INTRODUCTION
Congratulations! You are now the proud owner of one of
the most unique and exciting chess computers ever. This
talking computer, with its vast array of special features and
interesting game options, is a real breakthrough in the field
of computer chess. The human-like interaction is guaranteed
to amaze you—this machine is unlike any other. Over twenty
hours of human voice will guide you, train you, and keep you
company while you learn more than you ever imagined you
could about the exciting game of chess. From the friendly
advice on what to do in a certain position, to the warnings
when you’re about to make a mistake, to the in-depth tutorials which take you by the hand and teach you as never
before—with this computer by your side, chess will never be
the same again!
See the “KEYS AND FEATURES” diagram for an
itemized overview of the computer’s main points.
Your computer knows and follows all 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 understand
the game better and get a feel for the strategies involved. For
more detailed information, 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 or Adapter
Your chess computer runs on six “C” (AM2/R14) batteries.
Insert the batteries as indicated in the
front of the manual, making sure to observe the correct
polarity. Use fresh alkaline batteries for longer battery life.
Please use only the adapter specified in Section 8.3, as
using any other adapter could damage the computer and will
invalidate your warranty. Please also read the precautionary
information regarding adapter use in Section 8.2. When
using an adapter, first plug it into a wall outlet, and then into

memory contents are not lost, keep good batteries installed
in the unit even when you are using an AC-DC adapter.
To turn the computer on, press GO/STOP. After a brief
start-up procedure, a welcome message will 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 down into the hole marked ACL in the base of the unit
for at least one second. This will reset the computer.
To conserve energy and extend battery life, an Auto
Power Down feature will cause the computer to turn
itself off automatically if left idle for about 15 minutes.
Important: To ensure that the computer’s

as a confirmation! Set up the pieces in their
starting positions, with the White pieces nearest to you,
as shown in the
Quick Start.
c. To make a move, lightly press down on the piece you
want to move until you hear the voice identify that
square. The sensory board registers your move, and
the light in that square turns on. The display also shows
the color, the piece, and the square that was pressed.
d. Take the piece and press it down on the square to
which you are moving. That square will be announced,
and the computer will start thinking about its move.
At the beginning of a game, the computer’s reply is often
instantaneous on many levels, because it is playing moves
which are stored in its openings library (for details, see
Section 2.8).
1.3 The Computer Makes Its Move
When the computer moves, it says
shows its move in the display. It also turns on the light in the
square it is moving from. Press the indicated piece down
gently on the from square until the square is announced and
the light in the to square comes on. Move that piece to the to
square and press the piece down to complete the computer’s
move.
Depending on the sound and coaching options currently
in effect, you may also hear other game information during
these early moves. The computer might identify the opening
line and refer you to a tutorial for that specific opening! Or, if
it thinks you need help with rules or strategies, it may offer
advice, referencing related tutorials. You simply couldn’t ask
for a more helpful, patient, and knowledgeable chess tutor!

and
1.4 Change Your Mind? Take Back
To take a move back for either side, simply retract the
move on the board by moving the piece back to the square
from which it came, pressing down on the squares as you go.
The take-back is announced, the display shows you the
move, and the board lights alternately turn on the to and
from squares to guide you through the take-back. After you
take back one move, the computer will indicate the next
move that can be taken back. You can take back up to 64
individual moves. To resume play at any point, simply make
another move on the board.

Alternatively, you may press BACK when it is your turn to
move, and the computer will guide you through the take-back
procedure as described above.
When you take back captures, castling maneuvers, or
pawn promotions, the computer will remind you of pieces to
be put back on the board! It uses the display, board lights,
and voice to show the piece and position. Press the piece
down on the indicated square to complete the take-back.
1.5 Game Over? Start a New Game
Whenever you finish a game (or if you decide to abort
your current game), you may reset the computer to start a

1.6 Too Easy/Hard? Change Levels
When the computer is first turned on, it is set to Playing
Level 63, with an average response time of five seconds a
move. However, you can choose from 100 different levels of
play! For detailed descriptions of all levels and instructions
on how to change levels, see Section 3.
1.7 Voice On/Off? It’s Your Choice
Your computer’s informative and entertaining voice is on
Sound Level 2
controls the volume. However, if you would rather have more
voice output, or less, or if you want to turn the sound off
completely, you do have those options! See Section 5.1 for a
complete rundown of all your choices.
Many of the voice examples used in this manual are
based on the computer’s default settings. Depending on
the sound and coaching options you choose in Section
5, you can have as much or as little voice interaction as
you wish!
By the way, if you don’t hear what the computer says at
any point, simply press SAY AGAIN on your turn to have the
last phrase repeated. Pressing this key repeatedly may also
give you other previously spoken information. Note that you
can use this feature regardless of the current Sound Level—
pressing SAY AGAIN will always repeat the phrase(s) that
would have been spoken on Sound Level 4.
by default, and the Volume Control Slider
SPECIAL NOTES REGARDING SOUND
• Control the volume with the Volume Control Slider.
• The Sound Levels determine the amount of voice
interaction, beeps or silence (see Section 5.1).
• The Coach Levels determine the amount of voice
coaching, regardless of the Sound Level setting
(see Section 5.1).
• If you don’t move the computer’s piece on the
board soon after it has announced its move, it
intermittently sounds a series of reminder beeps!
You’ll appreciate this feature on levels where the
computer thinks for a long time—you can walk
away from the game and the repeated beeps will
alert you when the computer has moved! These
beeps also occur at other times—whenever you
hear them, check the board and display to see
what the computer is expecting you to do!
• When you take a tutorial, the current Sound and
Coach Levels may be changed, as required by
that tutorial. These Sound and Coach Levels will
remain in effect upon exiting Tutorial Mode.
• Press SAY AGAIN to have the last phrase re-
peated. Pressing this key repeatedly may also
give you other previously spoken game information. No matter which Sound Level is in effect,
pressing SAY AGAIN will always repeat the

piece. It also displays the promotion square and turns on that
board light. Press a Piece Symbol Key (%, $, #, or @) to
identify your new piece, and the pawn promotion or
underpromotion is complete. The computer recognizes your
new piece immediately, and begins thinking about its next
move. Remember to change your piece on the board!
• When the computer promotes a pawn, it indicates its
move as usual, but the display shows both the pawn and its
intended promotion piece. Simply make its move by pressing
the from and to squares as usual. Don’t forget to replace the
computer’s pawn with its new piece.
2. ADDITIONAL FEATURES
2.1 Whose Turn? Check the Display!
When the computer plays Black, it flashes a black square
in the display while it is thinking. After it has moved, a white
square is displayed steadily to show that it is now White’s
turn to move. This feature allows you to tell at a glance
whether or not the computer is currently thinking, and which
side is to move!
2.2 Captures and Special Moves
Captures: To capture, press down lightly on the piece you
want to move, take the captured piece off the board, and
press your piece on the square of the captured piece. Captures are displayed as in G6•H5.
En Passant: In an en passant capture, the computer
reminds you to remove the captured pawn and tur ns on the
light in that square. Press down on the captured pawn before
removing it from the board.
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 reminds you
to move the Rook. Press down on the Rook’s indicated from
and to squares to finish the castling move. A Kingside castle
is displayed as 0-0, and a Queenside castle as 0-0-0.
Pawn Promotion:
• When you promote a pawn, first press your pawn down
on the from
square, the computer will prompt you to select a promotion
square, as usual. As soon as you press the to
2.3 Illegal Moves
Your computer will never accept an illegal move. If you
attempt such a move, the computer will announce your
mistake! If you press the wrong to square, you will hear
Error
, and the display and a board light will indicate the
square the piece came from. To clear the illegal move, press
the piece back down on its from square. If you press down
on the wrong color piece, you will again hear
computer will simply disregard the square you pressed.
If you don’t execute a computer move correctly (if you try
to move its piece to the wrong square), you also get an error
message and a board light identifies the square the piece
should move to. Check the display again for the correct
move. If the computer wants to move its pawn from c7 to c5,
for example, and you press down on c7 and then c6, the
display shows ER:C5 briefly, pointing out your error. The
display then returns to showing the move again (C7-C5),
and the computer expects you to press down on Square c5
to complete its move.
If you press down on a piece and the from square appears in the display, but you decide not to make that move,
simply press down on that same square again to cancel the
input. Then make another move of your choice. If you change
your mind after entering your whole move, take the move
back as described in Section 1.4.
2.4 Check, Mate, and Draw
When a King is in check, the computer will say
After the move is made, CHECK flashes in the display for a
few seconds, along with the checking move. The display then

reverts back to showing the clock. Note that when the computer is in check, the display will revert back to normal
immediately after the CHECK display.
If the computer discovers a forced mate against its opponent, it first displays its move as usual. After the move has
been made on the board, the computer flashes a mate
announcement along with the move for several seconds
(e.g., =in2 for a mate in two moves). The display then
goes back to showing the clock.
When a game ends in checkmate,
nounced, and the display flashes MATE (along with the
mating move) for a brief time after the move has been made.
The display then goes back to showing the clock.
The computer recognizes draws by stalemate, three-fold
repetition, and the 50-move rule. The voice will announce the
draw, and the display flashes End (along with the drawing
move) for a brief time after the move has been made. The
display then goes back to showing the clock.
2.5 Need a Hint? Just Ask!
Whenever you need help, the computer is glad to oblige!
Press HINT/INFO on your turn, and the computer will display
a suggested move. Displaying this hint usually takes one to
five seconds, but can sometimes take longer. To accept the
hint, make that move on the board. To make a different move,
disregard the hint and make a move of your own, or press
NO/X to cancel the hint display. Note: The hint move is based
on an optimum level rather than the current level.
2.6 Interrupting the Search
To interrupt the computer while it is thinking, simply press
??

found so far. This feature can be useful on the higher levels,
where the computer can take a long time to move, and on

??
the board, one move after another. Study its strategies—you
might improve your own game!
2.8 Book Openings
At the beginning of a game, the computer’s reply is often
instantaneous on many levels, because it is playing moves
from its
most major openings and many positions from grandmaster
play. If the current board position is in its library, the computer plays a response to that position from memory, instead
of thinking about the move. The computer uses its openings
library on all levels except the Problem Solving Levels and
certain Fun Levels.

Mode Options to study individual openings. And, in Section
4, you’ll find in-depth voice tutorials on many of the most
popular openings—it’s a great way to strengthen your game!
2.9 Thinking on the Opponent’s Time
replies to your moves immediately, even in the middle of
games played on the higher levels. This is because the
computer thinks on your time, using the time you are contemplating your next move to think ahead and plan its own

strategies. It tries to anticipate the move you are likely to
make, and calculates its responses for that particular move
while you are still thinking. If the computer has guessed
correctly, there is no reason for it to keep on calculating—it
immediately plays the move it has already found!
Note that the computer does not think on the opponent’s
time on the Fun Levels.
2.10 Game Memory
You may interrupt a game at any time and turn the unit off
by pressing GO/STOP. Play is then suspended, and the
computer stores your current position and game (up to 64
individual moves) for up to one year. When you switch back
on again, you can continue right where you left off!
Tip: If you power your unit with an AC-DC adapter, you
should still keep good batteries installed, to ensure that
memory contents are not lost if the unit is unplugged.
2.11 Auto Power Down
The Auto Power Down option is an energy-saving feature,
causing the computer to automatically turn itself off after
about 15 minutes if no keypresses or moves are made
during that time. To continue where you left off, press GO/STOP to turn the computer back on.

3. PLAYING LEVELS
See “PLAYING LEVELS AT A GLANCE” for a listing of
all 100 playing levels.
Your chess computer has 100 unique playing levels to
choose from. These levels are divided into two basic groups:
• 60 HANDICAP LEVELS: These special Fun Levels offer
beginners and average players a chance to learn about
chess and build their skills. On many of the Fun Levels,
you’ll even see the computer make mistakes on purpose—so that you can learn from it!
• 40 COMPETITION LEVELS: These playing levels offer
intermediate and more advanced players a great variety!
They include levels for tournament play, casual and
tactical play, problem solving, and speed chess. 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
See “WANT TO SET A PLAYING LEVEL? HERE’S
HOW!” for a detailed example of setting a level.
For a complete overview of all 100 playing levels, please
refer to the Level Chart. The levels are also described individually in this section.
Press LEVEL to enter Level Mode, and the computer
displays the currently selected level. Use the FWD and
BACK keys to increase or decrease the levels by one. As a
shortcut, press LEVEL repeatedly to skip over ten levels at a
time. While changing levels, you will see the display toggle

and exit Level Mode.
If you have pressed LEVEL to verify the level but do not
wish to actually change levels, press NO/X to exit Level
Mode. This returns you to normal play without changing the
level or clock settings, even while the computer is thinking.
Please also note the following, in regard to setting levels:
• The level can be changed at any time during the game.
• Changing the level always resets the chess clocks.
• If you change the level while the computer is thinking,
the clock is reset and the current search is aborted. If
LEVEL is pressed while the computer is thinking but the
level is not changed (that is, if NO/X is pressed instead
of YES/

These unique “Fun Levels” are strongly handicapped and
meant primarily for beginners and younger players. On these
levels, your 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 some
of these levels, this computer actually does! The Fun Levels
cover a rating range from 0 to 1900 ELO points.
By the way, if you don’t do so well on these levels, the
computer will automatically suggest tutorials for you!
Various handicaps are built into some of these levels,
demonstrating common mistakes made by beginners. You
may see the computer deliberately ignore the material worth
of the pieces, and ignore key concepts such as pawn str ucture, centrality, mobility, and King safety. It may overlook or
walk into mates, develop its Queen too ear ly, and make
impulsive captures and checks. Chess books often advise of
basic rules, 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!
On some of the weaker Fun Levels, the computer will not
only leave pieces unguarded, but might also actually try to
lose material. Watching the computer throw away its Queen
would not even be uncommon! As the levels get higher, they
give away material less consistently. They progressively start
to consider the material worth of pieces more and more, and
eventually only occasionally give pieces away. On the higher
Fun Levels, the computer doesn’t actually give away material—instead, it plays more like a beginner who has learned
the basics of the game. You might still see it make mistakes
such as opening itself up to threats of check or checkmate.
Why not try out all the Fun Levels—and try to learn from the
computer’s mistakes.

The first ten Competition Levels are meant for casual
chess play. Whenever you choose one of these levels, you
are selecting an average response time for the computer. On
these levels, the computer uses a Selective Search, allowing
it to quickly come up with move combinations which would
otherwise take much longer to find.
Note that the response 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.

The Tournament Levels require you to make a certain
number of moves within a given amount of time. If a player
exceeds the allotted time for a given number of moves, the
computer announces this (e.g.,

SOME TIPS FOR YOU
• Are you a beginning player?
Fun Levels. These levels restrict the search depth
and contain built-in handicaps, resulting in weaker
play. This gives you a chance to learn about the
game and perhaps even beat the computer! These
60 levels get progressively more difficult as they go
up—as you conquer each level, go on to the next!
• Are you an intermediate or more advanced
chess player?
Try the Casual Play Levels, which
range from easy all the way up to a more difficult
three-minute response time on Level 70. For real
excitement, challenge the computer to some fastpaced games of Speed Chess! And, if you are up to
the most demanding levels, be sure to have a go at
the Tournament Levels.
• Learn by watching the computer!
styles of play based on the type of search. Use
Playing Mode to switch between the Selective
Search and Brute Force Search algorithms—look
for differences in how the computer plays!
•Want to experiment?
Use the Problem Solving
Levels to solve problems up to mate in eight—try
searching from a position in one of your own
games, or set up an actual mate problem. Select
the Infinite Level or the Tactical Level and have the
computer analyze complicated positions for hours
or even days! Turn on the Rotating Display Options
and watch its thought process in the greatest detail!
86 30 minutes ..................................... L 86 0:30:99

89 90 minutes ..................................... L 89 1:30:99
90 100 min utes..................................... L 90 1:40:99
On the Speed Chess Levels (also called “Sudden Death”
Levels), you set the total time for the whole game. If the
game time is exceeded, the computer announces this (e.g.,
Black loses on time)
and flashes timE along with the
elapsed time to show that the game is over.
If you select a Speed Chess Level, you may want to set
the clocks to display countdown time instead of elapsed time
(see Section 5.1). When the time runs out, the countdown
clock automatically reverts back to the normal clock display.

Selecting one of these levels activates a special mate
finder program. If you have a position where there may be a
mate and you would like the computer to find it, set the
computer on one of the Problem Solving Levels. Your chess
computer can solve mates in up to eight moves. Mates in
one to five are usually found quite quickly, whereas solutions
taking six to eight moves may take quite some time. If there
is no mate present or the computer cannot find a mate, it will
display a series of dashes (-----). You may continue to play, if
desired, by switching levels.
