Garry Kasparov

Garry Kimovich Kasparov (Russian: Гарри Кимович Каспаров; born Garik Kimovich Weinstein; 13 April 1963) is a Russian chess grandmaster, author, and political activist. Widely considered one of the strongest players in history, he became the youngest undisputed World Chess Champion in 1985 at age 22 by defeating Anatoly Karpov after a series of matches, and retained the title until 2000. His 15-year reign as champion remains the longest in the modern era, during which he pioneered aggressive tactics, exhaustive opening theory, and unmatched competitive longevity.

Kasparov achieved a peak Elo rating of 2851 in 1999—the highest at the time—and was the first to surpass 2800, while occupying the world number one position for a record 255 months. In 1997, he lost a rematch to IBM's Deep Blue supercomputer by a score of 2½–3½, a defeat that underscored rapid progress in computational chess power despite his earlier victory over the machine in 1996. The match sparked debates over human preparation versus machine brute force, with Kasparov alleging irregularities in Deep Blue's handling.

Garry Kasparov was born Garik Kimovich Weinstein on April 13, 1963, in Baku, Azerbaijan SSR, Soviet Union, to father Kim Moiseyevich Weinstein, an Ashkenazi Jew possibly of German descent, and mother Klara Shagenovna Gasparian, an Armenian whose parents hailed from Nagorno-Karabakh. His parents, like many in Baku's ethnic mosaic, spoke Russian at home, reflecting the city's Soviet-era cosmopolitanism where inter-ethnic marriages were common despite underlying tensions.

In 1975, at age twelve, Kasparov adopted his mother's Russified surname Kasparova (becoming Garry Kimovich Kasparov) with local authorities' approval, a move attributed to shielding him from antisemitic barriers prevalent in Soviet institutions. This upbringing in Baku's multi-ethnic yet hierarchically rigid environment—marked by Russian as the lingua franca and Armenian-Jewish paternal lineages—instilled resilience, as his mother emphasized self-reliance and ambition in a context where ethnic minorities navigated systemic favoritism toward Russians.
