In the FIDE rules for rapid chess, if a player leaves or places their king in check or commits any other illegal move, their opponent can claim a win. [ 8 ] In algebraic chess notation , a "+" is normally written after a checking move.
Staunton style chess pieces. Left to right: king, rook, queen, pawn, knight, bishop. The rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player abstract strategy board game. Each player controls sixteen pieces of six types on a chessboard. Each type of piece moves in a distinct way.
English draughts (British English) or checkers (American English), also called straight checkers or simply draughts, [note 1] is a form of the strategy board game checkers (or draughts). It is played on an 8×8 checkerboard with 12 pieces per side.
The bishop moves and takes exactly as in normal chess. Capturing is not mandatory. The camel (Golomb called it the cook) has a kind of extended knight's move: it goes one diagonal and two straight. With this move, it can jump over other pieces (like a knight jumps), but the camel takes by moving to the square on which the enemy piece is located.
A cross-check occurs from time to time in games. It is an essential tactic in winning endgames such as two queens versus one queen, or queen and pawn versus queen, where it is used to stop a series of checks from the opponent and force the exchange of queens. It is also used in some chess problems.
A variant first described by Claude Shannon provides an argument about the game-theoretic value of chess: he proposes allowing the move of “pass”. In this variant, it is provable with a strategy stealing argument that the first player has at least a draw thus: if the first player has a winning move in the initial position, let him play it, else pass.
Today's Game of the Day is good ol' Checkers. You know the rules: you can only move diagonally and you can't move backwards. If you're in position to jump over an opponent's piece, you have to do it.
The program's algorithms include an opening book which is a library of opening moves from games played by checkers grandmasters; a deep search algorithm; a good move evaluation function; and an end-game database for all positions with eight pieces or fewer.
