Viacheslav Vasilyevich Ragozin (8 October 1908 – 11 March 1962) was a Soviet chess Grandmaster, an International Arbiter of chess, and a World Correspondence Chess Champion. He was also a chess writer and editor.
Born in the city of St. Petersburg, Ragozin's chess career first came to the fore with a series of excellent results in the 1930s. In the earliest of these, he defeated the respected master Ilyin-Zhenevsky in a 1930 match and was himself awarded the title of soviet master. At Moscow 1935, he won the best game prize for his victory against Lilienthal. At the very strong Moscow tournament of 1936, he beat Flohr and Lasker and came very close to defeating Capablanca, the ever-resourceful ex-world champion scrambling to find a draw by perpetual check at the game's frantic conclusion. There followed a victory at the Leningrad championship of 1936 and second place shared with Konstantinopolsky (behind Levenfish) at the Soviet Championship of 1937. At the 1939 Leningrad-Moscow tournament, he finished third equal, behind Flohr and Reshevsky, but ahead of Keres.
Success continued into the 1940s with first prize at Sverdlovsk in 1942 and a repeat triumph at the Leningrad Championship of 1945. In 1946, he finished outright first at Helsinki and beat Bondarevsky in a match. His greatest achievement in over-the-board chess then followed at the Chigorin Memorial (Moscow) tournament of 1947, where he placed second, a half-point behind Botvinnik, but notably ahead of such luminaries as Smyslov, Boleslavsky and Keres.
By the 1950s, he and most of his generation had been overtaken by the new wave of players emerging from the Soviet chess schools, but Ragozin continued his patronage of the Soviet Championship, competing a total of eleven times, from 1934-1956. Of his rare post-1950 international tournament appearances, his best result came at the 1956 Marianske-Lazne Steinitz Memorial tournament, where he finished second behind Filip, ahead of Flohr, Pachman, Stahlberg and a young Wolfgang Uhlmann.
Throughout his life, he displayed an interest and talent for almost every aspect of the game of chess. For his over-the-board play, he became a grandmaster in 1950 and in 1951 he obtained the title of international arbiter. From 1956–1958, his main focus switched to correspondence chess, where he showed that he was also an expert analyst and theoretician by becoming the second ICCF World Correspondence Chess Champion in 1959 (winning 9 games, drawing 4 games, and losing 1 game). His correspondence chess grandmaster title was awarded the same year.
With Ragozin's wide range of achievements, came a previously unparalleled breadth of expertise and specialised knowledge of the game; a fact that had not escaped the attention of world champion Mikhail Botvinnik. He recognised that Ragozin would make an ideal sparring partner and they played many secret training matches, as Botvinnik prepared for important world championship encounters. Ragozin's style had always been experimental and risky, particularly with regard to the sacrifice of pawns for the initiative. As Botvinnik was attempting to put together a repertoire of solid, reliable openings, it was vital that they were rigorously tested against any latent sacrificial play. Accordingly, many historians attribute Ragozin's contribution as a significant factor in Botvinnik's success.
Ragozin and Botvinnik also teamed up to train for the 1944 Soviet championship. To more or less simulate the noise that would be present in the tournament hall, they practiced with the radio blasting at high volume. Botvinnik won the tournament, whilst Ragozin, placing 13th out of 17, blamed his defeats on the unusual quietness of his surroundings.
His contributions to opening theory mainly concerned the development of systems by which the player of the black pieces could achieve equality in the Queen's Gambit and Nimzo-Indian complexes. In each case, the moves were preparatory to the central pawn push e6-e5.
The QGD Ragozin Defence, typically arrived at via the moves 1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.Nc3 Bb4 (or by transposition) offers black active play from the start and has enjoyed a resurgence in recent times. Ladies' European Champion (2007) Tatiana Kosintseva, Gregory Serper, Varuzhan Akobian and Aleksej Aleksandrov are just four very strong players who have added the opening to their repertoire.
From 1946 to 1955, Viacheslav Ragozin edited the magazine publication Shakhmaty v SSSR, but he also had a career in the construction industry as a civil engineer. He was Vice-President of FIDE from 1950 through 1961.
He died in Moscow while putting together a collection of his best games, which his friends completed for publication in 1964, under the title Izbrannye Partii Ragozina. It contains 74 games spanning his career.
