Most attack tactics tend to work the same from either end of the board, and thus it is sometimes efficient to refer to a square from a generic perspective. (Thus is perhaps the main usefulness of descriptive notation in modern times. The square f2 is on the King's Bishop's file, and thus is KB2 for White, but of course KB7 for Black. For White it would be Q3 for Black we invert the perspective and thus from his perspective it is Q6. Thus, for example, the square that is familiar to players as d3 in algebraic notation, would be on the Queen file in descriptive. For White, they are the same as in algebraic notation, however, descriptive notation is perspective based, so for Black they are numbered beginning at Black's back row, in other words White's 8 is Black's 1 and vice versa, and similarly 2 and 7, 3 and 6, 4 and 5 are inverted for Black as compared to White.Ī square's full name, thus, is the combination of its file name (or abbreviation) and its rank number from the player's perspective.
The files the queen and king themselves start the game on are of course simply the Queen and King files with their single letter abbreviations. For instance, the file on which the queen's side rooks begin the game on is called the Queen's Rook's file, abbreviated QR the file that the king's side knights begin the game on would be the King's Knight's or KKt (alternatively KN) file. The eight files are named based on the lateral side (Queen's or King's) of the board they belong to and the name of the piece that starts the game on that file. The main exceptions are the knight and pawn the former is often referred to as Kt (although the modern N is also valid) and the latter, which nominally lacks an abbreviation in algebraic is explicitly referred to as P in descriptive. In descriptive notation, pieces are referred to mainly by the same letters as they are in the newer algebraic notation. In addition, it can sometimes be useful to reference squares in descriptive as noted below. As such, while it has been supplanted in modern use by algebraic notation a knowledge of descriptive notation remains important as a large wealth of classical chess literature uses it and much of it has not been republished in the newer format. Descriptive notation was the most common form of notation used to record a chess game until late in the 20th century.
