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?
>> 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.
>>What is the idea of the first two half-moves?
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.
Hello Aleksey,
Perhaps the following small orthodox and fairy changes also deserve attention:

Dear Janos,
Your 1st version (with Bf2-g1-f2) is interesting but 1st White move is “almost automatical” – it reduces a value of a switchback, to my opinion (the switchback became almost artificial). Also my version with wide moves Bd8-h4-f2 likes me more.
Your 2nd version is probably interesting too but I practically almost don’t compose problems with fairy pieces and I think that it is better to try to realize some idea with orthodox pieces 🙂
But nevertheless thank you for these versions!
Dear Aleksey,
The World is beautiful because it’s colorful! It is important that we understand each other despite the differences! Of course, I accept and fully respect your opinion!
Best regards,
Janos
