Chess
Chess is played on a square board divided into eight rows of squares called ranks and eight columns called files, with a dark square in each player's lower left corner. There are 64 squares on a chess board. The colors of the squares are laid out in a checker (chequer) pattern with light and dark squares. To make speaking and writing about chess easy, each square has a name. Rank are numbered from 1 to 8, and each file is lettered from a to h. The letter assigned to a file comes before the number.
