Reversible Algebraic Notation
Reversible Algebraic Notation is a computer-friendly form of algebraic chess notation. It requires the piece being captured to be specified, making it possible for a computer to “reverse” a move easily. If a capture does not specify a piece, it is assumed to be a pawn capture. This form of notation is not really used by humans, who usually use: Algebraic Chess Notation (the non-reversible type).
