Chess notation is a formal written system used to record moves in chess games. Each piece is represented by a letter, and positions on the board are represented by a letter and number combination.
Each piece is represented by the first letter in its name, with the exception of the knight (represented by "N") and the pawn (not given a letter). The numbers 1-8 represent the vertical squares on the grid, and the letters A-H represent the horizontal squares. Captures are indicated with an "x", and moves that put a king in check are represented with a "+". Castling to kingside is "0-0", and castling to queenside is "0-0-0".
