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.
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
again.
3. Press
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:
