Retracting and replaying moves 

 

3.5.1    Retracting a move 

If you want to take back the last move played, you may press the clockwise arrow button       . The red lights 
on the chessboard, and the prompts in the bottom line of the screen, direct you to move the piece back, e.g.: 

 

Return the white bishop from h4 to g5, pressing the squares as you do so. (Alternatively press RED and 
simply move the piece 

 compare Section 3.2.) 

 

3.5.2    Retracting a sequence of moves  

After taking back one move, you may also take back the previous one or a longer sequence.  

To do this, you can repeat the same procedure as before. However, in a long sequence you don’t need to 
retract the moves one by one in a specific order. For example, to retract the last seven moves played, you can 
simply press       seven times and then proceed to reconstruct the position, pressing the squares that are 
indicated in the bottom line. The VERFY function (see Section 5.1.3), as well as the red lights on the board, 
can help you. 

 

3.5.3    Replaying moves 

A move that you have retracted can be 

replayed

 by pressing the 

anticlockwise

 arrow button       and moving 

the piece on the board as prompted by the lights and the screen.  

To replay a sequence, you may repeat this same procedure to execute each individual move. Alternatively, 
you may simply press the anticlockwise arrow button several times and then reconstruct the position at the 
end of the sequence.  

 

3.5.4    Continuing the game 

At any time after retracting or replaying moves, you can resume the game from the current position on the 
board. Carry out a move in the normal way, or give the ‘Move’ command (see Section 5.2) to make the 
computer play next 

 you will then be playing for the opposing colour. 

3.6

 

Result of the game 

The final move is accompanied by three ‘beeps’, and the result is announced in the bottom line of the 
display: 

 

Mate    

Checkmate 

 

Stale    

Stalemate 

 

Draw 3x  

Draw by threefold repetition 

 

Draw 50  

Draw by 50-move rule 

 

NoMat    

Draw due to insufficient material (neither side can mate the opponent) 

 

TooLong  

The game cannot be continued, as it would exceed the available    

 

 

 

memory space (maximum: 256 moves for each side). 

3.7

 

Starting a new game 

You can start a new game at any time, except in the middle of some special operations as described in 
Section 5. 

Press the NEW button. The screen shows ‘New Game?’ and 

either

 the word ‘Classic’ 

or

 an arrangement of 

pieces to start a game of ‘Chess 960’. To switch between these displays, use 

ñ

 or 

ò

.  

To begin a game of ordinary (‘classical’) chess, press GREEN when the screen shows ‘Classic’.
