A new walk on an old battlefield

The photo of old BDG friends which I posted recently induced me to review the battle between Diemer and Gunter Müller, Biel 1975, which Gunter annotated for BDG WORLD 25 in December 1986. I’ve retained Gunter’s original notes and augmented them with a few of my own (indicated with ***), assisted by computer analysis and tablebases which were of course not readily available almost a quarter century ago.
