🔵 Chess History - Tournaments
🔹 Leningrad 1924/35
🔹 7 December - 2 January
🔹 9th Soviet Chess Champion
🔰 CHAMPION: Grigory Levenfish | 12/19 (+8 -3 =8) |
SHARED WITH: Ilya Rabinovich | 12/19 (+9−4=6) |
📚 The 9th Soviet Chess Championship was played in the city of Leningrad from December 7th, 1934 to January 2nd, 1935. Twenty of the Soviet Union's best chess masters competed in the round robin event, with only one noticeable absence: Mikhail Botvinnik. The winner of the previous two Soviet championships had accepted an invitation to the chess festival held at Hastings at the end of the year 1934, and therefore could not participate as his nation's returning champion. Thus, two of Botvinnik's main rivals at the time were able to succeed at the top of their game in their opponent's absence. They were Fedor Bohatirchuk and Grigory Levenfish, and succeed they did. In the first half of the tournament Bohatirchuk led the field, closely followed by Vladimir Alatortsev, but he fell behind in the second half, allowing Levenfish to finish first, which he shared with Ilya Rabinovich. Bohatirchuk had to settle for third place, tying with Nikolai Riumin, half a point behind the winners. It was the first of two titles that Levenfish would win, while Rabinovich would never win another USSR crown.
