Here is my output:

Kc8 4. Qc6+ Kd8 5. Qa8+ Kc7 6. Qc6+
Kb8 7. Qb6+
11 1:22 ++ 1. b6+!!
11 1:39 4.37 1. b6+ Kxb6 2. Nd7+ Kc6 3. Qa6+ Kxd7
4. e6+ Ke8 5. Qa8+ Qd8 6. g6 Qxa8 7.
g7 Qf3 8. g8=Q+ Qf8 9. Qg2 Qf1+ 10.
Kxf1 Kf8 11. Qf3+ Kg8 12. Qxc3
(4) 11-> 1:48 4.37 1. b6+ Kxb6 2. Nd7+ Kc6 3. Qa6+ Kxd7

(3) 12 2:05 5.07 1. b6+ Kxb6 2. Nd7+ Kc6 3. Qa6+ Kxd7
4. e6+ Ke8 5. Qa8+ Qd8 6. g6 Qxa8 7.
g7 Qf3 8. g8=Q+ Qf8 9. Qg2 Qf2+ 10.
Kxf2 Kf8 11. Qf3+ Kg8 12. Qf7+ Kh8
13. Qf8+ Kh7 14. Qxe7+ Kg6 15. Qxc7
This doesn't look like a great test position. No smarts required. Just very
fast search. If that is the goal, this is ok. If the goal is to find which
