Algebraic notation. 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]
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 ...
To accommodate Algebraic Notation in addition to PGN, it can accept 0-0 and 0-0-0 for castling (PGN standard mandates O-O and O-O-O, i.e., capital-letter O, not digit zero) viewer now fully supports Chess960 .

The notation for chess moves evolved slowly, as these examples show. The last is in algebraic chess notation; the others show the evolution of descriptive chess notation and use spelling and notation of the period. 1614: The white king commands his owne knight into the third house before his owne bishop. 1750: K. knight to His Bishop's 3d.
For notation purposes, the three board levels are denoted 1, 2 (the middle board), and 3. Moves are recorded in the same manner as chess, using algebraic notation, with the only difference that each square is prefaced by its level number. The white and black armies begin, in standard formation, on boards 1 and 3 respectively.
Board representation in computer chess is a data structure in a chess program representing the position on the chessboard and associated game state. [1] Board representation is fundamental to all aspects of a chess program including move generation, the evaluation function, and making and unmaking moves (i.e. search) as well as maintaining the state of the game during play.
Each square of the board is named using algebraic, descriptive, or numeric chess notation; algebraic notation is the FIDE standard. In algebraic notation, using White's perspective, files are labeled a through h from left to right, and ranks are labeled 1 through 8 from bottom to top; each square is identified by the file and rank which it ...
