The given best-game solution is not optimal: Black can delay mate for another move to give a forced win in 11 ply rather than in 9 ply.
Optimal is: N4 n5 N6+ k7 R4 as given,
but Black can delay mate with ... n3+, rather than ...k6.
The remaining moves are then: K2 n5 N8 k8 R5#.
Perhaps your minimax code doesn't include moves-to-mate in the move score? |
