You already got two answers with small time. Yace needs much longer, but then
comes up with a mate one move shorter:
817388866 1:00:40 14.55 12. 1. Rxg7 Qb6 2. Rg6 Qxg6 3. Nxg6+ Kg7 4. Nxf8
Bf5 5. Qe7 h5 6. Rg1+ Bg4 7. fxg4 Kh6 {1271}
822949514 1:01:11 14.95 13++ 1. Rxg7 Qb6 2. Rg6 Qxg6 3. Nxg6+ Kg7 4. Nxf8
Bf5 5. Qe7 Kh8 6. Qxf7 Be6 7. Nxe6 b6 8. Rd7
Nd6 {1351}
827685275 1:01:37 15.95 13++ 1. Rxg7 Qb6 2. Rg6 Qxg6 3. Nxg6+ Kg7 4. Nxe5
Nf6 5. Rg1+ Bg4 6. Rxg4+ Kh8 7. Qxf6+ Kh7 8.
Nxf7 Rfd8 9. Nxd8 h5 {1771}
840501076 1:02:33 20.95 13++ 1. Rxg7 Qb6 2. Rg6 Rg8 3. Rxb6 Nf6 4. Rxf6 Bf5
5. Nxf5 Rg7 6. Nxg7 Kh7
1078767385 1:16:27 Mat10 13t 1. Rxg7 Qb6 2. Rg6 Qxg6 3. Nxg6+ Kg7 4. Rg1 Nf6
5. Nxe5+ Bg4 6. Rxg4+ Nxg4 7. Nxg4 h5 8. Qxh5
Kg8 {HT} {771}
The part of the solution hidden in the HT is: 9. Qh6 Rad8 10. Nf6#
So, this seems to be a problem, solvable by Chest in reasonable time.
