EXCALIBUR 375-2 LCD Chess & Checkers - Manual (Page 6)

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
right), 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 chess-
board 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.
Individual Moves
Turn on the HELP feature under
OPTIONS (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 diagonals
on which it stands, but cannot pass over
another piece.
2. The Rook can move to any square
along the same row or column on which
it stands, but cannot pass over another
piece. See also Castling (below.)
3. The Bishop can move to any square
along the diagonals on which it stands,
but cannot pass over another 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 diagonally (forward) one square.
See also en passant (page 12.)
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:
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 the 2nd key, then the SETUP key.
Use the DIRECTION button to move
the black shape over a piece. Press
MOVE to remove the piece. Press
CLEAR to continue the game.
Adding or Changing a Piece
Press 2nd then the SETUP key. Now
press SETUP repeatedly to select the cor-
rect piece. Use the DIRECTION button
to move it to a square. Then press MOVE
to register the piece. 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 2nd then OPTIONS until
CLrBr (clear board) is displayed. Now
press the SETUP key. You’ll see that
your display board is automatically
cleared, except for a White king.
Use the DIRECTION button to move
the White king to the correct square and
press MOVE. Continue by placing the
Black king on it’s square. (You can’t
leave the SETUP mode until both the
White and Black king are placed.) Black
pawns will be the next piece to place, but
you may press SETUP repeatedly to
select the piece type you want to place on
the board. To change the piece’s color,
use the ‰ / „ key. Don’t forget to press
MOVE to register 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.
Make sure that LCD Chess knows which

dard antidote for an attack on the wing. The
next stage starts with 16. h4. Portisch
announces his intention to attack on the king-
side. He refrains from castling his own king
into safety because he knows it’s safe enough

him to break through with his attack. When

unstoppable attack with 18. Bxh6 and then

hope of defense. In the final position, Black

setup mode, you may change the color of
the side to move by pressing ‰ / „.
Operational Hint
If you missed where the computer
moved, simply press UNDO and then
MOVE. This will not affect being able to
rate your game.
