Kira Zvorykina was one of the strongest female players in the world during the 1950s and early 1960s. She won the Soviet Women’s Chess Championship three times (1951, 1953, 1956) and tied twice but lost in playoffs (1957 and 1958). Her greatest triumph was winning the 1959 Women’s Candidates Tournament, which qualified her to play a match for the Women's World Chess Championship against Elizaveta Bykova. Zvorykina lost the match 4 ½-8 ½. She twice represented the Soviet Union in Chess Olympiads, winning team gold on both occasions while scoring an undefeated 17 ½ from 20. Zvorykina’s book Vri︠a︡dkh shakhmatnoĭ gvardii (In the Ranks of the Chess Guard, 1984) recounts highlights from her career.
