Garry Kasparov — World Chess Champion & Greatest of His Era

Early Life and the Soviet Chess System

Garry Kimovich Kasparov was born on 13 April 1963 in Baku, Azerbaijan, then part of the Soviet Union. He showed an exceptional aptitude for chess from an early age and entered the highly structured Soviet chess training system, which at the time produced the strongest players in the world. Under the coaching of Alexander Nikitin and the legendary trainer Mikhail Botvinnik — himself a three-time World Chess Champion — Kasparov developed the deep positional understanding and tactical precision that would eventually set him apart from every contemporary.

He became Soviet Junior Champion and quickly progressed through the ranks of senior Soviet chess. By his late teens he was already competing at the highest international level. In 1980, aged just seventeen, he won the World Junior Chess Championship. His trajectory was unmistakably towards the very summit of the game.

The Karpov Rivalry — The Greatest Matches in Chess History

No account of Kasparov's career can be told without the central drama of his rivalry with Anatoly Karpov. Karpov had held the World Championship since 1975 and was considered the strongest player alive when Kasparov first challenged him in 1984. What followed was an extraordinary sequence of five World Championship matches spanning six years, producing some of the most intensely contested games in chess history.

The 1984 match was abandoned after 48 games without a result — an unprecedented decision by FIDE that generated lasting controversy. Kasparov had clawed back from a near-impossible deficit and was widely seen as gaining momentum when the match was stopped. When the two met again in Moscow in 1985, Kasparov won the championship by five wins to three, becoming, at twenty-two, the youngest World Champion in history.

He defended successfully against Karpov in 1986, 1987, and 1990. The 1986 match in London and Leningrad went to the final game. The 1987 match in Seville ended in a draw with Kasparov retaining his title on tie-break after winning the final game in what is widely regarded as one of the great moments of competitive chess. By the time of the 1990 match in New York and Lyon, Kasparov had established clear dominance, winning 4.5 to 3.5. No two players in chess history have contested more championship matches against each other at the highest level.

Fifteen Years at Number One

From 1985 until his retirement from professional chess in 2005, Kasparov was ranked number one in the world without interruption — a reign of two decades that remains unmatched. He defended his title, expanded his theoretical knowledge, and continued to produce game after game of extraordinary quality. His opening preparation became legendary: he and his team would prepare deep novelties in major variations that opponents had no answer for, often winning games in lines that had been extensively studied for decades.

His style combined the combinational aggression of Mikhail Tal with the systematic positional rigour of Botvinnik. He was equally dangerous in open tactical positions and in long strategic battles, and his ability to switch between these modes within a single game set him apart from players who excelled in only one register. Chess tactics and strategy existed, in Kasparov's hands, as two aspects of a single unified approach.

Deep Blue — Man Against Machine

In 1996, IBM's supercomputer Deep Blue became the first machine to win a game against a reigning World Champion under classical time controls, defeating Kasparov in game one of a six-game match. Kasparov recovered composure and won the match overall by four points to two, restoring the human supremacy that many had feared was already lost.

The 1997 rematch was a different story. IBM had substantially upgraded Deep Blue between the two contests, and the machine won the six-game match three and a half points to two and a half. Kasparov won one game, drew three, and lost two. The decisive loss in game six was particularly painful: Kasparov resigned in a position that many analysts subsequently argued was defensible. He disputed the result and called for a rematch, alleging that some of Deep Blue's moves displayed an understanding beyond what a machine should have been capable of. IBM declined to play again and shortly afterwards dismantled the computer.

The 1997 match remains one of the most significant events in chess history — the moment when artificial intelligence demonstrably crossed a threshold that had been considered out of reach. Kasparov later wrote and spoke extensively about the match and his suspicions about it. Whatever the contested details, the two encounters together constitute a watershed in the relationship between human intelligence and computing power.

Breaking with FIDE

Throughout the 1990s, Kasparov's relationship with FIDE, the international chess federation, deteriorated. In 1993 he and his then-challenger Nigel Short broke away from FIDE to play their match under the auspices of a newly formed Professional Chess Association, leading to a split in the world championship title that persisted for more than a decade. Kasparov continued to hold the Classical World Championship title recognised by most players and commentators as the legitimate succession to the historical title, while FIDE ran a parallel championship of its own.

He lost the Classical World Championship in 2000 to Vladimir Kramnik in a match played in London. Kramnik's preparation of the Berlin Defence against the Ruy Lopez neutralised Kasparov's most potent weapon, and Kasparov was unable to win a single game. It was the end of his fifteen-year reign as undisputed champion.

Retirement, Writing, and Political Activism

Kasparov retired from professional chess in March 2005, announcing that he wished to devote his energy to political opposition in Russia. He became one of the most prominent and outspoken critics of Vladimir Putin's government, co-founding the opposition coalition The Other Russia and subsequently the Anti-Corruption Foundation alongside Alexei Navalny. He relocated to the United States and has continued to write and speak widely about Russian politics, democracy, and authoritarianism.

His literary contribution to chess is substantial. The five-volume series My Great Predecessors, published between 2003 and 2006, is the most thorough and analytically rigorous study of the World Championship lineage ever produced. The books cover every world champion from Wilhelm Steinitz through to Anatoly Karpov, combining deep computer-assisted analysis with Kasparov's own insights as the strongest player of the era. They remain essential reading for any serious student of the game.

Peak Rating and Lasting Legacy

Kasparov's peak FIDE rating of 2851, achieved in 1999, stood as the highest rating ever recorded for fourteen years until Magnus Carlsen surpassed it in 2013. The number reflects not just his superiority over contemporaries but the consistency with which he maintained that superiority across decades. He played over a hundred games at the highest level without a single loss in a classical time-control match during certain periods of his career.

He returned to competitive chess briefly in 2017 for the Saint Louis Rapid and Blitz tournament, performing respectably but not at his peak level. The return was welcomed by the chess world as a reminder of the brilliance that had defined an era. Today, Kasparov is widely regarded as the greatest chess player of all time, a judgement supported by his unbroken dominance, his peak rating, his contributions to chess theory, and the intellectual force of his writing and analysis.

Frequently Asked Questions

Q: How long was Kasparov world chess champion?

Kasparov held the World Chess Championship title for fifteen years, from 1985 when he defeated Anatoly Karpov in Moscow, until 2000 when he lost to Vladimir Kramnik in London. During that entire period he was also ranked number one in the world on the FIDE rating list without interruption, a sustained dominance of professional chess unmatched in the modern era. If one includes the period from his 1985 victory to his 2005 retirement from professional chess, he spent two full decades as the world's leading player by rating.

Q: Did Kasparov lose to Deep Blue?

Kasparov won the first match against IBM's Deep Blue in 1996, taking the six-game contest four points to two. However, in the 1997 rematch against a significantly upgraded version of the machine, Deep Blue won by three and a half points to two and a half, making it the first computer to win a match against a reigning World Champion under classical time controls. Kasparov won one game, drew three, and lost two in the 1997 match. He disputed the result and requested a rematch, but IBM declined and subsequently dismantled the computer.

Q: What is Kasparov's peak chess rating?

Kasparov's peak FIDE rating was 2851, reached in July 1999. This was the highest rating ever recorded at the time, and it remained the all-time record for fourteen years until Magnus Carlsen surpassed it in 2013. The rating reflects not only Kasparov's extraordinary strength but the consistency with which he maintained a large gap over all other players in the world across the peak years of his career.

Q: Did Kasparov and Karpov play each other?

Kasparov and Karpov contested five World Championship matches between 1984 and 1990, the most matches any two players have ever played against each other at the World Championship level. Their rivalry is considered the greatest in chess history. The 1984 match was abandoned after 48 games; Kasparov won the 1985 match to claim the title; and he successfully defended against Karpov in 1986, 1987, and 1990. Beyond the championship matches, they also played numerous games in other elite tournaments, accumulating a record that showed Kasparov with a positive score overall but Karpov always competitive.
