Garry Kasparov (born 13 April 1963) is a Russian chess grandmaster, former World Chess Champion, and writer. Widely regarded as one of the greatest chess players of all time, he held the FIDE world number‑one ranking for 255 months—the longest of any player—and was the undisputed world champion from 1985 to 1993. Kasparov revolutionized chess opening theory with his deep preparation and aggressive style, and his matches against Anatoly Karpov and the IBM supercomputer Deep Blue became iconic moments in chess history. After retiring from professional chess in 2005, he has worked as a chess commentator, author, and promoter of the game, while also engaging in non‑chess writing and public speaking on strategy and decision‑making.
1 Early life and introduction to chess
1.1 Family background and early education
Garry Kimovich Kasparov was born in Baku, Azerbaijan SSR, Soviet Union, to a Jewish father, Kim Moiseyevich Weinstein, and an Armenian mother, Klara Shagenovna Kasparova. His father died when he was seven years old, and his mother raised him. She later encouraged him to adopt her surname, Kasparov, which was also intended to avoid potential anti‑Semitic prejudice. Kasparov showed exceptional intellectual abilities from an early age, learning to read before age four and solving chess puzzles at five. He was enrolled in a prestigious school for gifted children in Baku, where he excelled in mathematics and languages.
1.2 First chess coaches and junior successes
Kasparov’s introduction to chess came when his parents solved a chess problem in a newspaper; he quickly mastered the rules. At age six, he joined the Baku Palace of Pioneers chess club. His first coach was Oleg Privorotsky, who recognized his prodigious talent. By age nine, Kasparov was training under former Soviet champion Mikhail Botvinnik, who took him into his chess school. At age twelve, he won the Soviet Junior Championship, and at thirteen he became the youngest ever FIDE Master. In 1978, he won the World Youth Chess Championship (under‑16 category) and earned the title of International Master.
2 Rise to world championship
2.1 Early grandmaster career (1978–1984)
Kasparov achieved the grandmaster title in 1980, at age 17, after finishing second in the World Junior Championship. That year he also made his debut in the Soviet Chess Championship, tying for first place. In 1981, he won the Soviet Championship outright at age 18, becoming the youngest winner in history. His rapid ascent continued: he qualified for the World Championship Candidates cycle in 1982 and defeated Alexander Beliavsky, Viktor Korchnoi, and Vasily Smyslov in the matches to earn the right to challenge reigning champion Anatoly Karpov.
2.2 1984–85 World Championship match vs. Anatoly Karpov
2.2.1 Abandoned marathon match and controversy
The first match between Kasparov and Karpov began on 10 September 1984 in Moscow. It was played as the first to win six games, with draws not counting. Karpov took a commanding 5–0 lead after three months, but Kasparov then adopted a defensive strategy, drawing game after game and eventually winning two games to bring the score to 5–2. After 48 games and nearly five months, FIDE president Florencio Campomanes controversially terminated the match on 15 February 1985, citing concerns for the players’ health. The decision sparked widespread criticism, with many accusing the Soviet chess establishment of favoring Karpov.
2.2.2 Second match and Kasparov’s victory
A new match, limited to 24 games, was scheduled for later in 1985. Kasparov won game 16 with a brilliant attacking display, and after a series of decisive games, he secured a 13–11 victory (with 3 wins, 11 draws, 2 losses) on 9 November 1985. At age 22, he became the youngest undisputed world champion in history, a record that still stands.
3 World Champion years (1985–2000)
3.1 Defenses of the title against Karpov (1986–1990)
3.1.1 1986 match in London and Leningrad
The first defense was scheduled for 1986, split between London and Leningrad. Karpov took an early lead, but Kasparov rallied, winning games 17, 18, and 22 to clinch a 12.5–11.5 victory. The match featured some of the most intense and creative chess ever seen at the world championship level.
3.1.2 1987 and 1990 rematches
In 1987, Karpov pushed Kasparov to the limit in Seville. With one game remaining, Kasparov trailed by a point but won the final game to tie the match at 12–12, thus retaining the title under the rule that the champion kept the crown in a drawn match. The 1990 match, held in New York and Lyon, was another nail‑biter. Kasparov prevailed with a 12.5–11.5 score, defeating Karpov for a fourth consecutive world championship match.
3.2 Break with FIDE and formation of the PCA
3.2.1 1993 World Championship vs. Nigel Short
In 1993, rivalries within FIDE led Kasparov and his challenger Nigel Short to break away from the organization and form the Professional Chess Association (PCA). They staged their own world championship match in London, which Kasparov won convincingly 12.5–7.5. FIDE immediately stripped Kasparov of its recognized title, creating a split in the world championship that lasted until 2006.
3.2.2 PCA era and further title defenses
Kasparov defended his PCA title in 1995 against Viswanathan Anand in New York, winning 10.5–7.5 after a spectacular victory in game 13. He later defeated Alexei Shirov in 2000 (match for the PCA title, though by then the PCA had dissolved). However, in 2000, Kasparov lost the classical world championship (now reunited under the Braingames banner) to Vladimir Kramnik, 8.5–6.5. Kasparov never regained the classical title but remained the world number one by rating until his retirement.
4 Playing style and contributions to chess theory
4.1 Attacking style and strategic depth
Kasparov was renowned for his aggressive, dynamic style, combining deep tactical calculation with long‑range strategic planning. He often sought to unbalance the position early, creating rich complications that tested opponents’ defensive skills. His ability to calculate variations many moves ahead, coupled with an exceptional memory and relentless energy, made him a fearsome competitor.
4.2 Opening innovations
4.2.1 The Kasparov Variation in the Sicilian Defense
One of Kasparov’s most famous contributions is the Kasparov Variation in the Sicilian Defense (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nb3 Be6), which he introduced in the 1990s. This line aimed to challenge the Najdorf and Scheveningen structures with an early f3, preparing a kingside attack. It became a major weapon for White and influenced opening theory for years.
4.2.2 Contributions to the Queen’s Gambit and King’s Indian
Kasparov also made significant contributions to the Queen’s Gambit (especially the Tartakower and Meran variations) and the King’s Indian Defense, where he favored sharp lines like the Mar del Plata variation. His preparation often involved deep analysis of obscure sidelines, forcing opponents onto unfamiliar ground.
4.3 Legacy in chess literature and database use
Kasparov was a pioneer in the use of computer databases for opening preparation. He collaborated with IBM and other programmers to create one of the first comprehensive chess databases, ChessBase, which revolutionized how players studied openings. He also authored several influential books, including the multi‑volume *My Great Predecessors* series, which detailed the careers of past world champions with deep analysis of key games.
5 Landmark matches against computers
5.1 1996 and 1997 Deep Blue matches
5.1.1 Game 1 of the 1996 match and Kasparov’s win
In February 1996, Kasparov played a six‑game match against IBM’s Deep Blue computer in Philadelphia. He won the match 4–2 (with a famous win in Game 1, where he sacrificed a pawn for a devastating attack). This was the first time a world champion defeated a computer in a match setting. However, the computer’s performance impressed observers, and Kasparov commented that the machine had shown moments of “human‑like” play.
5.1.2 1997 defeat and aftermath
The rematch in May 1997, played under standard time controls in New York, ended in a 3.5–2.5 victory for Deep Blue. Kasparov won Game 1, but lost Game 2—a stunning defeat where he made an uncharacteristic blunder. After three draws, Kasparov lost Game 6 when he appeared to make a miscalculation, leading to immediate resignation. The result was front‑page news worldwide and sparked debates about artificial intelligence. Kasparov later accused IBM of cheating, alleging that the team had accessed human grandmaster advice during the games. IBM denied the accusations and retired Deep Blue afterward.
5.2 Later computer engagements (2003 vs. Deep Junior and X3D Fritz)
In 2003, Kasparov played two matches against advanced chess engines: one against Deep Junior (drawn 3–3) and one against X3D Fritz (also drawn 3–3). These matches, played under more controlled conditions, demonstrated that the top human players could still hold their own against the strongest computers, though the engines’ rapid improvement was clear.
6 Retirement and post‑chess activities (2005–present)
6.1 Writing and publishing
6.1.1 Autobiographical works and chess books
Kasparov has authored numerous chess books, including *Kasparov Teaches Chess* (1986), *The Test of Time* (1986), and the acclaimed *My Great Predecessors* series (2003–2006). He also wrote *Kasparov: The Chess Master and the Computer* (1991) and *How Life Imitates Chess* (2007), which blends chess anecdotes with leadership advice.
6.1.2 Strategy and business books
Beyond chess, Kasparov has written on strategy, decision‑making, and technology. His book *Winter Is Coming: Why Vladimir Putin and the Enemies of the Free World Must Be Stopped* (2015) addresses political topics, but falls outside the scope of this article. *Deep Thinking: Where Machine Intelligence Ends and Human Creativity Begins* (2017) examines the lessons of his matches against computers.
6.2 Chess coaching and exhibition matches
Since retiring, Kasparov has occasionally coached top players, including a brief period training Norwegian world champion Magnus Carlsen in 2009. He has also played numerous exhibition matches and simultaneous displays, promoting chess globally. In 2017, he participated in a blitz tournament in St. Louis, finishing with respectable results.
6.3 Public speaking and advisory roles
Kasparov is a sought‑after speaker on strategy, risk management, and the future of artificial intelligence. He has consulted for corporations, lectured at universities, and served as an advisor for chess‑related technology projects. He also remains active in chess commentary for major events.
7 Recognition and legacy
7.1 World records and accolades
Kasparov holds several records: the longest reign as world number one (255 months from 1985 to 2006, with a brief interruption), the most consecutive tournament wins (15 from 1981 to 1986), and the highest Elo rating (2851 at its peak, a record at the time). He received the Chess Oscar eleven times (1982, 1983, 1985–1988, 1990, 1991, 1994, 1995, 1999). In 2017, he was inducted into the World Chess Hall of Fame.
7.2 Influence on modern chess practice
Kasparov’s aggressive style and meticulous opening preparation set a new standard for professional chess. His use of computer databases and his contributions to opening theory remain influential. He inspired a generation of players to adopt dynamic, unbalanced play, particularly in the Sicilian and King’s Indian. His matches against Karpov are considered among the greatest in history, and his rivalry with Deep Blue advanced public understanding of artificial intelligence.
7.3 Cultural references and media portrayals
Kasparov has appeared in films, documentaries, and literature. He is the subject of the documentary *Kasparov* (2018) and was portrayed in the 2014 film *The Coldest Winter* (an abstract portrayal). His games have been analyzed in books and lectures worldwide. The 1997 Deep Blue match is often cited in discussions of human–machine competition and remains a pop‑culture touchstone. Kasparov’s name is synonymous with chess excellence and the intersection of human intellect and technology.
