FIDE player card for Viktor Korchnoi

(born Mar-23-1931, 84 years old) Russia (federation/nationality Switzerland)
[what is this?]
Viktor Lvovich Korchnoi was born in Leningrad, USSR. His father taught him chess when he was seven years old. He won the Soviet Championship four times: USSR Championship (1960), USSR Championship (1962), USSR Championship (1964/65) and USSR Championship (1970). He made eight appearances in the world championship candidates cycle. He reached the Spassky - Korchnoi Candidates Final (1968), but failed to beat Spassky. In the next cycle he won his quarterfinal Korchnoi - Geller Candidates Quarterfinal (1971), but lost his semifinal match to Tigran Vartanovich Petrosian. He made it to the Karpov - Korchnoi Candidates Final (1974), but lost.

Korchnoi defected from the USSR in 1976, and two years later he finally managed to win the Candidates and qualify for the Karpov - Korchnoi World Championship Match (1978). Trailing late with just two victories to Karpov's five, Korchnoi staged a comeback, winning three games to level the score at 5-5. However, Karpov then won the final game, thereby taking the match and retaining the crown. Korchnoi qualified again for the Karpov - Korchnoi World Championship Rematch (1981), but was beaten 6-2. In the next Candidates cycle he was beaten by the rising young Soviet star Garry Kasparov. He continued to play at a very high level throughout the 1980s and 1990s, though he never contended for the world title again. He did, however, capture the 2006 World Seniors' Championship, scoring nine points out of eleven games. Though never World Champion himself, Korchnoi defeated nine players who at some time held the title: Petrosian, Spassky, Karpov, Mikhail Botvinnik, Vasily Smyslov, Mikhail Tal, Robert James Fischer, Kasparov and Magnus Carlsen.

After defecting, Korchnoi settled in Switzerland, which he represented at Olympiads and other international events. He was ranked in the top 100 on the FIDE world rating list as late as January 2007 (aged 75), the oldest player ever so ranked.

Korchnoi suffered a stroke in December 2012, but returned to competitive chess beginning in 2014.

Jun-25-15  ughaibu: Korchnoi's results as black, using the KID, are very slightly better than his results with white.
Premium Chessgames Member
  Caissanist: How many games were you able to find with Korchnoi having black in the KID? I could only find four here at Chessgames.
Premium Chessgames Member
  Tomlinsky: Viktor Korchnoi with KID as Black:

Wins = 11
Draws = 10
Losses = 3

Jun-25-15  ughaibu: My comment above involved mistaking his white draws and losses. This morning's guess is that the white result is 6.7% higher. I wonder how his performance varied, black vs. white, in other openings. Who wants to do a few?

  diagonal: Marvelous Photograph of <Viktor Korchnoi> at the third <Pegasus Summit in Dresden 2014>, the meeting of chess grandmasters 75+ years young :)

Viktor Lvovich, the Inimitable and Infatiguable. The iron man of chess, who played and beat grandmasters of five generations, from <Levenfisch> (born 1889) and <Lilienthal> to <Carlsen> and <Caruana> (born 1992), with a persistant search for new ideas and truth at the chess board, master of aggressive counter-attacking, full of fantasy, with a unique willingness to enter double-edged, unbalanced positions in a fresh style and competitive longevity. What an immense Gallery of Opponents:

Jul-03-15  HeMateMe: The above article mentions that VK has beaten the last nine undisputed world champions, from post WWII to the present (he has beaten Magnus Carlsen). I wonder about the 'disputed' world champions? Does he have wins against Topalov, Kramnik and Anand?
Jul-03-15  Lambda: Kramnik and Anand, disputed?

Topalov different from all the other toy FIDE champions?

Jul-03-15  HeMateMe: I don't think Kramnik and Anand are 'disputed,' but they aren't given the full respect that the other champions are given, in this article.

I never considered Topalov world champion just because he won some B.S. consolidating tournament, set up to clean up the mess made by Kasparov's decision.

Jul-03-15  Troller: No classical wins against Anand (surprising) or Kramnik (less surprising) according to cg database. But he did beat Topalov first time around: Korchnoi vs Topalov, 1991
Jul-03-15  ughaibu: According to the database Korchnoi has never beaten either Kramnik or Anand, but he has beaten Topalov. Naturally the article doesn't mention Topalov, as he was never world champion.

  diagonal: quote from the site: <Viktor Korchnoi is the only man on earth beating every of the eight non-disputed post-war II world chess champions from Botvinnik to Kasparov in a regular classical tournament or match game> then the these eight World Champions are mentioned - plus Carlsen (commonly regarded as the 16th World Chess Champion)

It is also mentioned (quote) <Korchnoi is in lifetime scores behind 44-years younger Kramnik, and clearly behind Anand (no wins)>

Both statements are imo correct. And of course, Anand and Kramnik are non-disputed World Chess Champions! That's why they are not listed in the Gallery of beaten champs by Korchnoi.

The site mentions, that there are two other Greats, who have also beaten nine undisputed World Chess Champions: <Keres> (widely known), and <Beliavsky> (mostly forgotten or not realized).

Korchnoi beat Topalov once at Las Palmas in earlier years, but Topalov (undoubtedly a strong tournament player somehow in the line of Larsen) is in generally not considered as an undisputed World Chess Champion, he was FIDE Champion during the schism, that's why is not counted here.

Some commentators or players, eg. Nigel Short who was at least co-maker of the chess world split in 1993, might possibly in their own interest also count the FIDE K.-O. (some would say: Lottery) Champions during the schism (Khalifman, was the first of these people, as world no. 44 or 46 in ELO list, then Ponomariov, Kasimdzhanov, and Topalov - Anand and Karpov claimed the FIDE title at some point too, but naturally they reigned as well as longtime undisputed World Chess Champions).

If Topa-Pono-Khalif-Kasim are counted, then only players of their age and era could benefit from beating them in a phase of title inflation and near yearly variety of cup holders. I regard <Magnus Carlsen> as <16th World Chess Champion> in modern history.

Premium Chessgames Member
  Tomlinsky: <diagonal> Why would it be in the interests of Short, and by extension Kasparov, to claim that Khalifman, Ponomariov and Topalov are legitimate World Champions when the title they held was arranged by the "opposition", FIDE?
Premium Chessgames Member
  Ron: Korchnoi is a killer of the King's Indian Defense. One of his favorite opening systems is this: Repertoire Explorer: Viktor Korchnoi (white)

White's strategy is clear. Attack on the Queenside, defend your Kingside. Notice that White's two bishops are placed to both support a queenside attack and defend the Kingside. I've used this system in offhand games with good results.

Premium Chessgames Member
  diagonal: <Tomlinsky> sorry for answering late: Today, Short rarely speaks about the schism in opposition to the FIDE he & Kasparov provoked in 1993, and the mess they caused.

Nigel Short in an interview or eg. Judit Polgar in one of her recent published books - as well some media recipients - tend to counting Kasim, Khalif & Co. as Chess World Champion, pimping up the number of beaten Champions. An example: "Judit Polgar has defeated nine World Champions", Quote from

In historical comparisons, some of these FIDE lottery winners, were relatively weak (still on a high level, of course), beaten by many players wtihin a short time. Don't forget, Kasimdzhanov never ever was a top-ten player, not a single month, neither FIDE nor SONAS. Khalifman was about number forty something in the ELO rating list when winning that title. Kasparov clearly not count them.

It's all about the definition of <undisputed>: I regard Magnus Carlsen as the 16th World Chess Champion in modern history following Anand, Kramnik, Kasparov, Karpov, Fischer, Spassky and predecessors.

According to this line, Beliavksy (often forgotten), Korchnoi and Keres have beaten nine World Chess Champions in classical games.

Premium Chessgames Member
  Tomlinsky: <diagonal> Not a problem. Yes, I understand the thrust of what you are saying and thought your post made some good factual points only to be ruined by basing the final sloppy paragraph wholly on a 'might possibly'. I don't even disagree with the points made but randomly throwing your gut feeling on what GM Short may, or may not think, on the subject adds no value to them at all as far as I can see.
Jul-22-15  savagerules: When Korchnoi was in his mid 70s a few years back he beat a twenty something IM with White in a Benko gambit and it lasted around 60 moves or so and when he shook hands at the end of the game he sarcastically told the IM "Why did you give me a pawn at move 3?" The IM was all miffed at Korchnoi for this and was saying Korchnoi was a bad sportsman and bad human being for doing this. lol The IM was just mad for getting beat by a 76 year old most likely.
Premium Chessgames Member
  perfidious: <savagerules> Recall such a story--difference was, Korchnoi beat up on his beloved whipping boy, the KID and had some smarmy remarks postgame.
Premium Chessgames Member
  tamar: I recall reading about the KID at Gibraltar, but it never found its way into our database.
Premium Chessgames Member
  offramp: Korchnoi's style reminds me of a gifted child who has been given a one hour chess lesson by Botvinnik and a two hour chess lesson by Smyslov then told to go out there and give it his best shot.
Premium Chessgames Member
  RookFile: If that's the case, sign me up for those lessons too.
Sep-22-15  siggemannen: Nice kill by Korchnoi in that KID (or more of a modern)-game
Sep-29-15  7he5haman: I saw Korchnoi once. He was giving a simultaneous and the London Chess Classic a few years ago. I must've caused some disturbance, because he gave me such a stern look!
Premium Chessgames Member
  offramp: Three huge King's-Indian-Annihilators are Petrosian, Kramnik and Kortschnoi.

It's odd in a way because their styles are all dissimilar.

Oct-18-15  PJs Studio: I've read Kortchnoi is a stern GM, but hasn't he earned enough through age, accomplishment and certain difficulties with the government he expatriated? I've always considered him as Sisyphus - Disrespected yet undaunted.

If I lost to him with the Benko and he asked me "Why did you give me a pawn on move three?" I'd laugh my ass off. Some players are so full of themselves.

  Big Pawn: <Korchnoi suffered a stroke in December 2012, but returned to competitive chess beginning in 2014.>

That's such great news! What a tough old bugger!
