Courier chess
Courier chess (or The Courier Game or simply courier) is a strategy board game in the chess family. The original form probably originated in the 12th century and is known to have been played for at least six hundred years. The game was subsequently replaced by a more modern form. It pioneered the modern chess bishop (called the "courier"), and probably played a part in evolving modern chess out of Medieval Chess.
Courier Chess is played on a board of eight by twelve . Literary and artistic evidence indicate that the board was checkered from the beginning, but that there was no consistency as to which squares were dark. The more frequent practice seems to be that the square at each player's lower-right is white.
