even let the computer play the whole game by itself!
To play an entire game with the black pieces from the top of the board:
1. Press the NEW GAME key, and set up the pieces with the black pieces at the top of the
board and the white pieces at the bottom of the board. Remember to place the white
queen on a white square and the black queen on a black square.
2. Then press the PLAY key. Pressing the PLAY key in the opening position turns the
board around. The computer will make a move for white from the top of the board, and
expect you to play the black pieces from the bottom of the board.
XIV. TAKING BACK MOVES
If you press down on one of your pieces, but then decide not to move it after all, just press
down on the square a second time. The computer will no longer show the square of the
piece, and you can make a different move by pressing the FROM and TO squares.
If you have already completed a move, and the computer is thinking about its reply, or has
already computed its reply and is showing the FROM square of the reply, then do the fol-
lowing:
1. Press the TAKE BACK key.
2. The computer stops thinking and instead shows the square of the piece you moved.
Press down on the square and pick up the piece.
3. The computer will then show the square that the piece came from. Press on this square
and move the piece back.
4. If the move was a capture or an en passant capture, the computer will remind you to
replace the captured piece by showing the square that the piece came from. Press down
on the square and replace the piece on the board.
5. If you take back a castle, you must first take back the king move and then the rook move,
pressing the squares for both the king and the rook.
If you want to take back your move after you have already made the computer’s move on
the board, you must first press the TAKE BACK key and take back the computer’s move in
the same way as described above, and then press the TAKE BACK key once more, and take
back your own move. If you have already pressed the FROM square of the computer’s reply
and the computer is showing the TO square, you must first carry out the computer’s move
in the normal manner, then press the TAKE BACK key and take back the computer’s move,
and finally press the TAKE BACK key again and take back your own move.
If you want to take back more than one move, press the TAKE BACK key once more, and
1. Set up the position on the board (see SET-UP POSITION later).
2. Select level 15 by pressing the LEVEL key and B7, D7, F7, or H7, and the LEVEL key
again.
3. Press the PLAY key, and the computer will start analyzing.
The computer will think until it has found a mate, and then it will play the first move in the
mate sequence. You may then make a move for the opponent, and the computer will find
the next move in the mate sequence and so on. If there is no mate in the position the com-
puter will analyze indefinitely. The approximate times for solving a mate problem are:
XII. MULTI MOVE
Level 0 is a special MULTI MOVE mode. In this mode the computer will not move itself, so
you may enter the moves for both players. You can use this feature to enter a particular
opening, or to replay a game to a certain position. You can also use the computer as a nor-
mal chess board, playing against another person while the computer checks that all the
moves are legal.
To enter the MULTI MOVE mode:
1. Select level 0 by pressing the LEVEL key and B8, D8, F8, or H8, and the LEVEL key
again.
2. Play as many moves as you want, pressing the FROM and TO squares for both players.
3. When you are done, exit the MULTI MOVE mode again by pressing the LEVEL key and
selecting another level.
XIII. CHANGING SIDES AND TURNING THE BOARD
If you press the PLAY key, the computer will make a move. Thus if you want to change sides
with the computer, just press the PLAY key. The computer will make a move, and expect
you to move for the other side.
If you press the PLAY key again, the computer will move again, and in this way you can
