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)
