My program has always solved WAC 8 easily. But last night I noticed the latest
version chose Nf7+ instead of Rf7. I looked at the position with Crafty 16.18,
and it gives mate in 7 after Rf7. After Nf7+, Crafty gives mate in 10 on ply 12,
so this value may not be trustworthy.

Can anyone look at the position and find out how far Nf7+ really is from mate?
