The computer will make its response to your weak move. When it has finished press 
the TAKE BACK key once to take back the computer move. This last move will be 
shown on the display in reverse, i.e. first the 

"to"

 square and then the 

"from"

 

square. Execute this move like any other ordinary one, i.e. applying pressure on 
both squares as indicated. 
 
Press TAKE BACK a second time to take back your weak move the same way as 
described above. 
 
Every time you press TAKE BACK the computer will reverse the last move which 
is shown on the LCD display. (It will flash on display until you take back this last 
move). 
 
The computer will also display any captured pieces - don't forget to update your 
board position accordingly! 
 
You may now resume your game by entering a new and hopefully stronger move or 
ask for the computer's next move by pressing the ENTER key. 
 
Use the VERIFY facility (see section 13) to verify the position in doubt. 
 
Please note that if you use CHANGE SIDE or SET UP function during the game, all 
the prior moves will be deleted and you cannot TAKE BACK moves made before 
the change of colour or position. 
 

Note:

   

You may take back the last 32 halfmoves, this enables you to rectify an 

 

earlier mistake or to play a different strategy. 

 

12.  CHANGING SIDES (Color Key) 

The computer is generally set to play Black and you White.    If you want to play 
Black in a new game, set up the Black pieces on rank 1 and 2 and the White ones on 
rank 7 and 8, in that case disregard the notations along the chess board. 
 
Now press:    NEW    GAME    Key    –    COLOR    KEY    –    ENTER    Key 
 
The computer will make its opening move for White from the top of the board, 
while you have your Black pieces in front of you.
