Chess: The Complete Guide to Rules, History, and World Records
Chess is often called the "Game of Kings" — a two-player strategy board game that has captivated minds for over 1,500 years. Whether you are learning chess rules for the first time, researching the history of chess for a school project, or curious about the greatest chess records ever set, this guide brings together everything in one comprehensive reference.

1. The Rules of Chess
Chess is played on an 8×8 board of 64 alternating light and dark squares by two players, traditionally called White and Black. Each side begins with 16 pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns. The objective of the game is to checkmate the opponent's king — placing it under an inescapable attack.
Board Setup
The board is oriented so each player has a white (light) square in the bottom-right corner. Pawns occupy the second rank for each side, and back-rank pieces are arranged as: Rook–Knight–Bishop–Queen–King–Bishop–Knight–Rook. A useful memory rule is "queen on her own color" — the white queen starts on a light square (d1), the black queen on a dark square (d8).
How Each Piece Moves
Special Moves
- Castling: A one-time move involving the king and a rook, allowing the king to move two squares toward a rook while that rook jumps to the square beside the king. Castling is only legal if neither piece has previously moved, no pieces stand between them, and the king is not in, through, or into check.
- En Passant: A special pawn capture. If a pawn moves two squares forward from its starting square and lands beside an enemy pawn, that enemy pawn may capture it "in passing" as if it had only moved one square — but only on the very next move.
- Pawn Promotion: When a pawn reaches the opposite end of the board (the 8th rank for White, 1st rank for Black), it must be promoted to a queen, rook, bishop, or knight of the same color.
Check, Checkmate, and Draws
A king is in check when it is under direct attack. The player must immediately remove the check by moving the king, blocking the attack, or capturing the attacking piece. If no legal move can remove the check, it is checkmate and the game ends immediately — the checkmated player loses.
A game can also end in a draw through several outcomes:
- Stalemate: The player to move has no legal move and is not in check.
- Threefold repetition: The identical position occurs three times with the same player to move.
- Fifty-move rule: No pawn has moved and no capture has occurred in the last 50 moves by each side.
- Insufficient material: Neither side has enough pieces left to deliver checkmate (e.g., king vs. king).
- Mutual agreement: Both players agree to a draw.
Basic Chess Notation
Chess moves are recorded using algebraic notation. Files (columns) are lettered a–h and ranks (rows) numbered 1–8, so every square has a unique coordinate (e.g., e4, d5). Piece abbreviations are K (king), Q (queen), R (rook), B (bishop), N (knight); pawns have no letter. Captures are marked with "x", check with "+", and checkmate with "#" — for example, Nxf7+ means a knight captures on f7 with check.
2. The History of Chess
2.1 Ancient Origins: Chaturanga (6th Century India)
The history of chess begins in northern India around the 6th century CE with a game called Chaturanga, meaning "four divisions of the military" — infantry, cavalry, elephantry, and chariotry, which evolved into the modern pawn, knight, bishop, and rook. Chaturanga was played on an 8×8 uncheckered board known as an ashtapada and already contained the conceptual seed of a king-capturing objective.
2.2 Persia and the Islamic Golden Age: Shatranj
Chaturanga traveled to Sassanid Persia by around 600 CE, where it was adapted into Shatranj. The word "checkmate" itself derives from the Persian phrase shah mat, meaning "the king is helpless" or "the king is dead." Following the Islamic conquest of Persia in the 7th century, Shatranj spread rapidly across the Islamic world, from Spain to Central Asia, and produced some of history's earliest recorded chess theorists, including al-Adli ar-Rumi (9th century), author of one of the first known chess treatises.
2.3 Arrival in Europe and the Birth of Modern Chess
Chess reached Europe via the Moorish conquest of Spain and Byzantine trade routes by the 10th century, spreading through Italy, France, and beyond by the 11th–13th centuries. The game underwent its most significant transformation in late 15th-century Spain and Italy, when the queen and bishop were given their modern, far more powerful moves — the queen changing from a weak short-range piece to the most powerful piece on the board. This version, sometimes called "Mad Queen Chess," is essentially the game played today.
2.4 The Age of Chess Theory (16th–19th Century)
The 16th century produced influential theorists such as Ruy López de Segura, whose 1561 treatise analyzed openings still named after him (the Ruy Lopez / Spanish Opening). By the 18th and 19th centuries, chess clubs and coffeehouse culture flourished in Paris and London. François-André Danican Philidor, considered the strongest player of the 18th century, famously declared "pawns are the soul of chess." The 19th century saw the rise of Paul Morphy, an American prodigy whose brilliant, rapid attacking style made him the unofficial world's strongest player in the late 1850s.
2.5 The World Championship Era and FIDE
The first official World Chess Championship was contested in 1886 between Wilhelm Steinitz and Johannes Zukertort, with Steinitz winning to become the first universally recognized World Champion. In 1924, the Fédération Internationale des Échecs (FIDE) was founded in Paris to govern international chess, standardize rules, and organize world championships and Olympiads. FIDE remains the sport's global governing body today, overseeing the official Elo rating system and titles such as Grandmaster (GM), International Master (IM), and Woman Grandmaster (WGM).

2.7 The Computer Chess Revolution
In May 1997, IBM's supercomputer Deep Blue defeated reigning World Champion Garry Kasparov in a six-game match — the first time a computer defeated a world champion under standard time controls, a landmark moment in artificial intelligence history. Chess engines have since surpassed human ability entirely; modern neural-network engines such as Stockfish and Google DeepMind's AlphaZero (2017) play at a level far beyond any human, reshaping how professionals study and prepare openings today.
2.8 The Online Chess Boom
Platforms such as Chess.com and Lichess, alongside events like the Netflix series "The Queen's Gambit" (2020), fueled an unprecedented global surge in chess popularity during the 2020s. Online play, streaming, and rapid/blitz formats have introduced the game to millions of new players worldwide — a tradition that portals like Randomove continue by making classic games instantly accessible in the browser.
