The computer has 13 different levels of difficulty plus 3 special levels:
• Level 1 to 5 are beginner levels; the computer will make mistakes to let the player take
some pieces.
On level 1 the computer will make lots of mistakes, and even sometimes place a piece on a
square where it can be immediately captured by a pawn. Playing on this level is a good way to
learn how the pieces move. You can also switch to level 1 if you are losing a game and want the
computer to make a few mistakes.
On level 2 the computer will also make lots of mistakes, but it will never place a piece on a
square where it can be immediately captured by a pawn.
On level 3 the computer will make a couple of mistakes per game.
On level 4 the computer will on average make only one mistake per game, and it will place the
queen on a square where it can be immediately captured.
On level 5 the computer will overlook certain forks and mate threats, but it will never place
pieces on squares where they can be immediately captured.
The computer moves almost instantly on all these levels.
• Level 6 up to 13 give a range of time settings from 5 seconds to 2 hours per move. The
playing strength on these levels ranges from beginner to expert. Level 6 is for blitz chess
(5 seconds per move), level 8 is for fast chess (30 seconds per move), and level 10 is for
tournament chess (3 minutes per move). The times are approximate average response
times. The computer will spend more time in complicated positions and less time in simple
positions and in the endgame. The computer thinks in your time too, so sometimes it will
be able to move instantly, because you made the move it had anticipated! The program
also moves instantly when it plays a move from the opening library.
• Level 14 is a special analysis level that will analyse the position for around 24 hours or
until you terminate the search by pressing the MOVE key (see TERMINATING SEARCH later).
• Level 15 is a special CHECKMATE level for solving mate problems (see MATE PROBLEMS
later).

• Level 0 is a special MULTI MOVE mode that allows two persons to play against each
other, while the computer checks that the moves are legal (see MULTI MOVE later).
The computer also has 4 different playing styles:
• In NORMAL mode the computer will equally on attack and defend.
• In AGGRESSIVE mode the computer plays the game on the offensive and avoids
surrendering pieces as much as possible.
• In DEFENSIVE mode the computer's priority is to construct a solid defence. It moves its
pawns a lot and will exchange pieces as often as possible.
• In RANDOM mode the computer moves its pawns a lot and sometimes prefers to make
an unexpected move rather than always to make the best move.
When you switch the computer on for the first time, the game will automatically start on level 6
and in NORMAL mode. After that, it saves the level and game mode when you switch it off and
when you press .
To change the level or the playing style:
1. Press the key to enter the level setting mode. The computer lights up the key
corresponding to the current level and playing style (for example, key A6: A for NORMAL,
6 for level 6).
2. Check in the table above to find the square corresponding to the level and playing style
you want to select. Press that square on the board.
3. Press the key again to return to the game.
To check the level number or playing style WITHOUT changing the level:
1. Press the key to enter the level setting mode. The computer will show the current
level by lighting up the square (A6 for level 6 and NORMAL playing style).
2. Press the key again to exit from the level setting mode.
You can change or check the level and playing style at any time during the game, when it is
your turn to move.
XII. RESOLVING CHECKMATE PROBLEMS
Level 15 is a special CHECKMATE level for solving checkmate problems in up to 5 moves. To
solve a mate problem:
1. Set up the position on the board (see SET-UP POSITION later).
2. Select level 15 by pressing then the squares B7, D7, F7 or H7 and then
again.
3. Press . The computer will then begin its analysis.
The computer will think until it finds a way to achieve checkmate, then it will make the first
move towards the checkmate. You can then act as opponent and the computer will find the
next move towards checkmate. If checkmate is not possible, the computer will analyse
indefinitely. The approximate delays for resolving a checkmate problem are as follows:
Checkma te in 1 move 1 second
Checkma te in 2 move s 1 minute
Checkma te in 3 move s 1 hou r
Checkma te in 4 move s 1 day
Checkma te in 5 move s 1 mon th
XIII. MULTI MOVE
Level 0 is a special MULTI MOVE mode. In this mode the computer does not play, so you may
enter the moves for both players. You can use this feature to enter a particular opening, or to
