But the threat was eliminated
I was playing in a tournament in Germany one year when a man approached me. Thinking he just wanted an autograph, I reached for my pen, when the man made a startling announcement. 'I've solved chess!' I sensibly started to back away, in case the man was dangerous as well as insane, but the man continued: 'I'll bet you 50 marks that if you come back to my hotel room I can prove it to you.' Well, 50 marks was 50 marks, so I humored the fellow and accompanied him to his room.
