Level 15 is a MATE level that is intended to resolve checkmate problems (see paragraph XI).
Level 0 is a MULTI MOVE level that allows two players to play each other while the computer is the referee and checks the legality of the moves.
The computer also has four different playing styles:
In NORMAL style, the computer has no specific preference for either the defensive or the attacking mode.
In AGGRESSIVE style, the computer plays an offensive game and tries to prevent the exchange of chess-men as much as possible.
In DEFENSIVE style, the computer makes a point of constructing a solid defence. It moves its pawns extensively and tries to exchange chess-me n
as often as possible.
In HIGH-RISK style, the computer moves its pawns extensively and sometimes chooses to play an unexpected move rather than always try to make
the best possible move.
When you switch on the computer for the first time, the game starts automatically at level 6 and in the NORMAL playing style. Afterwards it maintains
the level and playing style you were in when you switched off the computer or when you pressed the NEW GAME button.
To change the game level and style, follow these instructions:
1. Press the LEVEL button to enter the level selection mode.
(for example, square A6 corresponds to level 6, normal game style).
2. Refer to the table above to find the corresponding square for the desired game level and style. Press the square you need.
3. Press the LEVEL button again to leave the level selection mode. Then you can start playing and make your first move, or press on MOVE
to let the computer make the first move.
If you want to check which level and style are selected without changing anything, follow this procedure:
1. Press the LEVEL button.
2. Press the LEVEL button once again to return to the game.
You can modify or check the game level at any time during the game when it is your move.
XI. RESOLVING CHECKMATE PROBLEMS
Level 15 is the CHECKMATE level and this allows you to solve checkmate problems up to checkmate in 5 moves. To resolve checkmate problems:
1. Install the chess-men on the chessboard and record their positions (see paragraph XIX).
2. Select level 15 and press the LEVEL button, then squares B7, D7, F7 or H7, then press the LEVEL button once again.
3. Press the MOVE button. The computer commences its analysis.
The computer will think until it finds a checkmate situation and then play its first move towards checkmate. You may then respond and the computer
will in turn find the next move towards checkmate. If the position does not allow checkmate, the computer will analyse the situation indefinitely. The
approximate delay times for resolving checkmate problems are:
Mate in 1 move 1 second
Mate in 2 moves 1 minute
Mate in 3 moves 1 hour
Mate in 4 moves 1 day
Mate in 5 moves 1 month
