INTRODUCTION
Thank you for choosing this unique computer as your new chess
partner and opponent. This chess computer will give you countless
hours of valuable chess instruction and exciting game play! As the
computer patiently guides you and teaches you about this great game,
your chess skills are bound to improve. The voice will follow your every
move, occasionally even offering helpful advice and encouragement.
This is interactively at its best—watch, listen, and learn as you play!
Your computer knows the rules of chess. For those who are new to
the game, we have enclosed an overview of the rules. We hope this
will help you to understand the game better and get a feel for the
strategies involved. For more detailed information and further study, we
suggest a visit to your local library, where you are sure to find a wealth
of interesting chess books!
1. GETTING STARTED: THE BASICS
1.1 First, Install the Batteries
Your computer runs on four “AA” (AM3/R6) batteries. For longer
battery life, use fresh alkaline. Slide the GO/STOP switch to GO, and
then insert the batteries as shown in the Quick Start. After a short selftest, a
Welcome
is ready to play! If the unit doesn’t respond, reset the computer by
using 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.
See “KEYS AND FEATURES AT A GLANCE” for an itemized
overview of your chess computer’s main points!
1.2 Ready to Play? Here’s How!
Follow these steps to start a game:
a.Switch to GO to turn the unit on, if you haven’t already done so.
b.Set up the pieces in their starting positions, with the White pieces
nearest to you, as shown in the Quick Start. Press NEW GAME;
the computer confirms by announcing
c. To make a move, lightly press down on the piece you want to
move until you hear the voice identify that piece. The sensory
chessboard registers your move, and two board lights turn on to
indicate the piece.
d.Take the piece and gently press it down into the hole of the
square you want to move to. A beep will sound, and the computer
will then start thinking about its move.
At the beginning of a game, the computer often replies instantly on
many levels, playing moves directly from its openings library (see
Section 2.12).
1.3 The Computer Makes Its Move
When the computer moves, it beeps and turns on two board lights
indicating the horizontal row and vertical column of the piece it wishes
to move. Press this piece down gently on the square.
The computer then uses the board lights to show you where the
message will greet you, signalling that the computer

piece should go. Move the piece to the indicated square and press the
piece down. Once you have pressed this square, you have completed
the computer’s move!
See the “QUICK START” for an example of how the board lights
would indicate a computer move from e7 to e5!
1.4 Change Your Mind? Take Back!
If 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, and the
computer will announce the move to be taken back (e.g.,
back Knight move
through the take-back. The to square of the last move lights first—
press the indicated piece down on that square. The computer then
shows you where the piece came from. Press the piece down on the
from square to complete the take-back. Repeat this procedure to take
back more moves, up to a total of six individual moves.
). The computer also uses board lights to guide you
Black takes
When taking back captures or castling maneuvers, the computer will
remind you which pieces should be put back on the board! It does so
by turning on board lights to indicate the position. It also announces the
color and type of the captured piece.
1.5 Game Over? Start a New Game
Whenever you finish a game (or if you decide to abort your current
game), 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
memory, be careful not to press this key by mistake!
1.6 Too Easy/Hard? Change Levels!
When the computer is first turned on, it is set to Level H4 (ten
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 levels, press a
board square to activate your desired level, using the Level Chart in
Section 3 as a guide. Press LEVEL again to exit Level Mode.
1.7 Voice On/Off? It’s Your Choice!
Your computer’s informative and entertaining voice output is on by
default, and the Volume Control Slider sets the desired volume. How-
ever, if you would rather not have the voice on, you have other options!
As noted in Section 4.1, you can choose to hear only beeps, or 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
SAY AGAIN on your turn to have the last message repeated. Note the
following exceptions: If you press SAY AGAIN in Verify Mode or when
the computer is displaying a hint on your turn, the computer will simply
return to normal playing mode. Also, SAY AGAIN is disabled if the
Voice Coach Level is set to G or H, or when you are in Level Mode.
2. ADDITIONAL 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
captures and special moves, such as castling or pawn promotions.
Captures: To capture, press down lightly on the piece you want to
move—the voice will identify that piece. Take the captured piece off the
board, and press your piece on the square of the captured piece. The
capture will be announced, as in
En Passant: In an en passant capture, the computer uses board
lights to remind you to remove the captured pawn. Press down on the
captured pawn before removing it from the board. Although beginning
players are often confused when this type of capture occurs, the voice

example), and the to square flashes, press the corresponding Piece
Symbol key (the BISHOP key, in this case) to acknowledge the underpromotion, and the to square lights will turn off. If you have the voice
turned off and the computer underpromotes, check its chosen piece by
pressing the Piece Symbol keys in succession—the key which turns
the flashing to square off indicates the correct piece. Don’t forget to
replace the computer’s pawn with its new piece or make a distinguishing mark on it.
Castling: The computer automatically recognizes castling after the
King is moved. After you have pressed the King down on its from and
to squares, the computer announces
to remind you to move the Rook. Press down on the Rook’s indicated
from and to squares to finish the castling move.
2.3 Illegal Moves/Wrong Moves
Your computer will never accept an illegal move. If you attempt such
a move, the computer will announce your error! If you press the wrong
to square, you hear

consecutive three-fold repetition draw occurs, the voice says

2.5 Need Help? Ask for a Hint!
Whenever you need help, press SMART HINT on your turn, and the
computer will give you a move suggestion! If it thinks moving your
Knight from g1 to f3 is the best move, for example, it uses the board
lights to indicate that move, and tells you to
that you will get a hint in around five seconds no matter which level you
are on, since the hint move is based on a special “Best Play Level”
rather than the current level. So—you’ll always get immediate feedback
whenever you’re in need of 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 Search
To interrupt the computer while it is thinking, press PLAY—it will
then 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 it keeps thinking indefinitely

On the Mate Finder and Combination Finder Levels, pressing PLAY
does not cause the computer to make a move. Instead, it sounds a
double beep to indicate that it was interrupted before it found a mate or
solution. To continue your game, switch to another level.
2.7 Changing Sides with the Computer
To change sides with the computer, press PLAY when it is your turn
to move—and the computer will make the next move for your side.
To have the computer play 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!
See “WATCH THE COMPUTER THINK!” for a quick reminder of
which keys activate these special features!
Position Evaluation: To get the computer’s evaluation of your
position, press EVALUATE while the computer is thinking.
Note that the evaluation feature is not valid on the Mate Finder and
Combination Finder Levels, because of their special search algorithms.
Positions are evaluated on a scale from 1 to 8, as indicated by
board lights 1 through 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, 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
change as the computer searches deeper and considers more moves!
Display Computer’s Current Move: To see the move the computer
is currently considering, press and hold down DISPLAY MOVE while
the computer is thinking. The move is indicated with flashing board
lights—the from and to squares flash alternately. Watch carefully, and
you may see the computer change its mind about a move!
Note that
Display Move is not available on the Mate Finder and Combination
Finder Levels.
2.9 Verifying Piece Positions
See “PRACTICE USING VERIFY MODE!” for an illustrated
example—follow the steps, and you’ll see how easy it is!
If you should knock over the pieces, or if you think your position
might be wrong, you can have the computer verify the piece locations
for you! On your turn, press one of the Piece Symbol keys. The computer will identify that piece by name, and it will use the board lights to
show where the first piece of that type is located. Steadily lit board

2.11 Playing Black from the Bottom
See “TRY BLACK FROM THE BOTTOM!” for a diagram that
shows you how to set up this special board position!
You may want to depart from the usual standard and play the Black
pieces from the bottom of the board, letting the computer play White

Notice, in particular, that the Kings and Queens are positioned differently.
When you play Black from the bottom, the color indicators are also
reversed—the 1 light indicates Black, and the 8 light indicates White.
2.12 Book Openings
At the beginning of a game, the computer often replies instantly on
many levels, because it is playing moves from its
computer’s library includes the major openings and many positions
from Grandmaster play. If the current board position is in this library,
the computer plays a response to that position from memory, instead of
thinking about the move. The openings library is used on all levels
except A1-A8 and B1-B8 (the Beginner/Fun 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

openings library.

2.13 Game Memory
You may interrupt a game at any time by switching to STOP to turn
the computer off. Play is suspended, and the computer will “remember”
your position for up to two years (with fresh alkaline batteries). When
you switch on again, continue where you left off! To conserve batteries,
switch off when you interrupt a game for more than a few minutes.
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
on the Chart of Playing Levels, 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 meant 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!
See the “CHART OF PLAYING LEVELS” to get an overview of
all the levels at a glance. We’ve also included level selection tips!
Selecting 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 (ten 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 will indicate that square. Press LEVEL to exit Level Mode.
See “HERE’S HOW TO SET A LEVEL!” for a step-by-step look
at setting a specific level,
For levels indicating Average Response Times, 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.
HERE’S HOW TO SET A LEVEL!
Let's say you want to set the easiest Fun Level. Just follow the
steps below:
1. Press LEVEL. Next,
look at the Chart of
Playing Levels and find
the Fun Levels. Y ou’ll see
that Fun Level 1 is on
Square B1.
2. Take a piece and press
it briefly into the hole on
Square B1 to select that
level. You’ll see the B and
1 lights turn on, indicating
Fun Level 1.
3. Press LEVEL again to
exit Level Mode. Now you
can start playing on your
newly selected level!
For details on all the levels,
see Section 3.

The Beginner Levels are meant specifically for novice players. Here,

and gives the beginning player a chance to beat the computer!

FUN LEVELS AVERAGE TIME PER MOVE
Square B1 ............................ 1 second

Square B5 ............................ 5 seconds
The 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
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 all 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 Fun Level. Here, the value of material is set
so that the computer will not only “hang” its pieces (leave its 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 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 or checkmate.
Why not try out all the Fun Levels—and learn from the computer’s
mistakes!
3.3 Infinite Level
INFINITE LEVEL TIME PER MOVE
Square B6 ........................ No time limit
On the Infinite Level, the computer searches indefinitely, until it finds
a forced mate, run out of memory, or you stop the search by pressing
PLAY. If the search is halted, the computer makes the move it currently thinks is best. Experiment—let the computer analyze positions
for hours or days!
3.4 Combination Finder Level
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 beeps and
indicates 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
MATE FINDER LEVEL PURPOSE
Square B8 ................ Solves mate problems
If you have a position where there might be a mate and you want
the computer to find it, set the computer on this level! It will search for a
forced mate, and will only play a move if it finds a mate. The computer
can solve mates in up to four moves. If there is no mate present or if
the computer can’t find a mate, it beeps and the previously flashing
color indicator turns on steadily. Continue play by changing levels.

or the lower Fixed Depth Levels. These
levels all restrict the computer’s search

you a chance to learn more about the

from easy all the way up to a more difficult

3.6 Practice Levels
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 skills!
On these levels, the computer plays 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 they may easily be attacked.
3.7 Tactical Levels
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 since it
uses a different search method. On the Normal Playing Levels, a
Selective Search algorithm is used. This allows the computer to see
combinations that would otherwise take much longer to compute. On
the Tactical Levels, the computer switches to a powerful Brute Force
Search—which helps minimize the risk of an occasional oversight.
3.8 Fixed Depth Levels
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 a certain number of
ply.
A ply is an individual move, or a move for
either side. As an example, on Level E1, the computer only searches to
a depth of one ply—it only looks ahead one individual move. This
results in weaker play, giving beginners 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
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 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.
3.10 Aggressive Game Levels
AGGRESSIVE GAME LEVELS AVERAGE TIME PER MOVE
Square G1 ............................ 1 second
Square G2 ............................ 2 seconds
Square G3 ............................ 5 seconds
Square G4 .......................... 10 seconds
Square G5 .......................... 30 seconds
Square G6 ............................ 1 minute
Square G7 ............................ 2 minutes
Square G8 ............................ 3 minutes
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
10
aggressively. It will try to open up positions by exchanging or sacrificing
pawns, and will actively avoid piece exchanges to keep positions as
complicated as possible! On these levels, the computer also likes
checks and direct attacks on your pieces. Be prepared for anything!
3.11 Normal Playing Levels
NORMAL PLAYING LEVELS AVERAGE TIME PER MOVE
Square H1 ............................ 1 second
Square H2 ............................ 2 seconds
Square H3 ............................ 5 seconds
Square H4 .......................... 10 seconds
Square H5 .......................... 30 seconds
Square H6 ............................ 1 minute
Square H7 ............................ 2 minutes
Square H8 ............................ 3 minutes
The Normal Playing Levels are the strongest and most challenging
levels. When you choose one of these levels, you are basically selecting an average response time for the computer. Here, the computer
uses a Selective Search algorithm, allowing it to quickly come up with
move combinations that would otherwise take much longer to find.
4. SPECIAL COACHING MODES
4.1 Voice Coach Levels
See the “VOICE AND COACHING OPTIONS” chart for an
overview of your options!
The four Voice Coach Levels are accessed by repeatedly pressing
VOICE COACH. Each time this key is pressed, a corresponding board
light turns on briefly (E-H), as described below. To verify which Voice
Coach Level is in effect at any time, simply press any square and then
VOICE COACH—a board light will identify the current level.
• Voice Coach Level E: Voice On, with Full Coach
Level E encourages beginners to improve their chess skills. On
this level, the computer gives you all possible voice output, along
with full coaching features. 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

press TAKE BACK to take back your last move and make
another one.
• Voice Coach Level F: Voice Only
When you select this level, board light F turns on 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 on this level, and there are no coaching functions.
Note that beeps do not sound when verifying pieces.
• Voice Coach Level H: Silent Mode
Choosing Level H gives you completely silent game operation—
no voice and no beeps. Coaching features are also off. When
playing without sound, be sure to watch the board lights carefully!
4.2 Teach Modes
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 on one piece at a time, without losing
focus and being distracted by other pieces on the board!
See the “TEACH MODES AT A GLANCE!” chart for a step-by-
step example of how to select the Teach Modes!
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 a board square as described in Section 3. If
you do not change the level, the current level will remain in effect. After
deciding on the level, you are ready to choose a Teach Mode.
Selecting the piece you want to study is easy—simply press a Piece
Symbol key (QUEEN, ROOK, BISHOP, KNIGHT, or PAWN). As shown
in the “TEACH MODES AT A GLANCE” Chart, pressing a Piece
Symbol key turns on a pair of board lights to indicate the piece you
have chosen to study. Finally, 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—the only
pieces on the board will be Kings, pawns, and the piece type you have
selected!
Note that the KING key is reserved for the standard game, using all
32 pieces. When KING is pressed in Teach Mode, 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 pieces.
Please also note the following points in regard to the Teach Modes:
TEACH MODES AT A GLANCE!

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 a Piece Symbol key in Level Mode, you
will lose your current game after exiting Level Mode. To prevent
this and retain your current board position, press any key (except
NEW GAME, LEVEL, or a Piece Symbol key) to deselect Teach
Mode before exiting Level Mode.
