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. Terry
