Berlin_City_Chess_Championship
The Berlin Chess Championship is an annual chess tournament in Germany. The first unofficial Berlin Chess Championship was held in 1853, and Jean Dufresne won a match against Max Lange.[1] Since 1904, official Berlin championships have taken place. The first event was won by Horatio Caro, followed by Ossip Bernstein, Rudolf Spielmann, Wilhelm Cohn, Benjamin Blumenfeld, etc.[2][3]
As a result of the post-war division of the city into East Berlin and West Berlin, from 1953 until 1990 two separate championships were held.[4] Since the 1991 reunification of Germany, the Berlin championships are again held as single events.[5]
