Algebraic notation is the standard method of chess notation, used for recording and describing moves. 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 ...
DTZ is the only metric which supports the fifty-move rule as it determines the distance to a "zeroing-move" (i.e. a move which resets the move count to zero under the fifty-move rule). [35] By definition, all "won" positions will always have DTZ ≤ {\displaystyle \leq } DTC ≤ {\displaystyle \leq } DTM.
Turochamp simulates a game of chess against the player by accepting the player's moves as input and outputting its move in response. The program's algorithm uses a heuristic to determine the best move to make, calculating all potential moves that it can make, then all of the potential player responses that could be made in turn, as well as further "considerable" moves, such as captures of ...
An alternative rule-set may also be specified (such as circe chess or losing chess), or a fairy piece may be substituted for an orthodox piece. An SPG-type problem is to find the shortest game in which White's and Black's corresponding moves are mirror images of each other. Possible solutions are 1. d4 d5 2. Qd3 Qd6 3. Qh3 Qh6 4. Qxc8#, 1. d4 d5 2.
The en passant capture is the only capturing move in chess where the capturing piece moves to a square not occupied by the captured piece. [6]: 463 Because many casual players are unfamiliar with or misunderstand the en passant rule, administrators on internet chess sites frequently receive erroneous complaints of bugs, cheating or hacking. [7]
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.
This article covers computer software designed to solve, or assist people in creating or solving, chess problems – puzzles in which pieces are laid out as in a game of chess, and may at times be based upon real games of chess that have been played and recorded, but whose aim is to challenge the problemist to find a solution to the posed situation, within the rules of chess, rather than to ...
A position where white wins with optimal play, regardless of who has the next move 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.
