Chess: 31 Interesting Facts You Might Not Know

Chess is a strategic board game designed for two participants, known as White and Black, who each command their own set of chess pieces. The primary goal is to achieve checkmate against the adversary’s king. Occasionally referred to as international chess or Western chess, it is differentiated from similar games like xiangqi (Chinese chess) and shogi (Japanese chess).

The game is played on a 8×8 grid board.  Each player starts with 16 pieces, including a king, queen, bishops, knights, rooks, and pawns. The objective is to checkmate the opponent’s king, meaning the king is in a position to be captured with no legal moves to escape.

Pieces move in specific ways: pawns advance forward but capture diagonally, rooks move horizontally or vertically, knights have an L-shaped move, bishops diagonally, queens can move in any direction, and kings move one square in any direction.

Castling is a special move involving the king and rook to enhance the king’s safety. En passant allows a pawn to capture another pawn that has moved two squares forward. Pawn promotion occurs when a pawn reaches the eighth rank, and it can be replaced by any other piece. Players take turns making one move at a time, and the game concludes with a checkmate, stalemate, draw by agreement, or specific draw conditions.
