Congratulations on your purchase of Einstein LCD Chess Wizard. Now, the challenging game of Chess can travel with you anywhere. Einstein
LCD Chess Wizard offers varying levels of challenging computer opponents,
has simple, intuitive controls and is an expert chess teacher!
Albert Einstein is probably best known for his famous formula, E=mc2, but
this German-born theoretical physicist made unparalleled contributions to
modern scientific thought. In the field of physics, he introduced his special the-
ory and general theory of relativity and, in 1921, his work on the photoelectric
effect won him the Nobel Prize in Physics.
Einstein enjoyed playing the violin and for much of his life, greatly enjoyed
the game of chess. He routinely asked children he met if they liked music or if
they could play chess. He would then teach them the basics of the game, and
would play that child every time that they met.

Install the Batteries
Using a small Phillips screwdriver,
remove the screw from the battery-com-
partment panel on the back of LCD
Chess. Install two fresh, alkaline AAA
batteries, making sure to follow the dia-
gram in each battery slot so that the
polar-
ity (+ or -) of the batteries is correct.
Replace the battery compartment panel.
When replacing the screw, secure it gen-
tly, do not force or over-tighten it.
Play a Game Right Away
After you have installed the batteries, the
display will show the chess board with all
the pieces on their starting squares. The
LCD will also show PLAY. If it does not
display PLAY, press RESET using a
thin pointed object.
Unless you instruct it otherwise, LCD
Chess gives you the White pieces—the
ones at the bottom of the board. White
always moves first. You’re ready to play!
The way you select and make your move
is very simple.
• Press the NEXT PIECE or PREVI-
OUS PIECE key to choose the piece
you want to move.
• The first move for that piece will flash.
If you wish to select a different move for
that piece, press the NEXT MOVE or
PREVIOUS MOVE key.
(If you want to make a capture, it will be
quicker to use the PREVIOUS MOVE
key instead of the NEXT MOVE key).
• Press the GO key to enter your select-
ed move into the computer.
After you make your move, LCD Chess
will reply with its move automatically.
You’ll see the piece flash on its from
square and move to its to square. You're
already playing a game! Enjoy the con-
test.
Putting a game “on hold”
Any time it's your move and you wish to
stop playing for a while, just press the
ON/OFF key. LCD Chess will switch off
and go into a sleep mode. It will remem-
ber the last position, including the
elapsed time, as long as you do not inter-
rupt the power supply-for example, by
removing the batteries. To resume play,
just press the ON/OFF key.
NOTE: If it is not "thinking," LCD Chess
will automatically turn off after a period
of time, saving your game position. Use
the ON/OFF key to resume the game.

Piece Training
There are five special mini-games and
three mate training positions. The most
famous and successful chess teachers in
the world take their beginning students
from the simple to the complex by having
them play "mini-games" of chess that
concentrate on just one or more types of
pieces. Even advanced players practice
these basics, just as a concert pianist con-
tinues to practice the scales so that they
remain second nature. Like any great
trainer, LCD Chess will play you these
special practice games.
First make sure you are at the start of a
game. Now press TRAIN button, then
repeatedly press the + key. The mini-
games always include the king and pawns
for both sides. In fact, one mini-game
contains just this material (see figure on
left).
The other four mini-games use kings and
pawns, but add a different single piece to
the exercise-knight, bishop, rook, and
then queen.
Start with the basic king and pawns mini-
game.
Make your first move. Your object, as in
regular chess, is to checkmate the king.
Normally, this means both sides will try
to force a pawn through to the other side
of the board safely to promote it to a
queen. You'll learn lots of principles,
tricks, and traps in this training mode that
will win you many full-fledged chess
games!
Checkmate Training
The main objective in the game of Chess
is to checkmate your opponents king.
LCD Chess, has three special positions
that are shown after the five piece train-
ing mini games. The Black king will be in
the center of the board in those positions.
Select one of those positions to practice
and improve your technique to check-
mate your opponent’s king.

Using Setup Mode
At any time during a game when it is your
move, you may change the position on
the board by adding a piece, removing a
piece, or changing any of the pieces—for
example, from a queen to a knight.
Removing A Piece
Press SETUP then use the PREVIOUS
PIECE, NEXT PIECE, PREVIOUS
MOVE, NEXT MOVE buttons to move
the king cross over a piece. Press GO to
remove the piece. Press CLEAR to con-
tinue the game.
Adding or Changing a Piece
Press SETUP then use the PREVIOUS
PIECE, NEXT PIECE, PREVIOUS
MOVE, NEXT MOVE buttons to move
the king cross to the desired square. Now
press the + or - buttons for the desired
piece. Press GO to place that the piece on
the board. Press CLEAR to continue the
game.
Setting Up Special Positions
This is another terrific feature that allows
you to solve problems that you see in
magazines or newspapers, or that you
make up yourself. It also allows you to
enter game positions you want to play, or
that you want LCD Chess to look at, per-
haps using the Infinite Search level.
Normally, it is easier to start from an
empty board to set up such problems. So
first, press OPTIONS repeatedly until
CLbr (clear board) is displayed. Then
press the GO key. You’ll see that the dis-
play chessboard will have only the white
king, and PrOb is displayed.
Make sure that LCD Chess knows which
color is to move. You may change the
color of the side to move by pressing the
/button. The color icons and 
below PrOb will show the side to
move.
Use the PREVIOUS PIECE, NEXT
PIECE, PREVIOUS MOVE, NEXT
MOVE buttons to move the king to the
square the White king is on. Press GO to
place that the piece on the board.
Use the PREVIOUS PIECE, NEXT
PIECE, PREVIOUS MOVE, NEXT
MOVE buttons to move the king to the
square the Black king is on., and then
press the / button to change the
White king to a Black king. Press GO to
place that the piece on the board.
Next, pick out another piece in the prob-
lem or position you want to set up. Now
press +HINT button repeatedly to select
the correct piece. Use the PREVIOUS
PIECE, NEXT PIECE, PREVIOUS
MOVE, NEXT MOVE buttons to move
to the desired square. Press GO to place
that the piece on the board.
Follow this procedure until all the pieces
in the problem or position are completely
set up. Finally, press CLEAR to play or to
have LCD Chess analyze the position.
NOTE: You must place a White and
Black king on the board to exit SETUP
mode with the CLEAR key.
General Rules of Chess
1. The two players must alternate in mak-
ing one move at a time. The player with
the white pieces moves first to start the
game.
2. With the exception of castling (see
below), a move is the transfer of a piece
from one square to another square which
is vacant or occupied by an enemy piece.

Individual Moves
Turn on the HELP feature (see page 5.)
All legal moves for each selected piece
will be shown at one time. You will
quickly “learn by doing” the movements
of all pieces.
1. The Queen can move to any square
along the same row, column, or diaganols
on which it stands, but cannot pass over
an enemy piece.
2. The Rook can move to any square
along the same row or column on which
it stands, but cannot pass over an enemy
10
piece. See also Castling (below.)
3. The Bishop can move to any square
along the diaganols on which it stands,
but cannot pass over an enemy piece.
4. The Knight move is in the shape of an
“L”, moving two squares up or down, and
then one square over. Or it can be one
square up or down, and then two over.
5. The Pawn can move one square for-
ward. On it’s first move it may move two
squares forward. When capturing, it
moves diaganolly (forward) one square.
See also en passent (below.)
6. The King can move one square in any
direction, as long as it is not attacked by
an enemy piece. See also Castling(below)
Special Moves
1. Castling is a move of both the King
and either Rook which counts as a single
move (of the King) and is executed as
diagrammed below:
Castling cannot occur if:
a) the King has already been moved.
b) the Rook has already been moved.
c) there is any piece between the King
and the Rook.
d) 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.
2. A Pawn may make an en passent cap-
ture if it is a reply move to a double pawn
move, and it is a Pawn which is side-by-
side with the Pawn which made the dou-
ble pawn move. The capture of a white
Pawn is diagrammed on right:
3. No piece, except the Knight 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 into a position
whereby he can attack the King, the King
is in “Check”. His opponent must either
a) move the King
b) block the path of the attacking piece
with another piece, or
c) capture 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”.
7. The game is over when the king of the
player whose turn it is to move is not in
check and the player cannot make any
legal moves. This is known as “Stalemate”
and is considered a drawn game.

Battery Information
• Your LCD Chess uses 2 “AAA” batteries.
• Do not mix old and new batteries.
• Do not mix alkaline & standard or
rechargeable batteries.
• Install batteries so that the polarity
(+ and -) matches the diagrams in the battery
compartment.
• Use only batteries of the same type and
equivalency.
• Remove exhausted batteries from the unit.
• Do not short circuit battery terminals.
Special Care
• Avoid rough handling such as bumping or
dropping.
• Avoid moisture and extreme temperatures.
For best results, use between the temperatures
of 39ºF and 100ºF (4ºC and 38ºC).
• Clean using only a slightly damp cloth.
Do not use cleaners with chemical agents.
Excalibur Electronics reserves the right to
make technical changes without notice in the
interest of progress.
Computers can sometimes "lock
up" due to static discharge or
other electrical disturbances. If
this should happen, use a slim,
pointed object to press the but-
ton marked “RESET.”
3. A Pawn can be promoted if it advances
all the way to the far side of the board. It
is immediately promoted, as part of the
same move, into a Queen, Rook, Bishop,
or Knight, whichever its owner chooses.
Since a Queen is the most powerful piece,
it is nearly always chosen as the promo-
tion piece. Through the promotion
process, there may be more than one
Queen on the board at the same time.
Some Tips on Chess
1. Castle your King into safety as soon as
possible.
2. If you control the center squares you
will achieve an advantage. To do this
move your center Pawns and develop
your Bishops and Knights early in the
game.
3. Take advantage of capture situations,
particulary if you will gain material.
