Game Notation refers to the recording of moves of the chess game including players or programs names, date, name of event and site - in human competitive chess each side is required to fill and sign a score sheet. In official computer chess over the board tournaments, it was required for human operators as well, but was practically relaxed since programs keep their internal move list persistent and were able to restart for instance after a power failure [1]. In Chess GUIs, the game notation is presented inside a notation window, which may allow certain interactions, like scrolling the list, or replaying the game.
Chess Notation
While the move numeration is quite obvious, starting with move number one, there are various Chess notations with different move syntax defined. Most common in printed and electronic chess media, also in chess programs and databases, is the Algebraic Chess Notation, especially its short form called SAN. Descriptive chess notation was used in English and Spanish-language literature until the late 20th century, but is today somehow obsolete.

In an attempt of Computer vision, Henry S. Baird and Ken Thompson used optical character recognition along with various heuristics and applying the rules of chess, to "read" the games of Informant's Encyclopaedia of Chess Openings with high accuracy and a success rate of 99.995% on approximately one million characters (2850 games, 945 pages) [2]. FAN is supported by various chess GUIs, corresponding chess symbols are available in Unicode [3] [4].
