The Moment
December 12, 2024. Singapore. An eighteen-year-old from Chennai named Gukesh Dommaraju sits across from Ding Liren, the reigning World Chess Champion. The score is tied 6.5-6.5. This is the final game. Gukesh is losing. His position is worse. The clock is ticking. And then Ding Liren, under unbearable pressure, makes a mistake, one move, one moment of miscalculation, and Gukesh sees it. Within minutes, the game is over. Gukesh Dommaraju becomes the youngest World Chess Champion in history.
He buries his face in his hands and weeps. His mother, watching from the audience, weeps too. The Indian contingent erupts. A teenager from Tamil Nadu now holds the title that Bobby Fischer, Garry Kasparov, and Viswanathan Anand once held.
But here is what makes this moment different from every other sporting victory: the game Gukesh just won was invented in India. Not metaphorically. Not loosely. Chess, the sixty-four squares, the strategic warfare, the infinite complexity contained in a finite board, was created on Indian soil roughly 1,500 years ago, in the courts of the Gupta Empire, at a time when India was the intellectual centre of the known world.
The thread that connects a sixth-century courtier in Pataliputra to an eighteen-year-old in Singapore in 2024 is unbroken. It passes through Persian emperors, Arab scholars, medieval European queens, Soviet grandmasters, IBM supercomputers, and Google’s AlphaZero. It is, arguably, the longest continuous intellectual tradition in human history, and it began with a game called Chaturanga.
The Origin: Chaturanga
The Gupta Empire (c. 320–550 CE) was India’s golden age of intellectual achievement. During this period, Indian mathematicians invented the concept of zero and the decimal number system, Aryabhata calculated the Earth’s circumference to within 1% accuracy, Kalidasa wrote Sanskrit literature that rivalled Homer, and the Nalanda university complex attracted scholars from China, Korea, Japan, and Central Asia.
It was in this environment, a civilisation obsessed with mathematics, logic, and strategic thinking, that chess was born.
The game was called Chaturanga (चतुरङ्ग), a Sanskrit word meaning “four divisions”, referring to the four branches of the Indian military: infantry, cavalry, elephants, and chariots. These became, respectively, the pawns, knights, bishops, and rooks of modern chess. The game was played on an 8×8 grid called the ashtāpada (“eight-footed”), a board that had existed in India for centuries as a surface for dice games and racing games.
What made Chaturanga revolutionary was the elimination of dice. Earlier Indian board games, like Pachisi and Chaupar, relied on chance. Chaturanga was pure strategy. Every piece was visible. Every move was deliberate. The outcome depended entirely on the players’ ability to think ahead. In a civilisation that valued mental discipline, this was a profound innovation.
The earliest literary reference to Chaturanga appears in the Vasavadatta by Subandhu, a Sanskrit prose romance written around 600 CE. Subandhu describes the monsoon season as a time “when theichneumons are at rest from the game of chaturanga with the snakes,” using the game as a metaphor so casually that it suggests chess was already well-known in Indian courtly life.
The Harsha-charita by Banabhatta (c. 625 CE) provides another reference, describing a peaceful kingdom where “the only ashtapada played was on the board”, implying that in less peaceful times, the game’s military strategy had real-world applications.
Chaturanga’s pieces differed from modern chess in important ways. The most powerful piece was not a queen but a mantri (counselor or minister), who could move only one square diagonally, far weaker than the modern queen. The elephant (gaja) moved two squares diagonally, jumping over the intermediate square, nothing like the modern bishop’s unlimited diagonal range. The horse (ashva) moved in the L-shape that survives unchanged today. The chariot (ratha) moved in straight lines, like the modern rook. And the king (raja) moved one square in any direction, just as it does now.
The objective was the same as modern chess: capture the opponent’s king. The concept of “checkmate”, an inescapable attack on the king, was already present. Indian military philosophy, with its emphasis on the king as the centre of the army’s purpose, shaped the game’s fundamental logic: protect the king at all costs, deploy your forces strategically, sacrifice lesser pieces for greater advantage.
The connection between Chaturanga and the Arthashastra, Kautilya’s treatise on statecraft and military strategy, is debated by historians but suggestive. Both share the same worldview: that warfare is an exercise in calculated strategy, that deception is legitimate, that the outcome depends not on divine favour but on human intelligence. Chess was, in a sense, Kautilya’s philosophy turned into a game.
The Journey West
Chess did not stay in India. It couldn’t. A game this compelling was destined to travel.
The first and most significant transmission was to Persia. The Sasanian Empire had extensive diplomatic and trade contacts with the Gupta and post-Gupta kingdoms of India, and sometime in the sixth century, the exact date is disputed, Chaturanga crossed the border and became Chatrang, later Shatranj in Persian.
A Persian text called the Karnamak-i Artakhshatr-i Papakan (c. 600 CE) mentions Chatrang as a game that came from India. The Wizarishn-i Chatrang (“Explanation of Chess”), written in Middle Persian, explicitly describes the game as an Indian invention presented to the Sasanian king Khosrow I (531–579 CE) as a challenge: “Can your wisest men figure out how this game works?” The Persian court not only figured it out, they improved the rules and made it their own.
The Arab conquest of Persia in the seventh century spread Shatranj across the Islamic world with extraordinary speed. Arab scholars embraced the game with intellectual passion. Al-Adli, As-Suli, and Al-Lajlaj, master players of the ninth and tenth centuries, wrote the first systematic treatises on chess strategy. They developed mansubat, composed chess problems, the ancestors of modern chess puzzles. The game became a standard part of Arab courtly education, alongside poetry, calligraphy, and horsemanship.
From the Arab world, chess entered Europe through two main routes: the Moorish conquest of Spain (711 CE onwards) and trade routes through Constantinople and the Byzantine Empire. By the year 1000, chess was played across Europe, but it was still Shatranj, with the weak counselor and the limited elephant.
The transformation happened in late fifteenth-century Europe, probably in Spain or Italy. Around 1475, the rules changed dramatically. The counselor became the queen, and was given the power to move any number of squares in any direction, making it the most powerful piece on the board. The elephant became the bishop, with unlimited diagonal movement. Pawns gained the option of moving two squares on their first move. Castling was introduced. En passant was codified.
These changes made chess faster, more aggressive, and more dramatic. The “new chess”, scacchi alla rabiosa (“mad chess”) as Italians called it, spread across Europe within decades. The Spanish priest Ruy López de Segura wrote one of the first chess manuals in 1561. The opening he described, the Ruy López, is still played in world championship matches today.
A game born in sixth-century India had been adopted by Persia, transmitted by Arabs, transformed by Europeans, and was about to conquer the world. The board and the basic concept, two armies, sixty-four squares, capture the king, remained Indian. Everything else had evolved.
The Mathematics
Chess has always been inseparable from mathematics. The most famous mathematical story connected to chess is the wheat and chessboard problem, which appears in various forms across Indian and Persian literature.
The legend goes that the inventor of chess presented it to a king, who was so delighted that he offered any reward. The inventor asked for a modest-sounding payment: one grain of wheat on the first square of the chessboard, two on the second, four on the third, doubling each time until all sixty-four squares were filled. The king laughed at the simplicity of the request, until his mathematicians calculated the total: 2⁶⁴ – 1 = 18,446,744,073,709,551,615 grains. More wheat than exists on the entire planet. The story illustrates exponential growth, and the deceptive power of doubling, with an elegance that mathematics textbooks still use today.
The complexity of chess itself is staggering. Claude Shannon, the father of information theory, calculated in his landmark 1950 paper that the number of possible chess games is approximately 10^120, a number known as the Shannon number. To put this in perspective, the estimated number of atoms in the observable universe is roughly 10^80. There are more possible chess games than atoms in the universe. This is what makes chess computationally “interesting”, it cannot be solved by brute force, even by the most powerful computers imaginable.
This mathematical richness made chess the default testbed for artificial intelligence research:
- 1950, Claude Shannon publishes “Programming a Computer for Playing Chess,” establishing the theoretical framework
- 1997, IBM’s Deep Blue defeats world champion Garry Kasparov, the first time a computer beats a reigning champion under standard tournament conditions
- 2017, Google’s AlphaZero teaches itself chess from scratch in four hours and then destroys Stockfish, the strongest conventional chess engine, winning 28 games, drawing 72, and losing none
AlphaZero’s achievement was particularly significant. It learned chess with zero human input, no opening databases, no endgame tables, no human games to study. It simply played against itself millions of times and discovered chess strategy from first principles. Some of its moves stunned grandmasters, sacrificing material in ways that looked reckless but turned out to be brilliantly calculated. AlphaZero was, in a sense, reinventing chess the way India’s original players must have discovered it: through pure pattern recognition and strategic intuition.
The connection between chess and modern artificial intelligence runs deep. Many of the algorithms used in today’s AI systems, tree search, evaluation functions, neural network training, were first developed for chess. The game that India invented 1,500 years ago helped create the technology that may define the next century.
India’s Chess Revolution
For centuries after inventing chess, India was a footnote in the game’s competitive history. While the Soviet Union dominated world chess from the 1940s through the 1990s, producing champions like Botvinnik, Tal, Petrosian, Spassky, Karpov, and Kasparov, India had no grandmasters, no national infrastructure, and no presence in international competition.
One man changed everything.
Viswanathan Anand became India’s first Grandmaster in 1988 at the age of eighteen. He went on to become World Chess Champion five times (2000, 2007, 2008, 2010, 2012), one of only a handful of players to hold the title across multiple formats. But Anand’s greatest contribution wasn’t his titles, it was what he proved: that an Indian could compete with and defeat the best in the world at the game India had invented.
Anand came from Chennai, a city with no chess tradition, no state-sponsored training programme, no Soviet-style sports academy. He learned the game from his mother. He practised at the Mikhail Tal Chess Club in Chennai. He rose through sheer talent and determination in a country where chess received virtually no government funding, no media coverage, and no public recognition.
His success triggered an explosion. The NIIT Mind Champions Academy, launched in 2006, took chess into schools across India, reaching millions of children. State governments began funding chess programmes. Corporate sponsors appeared. Online platforms, Chess.com, Lichess, made high-level training accessible to anyone with an internet connection.
The numbers tell the story:
- 1988, India has 1 grandmaster (Anand)
- 2000, India has 8 grandmasters
- 2010, India has 27 grandmasters
- 2020, India has 65 grandmasters
- 2026, India has 85+ grandmasters, second only to Russia
The COVID-19 pandemic, paradoxically, accelerated India’s chess revolution. With schools closed and children at home, millions discovered online chess. India’s young population, with widespread smartphone access and affordable internet, created a massive pool of new players. During lockdown, India accounted for the largest growth in Chess.com registrations of any country.
The result is a generation of Indian prodigies that the chess world has never seen:
- Gukesh Dommaraju, World Champion at 18, the youngest in history
- Rameshbabu Praggnanandhaa, Became India’s youngest International Master at 10 and Grandmaster at 12, defeated Magnus Carlsen in rapid and classical formats
- Arjun Erigaisi, Entered the world top 10 at age 21, known for aggressive, creative play
- Koneru Humpy, World Rapid Champion 2019, one of the strongest female players in history
- Vaishali Rameshbabu, Praggnanandhaa’s sister, became a Grandmaster in 2024, making them the first brother-sister GM pair in history
What distinguishes India’s chess revolution from the Soviet model is its democratic character. Soviet chess was state-sponsored, centrally organised, and elite-driven. Indian chess is chaotic, grassroots, and driven by individual passion. Grandmasters are emerging from small towns, Nashik, Sivakasi, Salem, not just metropolitan centres. Online coaching has democratised access. A kid with a phone and a dream can now train with International Masters for a few hundred rupees a month.
The Khelo India programme has added chess to its list of supported sports, providing financial support to promising young players. The All India Chess Federation has expanded its tournament calendar. India won the gold medal in the 2022 Chess Olympiad, held in Chennai, a symbolic homecoming for a game born on Indian soil.
The Bigger Picture
Chess may be India’s most successful cultural export. Consider how it spread: not through colonialism (unlike the English language), not through trade policy (unlike spices), not through religious conversion (unlike Buddhism to East Asia). Chess spread because it was a perfect game, balanced, deep, infinite in its possibilities, playable by anyone with a flat surface and a set of pieces.
It crossed the boundaries between Hindus and Muslims, Arabs and Europeans, Soviets and Americans. During the Cold War, chess was one of the few arenas where the superpowers competed face-to-face, mind against mind, and the game they competed with was Indian. Bobby Fischer and Boris Spassky sat down in Reykjavik in 1972 to play the game of Chaturanga.
Compare chess to India’s other great exports. Zero and the decimal number system transformed mathematics and commerce worldwide, but they spread through scholarly transmission, mediated by Arab mathematicians. Yoga spread through a complex process of cultural adaptation, commercialisation, and, frankly, distortion. Chess spread intact. The rules evolved, the pieces changed names, the strategies deepened, but the essential structure remained what it was in the Gupta courts: two armies, sixty-four squares, capture the king.
The irony of India’s relationship with chess is both painful and inspiring. India invented the game, then lost its competitive edge for over a millennium. While Persia, Arabia, and Europe developed chess theory, India’s chess tradition remained local and informal, played in homes and tea shops, not in academies and tournaments. The British colonized India but never acknowledged that the game their officers played in their clubs originated in the very country they were colonizing.
India’s reclamation of chess, from Anand’s lonely fight for recognition in the 1980s to Gukesh’s world championship in 2024, is about more than sport. It’s about intellectual sovereignty. It’s about a country rediscovering that its greatest contributions to civilisation aren’t behind it, they’re still unfolding.
Srinivasa Ramanujan saw mathematical truths that took the rest of the world decades to verify. India’s chess prodigies are doing something similar, seeing moves, patterns, and strategies that emerge from a tradition of abstract thinking stretching back to the Gupta Empire. The board hasn’t changed in 1,500 years. India’s ability to master it is finally catching up with its ability to create it.
Every time a child in India sets up the pieces and plays 1.e4, they are continuing something that began in the same civilisation that gave the world zero, that calculated pi, that built Nalanda, that sent its brightest minds to solve problems the rest of the world hadn’t yet imagined. Chess is not just India’s game. It’s proof that India’s greatest ideas are the ones that belong to everyone.
