Install the Batteries
Using a small Phillips screwdriver,
remove the battery-compartment panel
screw on the back of LCD Chess. Then
remove the panel by pulling gently from
the top. Install three fresh, alkaline AAA
batteries, making sure to follow the diagram in each battery slot so that the polarity (+ or -) of the batteries is correct.
Replace the battery compartment panel.
When replacing the screw, secure it gently, do not force or over-tighten it.
Play a Game Right Away

and continue the game. When a stalemate
is reached, the display will read StALE.

appears, it indicates you are in two
human player mode. And lastly when an

Setting Up Special Positions
If you attempt to use the HINT, SETUP,

This is another terrific feature that allows
you to solve problems that you see in

Black king on it’s square. (You can’t
leave the SETUP mode until both the
White and Black king are placed.)
Repeatedly press the SETUP key to
select the piece type you want to place on

Computers can sometimes "lock

other electrical disturbances. If
this should happen, use a slim,
pointed object to press the button marked “RESET.”
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.
Make sure that LCD Chess knows which
color is to move. When you first enter
setup mode, you may change the color of
the side to move by pressing q / n.
General Rules of Chess
1. The two players must alternate in making one move at a time. The player with
the white pieces moves first to start the
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.
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
Individual Moves
Turn on the HELP feature (see page 4.)
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
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 forward. 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 capture if it is a reply move to a double pawn
move, and it is a Pawn which is side-byside with the Pawn which made the double pawn move. The capture of a white
Pawn is diagrammed below:
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 promotion piece. Through the promotion
process, there may be more than one
Queen on the board at the same time.
