The ultimate goal of chess is to put the opponent's king in checkmate, which means the king is under attack and has no way to escape capture.

A chessboard consists of 64 squares arranged in an 8x8 grid, with alternating light and dark colors.

The six types of pieces in chess are the King, Queen, Rook, Bishop, Knight, and Pawn.

Pawns can move forward one square, or two squares if they are on their first move. They cannot move backward or sideways.

When a pawn reaches the eighth rank, it can be promoted to a Queen, Rook, Bishop, or Knight.

Castling is a special move where the King and a Rook move at the same time. The King moves two squares towards the Rook, and the Rook moves to the other side of the King.

Check is the term used when a player's King is under attack by an opponent's piece.

Checkmate is the term used when a player's King is under attack and has no way to escape capture.

Stalemate is the term used when a player has no legal moves to make and is not in check.

A draw can occur in several ways, such as when both players agree to a draw, when there is a stalemate, or when the same position is repeated three times.

Algebraic notation is the most common way to record chess moves. It uses letters and numbers to indicate the squares on the board.
