Algebraic notation (chess)
Summary
Algebraic notation is the standard method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the board. It is used by most books, magazines, and newspapers.
An early form of algebraic notation was invented by the Syrian player Philip Stamma in the 18th century. In the 19th century, it came into general use in German chess literature, and was subsequently adopted in Russian chess literature. In English-speaking countries, the parallel method of descriptive notation was generally used in chess publications until the 1980s. A few players still use descriptive notation, but it is no longer recognized by FIDE, the international chess governing body.
The term "algebraic notation" may be considered a misnomer, as the system is unrelated to algebra.
Each square of the board is identified by a unique coordinate pair—a letter and a number—from White's point of view. The vertical columns of squares, called , are labeled a through h from White's left (the ) to right (the ). The horizontal rows of squares, called , are numbered 1 to 8 starting from White's side of the board. Thus each square has a unique identification of file letter followed by rank number. For example, the initial square of White's king is designated as "e1".
Each piece type (other than pawns) is identified by an uppercase letter. English-speaking players use the letters K for king, Q for queen, R for rook, B for bishop, and N for knight. Different initial letters are used by other languages.
In chess literature, especially that intended for an international audience, the language-specific letters are often replaced by universally recognized piece symbols; for example, ♞c6 in place of Nc6. This style is known as figurine algebraic notation. The Unicode Miscellaneous Symbols set includes all the symbols necessary for figurine algebraic notation.
In standard (or short form) algebraic notation, each move of a piece is indicated by the piece's uppercase letter, plus the coordinate of the destination square.
