National and City, Junior and Senior Championships won by Korchnoi (USSR, Netherlands, Switzerland)
Individual national and city championships, for more details of points and players, please have a look in the section with the chronological year-by-year survey of all 1st Prizes of Viktor Korchnoi:
- USSR champion, Leningrad 1960
- USSR champion, Yerevan 1962
- USSR champion, Kiev 1964/65
- USSR champion, Riga 1970
All four times sole winner, 16 participations.
Remember, it was incredible tough and prestigious to get the (sometimes shared) title of the USSR Championship, only Botvinnik (six titles plus a one-off Absolute Championship) and Tal (also six wins) have more national titles than Korchnoi; with Svidler leading clearly in the post Soviet-Union time, achieving to date incredible seven Russian Championships!
An incredible chess trivia: Former World Champion Vladimir Kramnik played in several National Championships over years, but has never won any - so far.
- Swiss champion, Silvaplana 1982
- Swiss champion, Arosa 1984
- Swiss champion, Silvaplana 1985
- Swiss champion, Grächen 2009,
after rapid play-off vs. IM Ekström
- Swiss champion, Leukerbad 2011,
after rapid play-off vs. GM Gallagher
All five titles alone, eight participations. Viktor Korchnoi was normally busy and of course he was simply too strong, that's why he did no longer participate from the mid-1980s until the late-2000s. Last national title with 80 yrs and 4 mths!!
For the sake of the legality of the things, Viktor Korchnoi also did win the Swiss Champion title in Biel in 1979 but was not awarded it as stateless person by the Swiss Chess Federation. He never complained, it's forgotten.
- Netherlands champion, Leeuwarden 1977
Korchnoi scored eleven wins and two draws (versus Hartoch and versus Langeweg)
