Ужасное вступление у Зинчука подсказывает, что автор с такой техникой, вряд ли, сам придумал основную схему. Поиск подтвердил догадку — она из этюда Асабы 1977 года:
The bishops chase each other, and the knight dances like a whirlwind, but still, White has the last word. Reminiscent of the famous Liburkin study. Pity that the a5 pawn is standing around, needed to avoid that e.g. 3. Ra8 wins. GIven the Zinchuk study, of course, this miniature is not more than a version, but I like it very much!
The duals in move 9 (Kd2, Ke2, …) do not disturb me at all, but they may be noted.
Here’s the version with the black pawn used in the main idea.

I am uncertain whether this version is an improvement. The mainline remains for me 5… Kf6 where the play is richer and White needs to avoid the temptation 8. Rh4? Kg5!. But then the h-pawn adds little. Moreover, the duals 8. Ra4/Rb4 are slightly annoying: even if it is always about Black’s pieces on the sixth rank, 9. Rd6+ is a check and 9. Ra6/Rb6 a pin. That was actually good about the a5 pawn. Finally, we have to cut the first two moves of the play in this version. So probably the author managed to find the optimal version.
Good that you gave 3.5 points, Serhiy. I was uncertain between 3 and 3.5 and in the end opted for 3. But that is perhaps a bit too strict.
В одном Альбоме 1980-82 годов со своим полным предшественником из 1977 года!
