Georgy Konstantinovich Borisenko (May 25, 1922 — December 3, 2012) was a Soviet correspondence chess grandmaster and chess theoretician.[2] Among the players he trained were Nona Gaprindashvili, Valentina Borisenko (who was also his wife),[2] Viktor Korchnoi, Mark Taimanov,[3] and Timur Gareyev.[2] He became a Russian Master of Sport in 1950 and a Russian Correspondence Grandmaster in 1966. He won the USSR Correspondence Championship twice, in 1957 and 1962, and came in second in 1965.[3] One of his best-known games was played from 1960 to 1963 against Anatoly Rubezov, and is included in multiple anthologies of brilliant chess games.[4] In 1973, David Bronstein described Borisenko as "one of our greatest theoretical experts."[5] In Russia, the Breyer Variation of the Ruy Lopez is known as the "Borisenko-Furman" variation because Borisenko and Semyon Furman were central in bringing it into use in the 1950s.[6] Another line of the Closed Ruy Lopez is also named after him; specifically, the line in the Chigorin Variation which goes 9...Na5 10.Bc2 c5 11.d4 Nc6.[7] [8] His wife Valentina Borisenko was also a chess player and held a Candidate Master title.
