ply, and thus only looks ahead one individual move. This
results in much weaker play, giving beginners and aver-
age players a better chance of beating the computer.
These levels start out easy and get progressively more
difficult—as you conquer each level, go on to the next!

3.9 Quiet Closed Game Levels (F1-F8)

QUIET CLOSED GAME LEVELS

AVERAGE TIME PER MOVE

Square F1 ...................... 1 second
Square F2 ...................... 2 seconds
Square F3 ...................... 5 seconds
Square F4 .................... 10 seconds
Square F5 .................... 30 seconds
Square F6 ...................... 1 minute
Square F7 ...................... 2 minutes
Square F8 ...................... 3 minutes

On these eight levels, the computer gives preference

to a quiet, passive style of play. Here, you will see the
computer exchanging pieces as much as possible, in an
effort to avoid complications and simplify the board posi-
tion. With this type of play, the program also avoids at-
tacks and keeps positions closed whenever possible.

3.10 Aggressive Game Levels (G1-G8)

AGGRESSIVE GAME LEVELS

AVERAGE TIME PER MOVE

Square G1 ...................... 1 second

move or make a move of your own.

3.5 Mate Finder Level (B8)

MATE FINDER LEVEL

PURPOSE

Square B8 ......... Solves mate problems

Selecting this level activates a special mate finder

program. If you have a position where there may be a
mate and you want the computer to find it, set the com-
puter on this level. The computer will then search for a
forced mate, and will only play a move if it finds a mate. It
can solve mates in up to four moves.

If there is no mate present or if the computer cannot

find a mate, it sounds a beep and the previously flashing
color indicator turns on steadily. You may continue play, if
desired, by simply changing levels.

3.6 Practice Levels (C1-C8)

PRACTICE LEVELS

AVERAGE TIME PER MOVE

Square C1 ...................... 1 second
Square C2 ...................... 2 seconds
Square C3 ...................... 5 seconds
Square C4 .................... 10 seconds
Square C5 .................... 30 seconds
Square C6 ...................... 1 minute
Square C7 ...................... 2 minutes
Square C8 ...................... 3 minutes

The Practice Levels offer you a great chance to

sharpen your chess playing skills! On these levels, the
computer will play for captures and checks as much as
possible. The program may intentionally overlook traps in
order to encourage you to play for traps and threats. You
will also notice the computer positioning its pieces so that
they may easily be attacked.

3.7 Tactical Levels (D1-D8)

TACTICAL LEVELS

AVERAGE TIME PER MOVE

Square D1 ...................... 1 second
Square D2 ...................... 2 seconds
Square D3 ...................... 5 seconds
Square D4 .................... 10 seconds
Square D5 .................... 30 seconds
Square D6 ...................... 1 minute
Square D7 ...................... 2 minutes
Square D8 ...................... 3 minutes

Although the Tactical Levels have the same search

times as the Normal Playing Levels, the computer plays
differently here because it employs a different search
method. On the Normal Playing Levels, the computer
uses a Selective Search algorithm. This method allows
the computer to see combinations that would otherwise
take much longer to compute. On the Tactical Levels,
however, the computer switches to a powerful Brute
Force Search algorithm. This helps to minimize the risk of
an occasional oversight.

3.8 Fixed Depth Levels (E1-E8)

FIXED DEPTH LEVELS

SEARCH DEPTH

Square E1 .......................... 1 ply
Square E2 .......................... 2 ply
Square E3 .......................... 3 ply
Square E4 .......................... 4 ply
Square E5 .......................... 5 ply
Square E6 .......................... 6 ply
Square E7 .......................... 7 ply
Square E8 .......................... 8 ply

On the Fixed Depth Levels, the computer’s search

depth is limited to certain number of 

ply.

 A ply is an indi-

vidual move, or a move for either side. As an example, on
Level E1, the computer only searches to a depth of one
