Chess

RULES

Objective: Checkmate the opponent’s king (threaten the king with capture and there is no legal move to escape
Who goes first: White moves first; players then alternate one move at a time.
Turns & legality: On your turn, move one piece to a legal square. You may not make a move that leaves your own king in check.
Capturing: Most pieces capture by moving onto a square occupied by an enemy piece, removing it. Two pieces cannot share a square.
Check: If your king is attacked, you are in check. You must end your turn out of check by moving the king, blocking the attack, or capturing the attacking piece.
Checkmate: If your king is in check and you have no legal move to escape, that is checkmate—you lose.
Stalemate (draw): If it’s your turn and you have no legal move but you are not in check, the game is a draw.
Draws (other ways): Besides stalemate, the game is a draw by agreement, by threefold repetition (same position with same side to move and same rights occurs three times), by the 50-move rule (50 consecutive moves by each side with no pawn move and no capture), or by insufficient mating material (e.g., bare kings, king + bishop vs king, king + knight vs king).
