VIKTOR KORCHNOI
(born Mar-23-1931, died Jun-06-2016, 85 years old) Russia (federation/nationality Switzerland)
PRONUNCIATION:
[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 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 Match (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 Senior Championship, scoring 9-2. 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. He died in Wohlen, Switzerland on June 6, 2016, aged 85.

Kibitzer's Corner
< Earlier Kibitzing  · PAGE 33 OF 101 ·  Later Kibitzing>
Mar-29-06  Marvol: <vesivialvy93> I think a better reason for all the praise of Karpov and Korchnoi by Kasparov is that they were actually very good chess players, as proven by their achievements. Not just to prove himself (he doesn't really need to, does he?)
Mar-29-06  Jim Bartle: Reading the Kasparov interview at chesscafe.com, K certainly seems sincere in his high opinion of the other K's.

He did say, though, that he was going to do a book of "anecdotes," not focusing specifically on games, where he hints that there will be material which doesn't reflect so well on Karpov.

  Ron: It was a pleasure to read Korchnoi's letter of support for The Right Move Campaign, which can be seen at their website. And I first came across this quote which is now one of my favorites:

Korchnoi says: "If a player believes in miracles he can sometimes perform them."

Apr-01-06  Jim Bartle: Here's the address: http://www.rightmove06.org/index.ph...

Lots of nice photos of Korchnoi throughout his career.

Apr-03-06  diagonal: Thanks for information & link with lots of Victor's bio notes. Interesting and very clear statement by Korchnoi, supporting Bessel Kok and the Right Move campaign for the return to "a school of democracy" (quote from V.K.) for FIDE presidency - I would add - in the line of Olafsson Fridrik, Euwe and predecessors.

The (rather) long-term mission and vision "A FIDE for the 21st century" from Bessel Kok and his ticket members (among them Seirawan) sounds plausible; of course, a reunification with ONE and ONLY World Chess Champion - as already aimed e.g. with the so-called Prague Agreement in 2002 - is prior for this sport, especially for the mass-media.

Apr-03-06  suenteus po 147: Question for those who know: How did Korchnoi qualify for the Leningrad Interzonal in 1973?
Apr-03-06  suenteus po 147: Follow up question: If there was a zonal tournament Korchnoi qualified from, what was it?
Apr-03-06  Benzol: Peter, good questions. Unfortunately I'm not sure of the answers. However, I can tell you that it wasn't the 1973 USSR Championship. The Leningrad Interzonal took place in June and the Championship wasn't until October. This was also the first time that there were two interzonals with the other one being in Brazil. The Leningrad event in my opinion was the stronger of the two.
Apr-03-06  suenteus po 147: <Benzol> Was there a USSR Championship in 1972?
Apr-03-06  Gypsy: Not that I know for sure, but my educated guess is that Korchnoi qualified by being the finalist (against Petrosian) in the previous cycle of candidate matches.
Apr-03-06  suenteus po 147: <Gypsy> Wouldn't that have seeded him directly into the 1974 Candidates, though? Or was he only a semi-finalist and not a finalist? I thought Fischer beat Petrosian to become Spassky's challenger.
Apr-03-06  suenteus po 147: I have a strong suspicion that <Resignation Trap> might know the answer to all of this.
Apr-03-06  Benzol: <Was there a USSR Championship in 1972>

Yes, it was won by Tal with Tukmakov in 2nd place. Neither Korchnoi nor Karpov played in the event so how they qualified remains unknown to me, but I think you're right about <Resignation Trap>.

Apr-03-06  suenteus po 147: <Benzol> It might be that <Gypsy> is right, that Korchnoi was seeded into the interzonal by grace of being just a candidate in 1971. If so, how far do I have to go back now? :|

  keypusher: Yes, the 1972 Soviet championship, the 40th, was a Zonal, and Tal qualified by winning it. Karpov was given a pass to the Interzonal because he was the World Junior Champion (not sure this ever happened for anyone else!). I don't know how Korchnoi qualified but I assume it was because he was a semifinalist -- that would explain Larsen's presence in Leningrad too.
Apr-03-06  Benzol: <Gypsy> might be right but how did Karpov qualify? The Alekhine Memorial maybe?
Apr-03-06  Benzol: <keypusher> Thanks.
Apr-03-06  suenteus po 147: Okay, here's what I have so far from online research: Assuming <Gypsy>'s suggestion is correct, Korchnoi was seeded into the '73 interzonal by grace of being a semi-finalist in the '71 candidates (he lost to Petrosian, I think). He qualified for '71 by being the finalist Spassky defeated in '68 for his second chance at Tigran. Korchnoi qualified for the '68 candidates by way of a three way tie for second along with Geller and Gligoric at the Sousse Interzonal in 1967. There the trail stops. How did Korchnoi qualify for THAT interzonal?

  Pawn and Two: <suenteus po 147>

Korchnoi qualified for the 1974 Candidates matches by finishing I/II with Karpov at the Leningrad Interzonal in 1973. R. Byrne also qualified by finishing III at Leningrad.

Mecking, Portisch & Polugaevsky qualified for the 1974 Candidates by winning at Petropolis 1973. Portisch & Polugaevsky had tied with Geller for II/IV and were successful in the playoff.

Spassky and Petrosian were automatically ceded into the Candidates matches.

  Pawn and Two: <suenteus po 147>

In the 1968 Candidates, Larsen (I); Korchnoi, Geller & Gligoric (II/IV) and Portisch (V) qualified from the 1967 Sousse Interzonal.

Spassky and Tal were automatically ceded as Candidates.

Reshevsky, Stein and Hort had to play-off for the final qualifying spot. After a drawn play-off, Reshevsky was placed sixth on tie-break and became the final Candidate.

The Reshevsky, Stein, Hort play-off was a great tragedy for Stein. With only two games remaining, Stein led with 4 points out of 7, Reshevsky was next with 3.5 out of 7(all draws) and Hort trailed with 2.5 out of 6.

Stein had to play Hort first, then Hort and Reshevsky would play the final game.

Stein had White and was aggressive in the opening. However, Hort succeeded in gaining counterplay. Suddenly Hort offered a draw! A draw would put Stein a full point ahead of Reshevsky with only one game remaining. But Stein decided to continue playing and lost. Then Reshevsky and Hort drew their game and all three players had 4 points each.

Reshevsky was awarded the final Candidates spot on tie-break without winning a single game in the play-off!!

Unfortunately this turned out to be Stein's last chance to be a Candidate.

  keypusher: <suenteus po> <How did Korchnoi qualify for THAT interzonal?> It turns out to be a pretty complicated story! The 34th Soviet Championship was held in Tbilisi in 1966/67. It was a Zonal and the top 4 finishers qualified for Sousse. And the top finishers were: 1. Stein 13/20, 2. Geller 12 1/2,...3-5. Gipslis, Korchnoi, Taimanov 12. Yes, a three way tie for two slots.

So, a three-way play-off was held in Talinn in 1967. Taimanov had four draws, and Giplis and Korchnoi beat each other, leaving everyone with 2/4 scores...and Taimanov was eliminated on the grounds that he had an "inferior [Berger?] coefficient" (maybe someone more proficient than I am in tiebreaks can explain that) in the championship tournament. And that's how Korchnoi got to Sousse.

(This was taken from OMGP V at 60-61.)

That's a terrible story about Stein. The 37th Soviet championship in 1969 was also a Zonal...but he finished sixth. And Tal didn't even reach 50%.

  Open Defence: the candidates through the 1960s can be dubbed the Stein Tragedies
Apr-04-06  suenteus po 147: <keypusher> Thank you for the complete history. Complicated indeed!

<Open Defence> A couple of kibitzers on this site have commented that Stein was one of the greats never to become world champion and I'm starting to get a clearer picture why that is.

Apr-04-06  suenteus po 147: <Pawn and Two> Thank you for the story about Stein, as terrible for him as it was.
