Ok I go for:
1. f7+ Kg7
2. Qc5 Qh4+
3. Kg1 Qe4 (black have to protect both e5 and d4)
4. Qf8+ Kf8
5. g7+ Kg7
6. f8Q+ Kh7
7. Rf7#
as a main line
Anon 10:34,
If black plays
5. .. Ke7
it would take more than 10 moves to mate.
Somewhat contrived, but a mate in 10 nevertheless:
1. Qc5 Qh4+
2. Kg1 Qe4
3. Qc7 Qe3+
4. Kh2 Qe7
5. Qxe7 Rxf6
6. Qh7+ Kf8
7. Rxf6+ Ke8
8. Qf7+ Kd8
9. Rd6+ Kc8
10. Qc7#
It seems Black can be checkmated in 8, the trick is white’s 4rth move.
1.f7+ Kg7
2.Qc5! Threatening Qe5#.
2…Qh4+ [2…d3 3.Qe5#]
3.Kg1 Qe4 What else?
4.Qd6! Threatening Qf6#.
[Also wins :

(5…Kxg7 6.f8Q+ Kh7 7.Rf7#)
6.f8Q+ Kd7
7.g8Q Qxg2+
8.Kxg2 c3
