The fourth Candidates tournament was held in 1961 in Vrnjacka Banja, and was utterly dominated by Nona Gaprindashvili of Georgia, who won with ten wins, zero losses, and six draws. She then decisively defeated Bykova with seven wins, no losses, and four draws in Moscow, 1962 to become champion. Gaprindashvili defended her title against Alla Kushnir of Russia at Riga 1965 and Tbilisi/Moscow 1969. In 1972, FIDE introduced the same system for the women's championship as with the overall championship: a series of Interzonal tournaments, followed by the Candidates matches. Kushnir won again, only to be defeated by Gaprindashvili at Riga 1972. Gaprindashvili defended the title one last time against Nana Alexandria of Georgia at Pitsunda/Tbilisi 1975.
