PLAYING A GAME
a) Please make sure the unit is at least 16 cm (6.3 inch) away from a wall or obstruction, because
the robotic arm needs space to retract backwards. Then, setup the chess pieces: White pieces on
rank 1 and 2, Black pieces on rank 7 and 8.

b) Connect the unit to the mains and push the power switch located on the backside of the unit to
ON.
c) Press NEW GAME. You will hear 3 beeps and the LCD will show " – – – – ".
d) You can now make your opening move for White. Gently push down the chess piece you wish to
move. Once you hear a beep you can proceed to place that piece on to the square you wish to
move to. Please apply some pressure again until you hear a beeping sound. The beeping sound
means that the computer has registered your move. At the same time your move will be shown
on the display.
e) The unit will immediately start computing its counter move and execute it automatically with its
robotic arm. Please be patient and wait for the computer to complete its move before you continue
the game.

5
Notes:
When your computer is calculating (the Black/White colour indicator is blinking) only the GO
key will function. When pressed, it will interrupt the computer’s calculation and the current
move that is being analyzed will be played at once.
When you capture a piece, simply remove that piece without depressing it and make your move
as described above. Please place the removed piece on the side as described below under
“CAPTURED PIECES / SETTING UP BOARD”.
If the arm should ever get stuck, please unplug and then re-plug the unit. The arm will drop the
chess piece, if any, and the arm will move to its original position. Never move the arm by force.
CAPTURED PIECES / SETTING UP BOARD: USING SIDE PANELS FOR CHESS
PIECES
Chess pieces that have been captured or that are placed on the side panel when setting up board (see
chapter 12) are always set in the same manner: the chess pieces that play from the bottom rank
(normally white) are placed on the right hand side of the chess player and the chess pieces that are
playing from the top rank (normally black) on the left hand side of the chess player. Please place the
pieces according to the symbols on the panels and place them in top to bottom order.
Example 1:you are playing either white (or black) from the bottom ranks:Your white (or black)
chess pieces will be placed on your right hand side when captured. When you capture a black chess
piece from your opponent, please place it on the left side of the board (= the opponent’s right side).
Example 2: you are playing black from the TOP ranks (Press GO to force the unit to make the
move for white): Your black chess piece will be placed on your LEFT hand side when captured.
When you capture a white chess piece, please place it on the RIGHT side of the board (= the
opponent’s left side).

6
NOTE:
It is important to set the captured pieces in TOP TO BOTTOM order on the correct side as described
above, otherwise you may run the risk that the chess computer will place one chess piece on top of
another. This may damage the unit and is excluded from the warranty. Should this ever happen and
the arm get stuck please unplug and re-plug the unit. The arm will then drop the chess piece, if any,
and move to its original position.
MEMORY
The unit will retain the last board position, providing it is connected to the mains. If you are using
SET UP or VERIFY mode the computer will remain in that mode when you switch it off. To
continue the game or start a new game press the GO key first to exit these modes.
2. IMPOSSIBLE AND ILLEGAL MOVES
The chess computer was programmed in accordance with the International Chess Rules and will
display “ERROR” if you try to make an illegal move. Retract your move without pressing on any
square. You can now make another legal move.
3. CAPTURING A PIECE
Remove the opponent’s chess piece and place it on the side of the board as described above. Now
make your move as usual. If the computer captures a piece it will execute its move automatically. The
LCD will display the symbol "x" and in cases of "en passant" pawn captures this will be indicated by
the symbol "EP".
4. GAME FEATURES
a) Castlings
When Castling first press the 2 squares for the King and then move the Rook by applying pressure
on the appropriate squares (the computer executes Castlings itself). Please note that you may not
castle while your King is in check, nor may you castle through check. The chess computer accepts
and executes Castlings in set up board positions.
b) En Passante Captures
To make this move you only have to enter the "from" and "to" squares as in a normal move and
remove the captured piece by gently pressing that square. The computer executes En Passant
automatically. The LDC will display the en passant capture as "EP".
c) Pawn Promotions / Underpromotions
When (under-) promoting the LCD will display “Pro?”. Choose the piece you wish to (under-)
promote by pressing the respective Piece Symbol Key on the board. Please note that if a computer
pawn reaches the opposite side, the computer will only indicate on the LCD display into which piece
the pawn will be promoted/underpromoted.

7
d) Stalemate /Draw
AStalemate condition is indicated on the LCD display. Draw to insufficient material will be
announced by the word "dr Ins" on the LCD display.
e) Check and Checkmate
If the computer puts you in check "+" will be displayed on the LCD. If you put the computer in check
this will not be specifically displayed. In a checkmate situation "MATE “ together with a double
cross sign will be shown on the LCD display indicating the end of the game.

"Ver – –" will be displayed.
OR
Press each piece on its square and check the information on the LCD display:
The piece symbol, Black/White colour symbol and the square position is shown. If the square
should be empty, you only see the square position but not the piece symbol on display.
To end this mode at any time simply press the GO key. You can now enter your next move or
call-off a move for the computer.
12. SETTING UP A POSITION (Ver/Set Key = Verify/Set Up Key)
This mode is designed to enable you to set up board positions to solve chess problems or to set
handicaps by removing or entering a piece, as well as changing the positions of pieces. In SET UP
mode the computer’s legality check is disabled and you can enter, remove or change positions of any
piece.

14
However you cannot set up incorrect positions, e.g. play without both Kings or with more than one
King for each colour....etc. If the position is illegal, the word "Error" comes on display. The computer
will accept and execute castlings, pawn promotions and en passant captures if you play from a set up
board position.
Note: All previously stored moves are deleted as soon as you enter the SET UP mode.
12.A Removing a Piece
If you wish to remove one or more pieces proceed as follows:
Press Ver / Set key twice, so that "Set" comes on display.
Remove the piece(s) one by one by applying gentle pressure on the square it stands on. The

function keys.
Only change colour or use the Piece Symbol Key if the piece varies from the preceding piece.
To end this mode press the GO key.
12.C. Moving a Piece to another Square
If you wish to change the position of one or more pieces whilst the game is in progress proceed as
follows:
Press the Ver/Set key twice, so that "Set" comes on display.
Move the piece(s) by pressing on the "from" and "to" square as in a normal move (the piece
symbol and square position is shown on the LCD display).
To end this mode press the GO key.
13. CLEARING THE ENTIRE BOARD (Clear Key)
If you want to set up a board position it is best to clear the entire chessboard first. Remove all pieces
from the board and set up your new position without pressing down on any square; then enter this
position as follows:
Press the Ver/Set key twice.
Press the CLEAR key to delete the computer’s memory (the LCD will display "Set").

15
Now enter your position piece by piece into the computer as described under section 12B.
To end this mode press the GO key.

display shows "Sound "to indicate that all acoustic signals are switched ON.
TROUBLE SHOOTING
CALIBRATION
In the event that the chess pieces are not placed in the centre position of the square and/or the 2Robot
is unable to pick up the pieces you may calibrate the unit. To calibrate the unit correctly you need to
fine-tune squares A8 (short reach of the arm) and square H1 (long reach of the arm).
NOTE:It is important that you calibrate both squares to achieve accuracy.
CALIBRATION OF SQUARE A8 (short reach of arm)
Place a chess piece on square A8.
Press the CLEAR key for approx. 5 seconds until you see P1:xx.yy_ (the display represents the
current numerical value for the calibration in position P1).
Press GO and wait for the computer to complete its move.
Check the position of the chess piece once the move is completed and compare it to the
schematic below. The actual squares on the chessboard B1 to H7 represent square A8. Proceed
as described in the example.

16
Example: If the chess piece is at the upper left corner of the square A8 (as depicted below), press the
square B7 on the chessboard with another chess piece until you hear a beep. The computer will now
know that the chess piece is standing in the upper left corner of square A8 and will automatically
adjust its calibration to move the chess piece more towards the centre in the next move (if the chess
piece is in the top right corner, press square H7 and so on). Press the GO key to double-check the
position. Repeat if necessary. Once you are satisfied that the chess piece is centred, proceed with the
calibration of square H1 (long reach of arm).

CALIBRATION OF SQUARE H1 (long reach of arm):
Place a chess piece on square H1.
Press the SOUND key and the display will toggle to P2:xx.yy_ (the display represents the
current numerical value for the calibration in position P2).
Press GO and wait for the computer to complete its move.
Check the position of the chess piece once the move is completed.
Check the position of the chess piece once the move is completed and compare it to the
schematic below. The squares A8 to G2 on your chess computer shall represent square H1.
Proceed as described in the example (same procedure as calibration of square A8).
Example: If the chess piece is at the upper right corner of the square H1 (as depicted above), press the
square G8 on the chessboard with another chess piece until you hear a beep. The computer will now
know that the chess piece is standing in the upper right corner of square H1 and will automatically
adjust its calibration to move the chess piece more towards the centre in the next move (if the chess
piece is standing on the lower left corner of square H1, press the actual chessboard square A2, and so
on). Press the GO key to double-check the position. Repeat if necessary. When you are satisfied the
chess piece is centred, please verify the calibration:

Rules of Chess
I. General Moves
1. The two players must alternate in making one move at a time. The player with the white pieces
moves first to start the game.
2. With the exception of castling (section II.1.), a move is the transfer of a piece from one square to
another square which is either vacant or occupied by an enemy piece.
3. No piece, except the Rook when castling and the Knight (section II.5) may cross a square
occupied by another piece.
4. A piece moved to a square occupied by an enemy piece captures it as part of the same move. The
captured piece must be immediately removed from the chessboard by the player making the
capture.
5. When one player moves a piece into a position whereby he can attack the King, the King is in
"Check" (announced on the LCD display) and must either
a) move the King,
b) block the path of the attacking piece with another piece,
c) or attack the attacking piece.
6. The game is over when there is no escape for the King from an attacking piece. This is known as
"Checkmate" (shown on the LCD display).
II. Individual Moves
1. KING
Except when castling, the King can move only one space to any adjoining square (including
diagonally) which cannot be attacked by an enemy piece. Castling is a move of both the King and
either Rook which counts as a single move (of the King) and is executed as follows:
a) The King is moved from its original square two squares toward either Rook on the same rank,
and
b) The Rook is moved to the opposite side of the King.
Castling cannot occur if:
a) the King has already been moved.
b) the Rook has already been moved.
c) the King's original square or the square which the King must cross or the one which it is to
occupy is attacked by an enemy piece.
d) there is any piece between the King and the Rook.
2. QUEEN
The Queen can move to any square along the same rank, file or diagonal on which it
stands (except as limited by Article I.3).
3. ROOK
The Rook can move to any square along the same rank or file on which it stands (except as limited
by Article I.3).

19
4. BISHOP
The Bishop can move to any square along the same diagonal on which it stands (except as limited by
Article 1.3).
5. KNIGHT
The Knight's move is in the shape of an "L", moving two squares horizontally vertically, and then
one square at 90° angle from the first move. These two moves can be reversed (one square and then
two) if desired.
6. PAWN
The Pawn can move either one or two squares forward on its first move, and then one square forward
at any time afterward. When capturing, it advances one square diagonally (forward). When a Pawn
reaches the last rank, it must be immediately exchanged for a Queen, Rook, Bishop, or a Knight of
the same colour as the Pawn, at the player's choice. This exchange is called a "promotion". A Pawn
can attack a square crossed by an enemy Pawn which has been advanced two squares in one move
from its original square as though the latter had been moved only one square. This capture may be
made only on the move immediately following such an advance and is called capturing "en passant".
III. HINTS & TIPS
Get a feel for the values of different pieces, which will be useful when making decisions on captures
and exchanges. In general, try to capture the more valuable pieces. Some important principles:
Castle your King into safety as soon as possible.
If you control the centre squares, this will give you the advantage. To do this, move your centre
pawns and develop your Bishops and Knights early in the game.
Take advantage of capture situations, particularly if you will gain material.
Concentrate – don't be caught off guard by your opponent!
