Probably my mistake (adding this line). I will make sure to correct it in the final award.

I guess the main line should go 14. Kd1 (zugzwang) 14… Ka1 15. Kc1 and 1-0.
I am not 100% sure about the alternatives on White’s 12th move. Is 12. Kf4 Kb2 sufficient to keep the balance? (White’s bishop cannot move because of Kxa3. If 12… Bd3 then 13. Be8 and 14. Bc6.) For example 13. Ke5 Bb1 14. Kd4 Bc2 15. Be8 and now Kxa3 can be countered with Kc3. Same question for 12. Be8.
However, continuing the main plan with Ke2, Kd2 and Kd1 is clearly the safest and fastest path to victory, so if there are duals, perhaps they are not a big deal.
Serhiy: if we are in the business of giving duals, I think the following line is clearer: 12. Kf4 ~ 13. Ke5 ~ and now either 14. Kd4 followed by Be8 and Bc6 (answer Kxa3 with Kc3 and 1-0) or 14. Be8 if the a-pawn does not hang. I see nothing Black can do about this.
Of course your line is more forced, and this is a good thing, but it is very long. You even have to realize that at the end, there is no accidental perpetual or h5 falls with check.
Harold van der Heijden once wrote an article «A minor dual is not a big deal». Here we have a major dual, but still I am not sure how much of a problem it is. Of course, strictly speaking the study must get 0 points. But the dual is sufficiently hidden, and the solution sufficiently obvious that the aesthetic impression of the systematic movement survives.

А что будет, если добавить белую пешку на е5? Дуали не будет.Но будут ли другие проблемы?

Ok, let’s start with 12.Kf4 instead of 12.Be8. Anyway, the winning path is the same.
Right. It is transposition in the end.
