- After loading, the chessboard with pieces laid out for the beginning
- of a game will automatically appear. The program will ask the user
- whether he wants to play or set up the board differently. Press P to
- play. The user will be asked what colour he would like to play. Press
- W for white and B for black .Finally the level of play is requested.
- Press a number from 0 to 9. Usually it is sufficient to play at one of
- the lower levels (0 to 3, say) for a rapid response to moves.
- The position of the pieces on the board are defined by using the
- modern algebraic notation. The columns on the board are labelled A to
- H and the rows are 1 to 8. White Queens rook is always the square A1
- in the initial set-up. The rows and columns on the board are labelled
- on the screen.
- To enter your move, type the coordinates (column letter followed by
- row number) of the square of the piece you want to move followed by
- the coordinates of the square to which to which you wish to move to
- it. No delimiter between the coordinates "from" and "to" is required -
- it will be automatically be inserted. After you have typed in your
- move, the appropriate piece will be moved, and the computer will
- consider and apply its move.
- All legal moves are allowed including castling and en passant.
- Castling is achieved by entering the king's move. On entering your
- move, if you make an error, you may always correct it by using the
- shift key shifted or unshifted.
- A number of commands may be applied at any stage. Typing the key R
- asks the computer to recommend a move to you and will do so at the
- same level of search on which it is currently set. L allows you to
- change the level at which the computer is playing. Z will copy the
- entire screen to an attached printer. T will save the current game to
- cassette to enable it to be resumed later. X exits from the game to
- start afresh or to set up the board.
-
- SETTING UP THE BOARD
- You may set up the board to examine a problem as you wish. At the
- start of the game or after exiting, press S for set-up. The cursor
- keys 5, 6, 7 and 8 can be used either shifted or unshifted to move a
- flashing cursor around the screen. The command C clears the board of
- pieces completely. The delete key deletes the piece at the current
- cursor position. The letters K, Q, R, B, N and P are used to place the
- appropriate piece on the board. X exits from the set-up routine.
