Garry Kasparov and Anatoly Karpov played five World Championship matches between 1984 and 1990, contesting 144 games for the title, more than any other pair in chess history. Their rivalry defined elite chess for a decade and produced some of the deepest strategic battles the game has seen.
The two men were opposites in style and temperament. Karpov was the quiet positional python who squeezed opponents slowly, while Kasparov was the explosive attacker who thrived in sharp, calculated chaos. That clash of approaches made every match a study in contrasts.
The Marathon That Was Never Finished
Their first meeting, in 1984, remains one of the strangest events in chess history. The match used a "first to six wins" rule with no cap on games. Karpov, the defending champion, raced to a 4–0 lead and looked set to crush the young challenger.
Then the match slowed to a crawl. Karpov could not land the decisive fifth and sixth wins, while Kasparov clawed back. After five months and 48 games, the score stood at 5–3 for Karpov, with Kasparov having won two of the last three games and clearly gaining momentum.
FIDE President Florencio Campomanes stopped the match with no result, citing the health of the players. The decision outraged Kasparov, who felt he was being denied a comeback. The aborted 1984 match convinced FIDE to abandon open-ended formats and return to fixed-length title matches.
Kasparov Takes the Crown
A rematch was scheduled for 1985 under new rules: 24 games, with the champion retaining the title on a 12–12 tie. Kasparov won 13–11, becoming, at 22, the youngest undisputed World Champion at the time.
The rivalry was far from over. FIDE granted Karpov a rematch clause, and the two met again in 1986. Kasparov led comfortably before Karpov staged a fierce comeback, winning three games in a row, but Kasparov steadied and held on to retain his title.
| Year | Winner | Score | Format |
|---|---|---|---|
| 1984–85 | No result | 5–3 (Karpov) | First to 6 wins, aborted |
| 1985 | Kasparov | 13–11 | 24 games |
| 1986 | Kasparov | 12.5–11.5 | 24 games |
| 1987 | Drawn, Kasparov retained | 12–12 | 24 games |
| 1990 | Kasparov | 12.5–11.5 | 24 games |
Seville 1987 and the Final Game
The 1987 match in Seville produced one of the most dramatic finishes ever. Karpov led by one point going into the final game, meaning Kasparov had to win with the white pieces to keep his title, since a tie favored the champion.
Kasparov won that last game in a tense endgame, leveling the match at 12–12 and retaining the crown by the narrowest possible margin. A single must-win game deciding a world title is rare, and Kasparov’s Game 24 in Seville is remembered as one of the great pressure performances.
Karpov never lacked chances; across five matches the aggregate score stayed remarkably close, which is exactly why the rivalry mattered so much to both men and to the chess world watching.
Their last title match, in 1990, split between New York and Lyon, again went to Kasparov by a single point. It closed the championship chapter of their rivalry, though they continued to meet in tournaments for years.
Why the Rivalry Was So Even
The overall record across their world title games is startlingly balanced. Over 144 championship games, the two men were separated by only a handful of decisive results. This closeness came from how well their strengths canceled each other out.
Kasparov’s attacking preparation forced Karpov into complications, while Karpov’s defensive precision often neutralized the assault. Neither could rely on a single plan working twice, so both were pushed to constant innovation. The rivalry became a laboratory for opening theory, and lines from their matches are still studied today.
Several factors made their duel unique in chess history:
- Volume: No other pair has played anywhere near 144 world title games.
- Style contrast: Positional mastery against dynamic attack.
- Political backdrop: Their matches spanned the final years of the Soviet Union, with Kasparov often clashing with the chess establishment that had long favored Karpov.
- Consistency of quality: The games held elite standards across a decade.
Their Impact on Opening Theory
The sheer number of high-stakes games the two played turned their rivalry into a laboratory for opening research. Lines they tested under championship pressure became standard theory studied by players at every level for years afterward.
Both men, backed by teams of analysts, pushed preparation deeper than anyone before them. Karpov refined solid systems that gave nothing away, while Kasparov developed sharp, aggressive setups designed to create imbalance. Their contest advanced the whole understanding of several major openings.
Much of the opening theory taught today was stress-tested in the Kasparov-Karpov matches, giving their rivalry a technical legacy that reaches far beyond the results. Their games remain reference points in databases worldwide.
Beyond the Board
The rivalry carried political weight inside the USSR. Karpov was seen as the establishment champion, comfortable with the Soviet system, while Kasparov increasingly positioned himself as a reformer and outsider. Their contests took on symbolic meaning during a period of enormous change in the country.
After the championship years, both remained major figures. Kasparov dominated world chess until his retirement from professional play in 2005, holding the number one ranking for most of two decades. Karpov continued competing at a high level and later moved into politics.
Their rivalry set the standard by which all later chess duels are measured, and no pairing since has matched its length, balance, or intensity.
Modern fans sometimes debate whether any current rivalry could rival it. The honest answer is that the conditions that produced it, two supreme talents of opposite styles, forced together repeatedly by the format of the era, are unlikely to be repeated. Kasparov and Karpov gave chess its defining feud, and the games remain essential study for anyone serious about the sport.
