Chess
A two-player strategy game on an 8×8 board — checkmate the enemy king before your own falls.
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).
