<Dortmund 1979: On the day of the Nikolac-Bohmfeldt game, the round started an hour earlier than usual. A few minutes after the start of the round all players had turned up except for Bohmfeldt. After half an hour Nikolac started to look worried. A win by default would not count towards his norm, and the norm would be mathematically impossible if Bohmfeldt were automatically defaulted for being more than an hour late. Nikolac waited nervously outside the tournament hall, and when he spotted Bohmfeldt in the distance he practically dragged the astonished German into the tournament hall. He was just in time - five minutes more and it would have been too late. Nikolac won the game easily.>
