I agree Ke4 is an alternate solution. I will add it as an alternative "best
move".

Crafty fails high with Nef6+ at ply 15 after 14 minutes on my Athlon XP2500+,
but then changes to Ndf6+:

It looks like Ndf6+ and Nef6+ are both winning here and should be listed as
alternate solutions (instead of Nxc7).
