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
Chess notation an almost fully developed form before the now obsolete descriptive chess notation evolved. The main difference between Stamma's system and the modern system is that Stamma used "p" for pawn moves and the original file of the piece ("a" through "h") instead of the initial letter of the piece. In London in 1747, Philidor convincingly defeated Stamma in a match. Consequently, his writings (which were translated into English) became more influential than Stamma's in the English-speaking chess world; this may have led to the adoption of a descriptive system for writing chess moves, rather than Stamma's coordinate-based approach. However, algebraic
