Yes he could have played it out, but I think Ed was curious about this position,
and wondered what would happen after 101.Kf2 which Century 4 wouldn't play.
So he brought it to our attention.

If 101.Nxd5? White loses quickly, after 101. Kf2 White may last longer but would
still lose.

I think he wanted an opinion, what we thought and what other chess engines would
play.

Maybe someone could plug in Kf2 and see how the analysis reads? I think that's
what Ed really is interested in.

Although it's still dead lost for White.
