1. Inserting batteries & starting the computer the first time
Place the device upside-down on a flat surface. You will see the battery compartment on
the underside of the device.
•Open the battery compartment by sliding its lid in the direction of the arrow.
•Insert four AA batteries (R6/LR6) into the compartment, paying attention to the
polarity: the “positive” terminal of each battery, labelled “+”, must match up with a
“+” inside the battery compartment.
•Close the battery compartment.
•Make sure that the computer’s ON/OFF switch is set to ON. You will find this
switch on the underside of the unit below row 8 of the chessboard, next to the
input for the power adaptor.
•The computer will now start automatically.
Note: if the red “low battery” symbol appears in the bottom line of the LCD (liquid crystal
display), the batteries should be replaced as soon as convenient.
Alternatively ChessGenius can be powered by a mains adaptor with a centre positive plug
and maximum 5V output. The socket for the plug is on the underside at the rear, next to
the ON/OFF switch. The suitable M811 Power Supply can be bought at
computerchess.com or via the retailer from whom you bought your chess computer.
2. Choose the language for the screen text
Once the batteries are correctly inserted, the computer gives a
characteristic sound signal, and the display shows a list of
languages. The first one is “highlighted” against a black
background.
By repeatedly pressing the or button, you can highlight each
language in turn, and bring further languages onto the display;
there are 14 in all.
When the desired language is highlighted, press the RED or GREEN
button to select it.
Note: If the language list fails to appear, execute a Reset of the Computer:
•Hold down the RED button.
•Insert a thin object (e.g. paper clip) into the opening marked RESET on the
underside of the unit, and press with it once.
•Release the RED button when the language list appears.
If you have selected the wrong language by accident, carry out the reset procedure then
select the correct one.

3. Play a game
Once the language is selected, the screen shows the chessboard
with the pieces in the starting position.
You can now begin a game with the computer. Place the chess
pieces (supplied with the package) on the membrane board, with
White at the end next to the controls. We suggest you play your
first game with White.
Note: If you don’t press a control button or a square on the
chessboard during an interval of 5 minutes (or 1 minute if the
batteries are low), the display is “dimmed”. The next press restores
the brightness.
Play your move
Press with your piece on the squares it is moving from and to. The computer gives a
“click” in acknowledgement.
To castle: make the king’s move, then the rook’s move.
For an en passant capture: move the capturing pawn, then press the square of the
captured one.
For pawn promotion:
•Carry out the pawn’s move.
•Using the / buttons, display the desired piece type.
•Press RED, GREEN or the promotion square.
Square shown in yellow on the LCD: You have selected this as the “from” square. (To
cancel, press the square again.)
Square shown in red: You are prompted to press this square to carry out the computer’s
move or to complete your own “special” move (castling etc.).
If you try to make an illegal move (or press any wrong square or button), you hear a low-
pitched sound. Simply continue as normal.
Execute the computer’s move
The move is announced by a sound signal. The LCD shows the piece switching between
the “from” and “to” squares, and the move appears in notation at the bottom of the
display.
To execute the move, press each square as prompted by the red highlighting. A “ping”
announces check.

Retracting and replaying moves
To retract a move, press the button, then move the piece back, pressing the squares
indicated in red. Then if the move was a capture, you will be prompted to press the
captured piece down as you replace it.
To retract a sequence of moves, repeat the above procedure. Alternatively: to retract (e.g.)
5 moves, press five times, then press the squares to take back the concluding move of
the sequence.
A move or sequence that you have retracted can be replayed in a similar manner, using 
instead of .
At any point you may resume play from the position on the board, by making a new move
or instructing ChessGenius to do so (see Section 8: “Move now”)
Meaning of symbols in the bottom line
A smiling face indicates that you are to move. A pair of faces shows that the computer is
in “2 Players” mode (see Section 8).
A rising/falling column shows that ChessGenius is thinking about its move.
The bar below the symbol indicates which colour moves next.
Info and analysis windows during the chess game
When “i” is shown at the bottom left, the RED button cycles round
three “info” displays: the clock times for White and Black, the last
few moves played, and the computer’s analysis of the position (see
example).
The moves shown are the “main line”, i.e. the continuation that ChessGenius rates as
strongest for both sides. A press on switches between this display and the name of the
opening with which the game started (available in English and German only).
“Score” gives the evaluation of the position. Here the computer thinks it has an advantage
worth nearly half a pawn. The number on the right is the “search depth”: when it
calculated the main line, ChessGenius was looking 8 “ply” ahead (one ply is a single move
by White or Black).
Further examples of items in the info display:
•Score: –1.85 The computer has a disadvantage nearly equivalent to 2
pawns.
•Score: Mate 7 The computer can force checkmate in 7 more moves.
•Score: –Mate 4 The opponent can force checkmate in 4 more moves.
•Book 6.e3 The current position and the move 6.e3 are in the computer’s
“openings book” (see Section 9).

4. Start a new game: Your choices
You can start a new game at any time except during some operations listed in Sections 8-
9. A press on the “NEW GAME”button ()gives you 4 choices:
•The user plays “up the board” with White..
•The user plays “up the board” with Black.
•Both White and Black are played by the user(s). See Section 8: “2
Players/Analys”.
•The Computer enters “Set up” mode. See Section 11: “Setting up a position”.
To make your selection, use the / buttons and confirm with GREEN.
5. System help messages
At any time, for guidance on what to do next, you may press the “?” button to see a
scrolling explanatory message.
In game mode, the button shows you all pieces which can move in the current position.
When you select one specific piece and press this button, the computer shows you the
squares that the piece can move to in the given position.
6. Switch OFF/ON
The “POWER”button on the control panel places the computer in “standby” mode or
switches it “on” again. In “standby” mode, ChessGenius retains the game in its memory,
and after switching on you can resume play from the same point.
Note: Except while calculating a move, ChessGenius will enter “standby” mode
automatically if there has been no press on a square or button in the last 10 minutes.
If you don't want to use the computer for a lengthy period or if you want to transport it,
you can disconnect the power supply completely with the ON/OFF switch (at the back of
the computer beneath row 8 of the chessboard). Place the computer in standby mode
beforehand, so that your settings and your last game are saved.

7. Functions of the control buttons
Note: The RED and GREEN buttons have various uses. Their functions in the current
situation are indicated in the bottom left and right corners of the screen.
RED Reverts to the previous LCD display. In normal playing mode, cycles
round three “info” displays:
•clock times
•the last few moves played
•analysis of the position.
Confirms a position that the user has been “setting up”.
Cancels a change of “level”.
The button’s current function is indicated at the bottom left of the
LCD; “i” denotes “info”.
GREEN Accesses the main menu.
•Selects an item from the menu or other list.
•Confirms a change of “level”.
Current function is indicated at the bottom right of the LCD.
Starts a new game.
? Displays “help” text, stating what the user may do next.
At any time, if unsure what to do next, you may press this button to
see a “scrolling” explanatory message.
Regulates the “backlight” of the LCD.
The backlighting of the LCD can be adjusted by repeated presses on
this button. (Low brightness means increased battery life.)
If powered by fresh batteries, the display is automatically “dimmed”
after 5 minutes in which the user has not pressed the membrane
chessboard or a control button. With low batteries, the dimming
occurs after one minute. The lighting is restored by the next press.
Retracts a move, or:
•Decreases a parameter number.
•Alters a parameter setting.
•In “Set up” mode: cycles through the various piece types.
Can be held down to “auto-repeat”.
Replays a move that was retracted, or:
•Increases a parameter number.
•Alters a parameter setting.

Navigates the screen, stepping down through a list of items; allows
“scrolling” to bring further items into view.
•In “analysis” display: switches between main continuation and
opening name.
•In “Set up” mode: switches between white and black pieces.
Switches the computer on, or places it in “standby” mode.
In “standby” mode, ChessGenius retains the current game and
parameters (e.g. the “level”) in its memory, and after switching on
again you can resume play from the same point.
Except while calculating a move, ChessGenius will switch off
automatically if there has been no press on a square or button in the
last 10 minutes.
If you don't want to use the computer for a lengthy period or if you
want to transport it, you can disconnect the power supply
completely with the ON/OFF switch (at the back of the computer
beneath row 8 of the chessboard). Place the computer in standby
mode beforehand, so that your settings and your last game are
saved.
RESET Located in a recess on the underside of the unit. Activated by
inserting a thin object into the opening. If this is done while the RED
button is held down, the settings are restored to the state in which
you first acquired the computer.
ON/OFF The switch located next to the input for the power adaptor, under
row 8 of the chessboard. Disconnects the computer from its power
source. Use this function if you travel (in this way you avoid
switching on accidentally), or if you are storing the computer for a
lengthy period of time.

8. Special functions –the main menu
At any time during play when “MENU”is shown at the bottom right of the screen, a press
on the GREEN button displays a menu of commands for activating the computer’s special
functions.
By repeatedly pressing or , you can inspect the full list of functions and highlight each
one in turn. To activate a function, highlight it and press GREEN. To return from the menu
to the chessboard display, press RED.
Note: Items displayed with grey wording are not currently enabled.
Hint –get a hint
Asks the computer to suggest a move for you. You may accept by playing the move, or
reject the suggestion by playing a different one. (To cancel the “hint” display, press RED or
GREEN.) Note that the quality of suggestions is dependent on the playing level you have
set.
Move now –force the computer to move
If it is your turn, this command makes ChessGenius move next and “swap sides” with you.
If ChessGenius is calculating its own move, the command makes it cut short its
calculations and play immediately.
Back/Forward all –jump to start or end of the game
Takes you back to the starting position, allowing you to replay the moves of the game
with the button. If you are at the start already, this command takes you to the end
position.
Next best –get an alternative move
Makes the computer retract its last move and play the one that it rates as next best. (The
command may then be repeated if desired.)
2 Players/Analys –the computer as referee
Allows you to make moves for both White and Black. The computer will merely give its
analysis of the position. To return to human-versus-computer play, select this same item
again; alternatively select “Move now” (or start a normal game with the button).
Play level –choose your playing strengh
Enables you to inspect and alter the computer’s level of playing strength. See Section 10.
Options –further settings
Displays a list of parameters (e.g. which side plays “up the board”, sound volume, design of
pieces for the LCD…) which can be selected and regulated with the arrow buttons. See
Section 9.
New game –restart
Enables you to start a new game. Offers you games against the computer with choice of
colour. Also gives access to “2 players” or “Set up” mode, for your training or analysis.
Set up position –customized chess positions
Places the computer in “Set up” mode, allowing you to construct a special position on the
chessboard. See Section 11.

Save/Load –save and replay your games
Enables you to save up to 12 games to the computer’s memory, or to retrieve a game that
was saved previously. See Section 12.
