'''Algebraic Chess Notation''' is a chess notation to record and represent [[Moves|moves]] of a [https://en.wikipedia.org/wiki/Human-readable_medium human readable] [[Game Notation|game notation]]. It is based on a system developed by [https://en.wikipedia.org/wiki/Philipp_Stamma Philipp Stamma] to notate the [[Target Square|target square]] by [[Squares#Algebraic|algebraic coordinates]], and various forms to represent the [[Origin Square|origin square]] of the move, either by language dependent [https://en.wikipedia.org/wiki/Algebraic_chess_notation#Naming_the_pieces_in_various_languages piece initials] and/or [[Files|file]], [[Ranks|rank-]] or [[Squares|square]] notation of the from- or origin square. [[Promotions]] must be disambiguated by including the promoted piece type, and [[Castling|castling]] usually has their own symbol strings ('O-O', 'O-O-O'). Some format variations also specify a [[Captures|captured]] piece, if any, for the purpose to make the notation reversible, and to go backward as easy as forward while re-playing a game.

The language independent [https://en.wikipedia.org/wiki/ICCF_numeric_notation ICCF numeric notation] as used in [https://en.wikipedia.org/wiki/Correspondence_chess Correspondence chess] is a numerical pure coordinate notation, giving coordinates by two digits (File '1'-'8) rather than letters ('a'-'h') for the file. In case of promotions a fifth trailing digit is used: '1' for queen, '2' for rook, '3' for bishop and '4' for knight.
