Portable Game Notation Algebraic Notation (SAN). For most moves the SAN consists of the letter abbreviation for the piece, an codice_27 if there is a capture, and the two-character algebraic name of the final square the piece moved to. The letter abbreviations are codice_28 (king), codice_29 (queen), codice_30 (rook), codice_31 (bishop), and codice_32 (knight). The pawn is given an empty abbreviation in SAN movetext, but in other contexts the abbreviation codice_33 is used. The algebraic name of any square is as per usual algebraic chess notation; from white's perspective, the leftmost square closest to white is codice_34, the rightmost square closest to the
Algebraic notation (chess) of chess is ICCF numeric notation. In recent years, the majority of correspondence games have been played on on-line servers rather than by email or post, leading to a decline in the use of ICCF numeric notation. Chess games are often stored in computer files using Portable Game Notation (PGN), which uses algebraic chess notation as well as additional markings to codify a game. As mentioned, PGN requires uppercase letter "O" to represent castling (e.g. O-O), while the FIDE Handbook uses digit zero (0-0). Though not technically a part of algebraic notation, the following are some common symbols frequently used
