Portable Game Notation ("PGN") is a notation term: this is a popular computer-processible ASCII format for recording chess games (both the moves and related data). There are import and export versions: the import version is lax, while the export version is not. This matters because clear notation lets you replay, review, and share chess positions without confusion.
