Chess is the world's most played board game, and its rules are simple enough to learn in an afternoon — yet the game has no ceiling. Two players, sixteen pieces each, three phases, and a single objective: trap the enemy king. Everything else in chess, from the great rivalries to the online boom, is built on that frame.

How the Sport Works

Chess is played on an 8-by-8 board of 64 squares. Each player begins with 16 pieces: one king, one queen, two rooks, two bishops, two knights and eight pawns. White moves first, and the players alternate moves.

Each piece moves differently. The king moves one square in any direction. The queen moves any distance along a rank, file or diagonal, making her the most powerful piece. Rooks move any distance in straight lines, bishops move any distance diagonally, and knights jump in an L-shape — two squares in one direction and one to the side — and are the only pieces that can jump over others. Pawns move forward one square, capture diagonally, and can move two squares on their first move.

Three special moves complete the rules. Castling lets the king and a rook move together to safety, and is allowed only if neither piece has moved, the squares between them are clear, and the king is not in check or passing through an attacked square. En passant allows a pawn to capture an opposing pawn that has just moved two squares, as if it had moved only one. And a pawn that reaches the far side of the board is promoted, usually to a queen.

The objective is checkmate: placing the enemy king in check — under attack — with no legal escape. A player also wins if the opponent resigns or, in a timed game, runs out of time.

Scoring: Wins, Draws and the Clock

A win scores one point, a draw half a point for each player, and a loss zero. Draws are common at the top level and rarer among beginners. A game can be drawn by stalemate — when the player to move has no legal move but is not in check — by threefold repetition of the same position, by the 50-move rule when no pawn has moved and no capture has been made for fifty moves, by agreement, or when neither side has enough material left to deliver checkmate.

In competition, almost every game is played with a time control, shown as base time plus increment. The increment adds a few seconds to a player's clock after every move. The four categories are bullet, blitz, rapid and classical. Bullet gives each player under three minutes for the whole game, usually one or two minutes. Blitz is three to ten minutes per player. Rapid is ten to sixty minutes. Classical gives sixty minutes or more per player, and elite classical games can run for four to six hours.

If a player's clock reaches zero, they lose on time — unless the opponent has no possible sequence of legal moves that could deliver checkmate, in which case the game is drawn.

Formats and Major Competitions

The pinnacle of the sport is the FIDE World Championship, held every two years as a match, currently played over 14 classical games with tiebreaks if needed. FIDE, the International Chess Federation, has regulated the championship since 1948 and also awards lifetime titles, the highest of which is Grandmaster.

Tournament formats are usually round-robin, where everyone plays everyone, or Swiss, where players are paired against opponents on a similar score and nobody is eliminated after a loss. FIDE also organises the Women's World Championship, the World Rapid and Blitz Championships, the World Junior Championship and the Chess Olympiad, the popular team competition between national sides.

Online, chess has become one of the most watched games in the world, with millions of players on the major platforms and a professional circuit of rapid and blitz events that runs alongside the classical calendar.

A Brief History

Chess evolved from earlier board games played in India and Persia more than a thousand years ago, and reached its modern form in Europe in the fifteenth century, when the queen and bishop gained their current powers. The first generally recognised World Chess Champion, Wilhelm Steinitz, claimed his title in 1886.

The twentieth century professionalised the game: FIDE took control of the championship in 1948, the Soviet school dominated for decades, and the 1972 match between Bobby Fischer and Boris Spassky turned chess into a global media event. The computer age followed, and the online boom of the 2020s made chess one of the most streamed and played games on the internet.

How to Follow It

The best way into chess is to play it: ten-minute rapid games are the sweet spot for learning, fast enough to stay sharp and slow enough to think. To watch, the World Championship match is the place to start — two players, two weeks, and every move analysed live by commentators and engines.

For daily drama, the rapid and blitz circuit is faster and more volatile, and the Olympiad is the sport's great team festival, where the world's best play for their countries. And whatever the format, the rule is the same: the player who makes the second-to-last mistake usually wins.
