The first major international tournament after the end of the Second World War took place in Groningen in August and September. It was the anniversary tournament of the Staunton Chess Club, founded in 1871. For the first time ever, a group of Soviet players also took part in a tournament outside the Soviet Union. Before the tournament began, they inadvertently caused a number of organizational problems. Report with video... | Photos: Dutch National Archives (Anefo), unless otherwise indicated.
