Description
AUTHOR- Dr. Alistair Ward
DESCRIPTION
- https://www.chessprogramming.org/Algebraic_Chess_Notation#Pure_coordinate_notation.
- CAVEAT: https://en.wikipedia.org/wiki/Chess_notation defined a variant of this notation.
- N.B.: used for communication via CECP with xboard.
- N.B.: this minimal notation defines the coordinate-system on which Standard Algebraic is based.
