An exclamation point "!" indicates a good move, [2] especially one that is surprising or requires particular skill. The symbol may also be interpreted as "best move". Annotators are usually somewhat conservative with the use of this symbol; it is not usually awarded to obvious moves that capture material or deliver checkmate.
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 ...
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 ...
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 ...
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.
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.
The Lasker Trap is a chess opening trap in the Albin Countergambit. It is named after Emanuel Lasker , although it was first noted by Serafino Dubois . [ 1 ] [ a ] It is unusual in that it features an underpromotion as early as the seventh move.
