Official Chess Rules & Mechanics
Everything you need to play legal, confident chess according to official FIDE regulations. Explore interactive step-by-step diagrams for piece movement, special mechanics, and endgame rules.
Piece Movement & Powers
Master how each individual piece maneuvers, attacks, and controls squares on the board.
How the King Moves
The King is the most vital piece in chess; it moves exactly 1 square in any direction and can never move into danger.
How the Queen Moves
Combining the full powers of both the Rook and the Bishop, the Queen is the single most powerful attacking piece in chess.
How the Rook Moves
Rooks move in straight orthogonal lines along ranks (rows) and files (columns) across any number of open squares.
How the Bishop Moves
Bishops glide diagonally across as many open squares as they choose, permanently bound to their starting square color.
How the Knight Moves
The Knight jumps in an iconic L-shape (2 squares one way, 1 square perpendicular) and is the only piece that can leap over others.
How the Pawn Moves
Pawns march straight forward one square, capture diagonally, have an optional initial two-square leap, and never move backward.
Special Moves & Mechanics
The unique FIDE rules that frequently surprise beginners: Castling, En Passant, and Pawn Promotion.
Castling
A special two-piece move that safely tucks the King away while simultaneously activating a Rook.
En Passant
A special capture rule allowing pawns to take an adjacent enemy pawn that just leaped two squares forward.
Pawn Promotion
When a pawn reaches the 8th rank, it instantly transforms into a Queen, Rook, Bishop, or Knight.
Check, Checkmate & King Attacks
Understand the objective of chess: threatening the king, escaping attacks, and delivering checkmate.
Check
A direct attack on the opponent's King that forces an immediate defense.
Checkmate
The ultimate goal of chess: putting the enemy King in an inescapable check to win the game.
Stalemate
A draw condition where a player has no legal moves and their King is NOT in check.
Draws & Game Endings
All 5 official ways a chess game ends in a draw: Stalemate, 50-move rule, threefold repetition, and more.
Board Setup & Tournament Rules
Official board orientation, coordinate systems, perspective shifts, and the strict Touch-Move rule.
How to Set Up a Chessboard
The official step-by-step setup for a chessboard: orientation, piece order, and the two golden rules.
The Chessboard from Black's Perspective
Understand how board coordinates and perspective shift when playing as Black: coordinates remain absolute while files and ranks flip visually.
Chess Ranks, Files & Diagonals
The 8×8 coordinate system that names all 64 squares on the chessboard using files (letters a–h) and ranks (numbers 1–8).
The Touch-Move Rule
The strict tournament rule requiring you to move or capture any piece you deliberately touch.
Frequently Asked Questions: Chess Rules
Quick, plain-English answers to common beginner and tournament rule questions.
What are the most important basic rules of chess?
The fundamental rules of chess govern piece movement (Pawns, Knights, Bishops, Rooks, Queen, King), board setup ('white on right', 'queen on color'), and the core objective: checkmating the opponent's king so it cannot escape attack.
What is the difference between Check, Checkmate, and Stalemate?
Check means the King is under direct attack but has a legal way to escape. Checkmate means the King is under attack with zero legal escape moves (Game Over, Attacker Wins). Stalemate means the King is NOT under attack, but the player has zero legal moves anywhere on the board (Draw / Tie, 0.5 - 0.5).
What are the 3 special moves in chess?
The three special moves in chess are: 1) Castling (moving King 2 squares toward Rook and Rook hopping over), 2) En Passant (capturing an enemy pawn in passing after its initial 2-square leap), and 3) Pawn Promotion (transforming a pawn reaching the 8th rank into a Queen, Rook, Bishop, or Knight).
How does a chess game end in a draw?
Under FIDE rules, a chess game is drawn by: 1) Stalemate, 2) Threefold Repetition, 3) 50-Move Rule (no pawn moves or captures), 4) Insufficient Material, or 5) Mutual Agreement between players.
