How to Play Chess

The Short Version

Chess is a two-player strategy game on an 8×8 board. Each side commands 16 pieces — one king, one queen, two rooks, two bishops, two knights, and eight pawns — and the players take turns moving one piece at a time. You win by checkmate: attacking the enemy king in a way it cannot escape. There is no luck and no hidden information; everything below is the complete legal game, including the three special moves and every way a game can end in a draw.

What You Need

A chess set and board — nothing else is required. A chess clock is optional equipment for timed games, not part of the basic rules. This page teaches legal play completely; it deliberately does not teach strategy, openings, or tactics beyond what the rules themselves define.

Set Up

Place the board so each player has a light-coloured square at their near right corner (‘white on right’). The back rank, from corner to corner, runs: rook, knight, bishop, queen, king, bishop, knight, rook. The queen sits on her own colour — the white queen on a light square, the black queen on a dark square — which puts the two queens facing each other and the kings facing each other. Eight pawns stand on the rank in front. White moves first.

A word on notation, since every chess book uses it: files (columns) are lettered a–h from White’s left, ranks (rows) numbered 1–8 from White’s side, so every square has a name like e4; a move is written with the piece’s letter (N for knight, since K is the king) plus the destination — Nf3 means a knight moved to f3, and O-O means castling.

How to Play

On your turn, move one of your pieces according to its pattern. You capture an enemy piece by landing on its square; the captured piece leaves the board. Except for the knight, no piece may jump over another — the path must be clear, and you may never land on a square occupied by your own piece. A move that leaves your own king under attack is illegal and must be taken back.

The king moves one square in any direction — horizontally, vertically, or diagonally. The king can never move into check (see below), which is why the two kings can never stand next to each other.

The queen moves any number of squares in a straight line or diagonally, as far as the path is clear. She is the strongest piece on the board precisely because nothing limits her range.

The rook moves any number of squares horizontally or vertically, never diagonally.

The bishop moves any number of squares diagonally, never straight. Each bishop therefore spends its whole life on one colour of square.

The knight moves in an L: two squares in one straight direction and one square to the side — or one and two, the same shape turned. The knight is the only piece that jumps; pieces in its way, friend or foe, don’t matter, only the landing square.

The pawn is the odd one. It moves forward one square into an empty square — never backward, never sideways. From its starting square only, it may move forward two squares if both are empty. It does not capture the way it moves: a pawn captures one square diagonally forward, and only that way. Everything else about pawns lives in the special moves below.

Special Moves

Castling is a single move that shifts your king and one rook at once, done to tuck the king away. Move the king two squares toward the rook, and the rook hops over to the square the king crossed. It is legal only if all of these hold: neither the king nor that rook has moved yet; every square between them is empty; the king is not currently in check; and the king neither passes through nor lands on a square attacked by an enemy piece. You may castle on either side, once per game. (Move the king first — in formal play, touching the rook first can commit you to a rook move instead.)

En passant is the capture everyone accuses their friend of inventing. If an enemy pawn uses its two-square opening move to land beside your pawn, you may capture it exactly as if it had moved only one square — your pawn moves diagonally to the square the enemy pawn passed over, and the enemy pawn comes off the board. The catch: you may do this only on the very next move. Decline, and the chance is gone forever.

Promotion: a pawn that reaches the far end of the board must immediately be exchanged for a queen, rook, bishop, or knight of the same colour — your choice, and almost always a queen. It may not stay a pawn, and it may not become a king. There is no limit: if you promote three pawns while your original queen still lives, you have four queens.

Check and Checkmate

Your king is in check when an enemy piece attacks its square. If you are in check, your move must get you out — you have exactly three kinds of escape: move the king to a safe square, capture the attacking piece, or (unless the attacker is a knight or right beside you) interpose a piece between attacker and king. A pinned piece — one shielding your king from a line piece — may be unable to move at all, since moving it would expose check.

Checkmate is check with no legal escape: the king cannot move away, the attacker cannot be captured, and the attack cannot be blocked. The game ends immediately and the side delivering checkmate wins. The king is never actually captured — the game stops one move before that could happen.

Winning

Win by checkmate, as above. You also win if your opponent resigns, which players do when mate is clearly unstoppable; in a timed game, you win if your opponent’s clock flag falls — unless you have no possible mating material left at all, in which case it’s a draw. And that is the complete list: there is no points system, no capturing-the-most-pieces win, and no bonus for promoting.

Draws — the Complete List

A game neither side can quite win usually ends level, and chess names every route:

• By agreement. Either player may offer a draw on their turn; if the opponent accepts, the game is drawn. Legal at any point.
• Stalemate. If the player to move is not in check but has no legal move at all — every square the king might take is attacked, and no other piece can move — the game is a draw. Stalemate is the defender’s last miracle and the attacker’s classic blunder: an overwhelming army can still only draw if it carelessly freezes the lone king without checking it.
• Insufficient material. Neither side can possibly deliver checkmate with what remains: king against king; king and bishop against king; king and knight against king; or king and bishop against king and bishop where both bishops travel on the same colour. The game is drawn — no legal sequence of moves could produce mate.
• Fifty-move rule. If fifty moves by each side pass with no pawn move and no capture, either player may claim a draw. (In formal tournament play, at seventy-five such moves the arbiter declares the draw automatically.)
• Threefold repetition. If the same position — same pieces, same player to move, same legal options — occurs for the third time, the player to move may claim a draw. Five occurrences end the game automatically in formal play.

Variations Worth Knowing

Timed chess (blitz and rapid) is the same game against a clock: each player has a total time budget, presses the clock after every move, and loses if their time runs out (subject to the mating-material exception above). Five minutes per side is the classic blitz game.

Chess960 (Fischer Random) shuffles the back-rank pieces into one of 960 legal starting arrangements, with castling adapted so the king and rook end on the same squares as in normal chess. Every movement rule on this page applies unchanged.

Takebacks and touch-move are etiquette, not rules of the game itself — they live in this page’s house rules box above because tables genuinely differ, and agreeing them in advance saves the only arguments casual chess really produces.
