While we’re on the subject... In the mid-1980s Walter Schneider invited me to play in a BDG thematic with a dozen or so old BDG hands. Several had been finalists or semi-finalists in the large BDG World Correspondence Tournament organized by Nick Kampars. It was a great opportunity to meet and compare notes with other longtime BDG fans.
One of my opponents was Karl Hanisch from Germany. Playing black I managed to draw a Lemberger; as white I had better luck with my favorite line in the Teichmann. Christoph Scheerer included this game in his recent book on the BDG.
