To interrupt the computing time and force a computer move instantly. The computer will 
make the move it currently considers the best. Please allow at least 5 seconds of search time

 

before pressing this key in order to let the computer calculate a reasonable move. The 
evaluations of these moves do not correspond with the evaluation of the set-up level. 

To change sides during a game. In this case you have to lift the opponent’s King off the board 
briefly, e.g. if you play white, wait until it is your turn. Lift the black King off the board 
briefly. The computer will now compute a move for white, and you will play the black from 
now on. 

To let the computer play against itself, which might be of special interest at a certain point 
during the game or for learning purposes. Every time you activate GO the computer calculates 
for the side to move. All moves will be computed according to the set playing levels. For 
example if you are playing white: 
- Wait until it is your turn. 
- Lift the black King off the board briefly. The computer now plays white and you only 

have to make the move for the unit. 

- Now lift the white King off the board briefly. This will prompt the computer to calculate a 

move for black and you will only have to make the move for the computer. And so on…
