1. USING YOUR CHESS COMPUTER
First, Install the Batteries
1Your chess computer runs on four “AA” (AM3/R6)
batteries. For longer battery life, be sure to use fresh
alkaline batteries. Slide the GO/STOP switch to GO.
Insert the batteries as shown in Figure 1-1. The computer
will go through a self-test, then a
greet you, signalling that the computer is ready to play! If
the unit does not respond, use a paper clip or another
sharp object to press into the hole marked ACL in the
base of the unit for at least one second. This will reset the
computer.
If you would rather not power your unit with batteries,
you may purchase an optional AC adapter. Please use
only the adapter specified for use with this computer.
Important: To ensure that the computer’s memory contents are not lost, keep good batteries installed in the unit
even when you are using the optional AC adapter.

square you want to move to (see Figure 1-3). You will
hear a beep, and the computer will then start thinking
about its move.

moves which are stored in its openings library (for details,
see Section 2.12).

where the piece should go. Move the piece to the indicated square and press the piece down, as shown in
Figure 1-4. Once you have pressed this square, you have
completed the computer’s move! For an example of how
the board lights would indicate a computer move from e7
to e5, see Figures 1-5a and b.

4If you make a mistake or change your mind about a
move, it’s easy to take moves back! Press TAKE BACK
when it is your turn to move, and the computer will announce the move to be taken back (e.g.,
back Knight move
to guide you through the take-back. The to square of the
last move will light first—press the indicated piece down
on that square. The computer then shows you where that
piece came from. Press the piece down on the from
square to complete the take-back. Repeat the above
procedure to take back more moves, if desired. You may
take back up to six individual moves.
When taking back captures or castling maneuvers, the
computer will remind you of pieces which should be put
back on the board! It does so by lighting board lights to
indicate the position, and announcing the color and type
of the captured piece.

5Whenever you finish a game (or if you decide to abort
your current game), you may press NEW GAME to reset
the computer. The computer is then ready for another
game, using the currently selected level.
Caution: Since pressing NEW GAME clears your
current game from the computer’s memory, be careful not
to press this key by mistake!
Too Easy/Hard? Change Levels!
6When the computer is first turned on, it is set to Level
H4 (10 seconds a move). However, you may choose any
of the 64 playing levels described in Section 3!
Press LEVEL to enter Level Mode, and the board
lights will indicate the current level. To change playing
levels, press a board square to activate your desired
level, using the chart in Section 3 as a guide. Press
LEVEL again to exit level mode.
Voice, Beeps On/Off? It’s Your Choice!
7Your computer’s informative and entertaining voice
output is on by default, and you may use the Volume
Control Slider to set the desired volume. However, if you
would rather not have the voice on for some reason, you
have other options! As you will see in Section 4.2, you
can choose to hear only beeps, or you can even turn the
sound off for completely silent operation, if desired.
By the way, if you don’t hear what the computer says,
simply press the SAY AGAIN key on your turn to hear the
last message repeated.
Note that a) Pressing SAY AGAIN in Verify Mode or
when the computer is displaying Hint on your turn, the
computer will return to normal mode. b) SAY AGAIN is
disabled if voice/coach is set to level G or H, or if it is in
Level Mode.
2. ADDITIONAL COMPUTER FEATURES
2.1 Indication of the Side to Move
When Black is thinking about its move, board light 8
flashes. After it has moved, the 1 light comes on steadily
to show that it is now White’s turn to move. Similarly if
the computer plays White, the 1 light flashes during its
turn, and the 8 light comes on steadily after it has moved.
It’s easy to tell whether the computer is thinking and
whose turn it is!
2.2 Captures and Special Moves
During the game, the computer’s voice will normally
alert you to capture or to make special moves, such as

2.5 Getting Hints from the Computer
Whenever you need help, press SMART HINT on your
turn, and the computer will give you a move suggestion! If

assistance!
To accept the hint as your move, simply make the
suggested move on the board. If you would rather make a
different move, disregard the hint and press another piece
to make a move of your own.
2.6 Interrupting the Computer’s Search
To interrupt the computer while it is thinking, press
PLAY, and the computer will play the best move it has
found so far. This feature can be very useful on the higher
levels, where the computer can take a long time to move,
and on the Infinite Level, where the computer keeps
thinking indefinitely unless you stop it!
On the Mate Finder Level or Combination Level pressing PLAY does not cause the computer to make a move.
Instead, the computer sounds a double beep to indicate it
was interrupted before it found a mate or solution. To
continue your game, switch to another playing level.
2.7 Changing Sides with the Computer
To change sides with the computer, press PLAY when
it is your turn to move. The computer will make the next
move for your side. Change sides as often as you wish!
To see the computer play chess against itself, simply
press PLAY after each move—watch as it plays for both
sides of the board, one move after another. Study its
strategies—you might improve your own game!
2.8 Game Information
In a normal game of chess, you would never ask your
opponent what move he was thinking about, nor would
you question him as to how he would evaluate the current
position. When playing against this chess computer,
however, you can do just that! Upon request, it will show
you the move it is considering and evaluate the position
for you. Studying this information can help you to learn
more about chess!
Position Evaluation: You may get the computer’s

8. In a balanced position, for example, board lights 4 or 5
may be on. If the side playing from the bottom improves
its position, board lights 6, 7, or 8 may come on. Light 8
represents a great material advantage for the side playing
from the bottom—most probably a won position! When
the computer thinks the side playing from the top has a
won position, board light 1 turns on. Watch the evaluation

show you where the first piece of that type is located.
Steadily lit board lights indicate White pieces, and flashing lights indicate Black pieces.
Press the same Piece Symbol key repeatedly to see
the locations of more pieces of that same type. When
there are no more pieces of that type, a beep will sound.

been cancelled. Note that Non Auto Mode is also automatically cancelled whenever you press NEW GAME or
select one of the Teach Modes.
2.11 Playing Black From the Bottom
You may want to depart form the usual standard and
play the Black pieces from the bottom of the board, letting
the computer play White from the top. To do this, press
NEW GAME and then PLAY. The computer reverses
sides and makes the first move for White from the top of
the board!
In the diagram on page 5, you can see that the initial
piece set-up is different when you reverse sides. Notice,
in particular, that the Kings and Queens are positioned
differently. Be sure to set the board up correctly!
When you play Black from the bottom, the color indicator lights are also reversed (i.e., the 1 light will indicate
Black, and the 8 light will indicate White).

grandmaster play. If the current board position is in this
library, the computer plays a response to that position
from its memory, instead of thinking about the move. The
computer uses its openings library on all levels except
A1-A8 and B1-B8 (the Beginner/Fun levels, Infinite Levels
and the special problem solving levels).
Many players typically know just five or six opening
lines. Your chess computer will allow you to study and
learn over 100 moves of solid, Grandmaster-approved
opening theory! Try 1.c2-c4, 1.d2-d4, or even 1.Ng1-f3!
2.13 Voice Features to Remember
Remember these points concerning the voice:
openings library.
The computer’s library
• Volume is controlled with the Volume Control Slider.
• You can choose between voice output, beeps or
silence, if desired (see section 4.2).
• Press SAY AGAIN whenever you would like the
computer to repeat the last voice output.
2.14 Game Memory
You may interrupt a game at any time by switching to
STOP to turn the computer off. Play is then suspended,
and the computer will “remember” your position for up to
18 months (with fresh alkaline batteries). When you
switch on again, you can continue where you left off! To
conserve battery power, switch off when you interrupt
your game for more than a few minutes.
If you power your unit with the optional AC adapter,
you should still keep good batteries installed, to ensure
that memory contents are not lost if the unit is unplugged.
3. LEVELS OF SKILL
With 384 level settings to choose from (incorporating
the Teach Modes), you can learn and grow with this
chess computer! As shown in the chart of playing levels
on page 8, there are 64 unique playing levels, including
levels for casual play, Mate Finder and Combination
Finder Levels, Aggressive and Quiet Closed Levels, and
several different types of levels especially for beginners!
When you set the level, keep in mind that when the computer has more time to think about its moves, it gets
stronger and plays better–just like a human chess player!
Setting a Playing Level
Press LEVEL, and the computer lights the board
square corresponding to the currently set level. When the
computer is first turned on, it is set on Level H4 (10 seconds per move). As indicated in the chart, each of the 64
board squares corresponds to one playing level. After
pressing LEVEL, press a square to activate a level, using
the chart as a guide. When you press down on the desired square, the board lights turn on to indicate that
square. Press LEVEL to exit Level Mode.
For those levels which have Average Response Times
listed, note that the times are averaged over a large
number of moves. In the opening and endgame, the
computer tends to play faster, but in complicated middlegame positions, it may take longer to move.
3.1 Beginner Levels (A1-A8)
BEGINNER LEVELS AVERAGE TIME PER MOVE
Square A1...................... 1 second
Square A2...................... 2 seconds
Square A3...................... 3 seconds
Square A4...................... 4 seconds
Square A5...................... 5 seconds
Square A6...................... 6 seconds
Square A7...................... 7 seconds
Square A8...................... 8 seconds
The Beginner Levels are meant specifically for novice
players. On these levels, the computer restricts its search
so that it deliberately plays weaker and gives the beginning player a chance to beat the computer!
3.2 Fun Levels (B1-B5)
FUN LEVELS AVERAGE TIME PER MOVE
Square B1...................... 1 second
Square B2...................... 2 seconds
Square B3...................... 3 seconds
Square B4...................... 4 seconds
Square B5...................... 5 seconds
These unique “Fun Levels” are meant especially for
beginners and young players—these levels will allow
those who might otherwise never win a game of chess to
come up on the winning side for a change! On the Fun
Levels, your chess computer is much more “human” than
most other chess computers—it gives everyone a chance
to win, in a world where chess machines are typically
relentless and often quite difficult to beat. Although the
general consensus seems to be that computers never
make mistakes, on the five Fun Levels, this computer
actually does!
Various handicaps are built into the Fun Levels, demonstrating common mistakes made by beginners. Chess
books often advise of basic rules—warning not to give
away material, not to bring the Queen out too early, and
advising the development of pieces before starting an
attack. Yet players see their opponents breaking these
rules and getting away with it! The Fun Levels provide a
way of practicing the punishment of these typical mistakes, thus enabling the beginner to strengthen his game
against the human opponents he is likely to face.
Even after a player has mastered the Fun Levels, they
can still be a valuable training tool. A game can be started
on a Fun Level, for example, and, when the computer
makes a bad move, the player can switch to a normal
level and try to convert his advantage to a win, playing

against the stiffer opposition of a higher level.
Level B1 is the weakest level. On this level, the value
of material is set so that the computer will not only “hang”
pieces (leave pieces unguarded), but will also actually try
to lose material. Watching the computer throw away its
Queen would not even be uncommon on this level! Levels
B2, B3, and B4 are similar to B1, in that they also give
away material, but they do not do it as consistently. They
progressively start to consider the material worth of
pieces more and more, and Level B4 only occasionally
gives pieces away. On Fun Level B5, the computer does
not actually give away material—here, it plays more like a
beginner who has learned the basics of the game. On this
level, the computer makes mistakes such as bringing out
its Queen too early, leaving its pieces unguarded, and
opening itself up to threats of check and/or checkmate.
Why not try out all the Fun Levels—and try to learn from
the computer’s mistakes!

On the Infinite Level, the computer searches indefinitely, until it finds a forced mate, runs out of memory, or
until you stop the search by pressing PLAY. If the search
is halted, the computer makes the move it currently thinks
is best. Try experimenting with the Infinite Level—let the
computer analyze complicated positions for hours or even
days!
3.4 Combination Finder Level (B7)
Combination Finder Level PURPOSE
Square B7 ..........Solves chess puzzles
The Combination Finder Level is used for solving “mate
or a large win of material” problems. Here, the computer
looks for the shortest forced win of two pawns or more. In
order to come up with a solution, the computer must see
a win of enough material to be two pawns better than the
current position. If it finds such a solution, it will beep and
indicate its move.
If the computer reaches its search depth limit without
finding a solution, it beeps and the previously flashing
color indicator turns on steadily. To continue play, change
levels—then either press PLAY to have the computer

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 computer 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 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 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.

results in much weaker play, giving beginners and average 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!

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 position. With this type of play, the program also avoids attacks and keeps positions closed whenever possible.

In direct contrast to the levels described previously in
Section 3.9, on Levels G1-G8, the computer is much
more active and plays more aggressively. It will try to
open up positions by exchanging or sacrificing pawns,
and it will actively avoid piece exchanges to keep board
positions as complicated as possible! On these playing
levels, the computer also likes checks and direct attacks
on your pieces. Be prepared for anything!

The Normal Playing Levels are also this computer’s
strongest and most challenging levels! Whenever you
choose one of these levels, you are basically selecting an
average response time for the computer. On these levels,
the computer uses a Selective Search algorithm, allowing
it to quickly come up with move combinations which
would otherwise take much longer to find.
4. SPECIAL COACHING MODES
4.1 Teach Modes: Learn All About Tactics!
Your chess computer contains five built-in Teach
Modes. This feature allows you to learn basic moves and
master the tactics of the pieces, one at a time. For each
individual Teach Mode, the only pieces on the board are
Kings, pawns, and the selected piece type. This will help
beginners to concentrate solely on one piece at a time,
without losing focus and being distracted by other pieces
on the board!
To enter Teach Mode, press LEVEL. The computer
uses board lights to indicate the currently selected level of
play. If you want to change the level, press the corresponding board square, as described in Section 3. If you
do not change the level, the current level will remain in
effect. After deciding on your playing level, you are now
ready to choose the Teach Mode you would like to try out!
As shown in the Teach Mode Chart above, selecting
the piece you want to study is easy—simply press the
corresponding Piece Symbol key (QUEEN, ROOK,
BISHOP, KNIGHT, or PAWN). As indicated in the chart,
pressing a Piece Symbol key turns on a pair of board
lights to indicate the piece you have selected to study.
After making your choice, press LEVEL to enter your
selection into the computer. The computer is now ready
for a new game, using the newly selected Teach Mode
and playing level. Remember that the only pieces on the
board will be Kings, pawns, and the piece type you have
chosen to study!
Note that the KING key is reserved for the standard
game, using all 32 chess pieces. When KING is pressed
in Teach Mode, board lights 2 and 7 turn on to indicate
the standard board. Pressing LEVEL to exit Teach Mode

at this point simply returns you to a new game, playing
with all the pieces.
Please also note the following points:
•
If you press LEVEL and then decide not to change
the playing level or Teach Mode, simply press
LEVEL again, and the current game status will
remain as is.
• If you do not press a square to select a new level,
the current level will remain in effect.
• If NEW GAME is pressed during any game, the
computer will switch back to the standard game,
with the current playing level still in effect.
• If you accidentally press any piece symbol key in
Level Mode, you will lose the current game after
exiting Level Mode. To continue with the current
board, press any square key, TAKE BACK, NON
AUTO, VOICE/COACH, PLAY EVALUATE, HINT
or SAY AGAIN to deselect the Teach Mode before
exiting Level Mode.
4.2 Voice/Coach Levels: Practice Your Game!
Your chess computer has four different Voice/Coach
Levels, which are accessed by repeatedly pressing
VOICE/COACH. Each time this key is pressed, a corresponding board light turns on briefly (E-H), as noted
below. To verify which Voice/Coach level is in effect at
any time, simply press any square then VOICE/COACH—
and the board light will identify the current level.
• Coach Level E: Voice On, with Full Coach
Level E is a special level which encourages beginners
to improve their skills and understanding of the game of
chess. On this level, the computer gives you all possible
voice output, and also gives you important additional
information during the game:
• When one of your pieces is in danger, i.e., the
computer is likely to attack it on the next move, the
computer will alert you to this. It may tell you, for
example, to Watch your Bishop! It will also flash
the square of the endangered piece for a few seconds. You may continue the game after the square
has stopped flashing by either making your next
move, or by pressing TAKE BACK to take back
your last move and making another one.
• Voice/Coach Level F: Voice Only
When you select this level, board light F turns on
Board Light

briefly. Here, you are choosing to play a normal game of
chess, with all voice output—but with the Coach functions
turned off.
• Voice/Coach Level G: Beeps Only
Board light G indicates a level where the computer
uses beeps to signify moves, keypresses, and other
game activity. The voice will not speak at all when you
select this level, and there are no coaching functions.
Note that there is no beep sound on verifying the piece.
• Voice/Coach Level H: Silent Mode
Choosing Level H gives you completely silent game
operation—no voice, and no beeps. Coaching features
are also turned off. When playing without sound, be sure
to watch the board lights carefully during the game!
