The notation for chess moves evolved slowly, as these examples show. The last is in algebraic chess notation; the others show the evolution of descriptive chess notation and use spelling and notation of the period. 1614: The white king commands his owne knight into the third house before his owne bishop. 1750: K. knight to His Bishop's 3d.
When a piece makes a capture, an "x" is inserted immediately before the destination square. For example, Bxe5 (bishop captures the piece on e5). When a pawn makes a capture, the file from which the pawn departed is used to identify the pawn. For example, exd5 (pawn on the e-file captures the piece on d5).
The players, referred to as "White" and "Black", each control sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns. White moves first, followed by Black; then moves alternate. The object of the game is to checkmate (threaten with inescapable capture) the enemy king
Portable Game Notation (PGN) is a standard plain text format for recording chess games (both the moves and related data), which can be read by humans and is also supported by most chess software. This article uses algebraic notation to describe chess moves.
In algebraic notation, an en passant capture is notated using the capturing pawn's destination square. In both algebraic and descriptive notation, the move may optionally be denoted by appending "e.p." or similar. For example, in algebraic notation, bxa3 or bxa3 e.p. may be used to represent a black pawn on b4 capturing a white pawn on a4 en ...
The example here is a study by Henri Rinck first published in La Stratégie in 1920. It is White to play and win. Normally, Black would be able to sacrifice his rook for the white bishop, leaving a drawn position (sacrificing it for a knight would be no good, since it is possible to force mate with bishop and knight), but in this case it turns out that the rook is dominated, and its capture ...
There are other symbols used by various chess engines and publications, such as Chess Informant and Encyclopaedia of Chess Openings, when annotating moves or describing positions. [8] Many of the symbols now have Unicode encodings, but quite a few still require a special chess font with appropriated characters.
X-FEN (formerly FRC-FEN) is an extension of Forsyth–Edwards Notation (FEN) introduced by Reinhard Scharnagl in 2003. [1] It was designed to be able to represent all possible positions in Fischer random chess (FRC) and Capablanca random chess (CRC). It is fully backward compatible with FEN.
