• 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 rechargeable batteries of 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.

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 response to an opponent’s move.

Problem Setup — lets you set up special chess problems so you can practice solving problems published in newspapers, chess literature, or history books.

We recommend that you read these instructions thoroughly before you use your computer.

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 number (1 through 8), and also consists of 8 squares alternately colored green and white.

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.

(rook) — can move any number of squares vertically 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 vertically, then moves 1 additional square at a right angle from its first move. At the end 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.

-#

¨

(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) — can move only 1 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 forward 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.

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.

5

6

Here's an example of an en passant capture.

The white pawn advances from E4 to E5. The black pawn is still in its original position (D7).

%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.

The black pawn advances from D7 to D5.

The white pawn advances to D6 (one square behind 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.

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 adjacent 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 situation by hiding it behind a fortified position or moving it out of immediate danger of attack. You can castle if:

• 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.

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.

Questions and Answers

What does the Clear/On button do?
It turns the computer on.
How can I turn off the computer?
Press the RATING/OFF button.
What should I do if the computer doesn't turn off when I press RATING/OFF?
If the computer is thinking, it might not turn off when you press RATING/OFF. If this happens, press OPTIONS/MOVE.
How can I reset the computer?
Insert a pointed object, such as a straightened paper clip, into the RESET hole on the front of the computer.
What is the purpose of castling?
Castling protects the king from a potential check or checkmate situation by hiding it behind a fortified position or moving it out of immediate danger of attack.
When am I allowed to castle?
Castling is allowed if: The king has not moved from its 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.
What is the difference between a king's side castle and a queen's side castle?
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.
How does the knight move?
The knight moves in an L-shaped pattern. It moves 2 squares horizontally or vertically, then moves 1 additional square at a right angle from its first move. At the end 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.)
