What Is Chess?

Chess is a two-player strategy board game played on an 8×8 grid of 64 alternating light and dark squares. Each player commands an army of 16 pieces with the goal of trapping the opponent’s King in an inescapable attack called checkmate.

Chess is one of the oldest and most popular games in human history, with origins dating back over 1,500 years. It is played by hundreds of millions of people worldwide, from casual kitchen-table games to elite international tournaments with world championship titles.

What makes chess unique is that it is a game of pure strategy — there is no luck, no dice, no hidden information. Every piece is visible, every option is open, and the better strategist wins. Yet despite simple rules, chess offers virtually infinite complexity. There are more possible chess games than atoms in the observable universe.


Setting Up the Board

Board Orientation

Place the board so that each player has a light square in the bottom-right corner. An easy way to remember: “light on right.”

Piece Placement

Starting from the corner and working inward along the back row (called the first rank):

Position Piece
Corners (a1, h1) Rooks
Next to Rooks (b1, g1) Knights
Next to Knights (c1, f1) Bishops
d1 Queen
e1 King

The entire second rank is filled with Pawns.

Black’s pieces mirror White’s on the opposite side of the board.

Tip: The Queen always starts on her own color — the White Queen on a light square (d1), the Black Queen on a dark square (d8). Remember: “Queen on her color.”


How Each Piece Moves

King ♔ ♚

The King moves one square in any direction — horizontally, vertically, or diagonally. Despite being the most important piece, the King is one of the weakest in terms of movement.

The King can never move to a square that is attacked by an enemy piece. The King’s safety is the entire point of the game.

Queen ♕ ♛

The Queen is the most powerful piece. She can move any number of squares in any direction — horizontally, vertically, or diagonally. She combines the movement of the Rook and Bishop.

Rook ♖ ♜

The Rook moves any number of squares horizontally or vertically (along ranks and files). Rooks are most powerful in the endgame and on open files (columns with no pawns).

Bishop ♗ ♝

The Bishop moves any number of squares diagonally. Each player starts with two Bishops — one on light squares and one on dark squares. A Bishop stays on its starting color for the entire game.

Knight ♘ ♞

The Knight moves in an L-shape: two squares in one direction and one square perpendicular (or vice versa). The Knight is the only piece that can jump over other pieces.

Knights are especially useful in the opening and middlegame when the board is crowded. They are strongest in closed positions with many pawns blocking straight-line pieces.

Pawn ♙ ♟

Pawns are the most numerous and move differently than any other piece:

  • Forward movement: Pawns move one square forward (toward the opponent’s side). They cannot move backward.
  • First move: On their first move only, pawns can advance two squares forward.
  • Capturing: Pawns capture one square diagonally forward — they cannot capture by moving straight ahead.

Pawns have two special rules covered in the next section: promotion and en passant.


Special Rules

Castling

Castling is a special move involving the King and one Rook. It is the only move in chess where two pieces move at once. Castling allows you to:

  1. Move the King to safety
  2. Activate the Rook

How to castle: The King moves two squares toward a Rook, and the Rook moves to the square the King crossed.

  • Kingside castling (short): King moves from e1 to g1, Rook moves from h1 to f1
  • Queenside castling (long): King moves from e1 to c1, Rook moves from a1 to d1

Requirements for castling:

  • Neither the King nor the Rook has moved previously
  • No pieces between the King and Rook
  • The King is not currently in check
  • The King does not pass through or land on a square attacked by an enemy piece

En Passant

En passant (“in passing” in French) is a special pawn capture. When an opponent’s pawn advances two squares from its starting position and lands beside your pawn, you can capture it as if it had only moved one square.

This capture must be made immediately on the next move or the right is lost.

Pawn Promotion

When a pawn reaches the far side of the board (the 8th rank for White, the 1st rank for Black), it must be promoted to another piece: Queen, Rook, Bishop, or Knight. Most players promote to a Queen. Promotion to a lesser piece is called underpromotion and is sometimes strategically useful.


Check, Checkmate, and Draws

Check

A King is in check when an enemy piece directly attacks it. When you are in check, you must get out of check on your next move by:

  1. Moving the King to a safe square
  2. Blocking the attack by placing a piece between the King and attacker
  3. Capturing the attacking piece

Checkmate

Checkmate ends the game. It occurs when a King is in check and there is no legal move to escape. The player who delivers checkmate wins.

Stalemate (Draw)

Stalemate occurs when a player is not in check but has no legal move. This is a draw — neither player wins.

Other Draws

  • Insufficient material: Neither side has enough pieces to force checkmate (e.g., King vs. King)
  • Threefold repetition: The same board position occurs three times
  • 50-move rule: 50 consecutive moves by each side with no capture and no pawn move
  • Agreement: Both players agree to a draw

Basic Piece Values

Chess pieces have approximate point values to help evaluate trades:

Piece Value
Pawn 1 point
Knight 3 points
Bishop 3 points
Rook 5 points
Queen 9 points
King Invaluable

These values are guidelines, not absolutes. A well-positioned Knight can be worth more than a passive Rook. Context always matters.

Tip: Avoid trading a Rook (5 points) for a Knight or Bishop (3 points) — that is a bad trade. Trading a Knight for a Bishop is generally even.


Your First Game Tips

  1. Control the center — move pawns to e4 and d4 early to claim space
  2. Develop your pieces — get Knights and Bishops off the back row quickly
  3. Castle early — tuck your King to safety, usually within the first 10 moves
  4. Don’t move the same piece twice in the opening unless necessary
  5. Don’t bring your Queen out too early — she can be chased around by smaller pieces
  6. Think about your opponent’s threats before making your move
  7. Try not to move too many pawns — focus on getting your pieces active
