πΉ Efim Bogoljubov |7/9 (+6 -1 =2) |
π° On occasion of the 60th birthday of Bernhard Kagan, the "Freie Schachvereinigung Berlin" ( Free Chess Association Berlin) arranged a small tournament with 10 participants. The field was noticeably strengthened by the participation of Efim Bogoljubov, who had returned to Germany after a two years stay in Russia, and also Rudolf Spielmann. The favorite Bogoljubov won in the end, despite a bad start with a loss to Ernst Gruenfeld in round 2. Spielmann disappointed a little. The tournament was sponsored by Viktor Tietz.

The tournament, from 17.-29.November 16-28. Nov, according to the tournament book held in Berlin at CafΓ© Zielka, is the third international championship tournament in Germany after Dresden and Hanover. Once again, General Manager Bergmann (Dresden) of the cigarette factory Bergmann AG proved itself by earning the 1st prize of 1000 M as a deserved chess patron. The arrangement of the tournament met Master Mieses, the tournament management had taken over the well-known and proven V.Tietz (Carlsbad).
The tournament was particularly interesting because Bogolyubov after a long break again in the barriers. He was of course the favorite. But it almost seemed as if he had lost his strength due to the long game break because he started with a close draw and a loss. But then he won all matches except the last against Rubinstein, which he drew, which was enough for him to secure victory. Rubinstein had decided bad luck that he was second only despite a good game because he just lost against the bottom of the table a game.
