Grid chess is a chess variant invented by Walter Stead in 1953. [1] It is played on a grid board. This is a normal 64-square chessboard with a grid of lines further dividing it into larger squares. A single additional rule governs Grid chess: for a move to be legal, the piece moved must cross at least one grid line. Grid chess is also used in ...
Algebraic notation. 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]
In contemporary chess, a digital board is a chess board connected to a computer that is capable of transmitting the moves to the computer itself: the information about the moves can be used to play a game against a chess engine, or simply to record the moves sequence of a game in automatic.
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.
Grid chess: The board is overlaid with a grid of lines. For a move to be legal, it must cross at least one of these lines. Guard chess (or Icelandic chess): Allows captures only when a piece is completely unprotected by friendly pieces. Checkmate occurs when the piece forcing the mate is protected and therefore cannot be captured.
Grid chess – 8×8 board with a 4×4 grid, dividing the board in 16 spaces of 2×2 squares each. Works just like traditional chess, except that a piece must cross at least one grid line at each move. Cylinder chess – played on a cylinder, which results in joining the right and left sides of the board.
The 27×27 board is the highest-order board that has been completely enumerated. [5] The following tables give the number of solutions to the n queens problem, both fundamental (sequence A002562 in the OEIS ) and all (sequence A000170 in the OEIS ), for all known cases.
The 0x88 chess board representation is a square-centric method of representing the chess board in computer chess programs. The number 0x88 is a hexadecimal integer (136 10 , 210 8 , 10001000 2 ). The rank and file positions are each represented by a nibble (hexadecimal digit), and the bit gaps simplify a number of computations to bitwise ...
