• A Game That Outlasted the Day (5)

  If a game could have been legally drawn dozens of moves earlier, why was it played on? Why were obvious draw claims never made, even when repetitions were plainly visible?

• A memorable upset: Wolfgang Uhlmann beats the world champion at the 1962 Varna Olympiad

  Winning against the reigning world champion is always difficult. The first German player to achieve this feat after the Second World War was Wolfgang Unzicker, for many years the number one player in the Federal Republic of Germany. At the 1961 European Team Championship, he outplayed the then world champion Mikhail Botvinnik. Wolfgang Uhlmann, for many years the number one player in the GDR, was not to be outdone. In 1962, at the Chess Olympiad in Varna, he defeated Botvinnik - though not quite as convincingly as Unzicker had done a year earlier. | Image: Wolfgang Uhlmann in 1970 | Photo: Rob Mieremet, Anefo
