Introduction & Preface

  • The Laws of Chess are divided into two parts: 1. Basic Rules of Play (Articles 1–5) and 2. Competitive Rules of Play (Articles 6–12).
  • The English text is the authentic version of the Laws as adopted by the FIDE Congress.
  • Arbiters must possess competence, sound judgment, and absolute objectivity. The laws cannot cover every possible situation, so analogous situations should be studied.
  • A necessary condition for a game to be rated by FIDE is that it shall be played according to these Laws.
Article 1: Nature & Objectives
  • The game is played between two opponents on a square 'chessboard' with 64 squares.
  • White moves first, followed by Black. Players move alternately.
  • A player 'has the move' when the opponent's move has been 'made'.
  • Objective: Place the opponent's king 'under attack' (check) such that the opponent has no legal move (checkmate).
  • Leaving one's own king under attack, exposing it to attack, or capturing the opponent's king is illegal.
Article 2: Initial Position
  • Board: 8×8 grid. Orientation: White square in the right-hand corner nearest the player.
  • Files: 8 vertical columns. Ranks: 8 horizontal rows. Diagonals: Lines of same-colored squares.
  • Pieces per player: 1 King (K), 1 Queen (Q), 2 Rooks (R), 2 Bishops (B), 2 Knights (N), 8 Pawns.
  • Initial Setup: Rooks in corners, Knights next, Bishops next. Queen on her own color, King on remaining square.
Article 3: Moves of Pieces
  • Bishop: Diagonals only. Rook: Files and Ranks. Queen: Files, Ranks, or Diagonals.
  • Knight: 'L' shape (two squares one way, then one square to the side). Can jump over pieces.
  • Pawn: Forward 1 square. Option to move 2 squares on the first move. Captures diagonally forward.
  • En Passant: If a pawn moves 2 squares and lands beside an opponent's pawn, it can be captured as if it moved 1 square (next move only).
  • Promotion: When a pawn reaches the furthest rank, it must be exchanged for a Q, R, B, or N of the same color.
  • King: One square in any direction.
  • Castling: King moves 2 squares towards a rook, rook jumps over king. ILLEGAL IF: King/Rook has moved, King is in check, King crosses or lands on a square under attack.
Article 4: Moving Pieces
  • Each move must be played with one hand only.
  • Touch-Move: If you touch your own piece, you MUST move it (if legal).
  • Touch-Capture: If you touch an opponent's piece, you MUST capture it (if legal).
  • J'adoube: You must announce 'I adjust' BEFORE touching a piece to adjust its position without intent to move.
  • Completion: A move is made when the piece is released on the board. Once released, it cannot be moved to another square.
Article 5: Completion of the Game
  • Win: By Checkmate (King attacked with no escape) or Resignation (opponent gives up).
  • Draw (Stalemate): Player to move has NO legal moves, but King is NOT in check.
  • Draw (Dead Position): A position where neither player can checkmate (e.g. K vs K, K+B vs K).
  • Draw (Agreement): Players may agree to a draw during the game (after a move is made).
  • Loss: If a player runs out of time (Flag Fall), provided opponent has mating material. Otherwise it is a draw.
Article 6: The Chess Clock
  • A move is only completed for the clock's purpose after the player has pressed their clock.
  • Players must press the clock with the SAME hand used to make the move.
  • Flag Fall: If the allotted time expires, the player loses the game.
  • Exception: If the opponent cannot checkmate by any possible series of legal moves, the game is drawn.
  • The arbiter decides where the clock is placed.
Article 7: Irregularities
  • Restoration: If an illegal move is found during the game, the position is reinstated to before the irregularity.
  • Illegal Move Actions: Moving a piece illegally, pawn promotion without replacing pawn, pressing clock without moving, using two hands.
  • First Penalty: For the first completed illegal move, the arbiter gives the opponent TWO minutes extra time.
  • Second Penalty: For the second completed illegal move by the same player, the arbiter declares the game LOST by the offender.
  • Displaced Pieces: Player must recreate position on their own time.
Article 8: Recording Moves
  • Algebraic notation is mandatory (e.g., Be5, Nf3, exd5).
  • Forbidden to record moves in advance (except when claiming a draw or adjourning).
  • A player may reply to a move before recording it, but must record their previous move before making the next.
  • Scoresheet must be visible to the arbiter.
  • If less than 5 minutes remain (and no 30s increment), recording is not mandatory but must be updated after flag fall.
Article 9: Drawn Games
  • Draw Offers: Must be made after moving on the board but before pressing the clock. Mark with (=).
  • 3-Fold Repetition (Claim): Player can CLAIM a draw if the same position appears for the 3rd time (same player to move, same rights).
  • 50-Move Rule (Claim): Player can CLAIM a draw if 50 moves have passed without a pawn move or capture.
  • Mandatory Draw: The game is drawn automatically if a position occurs 5 times or 75 moves pass without pawn move/capture.
Article 11: Conduct
  • Players shall take no action that brings the game into disrepute.
  • Playing Venue: Players may not leave the 'playing venue' without permission.
  • Electronic Devices: STRICTLY FORBIDDEN. If found with a mobile phone/device on their person, the player LOSES immediately.
  • Distraction: It is forbidden to distract or annoy the opponent (includes unreasonable draw offers).
  • Smoking/Vaping: Permitted only in designated areas.
Article 12: The Arbiter
  • Duties: Ensure fair play, supervise the competition, ensure good playing environment.
  • Non-Intervention: Arbiter generally does not intervene in the game unless an irregularity occurs.
  • Penalties available: Warning, increasing opponent's time, reducing offender's time, declaring game lost, fine, expulsion.
  • Spectators: Arbiters may expel offenders from the venue.
Appendices (Rapid & Blitz)

  • Blitz Chess: 10 min or less per player.
  • Penalties (Rapid/Blitz): Penalties for illegal moves are often 1 minute instead of 2 minutes.
