How to play Chess
Chess originated in the Gupta Empire of northern India around the 6th century CE as chaturanga — four divisions of the military: infantry (pawns), cavalry (knights), elephants (bishops), and chariots (rooks). It spread to Persia as shatranj, then reached Europe via the Islamic world by the 9th–10th centuries. The modern rules — including the queen's expanded movement, en passant, and castling — crystallized in 15th-century Spain and Italy.
How Pieces Move
Each piece moves differently. The king moves one square in any direction. The queen moves any number of squares diagonally, horizontally, or vertically — the most powerful piece. Rooks move any number of squares horizontally or vertically. Bishops move diagonally and stay on the same color. Knights move in an L-shape (two squares in one direction, one perpendicular) and are the only pieces that can jump over others. Pawns move forward one square (or two from their starting rank) and capture diagonally.
Special Moves
Castling: the king moves two squares toward a rook and the rook jumps to the other side of the king. Allowed only if neither piece has moved, the path is clear, and the king is not in check. En passant: if a pawn advances two squares from its starting position and passes an enemy pawn that could have captured it one square in, the enemy pawn may capture it as if it had moved only one square — but only immediately. Promotion: a pawn reaching the opposite back rank immediately becomes any piece (almost always a queen).
Draw Conditions
A game is drawn in five ways: stalemate (the player to move has no legal moves but is not in check), threefold repetition (the same position occurs three times with the same player to move), the 50-move rule (50 consecutive moves by each player with no capture or pawn move), insufficient material (neither side can force checkmate), or mutual agreement.
Strategy notes
Opening Principles
The three core opening principles: control the center (e4, d4, e5, d5 are the most valuable squares), develop your pieces early (knights before bishops; get pieces to active squares before moving any piece twice), and castle early to tuck your king behind pawns. Avoid moving the queen early — it is easily chased, wasting tempo.
Pawn Structure
Pawns are the soul of chess. Doubled pawns (two pawns of the same color on the same file) are usually weak. Isolated pawns (no friendly pawns on adjacent files) need defense and cannot be protected by other pawns. Passed pawns (no opposing pawns blocking or capturing them) are strong endgame assets. Backward pawns and pawn islands (groups of disconnected pawns) count against your position.
Positional Play
Positional chess is about accumulating small advantages: outpost squares (squares no enemy pawn can contest), the two bishops (generally superior to bishop + knight or two knights in open positions), rook activity (open and half-open files), piece coordination, and king activity in the endgame. Prophylaxis — preventing your opponent's plan — is as important as executing your own.
