Lesson plan
GBR code
The GBR code (or Guy–Blandford–Roycroft code) is a system of representing the position of chess pieces on a chessboard. Publications such as EG use it to classify endgame types and to index endgame studies. The code is named after Richard Guy, Hugh Blandford and John Roycroft. The first two devised the original system (the Guy–Blandford code) using different figures to represent the number of pieces. Roycroft suggested to count one for a white piece and three for a black piece in order to make the code easier to memorise.
