FIDE World Chess Championship 1984 – 1985 was held in Moscow, Soviet Union, between reigning champion Anatoly Karpov and challenger Garry Kasparov, both representing the Soviet Union. The match took place in the Hall of Columns in the House of Unions. Karpov led 5–0 after 27 games, but Kasparov staged a dramatic comeback to 5–3 before FIDE President Florencio Campomanes controversially terminated the match after 48 games. Karpov remained champion, but the chess world would never be the same. This remains the longest world championship match in history.

Reigning Champion: Anatoly Karpov
Born: May 23, 1951, Zlatoust, Russian SFSR, Soviet Union (now Russia)
Anatoly Karpov entered the match as world champion since 1975. Renowned for his deep positional understanding and surgical precision, he had successfully defended his title twice against Viktor Korchnoi. In the early stages of the 1984 match, Karpov dominated with clinical positional play, building a commanding 5–0 lead. However, the match’s extreme duration began to affect his physical condition, and he was unable to score the decisive sixth win. As Kasparov gained momentum, the match was controversially halted. Despite retaining the title, the decision cast a shadow over his legacy. Karpov’s resilience and classical style continued to inspire future generations.

Challenger: Garry Kasparov
Born: April 13, 1963, Baku, Soviet Union (now Azerbaijan)
At just 21 years old, Garry Kasparov became the youngest world championship challenger in history. Known for his dynamic style and rigorous home preparation, he qualified by defeating Alexander Beliavsky, Viktor Korchnoi, and Vasily Smyslov in the 1983 Candidates cycle. Initially overwhelmed and falling behind 0–5, Kasparov changed strategy—playing solidly and testing Karpov’s endurance. His first victory in Game 32 broke the spell, and by Game 47, he had narrowed the gap to 5–3. Though denied a full comeback by the match’s abrupt end, Kasparov’s fighting spirit won him admiration worldwide. This was the beginning of a legendary rivalry.

Historical and Cultural Context
This world championship took place during a tense Cold War period, when the Soviet Union championed chess as a symbol of intellectual supremacy. The 1984 match, played entirely in Moscow, unfolded amid high political tension and intense global attention. The unprecedented length of the match—nearly five months—raised questions about fairness, stamina, and FIDE’s governance. Campomanes’ controversial decision to end the match without a result sparked outrage and debate. To many, this was more than a sporting contest; it was a clash of generations, ideologies, and playing styles.
