What is Chess?

Chess is one of the world's oldest and most-studied strategy games. Its ancestor, chaturanga, emerged in India around the 6th century and evolved through Persian shatranj into modern chess in 15th-century southern Europe. Two players — White and Black — command 16 pieces each and alternate moves on a 64-square board. Governed by FIDE, chess is now considered a mind sport by the IOC, played at professional level with time controls ranging from 1-minute bullet to 7-hour classical games.

How it works

Objective

Checkmate your opponent's king — put it under attack with no legal move to escape.

Match structure

White moves first; players alternate one move per turn. A game ends by checkmate, resignation, draw by agreement, stalemate, threefold repetition, the 50-move rule or timeout.

Rules

Basic rules

  • Movement

    Rook: any number of squares in a straight line. Bishop: diagonals. Queen: rook + bishop combined. Knight: L-shape (2+1), jumps over pieces. King: one square any direction. Pawn: one square forward (two on first move), captures diagonally.

  • Check & checkmate

    'Check' is a direct threat to the king. 'Checkmate' is a check the king cannot escape — game over.

  • Castling

    The king moves two squares toward a rook and the rook jumps to the king's other side. Only allowed if neither piece has moved, no squares between are occupied, and the king is not in / does not pass through check.

  • En passant

    A pawn that advances two squares can be captured 'in passing' by an enemy pawn on the very next move.

  • Promotion

    A pawn reaching the last rank promotes — most commonly to a queen, but any piece except a king is allowed.

  • Draw conditions

    Stalemate (no legal move but not in check), threefold repetition, 50-move rule (no capture / pawn move), insufficient material or mutual agreement.

Scoring

1 point for a win, ½ for a draw, 0 for a loss. Round-robin totals decide tournament standings; Swiss pairings and tiebreaks handle everything else.

Win condition · Checkmate, resignation, or opponent's flag falling on the clock (win on time).

Playing area

Dimensions

8 × 8 = 64 alternating light and dark squares.

The board is oriented so each player has a light-coloured square in the bottom-right corner.

Equipment

  • Chessboard

    8×8 grid, 64 squares in two alternating colours.

  • 32 pieces

    Each side: 1 king, 1 queen, 2 rooks, 2 bishops, 2 knights, 8 pawns.

  • Clock

    Two-faced clock, mandatory in competitive play; players press it after each move.

  • Scoresheet

    For notating games in algebraic notation.

Positions & roles

  • King

    ×1

    Must be protected — game ends if it is checkmated.

  • Queen

    ×1

    Most powerful piece — moves like a rook and bishop combined.

  • Rook

    ×2

    Moves any number of squares in a straight line.

  • Bishop

    ×2

    Moves diagonally — one per colour of square.

  • Knight

    ×2

    L-shaped move; only piece that can jump.

  • Pawn

    ×8

    Slow but many; promotes at the last rank.

Officiating

In official play a certified arbiter oversees the game; players may summon the arbiter at any time.

  • Arbiter — enforces rules, resolves disputes, monitors clocks

Penalties & fouls

Penalties

  • Illegal move

    First illegal move → opponent gets extra time. Second → automatic loss.

  • Touch-move

    Touch a piece, you must move it. Touch an opponent's piece, you must capture it — if legal.

Terminology

Fork
A single move that attacks two enemy pieces at once — typically by a knight.
Pin
A piece is 'pinned' if moving it would expose a more valuable piece behind it.
Zugzwang
A position in which any move a player makes worsens their position.
Zwischenzug
An 'in-between move' that ignores an apparent obligation to force a stronger reply.
Endgame
The final phase of the game, typically with few pieces left.
Elo
The rating system used to measure a player's strength — introduced by Arpad Elo in 1960.
