It appears that b7 is a mate in 18.
19-> 1:34 Mat18 1. b7 Rg5+ 2. Kc6 Rg6+ 3. Kd5 Rg5+
4. Ke6 Rg6+ 5. Kf5 Rg1 6. Rf8+ Kxb7
<HT>
It first found mate in 23, then 21, 20, and 18. So it could go down again, but
I doubt it.
However, Ka5 seems to be a mate in 15, and Kc5 a mate in 17.
15-> 1:14 Mat15 1. Ka5 Rg1 2. Rf8+ Kb7 3. g8=Q Ra1+
4. Kb4 Rb1+ 5. Qb3 Rxb3+ <HT>
15-> 1:06 Mat17 1. Kc5 Rg5+ 2. Kb4 Rg4+ 3. Ka5 Rg1
4. Rf8+ Kb7 5. g8=Q <HT>
