A chessboard is the board on which the game of chess is played.

The board has a square shape with its side being divided into eight parts resulting in a total of sixty-four subdivisions whose colors alternate between two colors. Each subdivision of the board is called a square and receives a unique identification to be used in chess notation, which may be descriptive, algebraic, or numeric. Each horizontal array of squares is called a rank, each vertical array of squares is called a file, and each line of squares of the same color touching corner to corner is called a diagonal.
