      Very interesting! About the tournament I’d like to mention also that the theme in the announcement sounds:

      Theme: Help-selfmate in 2-4 moves (HS#2-4) with the Zabunov theme – the front piece from one battery makes an ambush move and becomes the rear piece of a newly created battery.

      with a nice addition:

      Anti-batteries and other type specific fairy batteries can be used too. Fairy pieces and conditions are allowed…

      Myself I enjoyed playing with Zabunov theme and its variations a lot! Starting to compose for this tournament in summer, for now I’ve submitted 3 problems to Diyan, and the same time have composed 3 more problems which are not Zabunov (or not pure Zabunov), but were inspired by this theme. Fairy pieces, fairy conditions, anti-batteries give so many possibilities that starting to compose with Zabunov theme it is hard to stop! 🙂
      Oh, well, I’d like to wish to all of you to try and to enjoy this theme! And also I have my own interest here: I’d like to have more competitors for myself! 🙂

        Does my No.350 show the Zabunov theme also? If so, Of course it is incidental. My main idea there was quite different.

    Yes, Ram, it is also Zabunov because after the initial battery with forward piece R follows creation of a new white battery B/R where the Rook is already rear piece. It is a specific battery-transformation – Zabunov with only two thematic white pieces. But here this theme is not the main component of the content, as you say, but only a small nice additional motive. Of course there is a realization of theme only in 1 variation.

  3. Nikola Predrag says:

    Formal definition of the theme Zabunov requires an ambush move. The interpretations of a formally strict ambush and of an essential but not formally strict ambush, seem not very consistent. If some controversial examples might be benevolently accepted, a better question is perhaps “what can not be accepted as an ambush move”? 🙂

    How can the Seetharaman’s No.350 show “Zabunov” with an ambush move? The check by rear battery piece wBh5 is completely irrelevant, wB would be just as good on h7, initially.
    After 1.Rxg1+[+bRh8], Black must play 1…Rh8xh5[+wBf1] because of the check by wRg1. This is a direct attack on bK, not an ambush. Even if we speculate that after 1st black move, some kind of ambush is arranged by the arrival of wBf1, this is not a result of the initial battery and wB as the rear piece.

    The convincing complexity and beauty of some theme emerge from the motivations and reasons for the play. A completely genuine “Zabunov” should use the potential of the initial battery to gain just enough time to arrange another battery. Without such a tensive motivation, the mechanism is merely ornamental and the true theme is not presented.
    It looks impossible to present a true “Zabunov” in hs#, but in the ingenious example No.4 from the announcement (Tzuica 2009,2nd Prize), Petko Petkov has shown the way how to do it.
