    4.Qa1-g1 is a critical move (exploiting the interference), not anti-critical (avoiding the interference).

    What is the idea of the first two half-moves?

      1) In my opinion, additional move of Bishop (1.Bd8-h4) a bit more “justifies”, “explains” its sacrifice because if 1.Bh4-f2 would be a first move then this sacrifice would look slightly “artificially added”;
      2) A half-move 1…g3-g2 opens a line for wB – so it slightly increases a level of help-play;
      3) A long half-move 1.Bd8-h4 slightly increases an impression of the problem in view of using of the most part of board.

      The idea is:
      – the critical field е5;
      – homebase (w).

        The thing with Alexey’s position is that nothing really interesting/original/hs#-specific happens until exf2+.

        In your version it just doesn’t happen for a few moves longer.

        In my opinion adding another white piece sacrifice could be very thematic (and challenging!)

          I thinked about it. And I decided to try to realize it in another problem with another scheme and concept 🙂

        Sergey, I saw this version but it has many cooks.
