I think that this is not the line that gives the checkmate in less moves, and there are some variants that I didn't analyze, but the fact is that this is certainly a variant that takes to the checkmate. Same not analyzing some lines, I don't believe that blacks get to drawn. Where you found this position? 1... Nf5+ 2. gxf5+ Kxf5 3. Kd4 Ke6 4. Kc5 Kd7 5. Kb6 Kc8 6. Bg3 Kd7 7. Kb5 Kc8 8. Kc6 Kd8 9.
