Kira Alekseyevna Zvorykina (September 29, 1919 – September 6, 2014) was a Soviet chess player who spent many years living in Belarus. She was a three-time winner of the Women's Soviet Championship.
Her parents were Aleksey Konstantinovich Zvorykin (brother of Vladimir Zworykin) and Lidiya Terpugova and she was one of seven children. Her immediate and extended family were, in her youth, keen chess players and even held their own private chess tournaments. Buoyed from her success in one of these contests at the age of 16, she entered a school competition and won all of her games.
By 1927 the family had resettled in Leningrad (today, Saint Petersburg). Consequently, the opportunity arose for the young Zvorykina to join the legendary Palace of Young Pioneers' Chess Club where classes were given by rising star Peter Romanovsky, then a Candidate Master. At 17 she became the Leningrad Schoolgirl Champion and also began studying at the Institute of Cinematography. Her time for chess gradually became more limited and it wasn't until 1946 that she began to emerge as an important force in world chess, finishing second in the Leningrad Women's Championship.
Zvorykina married grandmaster and chess trainer Alexey Suetin and together they had a son, Aleksandr, who was born in 1951. Further progress brought Zvorykina up to the pinnacle of Russian Women's chess, as she went on to win the national women's championship outright in 1951, 1953 and 1956. There were also two equal first finishes in 1957 (she lost the tiebreak with Valentina Borisenko) and in 1958 (with Larisa Volpert).
In international chess, there were very few women's tournaments held in the 1950s when Zvorykina was at her peak, but she tied for fourth place at the 1952 Moscow event and beat Anne Sunnucks (+1 =1 −0) in the USSR versus Great Britain Match of 1954. Her greatest success occurred in Plovdiv at the Women's Candidates Tournament of 1959, when victory over a strong field earned her a match with reigning Women's World Champion Elizaveta Bykova for the title. Unfortunately the 1960 match coincided with her mother's terminal illness and this undoubtedly affected her play, resulting in a loss by a 4½–8½ margin.
