Fifteen centuries of a wargame in miniature, from chaturanga in the courts of Gupta India through Steinitz, Fischer, and Kasparov to the engines that now play it better than any human ever will.
Two players, sixty-four squares, thirty-two pieces, perfect information, no chance. The deepest combinatorial structure ever absorbed into a popular pastime.
Chess is the rare game whose strongest play has been continuously documented for five hundred years. The notation invented by Philidor in the eighteenth century lets a contemporary reader replay a specific game from 1620. The opening repertoires of Lasker and Capablanca are still cited in current grandmaster preparation. The historical continuity is part of what makes the game culturally heavy in a way that no other contest is.
This deck moves through that continuity: from the Gupta-era origin of chaturanga through medieval Europe's slow modernisation of the rules, the long Soviet century, the 1972 match in Reykjavík that broke the Soviet hegemony, the engines that broke the humans, and the post-engine renaissance led by a Norwegian, an Indian, and a teenager from Chennai.
The earliest game recognisable as a chess ancestor is chaturanga, played in Gupta-period north India around the sixth century. The name means "four divisions" — infantry, cavalry, elephants, chariots — a description of an Indian battlefield. Two early Sanskrit references in the seventh-century Harshacharita of Bana and the Persian-Pahlavi Karnamak-i Artakhshir are the strongest documentary anchors.
The pieces of chaturanga map onto modern chess with rough fidelity. The raja is the king. The mantri (minister) is the ancestor of the queen, but moved only one square diagonally. The gaja (elephant) is the ancestor of the bishop, with a similarly limited move. The ashva (horse) is already the knight, with the L-shaped jump preserved unbroken to the present day. The ratha (chariot) is the rook, the most powerful piece on the board for most of the game's first millennium.
The dice-played four-handed variant chaturaji, attested later, may have preceded the two-player form, or descended from it. The textual record is too sparse to settle the question.
By the late sixth century the game had crossed into Sasanian Persia under the name shatranj, with the king now shah. The word checkmate descends from Persian shah mat — "the king is helpless" — and Spanish jaque, French échecs, and English chess all derive from the same root.
The Arab conquests of the seventh and eighth centuries carried shatranj across the Caliphate. From the ninth to the eleventh century the strongest known players were Arab and Persian masters working in Baghdad — al-Adli ar-Rumi, as-Suli, al-Lajlaj. As-Suli's tenth-century treatise on shatranj endgames was authoritative for two centuries; an Arabic proverb still in use praises a sharp player as "playing like as-Suli."
The Caliphate produced the first written analysis of openings, the first composed problems (mansubat), and the first concept of player ratings: a five-class system from aliyat (the masters) downward. The infrastructure of competitive chess is Islamic before it is European.
Chess entered Europe through Spain and Sicily in the tenth and eleventh centuries — Moorish Spain in particular — and through Byzantine and Russian channels in the east. By the thirteenth century it was a courtly pastime across Latin Christendom. The thirteenth-century Libro de los juegos, commissioned by Alfonso X of Castile in 1283, is the most important early European chess document: a richly illuminated manuscript with hundreds of problems and the rules then current.
For five centuries the European game preserved the slow Persian moves of the queen and bishop. Games crawled. Strategy was elementary; positional play in the modern sense did not exist. The piece names slowly Europeanised — the elephant became the bishop in England, the standard-bearer or fool (fou) in France, the runner (Läufer) in Germany.
The decisive change came not from theory but from the rules.
Sometime in the late fifteenth century, in Valencia or thereabouts, the rules of the queen and the bishop were changed. The queen, formerly the weakest piece on the board, became the strongest, with sweeping rook-and-bishop reach. The bishop became a long-diagonal piece. The pawn was given the option of a two-square first move; en passant capture, castling, and the underlying tempo of opening play all followed.
The 1495 Catalan poem Scachs d'amor is the earliest known game played under the new rules. Modern historians (Govert Westerveld and others) have argued that the redesign of the queen mirrored the rise of Isabella I of Castile, the first European queen regnant whose military and political power matched a king's. Whether or not the etymology is right, the rule change made chess into a fast, sharp, attacking game for the first time. The pace of theory accelerated immediately.
The earliest printed chess book — Luis Ramirez de Lucena's Repetición de amores y arte de ajedrez (Salamanca, 1497) — already analyses ten openings recognisable today. Pedro Damiano's 1512 manual ran to eight editions. By 1550 the new chess was European-standard.
François-André Danican Philidor (1726–1795) was a French composer of light operas — his Tom Jones (1765) was performed for decades — and the strongest chess player of the eighteenth century. He was the dominant figure at the Café de la Régence in Paris, the western world's chess capital, where he gave blindfold simultaneous exhibitions that astonished onlookers.
Philidor's L'Analyse du jeu des Échecs (London, 1749) is the first modern chess book. Its central claim — "the pawns are the soul of chess" — articulated for the first time the idea that the pawn structure governs the whole strategic game. Pawn chains, mobile pawn majorities, weak squares: the Philidorian vocabulary remains in current use.
The verdict took a century to be accepted. The brilliant attacking play of the early nineteenth century — La Bourdonnais against McDonnell in their 1834 match in London, the first event the chess press treated as a championship — owed more to gambit theory than to Philidor's positional principles. Philidor's revenge would come through Steinitz.
Howard Staunton (1810–1874) was an English Shakespearean editor and the strongest player of the 1840s. His 1843 match victory over Pierre Saint-Amant in Paris was treated as a de facto championship. He organised the 1851 London tournament, the first international chess tournament — won by Adolf Anderssen — which set the format for every championship event since.
His most durable contribution was a piece design. The Staunton pattern, designed by Nathaniel Cooke and registered in 1849, gave the pieces silhouettes that were unambiguous, stackable for storage, and pleasing to the hand. The knight's head was modelled on the horse of the Parthenon's Selene. The pattern was endorsed by Staunton, marketed as the Staunton pieces, and became the international standard. Every tournament-grade chess set in the world today is descended from it.
Anderssen's Immortal Game against Kieseritzky (London, 1851) and the Evergreen Game against Dufresne (Berlin, 1852) gave the popular imagination the romantic-sacrificial style of mid-century play.
Wilhelm Steinitz (1836–1900), born in Prague, won the inaugural undisputed world championship match against Johannes Zukertort in 1886, played in New York, St. Louis, and New Orleans. The score, +10 −5 =5, established Steinitz as the first formally recognised world chess champion. He held the title for eight years.
Steinitz's deeper contribution was theoretical. The modern school he founded held that attack must be earned by accumulated positional advantages — the bishop pair, control of an open file, a weak pawn, a superior pawn structure — rather than launched in the romantic style of Anderssen. The shift from gambit-and-sacrifice to slow positional play is the most important strategic revolution in the game's history. Steinitz wrote it up in The Modern Chess Instructor (1889).
His final years were difficult. The 1894 match loss to Lasker, declining mental health, and poverty marked his last decade. He died in a New York asylum.
Emanuel Lasker (1868–1941), German mathematician and philosopher, held the world championship for twenty-seven years — the longest reign in the title's history. He took it from Steinitz in 1894 and lost it to Capablanca in 1921. The interval included the First World War, during which the championship lay dormant.
Lasker's mathematical work — particularly the Lasker–Noether theorem in commutative algebra (1905) — was substantial enough to give him a parallel reputation among mathematicians. He published a 1907 book on the philosophy of struggle, Kampf, which Albert Einstein read and discussed with him.
His chess style was psychological in a way Steinitz's was not. Lasker would deliberately enter inferior positions if he believed his opponent would handle them badly — a practical, gladiatorial approach distinct from objective best-play orthodoxy. The 1921 loss to Capablanca came when his opponent's positional clarity gave nothing for the psychology to attack.
José Raúl Capablanca (1888–1942), Cuban diplomat and the most naturally gifted player of his era, took the title from Lasker in Havana in 1921 with a +4 =10 score. Capablanca was famous for an effortless positional style — what contemporaries called the Capablanca technique — that made the game look simple even as he won decisive endgames from positions that appeared drawn.
His 1916–1924 unbeaten streak ran to eight years. The endgame manuals of the next century would be built on his games. Chess Fundamentals (1921) remains the most-recommended introductory chess book a hundred years later.
He lost the title to Alekhine in 1927 in Buenos Aires, in a brutal match — thirty-four games, six wins for Alekhine to three for Capablanca, twenty-five draws. Alekhine then refused him a return match for the rest of his life, a denial that has been argued ever since. Capablanca died of a stroke at the Manhattan Chess Club in 1942, watching others play.
Alexander Alekhine (1892–1946), Russian-born and later French-naturalised, held the title from 1927 to his death in 1946 (with a brief 1935–1937 interruption when he lost it to Max Euwe and won it back). His attacking style was more dynamic than Capablanca's; his games are still studied for combinational depth.
The wartime years were ugly. Alekhine wrote articles for Nazi-controlled chess publications in 1941 framed in racist anti-Jewish terms; how much of that text was his own, how much was inserted, and how much he disclaimed afterwards remains contested. He died in Estoril, Portugal, in March 1946 — alone in a hotel room — under circumstances some authors have argued were a suicide or even an assassination, but the official cause was choking.
The 1948 tournament held to determine his successor, played in The Hague and Moscow, established the FIDE control of the title that lasted until 1993.
Mikhail Botvinnik (1911–1995), an electrical engineer from Leningrad, won the 1948 title tournament and held the championship — with two short interruptions — until 1963. More importantly, he founded the Soviet chess school: a state-funded system of trainers, schools, and analytical methodology that would produce nearly every world champion from 1948 to 2000.
The Soviet method emphasised home preparation, deep opening analysis, the systematic study of typical middlegame structures, and rigorous physical training. Botvinnik personally coached three future world champions — Karpov, Kasparov, and Kramnik — at his school in Moscow.
The succession through the post-war decades — Vasily Smyslov (1957), Mikhail Tal (1960, the Latvian "magician of Riga," whose attacking style remains iconic), Tigran Petrosian (1963, the Armenian master of prophylactic defence), Boris Spassky (1969) — was an entirely Soviet affair. The state's investment in chess as soft-power propaganda was enormous. The chess board was a Cold War theatre.
The 1972 World Championship in Reykjavík between Boris Spassky of the USSR and Bobby Fischer of the United States was the most heavily politicised single sporting event of the Cold War. Fischer's path to the title had been a wave of demolitions: 6–0 against Taimanov, 6–0 against Larsen, 6.5–2.5 against Petrosian — three consecutive Candidates matches without precedent in the title's history.
The match itself was theatrical. Fischer lost game one, defaulted game two over a dispute about the cameras, then won seven of the next nineteen. The final score: 12.5–8.5. Fischer became the first American world champion. The match was front-page news worldwide for two months. The chess boom that followed — books, sets, clubs, magazines — was the largest in the game's history.
Fischer's Game 6, in which he opened with the English (unusual for him) and won a model positional game, drew Spassky to applaud his opponent at the board. The recording of that applause is one of the great moments in chess history.
Fischer never defended the title. His 1975 negotiation with FIDE over the format — he insisted on first-to-ten-wins, draws not counting, with a 9–9 retention rule for the champion — broke down. FIDE awarded the title to Anatoly Karpov by forfeit. Fischer disappeared from professional chess for twenty years.
The 1992 unsanctioned rematch with Spassky in Yugoslavia, played in violation of UN sanctions, drew an arrest warrant from the United States. Fischer, born in Chicago in 1943, never returned home. He gave bizarre, increasingly anti-Semitic interviews from various international refuges. Iceland — remembering 1972 — granted him citizenship in 2005 after a Japanese detention. He died in Reykjavík in 2008.
His chess legacy is unblemished. My 60 Memorable Games (1969) is among the finest collections ever published by a player. The 1972 match games are taught in every serious chess school. The post-1972 reclusiveness and the late paranoia are a separate, sadder story.
Anatoly Karpov (b. 1951) inherited the title from Fischer in 1975 and held it for a decade. His style was the antithesis of Fischer's: positional, prophylactic, slow, suffocating. Opponents complained that Karpov did not seem to be doing anything in particular and then — twenty moves later — they had no good moves left.
His tournament record through the late 1970s and early 1980s is the strongest of any player who is not Garry Kasparov. He won 160 first-place finishes in his career — more than any player in history. The 1978 and 1981 matches against the defector Viktor Korchnoi (Baguio City and Merano) were politically charged Soviet vs. émigré confrontations that Karpov won.
The challenge that defined the rest of his career came from his own country in 1984.
Garry Kasparov (b. 1963 in Baku, Azerbaijani SSR) was the youngest world champion in history when he took the title from Karpov in 1985 at twenty-two. His style was aggressive, dynamic, deeply prepared. The opening preparation Kasparov brought to top-level chess — analysis sessions running deep into novelty-rich variations — set a new standard that has only been raised by the engines.
He held the FIDE title from 1985 to 1993, then formed the breakaway Professional Chess Association after a dispute with FIDE over commercial rights, holding the PCA-recognised title until 2000 when he lost it to Vladimir Kramnik. He retired from professional chess in 2005 to focus on Russian opposition politics — work that has continued in exile.
His 2851 peak rating (July 1999) stood for fourteen years, until Magnus Carlsen surpassed it in 2013. The five-volume My Great Predecessors (2003–2006) is the most significant work of chess history written by a player.
From 1984 to 1990, Karpov and Kasparov played five world championship matches — 144 games, the most extensive championship rivalry in the game's history. The first, Moscow 1984, was halted by the FIDE president Florencio Campomanes after five months and forty-eight games with the score Karpov +5 −3 = the rest, on grounds of player exhaustion. The decision is contested to this day.
The 1985 rematch — Kasparov won 13–11. The 1986 match in London and Leningrad — Kasparov retained 12.5–11.5. The 1987 Seville match ended 12–12, with Kasparov keeping the title under the champion-retains rule. The 1990 New York/Lyon match — Kasparov 12.5–11.5.
The matches produced some of the deepest chess ever played, and a body of analysed games that anchors several modern opening systems — particularly the Najdorf Sicilian, the King's Indian, and the Grünfeld. The political subtext (Karpov was the establishment Soviet; Kasparov a half-Armenian, half-Jewish reformer) was inescapable.
In May 1997 in New York, IBM's Deep Blue defeated Kasparov 3.5–2.5 in a six-game match. It was the first time a reigning world champion had lost a match to a computer at standard time controls. The game-six victory came in nineteen moves; Kasparov resigned with the look of a man who had seen something disturbing.
The Deep Blue team — Feng-hsiung Hsu, Murray Campbell, Joe Hoane, with grandmaster consultants — had built a custom chip-based parallel system evaluating roughly 200 million positions per second. The hardware/software combination represented a decade of incremental improvement over its predecessor Deep Thought (1989).
Kasparov's accusations of human intervention — fuelled by IBM's refusal to release Deep Blue's logs and the immediate dismantling of the machine after the match — coloured his account for years. The contemporary consensus is that Deep Blue won fairly. The wider verdict is that Kasparov was simply the last world champion who could compete against silicon. Within a decade no human was a serious match for any consumer chess engine.
The classical title passed to Vladimir Kramnik in 2000, when he beat Kasparov 8.5–6.5 in London using the Berlin Defence to neutralise Kasparov's white preparation. Kramnik's style was severe and technically clean. He held the title until 2007.
The schism between FIDE's title and the classical lineage was finally resolved in the 2006 Kramnik–Topalov reunification match in Elista — a bitter contest disrupted by accusations of cheating in the players' bathrooms (the "Toiletgate" affair) — which Kramnik won.
Viswanathan Anand (b. 1969 in Madras), the first Indian world champion, won the unified title in 2007 and held it through three successful defences (against Kramnik 2008, Topalov 2010, Boris Gelfand 2012) before losing to Carlsen in 2013. Anand's career record — five world championship titles in three formats — and his role as the figure who inspired the Indian chess explosion of the 2010s and 2020s puts him among the most consequential players of the modern era.
Magnus Carlsen (b. 1990 in Tønsberg, Norway), grandmaster at thirteen, took the title from Anand in Chennai in November 2013 with three games to spare. He held it for ten years and then voluntarily relinquished it in 2023, citing lack of motivation to defend.
Carlsen's strength is not based on opening preparation in the Kasparov mode. He plays a wide range of openings, often modest by elite standards, and grinds advantages out of objectively level positions in the endgame — a style closer to Karpov than to Kasparov, but more relentless than either. His 2882 peak rating (May 2014) is the highest in chess history.
His four successful title defences — Anand 2014, Sergey Karjakin 2016, Fabiano Caruana 2018, Ian Nepomniachtchi 2021 — were progressively more dominant. The 2021 match against Nepomniachtchi was won outright with three games unplayed. By the time of Carlsen's 2023 abdication, the consensus that he was the strongest player who had ever lived was nearly universal among grandmasters.
Carlsen's 2023 abdication produced a Nepomniachtchi–Ding Liren match in Astana. Ding, the first Chinese world champion, won 9.5–8.5 in a tense contest decided in tiebreaks. His subsequent reign was haunted by mental-health issues that affected his play.
In December 2024 in Singapore, Gukesh Dommaraju (b. 2006 in Chennai) defeated Ding 7.5–6.5 to become the youngest undisputed world chess champion in history at eighteen. Gukesh had won the 2024 Candidates Tournament at seventeen, the youngest ever. The match was decided in game fourteen, Ding having blundered a winning endgame.
The Indian dominance is striking. Anand was the first; Gukesh, Praggnanandhaa, Vidit Gujrathi, Arjun Erigaisi, and Nihal Sarin form the strongest national cohort in the world after the United States. The 2024 Chess Olympiad in Budapest, won by India in both open and women's sections, is the closing punctuation on the Soviet century.
The strongest current chess engine is Stockfish, an open-source project descended from Tord Romstad's 2008 Glaurung. By 2024 Stockfish 16 played at an estimated 3640 Elo — about 750 rating points above the strongest human, an unbridgeable gap. The 2020 integration of NNUE (Efficiently Updatable Neural Network) — borrowed from Japanese shogi engines — gave Stockfish a hybrid alpha-beta-plus-neural evaluation that no traditional engine has matched.
Komodo Dragon, the leading commercial engine until its absorption into Chess.com, was the principal Stockfish competitor through the 2010s. Leela Chess Zero (LCZero), a community-built reimplementation of DeepMind's AlphaZero approach, has been the strongest pure-neural engine since 2018.
The functional consequence is that opening preparation at the highest levels is now an engine-mediated activity. A grandmaster's home preparation involves hundreds of hours of engine analysis on cloud-cluster hardware. The 1990s notion of human originality at the board has been replaced by a more honest accounting: the originality is in choosing which engine line to play, and remembering it under pressure.
In December 2017, DeepMind published a paper announcing that AlphaZero, a neural-network engine trained from self-play with no human chess knowledge beyond the rules, had defeated the then-strongest version of Stockfish 28 wins, 0 losses, 72 draws in a hundred-game match.
The result was qualified — the Stockfish version used was hampered by hardware and time-control choices — but the games themselves were a revelation. AlphaZero played positionally fluid, sacrifice-rich, long-term-pressure chess that resembled human masters more than the materialistic engines that had preceded it. The games selected for the paper, particularly its handling of the King's Indian Defence and queen sacrifices for long-term king-attack, became immediately influential.
The methodology — Monte Carlo Tree Search guided by a deep neural net trained by self-play — was the foundation of modern AI game-playing systems. The Leela Chess Zero project replicated the approach in open form, and Stockfish's 2020 NNUE integration responded to it. The "AlphaZero style" has become a known category in opening analysis.
Modern opening theory occupies more printed and digital pages than the rest of chess writing combined. The standard reference work — the Encyclopaedia of Chess Openings (ECO), published by Šahovski Informator from 1974 — codifies positions by ECO code (A00 through E99) and is used by every serious player. Specific lines (the Najdorf Sicilian B96–B99, the Grünfeld D70–D99, the Berlin Defence C65–C67) carry decades of accumulated analysis.
The endgame has been more decisively solved. Endgame tablebases — exhaustive computer-generated databases of all positions with a small number of pieces — give perfect play for any position with up to seven pieces on the board (Lomonosov tablebases, 2012). The Syzygy 7-piece tablebases occupy several terabytes; specialised hardware is required to query them at speed.
The tablebase results have produced surprises. A queen-and-knight versus rook-and-bishop ending, long thought drawn, can be a 545-move forced win. The longest known forced mate in seven-piece tablebases runs 549 moves, far beyond the FIDE 50-move rule. The results have not changed practical chess much; they have changed our understanding of what chess actually is.
The Internet Chess Club (ICC), founded 1995, ran the first major online chess platform. The contemporary landscape is dominated by two sites. Chess.com, founded 2007 by Erik Allebest and Jay Severson, is the larger commercial platform — by 2024 it had over 150 million registered accounts and ran the dominant streaming and tournament infrastructure. Lichess, founded 2010 by Thibault Duplessis as a non-profit open-source project, is funded by donations and runs the second-largest player base, with a reputation for technical quality and ad-free experience.
The platforms transformed the competitive game. Online rapid and blitz ratings (often higher than classical FIDE ratings, given more games and faster turnover) became a parallel competitive currency. Streaming on Twitch and YouTube turned grandmasters into entertainment figures — Hikaru Nakamura, Levy Rozman (GothamChess), the Botez sisters, Anna Cramling, Daniel Naroditsky.
The platforms also became the principal pipeline for new players. By 2024, far more chess was played online than over the board.
The COVID-19 lockdowns of 2020 produced the largest growth in chess participation since 1972. Three causes converged. The first was simple time: a hundred million people stuck at home, looking for cognitive entertainment. The second was Netflix's The Queen's Gambit (October 2020), a seven-episode adaptation of Walter Tevis's 1983 novel that became a global cultural event; chess-set sales spiked 250% in the weeks after release. The third was the streamer ecosystem on Twitch and YouTube, primed to absorb the new audience.
Chess.com's daily new account creation went from approximately 5,000 in early 2020 to over 100,000 in late 2020, and stayed elevated through 2024. The Magnus Carlsen vs. Hans Niemann cheating scandal of 2022 — never definitively resolved, settled out of court in 2023 — kept chess in the mainstream news cycle in a way no chess controversy had been since the 1990s.
By 2024 the user base of online chess platforms was roughly an order of magnitude larger than it had been in 2019. The post-pandemic chess world is permanently larger than the pre-pandemic one.

Fischer's My 60 Memorable Games (the standard collection by any player), Kasparov's My Great Predecessors (the most thorough modern history of the title), and David Edmonds and John Eidinow's Bobby Fischer Goes to War (the best account of Reykjavík 1972). For technique, start Silman; for the experience of playing, Bronstein on Zurich 1953 is unmatched.
The standard defence — chess teaches concentration, planning, pattern recognition, the discipline of consequence — is true and inadequate. Many other activities teach those things. What chess does that little else does is preserve a five-hundred-year continuous record of human strategic thought, in a form that is replayable, study-able, and unambiguous. The notation 1.e4 e5 2.Nf3 Nc6 means the same in 2026 as it did in 1850.
The engine era has not killed this. The strongest engines play moves that human masters can study and partially imitate. The aesthetic categories — sound positional play, brilliant combination, deep endgame technique — have survived their absorption into machine play. Carlsen still wins; Gukesh still wins; the games are still beautiful.
What has changed is the pretence that chess is a contest of pure human originality. It is not. It never was. Lasker prepared lines; Kasparov prepared lines; Carlsen prepares lines. The engines have only made the preparation more honest. The play remains, in the moment of execution, irreducibly human.
The contemporary picture: Gukesh Dommaraju holds the classical title at nineteen. Carlsen, retired from the championship cycle but still the world's highest-rated active player, dominates rapid and blitz. The Indian junior pipeline shows no sign of slowing. The Chinese, American, and Uzbek programmes are competitive but trail.
The institutions are fragile. FIDE under Arkady Dvorkovich faces continuing legitimacy questions over its Russian links and its handling of the Niemann cheating affair. The Saudi-funded Esports World Cup has begun integrating chess events with prize pools larger than any FIDE tournament. The competitive landscape five years from now is genuinely uncertain in a way it has not been since the 1993 Kasparov–FIDE schism.
The popular game has never been healthier. Chess.com's user base continues to grow. Streaming chess remains a robust entertainment category. The number of strong human players is at an all-time high. The game itself, an artifact older than printed books, retains an unaccountable hold.
