Chess diagrams are widely used in chess publications as an aid to visualisation, or to aid the readers to verify that they are looking at the correct position on their chessboard or computer. The symbols used generally resemble the pieces of the standard Staunton chess set , although a number of different fonts have been used over the centuries.
In chess, the endgame tablebase, or simply tablebase, is a computerised database containing precalculated evaluations of endgame positions. Tablebases are used to analyse finished games, as well as by chess engines to evaluate positions during play.
Claude Shannon. The Shannon number, named after the American mathematician Claude Shannon, is a conservative lower bound of the game-tree complexity of chess of 10 120, based on an average of about 10 3 possibilities for a pair of moves consisting of a move for White followed by a move for Black, and a typical game lasting about 40 such pairs of moves.
In the GBR code, every chess position is represented by six digits, in the following format: abcd.ef. a = queens; b = rooks; c = bishops; d = knights; e = white pawns; f = black pawns; For the first four digits, each of the first two white pieces counts as 1, and each of the first two black pieces counts as 3.
Chess notation systems are used to record either the moves made or the position of the pieces in a game of chess. Chess notation is used in chess literature, and by players keeping a record of an ongoing game. The earliest systems of notation used lengthy narratives to describe each move; these gradually evolved into more compact notation systems.
A chess opening theory table or ECO table (Encyclopaedia of Chess Openings) presents lines of moves, typically (but not always) from the starting position. Notated chess moves are presented in the table from left to right. Variations on a given line are given horizontally below the parent line.
These templates shows a chess diagram, a graphic representation of a position in a chess game, using standardised symbols resembling the pieces of the standard Staunton chess set. The default template for a standard chess board is {{ Chess diagram }} .
The Lucena position is a position in chess endgame theory where one side has a rook and a pawn and the defender has a rook. Karsten Müller said that it may be the most important position in endgame theory. [1] It is fundamental in the rook and pawn versus rook endgame. If the side with the pawn can reach this type of position, they can ...
