Open PGN File
A PGN file extension can take on a text-based file format used to record the moves of a game of chess.
The most suitable software to open and work with a PGN file is ChessBase Fritz, which is a German chess program originally developed for Chessbase by Frans Morsch, and later ported to DOS, and then Windows by Mathias Feist.
The PGN also includes the event name, location, date, round, player names, and match result.
The header information of a PGN file is formatted using tags, and after the header, the player's moves are described using 'movetext', a syntax based on Standard Algebraic Notation (SAN).
Chess notation, or Standard Algebraic Notation, comprises the systems that have been developed to record the moves made in a game of chess or the position of the pieces on a chessboard.
Early notational systems used lengthy narratives to describe each move, however these gradually evolved into more concise notational systems.
Currently, algebraic chess notation is the accepted standard and is widely used, especially for PGN files.
In any case, apart from ChessBase Fritz, various chess programs and PGN viewers can be used to view PGN files.
