Questions tagged [notation]

Notation refers to any formalized method of recording chess games so they can be replayed and shared later. Common notations include algebraic, figurine algebraic, descriptive, and the digital PGN format. Descriptive notation is considered obsolete, though familiarity with it allows one to read older books that use it.
