Rules

Basic Chess Rules

1. Objective: The objective of chess is to checkmate your opponent’s king. Checkmate occurs when the opponent’s king is under attack and cannot escape capture.
2. Setup: The board consists of 64 squares arranged in an 8×8 grid. Each player starts with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. The pieces are set up on the first two rows of the board, with pawns on the second row and other pieces on the first row.
3. Movement: Each type of piece moves differently:
   • The king moves one square in any direction.
   • The queen moves any number of squares horizontally, vertically, or diagonally.
   • The rook moves any number of squares horizontally or vertically.
   • The knight moves in an “L” shape: two squares in one direction (horizontally or vertically), and then one square perpendicular to that.
   • The bishop moves any number of squares diagonally.
   • The pawn moves forward one square, but on its first move, it has the option to move forward two squares. Pawns capture diagonally.
4. Special Moves:
   • Castling: The king moves two squares towards a rook on its first rank, then the rook moves to the square next to the king. Castling can only be done if neither the king nor the rook has moved before, there are no pieces between them, and the king is not in check or would move through or into check.
   • En passant: If a pawn moves two squares forward from its starting position and lands beside an opponent’s pawn, the opponent has the option to capture it “en passant,” as if the moving pawn had only moved one square forward.
   • Pawn Promotion: If a pawn reaches the opposite side of the board, it can be promoted to any other piece (except a king).
5. Check and Checkmate:
   • Check occurs when a player’s king is under threat of capture.
   • Checkmate occurs when a player’s king is in check and there is no legal move to remove the threat. The game ends immediately, and the player in checkmate loses.
6. Draws:
   • Draws can occur by stalemate (when a player has no legal moves and is not in check), insufficient material (when neither player has enough pieces to checkmate), threefold repetition (when the same position occurs three times with the same player to move), or the fifty-move rule (when no pawn has moved and no capture has been made in the last fifty moves by each player).

FIDE Chess Rules

The FIDE (Fédération Internationale des Échecs) rules for chess are the standard rules used in most official chess competitions worldwide. Here’s a summary of the key points:

1. Board and Setup: The game is played on an 8×8 grid board with alternating light and dark squares. Each player has 16 pieces, including a king, a queen, two rooks, two knights, two bishops, and eight pawns, arranged on the first two rows of the board.
2. Movement of Pieces: Each type of piece has its own unique way of moving:
   • The king moves one square in any direction.
   • The queen moves any number of squares diagonally, horizontally, or vertically.
   • The rook moves any number of squares horizontally or vertically.
   • The knight moves in an “L” shape: two squares in one direction (horizontally or vertically), and then one square perpendicular to that.
   • The bishop moves any number of squares diagonally.
   • The pawn moves forward one square, but on its first move, it has the option to move forward two squares. Pawns capture diagonally.
3. Castling: A special move involving the king and one of the rooks, where the king moves two squares towards a rook on its starting rank, and the rook moves to the square next to the king. Castling is subject to certain conditions, including that neither the king nor the rook involved has previously moved, and that the squares between the king and rook are unoccupied.
4. En passant: A special pawn capture that can occur when a pawn moves two squares forward from its starting position and lands beside an opponent’s pawn. The opponent has the option to capture the pawn “en passant,” as if it had only moved one square forward.
5. Pawn Promotion: When a pawn reaches the opposite side of the board, it can be promoted to any other piece (except a king).
6. Check and Checkmate: A player’s king is in “check” when it is under threat of capture by the opponent’s pieces. If a player’s king is in check and there is no legal move to remove the threat, it is in “checkmate,” and the game ends with that player losing.
7. Draws: Draws can occur by various means, including stalemate (when a player has no legal moves and is not in check), threefold repetition (when the same position occurs three times with the same player to move), the fifty-move rule (when no pawn has moved and no capture has been made in the last fifty moves by each player), and insufficient material (when neither player has enough pieces to checkmate).

These rules provide the framework for standard chess play and are used in FIDE-sanctioned tournaments and competitions around the world.
