The gambits are organized into sections by the parent chess opening, giving the gambit name, ECO code, and defining moves in algebraic chess notation. Alekhine's Defense [ edit ]
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. [ 1 ] It is now almost universally used by books, magazines, newspapers and software, and is the only form of notation recognized by FIDE , [ 2 ] the ...
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.
For example, the move that would be written 1.e4 in algebraic notation would be written 1. 5254 in numeric notation: the pawn starts from square 52 (file 5, rank 2) and moves to square 54 (file 5, rank 4). Numeric notation does not explicitly mark the type of moving piece, captures, or checks; every move is written as four digits unless ...
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.
This includes move number indicators (numbers followed by either one or three periods; one if the next move is White's move, three if the next move is Black's move) and movetext in Standard Algebraic Notation (SAN). For most moves the SAN consists of the letter abbreviation for the piece, an x if there is a capture, and the two-character ...
The notation for any given move is almost always more concise in algebraic notation than in descriptive notation; this can reduce the length of chess books and magazines by several pages. While confusion can arise in descriptive notation because each square has two names, no such problem exists in algebraic notation.
This is a list of chess openings, organised by the Encyclopaedia of Chess Openings (ECO) code classification system.The chess openings are categorised into five broad areas ("A" through "E"), with each of those broken up into one hundred subcategories ("00" through "99").
