Plan: 1. Bc5 (2. Be7#)  Kg5  2. Be7+ Kh5

3. Rg7 ~ 4. Bg6#,  but 1. … Nxc5!

It is preliminary necessary to destroy a black knight,

having enticed it on a vulnerable field: c7.

But early 1. Bb6? (2. Bd8#)  Nc7?,  из-за 1. … Rd2!,

therefore overlapping in the beginning prepares on d7.

1. Bf2! (2. Bh4#) Kg5  2.Rg7+ Kf6 

3. Rd7  Kg5  4. Be3+ Kf6,  then hunting for a knight:

5. Bb6  Nc7  6. Bf2  Kg5  7. Rg7+  Kf6 

8. Rxc7  Kg5  9. Rg7+ Kf6  10. Rh7 Kg5 

11. Be3+  Kf6  and now passes the main plan:

12. Bc5  Kg5  13.Be7+  Kh5

14. Rg7~ Rxe2  15.Bg6# (model)
