Your RadioShack Talking E-Chess computer is one
of the most versatile chess computers available.
Your computer can play chess at a rating of 1750.
More of the computer's features include:
Undo — lets you take back the previous move, to
help you improve your game.
Rule Enforcement — the computer prevents illegal
moves like a game referee, to help beginners learn
the rules.
Power Off Option — lets you turn off the computer
without interrupting the game in progress, so you
can continue playing later.
Help — shows you all legal moves you can make
during a game.
Move Suggestion — lets you ask the computer to
suggest your next move, teaching you the best re-
sponse to an opponent’s move.
Problem Setup — lets you set up special chess
problems so you can practice solving problems
published in newspapers, chessliterature, or history
books.
We recommend that you read these instructions
thoroughly before you use your computer.

Your computer requires three AA batteries (not sup-
plied) for power. For the best performance and
longest life, we recommend RadioShack alkaline
batteries. .#
."%#76+10".
• Use only fresh batteries
of the required size and
recommended type.
• Do not mix old and new
batteries, different types
of batteries (standard,
alkaline, or
rechargeable), or
rechargeablebatteriesof
different capacities.
• If you do not plan to use
the computer for a month
or more, remove the
batteries. Batteries can
leak chemicals that can
destroy electronic parts.

Following international chess notation, the chess
board is made up of 8 vertical rows called files, and
8 horizontal rows called ranks.
Each file (left to right) is designated by a letter of the
alphabet (A through H), and consists of 8 squares
alternately colored green and white.
Each rank (bottom to top) is designated by a num-
ber (1 through 8), and also consists of 8 squares al-
ternately colored green and white. ±

If you are replacing the
computer’s batteries, make
sure you turn off the

There are 16 white and 16 black pieces, 32 in all.
Each color has these pieces.
Each kind of piece moves in a different way. ±
«#/ ª(rook) — can move any number of
squaresvertically or horizontally, but it cannot move
through a square occupied by another piece.
¥#/ ¤(knight) — moves in an L-shaped
pattern. It moves 2 squares horizontally or vertical-
ly, then moves 1 additional square at a right angle
from its first move. At theend of its move, the knight
must land on a square of a different color than the
one it started from. The knight can move even if the
squares it moves through are occupied. (It is the
only piece that can “jump” another piece.)
¡#/ (bishop) — can move any number of squares
diagonally, but it cannot move through a square
occupied by another piece.
±"016'"±"
You can set up any pieces
you want in any legal order
withthecomputer’steaching
mode (see “Using Teaching
Modes” on Page 24).

-#/ ¨(queen) — can move any number of
squares vertically, horizontally, or diagonally. (The
queen's moves are a combination of the rook's and
bishop's moves.) The queen cannot move through a
square occupied by another piece.
£#/ ¢(king) — canmove only1 square vertically,
horizontally, or diagonally.
§#/ ¦(pawn) — can move only 1 (or 2) squares
directly forward, except when capturing another
piece. It captures a piece by moving diagonally for-
ward 1 square, except when capturing
en passant
.
(See “Capturing
En Passant
” on Page 6). When it
moves from its original position, it can move 1 or 2
squares forward. On subsequent moves, it can only
move 1 square.
A pawn can be promoted to a higher-ranking piece.
See “Promoting a Pawn” on Page 6.

The object of the game is to position your pieces so
your next move would capture the opponent's king,
and your opponent cannot move, protect the king,
or capture your piece. This is called checkmate.

6
Basic Chess Instructions
%JGEM
Check occurs when a
player's piece directly
threatens to capture the
opponent's king, but the
opponent can move the
king, or another piece, to
escape capture.
%CRVWTKPI
To capture a piece, you move your piece into the
square occupied by the piece you are capturing,
except when capturing an opponent's pawn
en passant
(see “Capturing
En Passant
”).
Remove the captured piece from the board.

A pawn can capture an opponent's pawn that has
just moved 2 squares from its original position.
Whenever your pawn is on your fifth rank, and your
opponent moves 2 spaces to the same rank adja-
cent to your pawn, then you can declare
en passant
and move to your sixth rank immediately behind the
pawn, then capture the pawn.
2TQOQVKPI"C"2CYP
If your pawn advances to the eighth rank, you can
promote it to a queen or another piece, even if the
queen or other piece is still on the board.
%CUVNKPI
Castling protects the
king from a potential
check or checkmate sit-
uation by hiding it be-
hind a fortified position
or moving it out of im-
mediate danger of
attack. You can castle
if:
Here's an example of an
en passant
capture.
The white pawn advanc-
es from E4 to E5. The
black pawn is still in its
original position (D7).
The black pawn advanc-
es from D7 to D5.
The white pawn advanc-
es to D6 (one square be-
hind the black pawn’s
position). The black pawn
is captured by the white
pawn, even though the
exact square it is on is not
occupied by the white pawn.

Basic OperationBasic Operation
• The king has not moved from his original
position.
• The rook that you want to move by castling has
not moved from its original position.
• The king is not placed in check on its current
square, the square to which it is going, or a
square it passes over.
• The squares between the king and the rook are
not occupied.
If a rook is on the same side of the board as the
king's square, this is called a
king's side castle
. If
the rook is on the same side of the board as the
queen's square, this is called a
queen's side castle
.
In castling, the king moves 2 squares in the
direction of either rook. The rook that is closest to
the king after the king has moved now moves to the
square right next to and on the other side of the
king. Castling counts as 1 move.

Playing chess against the computer is like playing
with a human opponent — you make your move,
and the computer responds with its move.
Making a move involves a FROM square and a TO
square. The FROM square is the current location of
the piece you plan to move; the TO square is where
you are moving the piece. ±ý°

Each level allows your computer to think for
different periods of time (tournament players call
these periods “time controls”). The longer your
computer thinks, the better moves it makes.
Generally the beginner levels are for beginners
while the remaining levels are for more
accomplished players. If you are a beginner, start
out with the beginner levels. The computer
purposely makes mistakes on these levels so you
can beat the computer and learn while you play.
The beginner levels also restrict the computer's
search depth, resulting in weaker play.
