It will come as a surprise to many that before the age of chess computers and the microcomputer program, the game of chess was originally played by two human beings.

An intelligent chess playing program would take up an entire book on it's own, so it was decided to develop a program which would be of genuine use to anyone who enjoyed playing chess or would like to learn more about it. Chess clubs could also find the program helpful.

The program can be used simply as a replacement for a chess board and pieces. The two players enter their moves in usual standard chess notation. However, extra features have been included to produce worthwhile advantages over the traditional board and pieces.

The computer will examine all entries for legality of the move. Only moves which arc the correct colour, arc from occupied squares and move to a square which can be reached by that piece, will be accepted. Pieces which are ‘taken' in the process are removed from the board.

The program does not indicate ‘check' or ‘mate' and will allow moves which reveal check. It is up to the humans to watch out for these. En passant is not automatically dealt with but the ‘remove' option may be used by a player to take the pawn if required on his move.

Castling is handled by the program. The present position of the king and rook have to be correct, with no pieces between them, for castling to be implemented. The routine will still castle if a piece has previously been moved but returned to the correct square. Moving through check is not monitored. These latter conditions must be detected by the players.

A useful feature is that the initial board may be set up for chess problems or chess variants and games of up to 100 moves can be stored and analysed step by step. Play can continue from any stage of a saved game or the present game can be re-started and then played from any subsequent move. Pawns are automatically promoted to a queen when they reach the appropriate rank.

Summary of commands and options

  1. Set up board. Enter ‘Y' when asked. Then sequentially from the top left, place each piece using a single letter. Move on using ‘Space'. White pieces: P=pawn, R=rook, N=knight, K=king,Q=queen, B=bishop. Black pieces: the same but with ‘Shift' held. White always plays up the board.
  2. Remove piece. ‘Shift' ‘R' then enter the position. Play continues with the next player.
  3. Castle. ‘Shift' ‘C then direction ‘1' or ‘R'.
  4. Save game. ‘Shift' ‘S'. You must ensure cassette Record and Play are on before saving as prompts are not displayed.
  5. Load Game. ‘Shift' ‘L\ then press ‘Play'. This loads the first file fou nd.
  6. Step through game. ‘Shift' ‘3' initiates step mode.‘Space'steps through each move. ‘Shift' ‘3' then ends mode.
  7. Quit. ‘Shift' ‘Q' resets for new game.

L'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent  du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko.
