Chess is a two-player strategy game contested on a 64-square board, and its modern rules have stood essentially unchanged for centuries. The goal is simple to state: attack the enemy king so that it cannot escape — that is checkmate. This guide walks you through the official rules step by step, from the starting setup and piece movement to castling, en passant, promotion and the ways a game can end in a draw.

The Board and Starting Position

The board has 8 files and 8 ranks and is placed so that each player has a light square in the near right-hand corner. Both sides begin with 16 pieces: 8 pawns, 2 rooks, 2 knights, 2 bishops, 1 queen and 1 king. The rooks go in the corners, the knights beside them, then the bishops; the queen starts on a square of her own colour and the king takes the remaining central square. White always moves first, and the players then alternate one move at a time — passing a turn is never allowed.

How the Pieces Move

  • Pawn: moves one square straight forward, or optionally two squares on its very first move. It captures one square diagonally forward and can never move backwards.
  • Rook: moves any number of empty squares horizontally or vertically.
  • Bishop: moves any number of empty squares diagonally and stays on the same colour for the whole game.
  • Knight: moves in an "L" shape — two squares straight, then one to the side — and is the only piece that can jump over others.
  • Queen: combines the powers of the rook and the bishop; the strongest piece on the board.
  • King: moves one square in any direction and may never step onto a square attacked by an enemy piece.

Check, Checkmate and Stalemate

When your king is attacked, it is in check, and you must deal with the threat immediately: move the king to a safe square, block the attack, or capture the attacking piece. If none of those three options exists, it is checkmate — the game ends and the attacking side wins. Stalemate is different: the player to move has no legal move at all, yet the king is not in check. A stalemated game is a draw, which is why careless play in a winning position can throw away half a point.

Special Moves

Castling

Castling is the only move in which two pieces move at once: the king slides two squares towards a rook, and that rook jumps to the square beside the king. Castling towards the king's side is called short castling; towards the queen's side, long castling. The conditions are strict: neither the king nor that rook may have moved before, the squares between them must be empty, the king may not currently be in check, and the king may not pass through or land on any attacked square.

En Passant

If an enemy pawn advances two squares from its starting square and lands directly beside your pawn, you may capture it as if it had moved only one square. This right lasts for exactly one move — if you do not use it immediately, it is gone for good.

Pawn Promotion

A pawn that reaches the last rank leaves the board and becomes any piece its owner chooses: a queen, rook, bishop or knight. Players almost always choose a queen, and yes — you can have more than one queen on the board at the same time.

How Games Are Drawn

  • Stalemate: the side to move has no legal move and is not in check.
  • Threefold repetition: the same position, with the same player to move, occurs three times.
  • Fifty-move rule: fifty consecutive moves pass with no capture and no pawn move.
  • Insufficient material: neither side has enough pieces left to deliver checkmate, such as bare king against bare king.

Three Tips for New Players

Fight for the central squares, bring your knights and bishops into play quickly, and castle to tuck your king into safety. Before every move, ask yourself one question: "What did my opponent's last move threaten?" Once the rules are learned, nothing teaches faster than playing plenty of games — the rules soon turn into instinct.
