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.
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.
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. 
Since the 1991 reunification of Germany, the Berlin championships are again held as single events.
