Chess is played on a square board of eight rows (called ranks and denoted with numbers 1 to 8) and eight columns (called files and denoted with letters a to h). The colors of the 64 squares alternate and are referred to as “light” and “dark” squares. The chesoard is placed with a light square at the right-hand end of the rank nearest to each player. By convention, the game pieces are divided into white and black sets, and the players are referred to as “White” and “Black” respectively. Each player begins the game with 16 pieces of the specified color, which consist of one king, one queen, two rooks, two bishops, two knights, and eight pawns. The pieces are set out as shown in the diagram and photo, with each queen on a square of its own color, the white queen on a light square and the black queen on a dark.
