condition for a defense in thematic variations.
        The essential features serve only White and that’s the help-play essence.

      I think this is more akin to neutral pieces.

    Incidentally, all the black’s rooks and bishops are captured by Black!
