2. Turochamp - Wikipedia

   en.wikipedia.org/wiki/Turochamp

   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 ...

3. Algebraic notation (chess) - Wikipedia

   en.wikipedia.org/wiki/Algebraic_notation_(chess)

   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.

4. Endgame tablebase - Wikipedia

   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.

6. Chess notation - Wikipedia

   en.wikipedia.org/wiki/Chess_notation

   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.

7. Proof game - Wikipedia

   en.wikipedia.org/wiki/Proof_game

   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.
