As Grandmaster Yakov Vladimirov notes:
The position could have another task - a checkmate in five moves, since the solution shown is the only [1] way not only to checkmate, but to win in general. Such compositions are called sketch tasks.

Notes
- ↑ Actually, not the only one. Possible and 1.Fh8 Cb1 2.Kpf3 Ch7 3.Kpe3 Kpa2 4.Fa8 + Kpb1 5.Kpd2 Cg6 6.Fa4 Ch7 7.F: b3 Kpa1 8.Fa3 + Kpb1 9.Kpc3 Kpc1 10.F: b2 + Kpd1 11.Fd2x, so it’s proper to call this composition only a math task in 5 moves , and not an etudes task.
