🔷 Chess History - Tournaments
🔹 Moscow 1949
🔹 17th USSR chess championship
🔹 October 16 - Nevember 20
🔹 CHAMPION: Vasily Smyslov |13/19 (+9 -2 =8) |
Shared with David Bronstein | 13/19 (+8 -1 =10) |
🔰 The 17th USSR chess championship took place in the Soviet capital of Moscow from October 16th to November 20th, 1949. Twenty of the Soviet Union's best grandmasters and masters qualified or received invitations to participate in the round robin event.
❗️ Twelve players qualified from semi-final tournaments held earlier in the year:
Igor Bondarevsky, Mark Taimanov, and Grigory Levenfish qualified from Leningrad; Vladas Mikenas, Alexey Sokolsky, and Semyon Furman qualified from Vilnius; Lev Aronin, Grigory Goldberg, and Victor Liublinsky qualified from Moscow; and Efim Geller, Tigran Petrosian, and Ratmir Kholmov qualified from Tbilisi. Bondarevsky could not attend the final, so he was replaced by Leningrad fourth place Nikolai Kopilov.
❗️ The eight remaining players were invited to fill out the field were:
David Bronstein and Alexander Kotov as returning champions from the 16th championship; previous Soviet champions Andre Lilienthal and Paul Keres; and four previous final participants Isaac Boleslavsky, Salomon Flohr, Viacheslav Ragozin, and Vasily Smyslov.
🔰 This tournament saw two of Mikhail Botvinnik 's greatest rivals finish shared first with thirteen points out of nineteen rounds. It was Bronstein's second consecutive Soviet crown, and his last. He would face Botvinnik two years later for the world crown, coming closer than anyone else to being world champion without succeeding. While this championship was Smyslov's first and last Soviet crown, he too would go on to face Botvinnik, but unlike his fellow shared first, he would defeat Botvinnik in their second of three encounters, earning the highest of all chess honors: the champion of the world.
