Probably not the most efficient finish after 5.Kb5, but I hope you get the point of 5.Kb5, right? You only need to consider black’s defenses if white had wasted the tempo with 5.Kxa5.
Alena
I had difficulty in finding Kb5.
If
5. Kxa5 Ne4
6. d7 Nc5
It’s only a draw
1) Qxa5+, Kxa5 (forced)
2) Ra1+, Kb5 (again, the only legal move)
3) bxc4+, Kc5 (forced)
4) Ne4#
Thanks for the puzzle! Took me 3 minutes to solve it, I have ELO 1751 😊

What is wrong with b4 for white?
The theme was immediately obvious to me, but it took about 30 seconds to puzzle out the pawn capture check

I liked the fight of the knights.
Alena, you will need to deal with 2. ….Nf6- this puzzle is more complicated than it looks since 2. ….Ke6 makes white’s task significantly easier.
1. Nc4+ Kf5
2. d6 Nf6
3. h6 Kg6
4. Ne5+ Kf5
5. h7 Nxh7
6. d7 Kxe5
7. d8=Q
And, now, you need to deal with 4. ….Kh7.
5. Kb5 a4
6. Ng4 a3
7. Nxf6+ Kxh6
8. Ng4+ Kg6
9. Ne3 a2
10. Nc2 Kf6
11. Kc6 Ke6
12. Kc7 Ke5
13. d7 Ke4
14. d8=Q
