ongratulations on your purchase of

Excalibur Electronics’ Alexandra the

Great chess computer! You’ve pur-

chased both your own personal chess

trainer and a partner who’s always

ready for a game—and who can improve as you

do! Talking and sound effects add another dimen-

sion to your Alexandra computer for increased

enjoyment and play value.

The legendary King Arthur brandished a

magic sword, Excalibur, from which we take

our company name. With this unique weapon

in his hands, he could not be vanquished.

Although Excalibur Electronics

can’t claim the magical secrets of

Merlin, King Arthur’s court wiz-

ard, sometimes our patented tech-

nology may make it seem as if we

could. The Alexandra the Great

Talking Chess Computer is anoth-

er unmatched innovation of

Excalibur Electronics.

Finding the Pieces

Turn your chess computer over carefully with its chessboard face-

down. Find the door marked “PIECE COMPARTMENT DOOR.”

Open it and remove the chess pieces. Replace the door and set the

pieces aside for now.

Battery Installation

With the chess computer facedown, find the door marked “BAT-

TERY DOOR.” Open it and insert three (3) fresh, alkaline AA bat-

teries in the battery holder. Note the arrangement of the batteries

called for by the diagram in the holder. Make sure that the positive

tip of each battery matches up with the + sign in the battery compart-

ment so that polarity will be correct.

When the batteries are properly installed, Alexandra the Great auto-

matically turns on and starts talking, letting you know she's ready for

action. If Alexandra does not start talking, use a thin pointed object

and press the ACL button. Replace the battery compartment panel,

and turn the computer over.

Play a Game Right Away

After you have installed the batteries, the display will show ENG-

LISH? asking you if you want Alexandra to speak in English. If you

do, press the YES key. If you want her to speak French or German,

press the NO key until your desired language is shown and then

press the YES key. Place the plastic chess pieces on their start ing

squares (see page 20). The display will show

01CHESS. This indi-

cates you are at the first move of the game and ready to play chess.

ENGLISH

piece gently on its new square. (Some players like to push the

squares with their forefinger while holding the piece in the rest of the

fingers of the same hand.)

Moving Alexandra’s Piece

You'll notice that Alexandra almost immediately displays her

response to your move. Alexandra decides on her own move, of

course, and lets you know what it is on the display below the LCD

board. For example, if you play 1. E2-E4, she may respond E7-E5.

But you need to move the piece on the board for her. Follow the

same two-step procedure you did while registering your own

move—gently pushing on the FROM and TO squares. You're

already playing a game! Enjoy the contest.

Putting a game “on hold”

Any time it's your move and you wish to stop playing for a while,

just press the OFF/SAVE key. Alexandra will switch off and go into

a sleep mode. She will remember the last position, including the

elapsed time, as long as you do not interrupt the power supply—for

example, by removing the batteries. To resume play, just press the

ON/CLEAR key.

Unless you instruct her otherwise, Alexandra gives you the White

pieces—the ones at the bottom of the board, as pictured above.

White always moves first. You’re ready to play!

Making Your Move

Besides deciding on a good move, you have to move the piece in a

way that Alexandra will

recognize what's been

played. Think of commu-

nicating your move as a

two-step process—

registering the FROM

square and then register-

ing the TO square.

Lift the piece or pawn

you want to move. Press

the edge of the piece's

base down gently on the

center of its FROM

square. Alexandra will

say and display the coordinates of the FROM square—for example

“E2.” Then press the edge of the piece down gently on the square

you want to move it to—for example, “E4.” Alexandra will say the

TO square, confirming that she has registered your move. Place the

After pressing a FROM square, press the FROM square

again to select a different FROM square.

STALE.

Game-ending Messages

Alexandra will announce

mate in two (

Screen Symbols

When a “+” appears on the

screen, it is a reminder that you

are in check. When an “O”

appears on the screen, the game

you are playing can be rated.

When an “=” appears, it indi-

cates you are in two human

player mode. And lastly, when

an “!” appears on the screen,

you are being warned that one

of your pieces is threatened

with capture. (This is similar to

the friendly “en garde” warning

sometimes used by human

players when they are attacking

an opponent’s queen.)

Special Situations

Starting Play

with the Black Pieces

When you want to play the

Black pieces (to let Alexandra

move first), press the

MOVE

key before you make your first

move as White. Set the Black

pieces up at your end.

Castling

Remember, you must always

move the king first when

castling! First press your king

down on its

FROM square (if

castling, E1). Then move and

press your king down on its

square (if castling kingside,

G1). Alexandra recognizes

castling maneuvers after the

king is moved two squares. She

then reminds you to complete

castling by moving the rook.

Move the rook in the routine

GAME before the game is

completed. If the score is

greater than 9.0, you can claim

a victory with the

NEW

GAME

key.

CLRBR: Use this option to

clear the chessboard for easier

problem setup. Pressing the

SETUP key will enter setup

mode with the chess board

cleared of all pieces. You must

place a White king and a Black

king on the board to exit setup

mode.

VOICE: Use this option to

change the language Alexandra

speaks. Also use it to turn most

of the speech off. Some warn-

ings such as “Check” and “Are

You sure?” will still be heard

however. 1—English, 2—

French, 3—German, and 4—

none.

SNDEF: Use this option to

turn the sound effects off.

ANNC: Use this option to

turn the move announcements

off.

one of your pieces is under

attack. The threat warning “!”

will be enabled when

COACH

option is on.

SOUND: Use this option to

turn the sound on or off.

SLEEP: Adjust the automat-

ic shut off time with this option.

Setting it to “0” will disable

auto shut-off altogether.

Special Displays

Draw Messages

During the game, Alexandra

will display the word “

position occurs, or if there has

been no pawn moved and no

exchanges for 50 moves. When

either of these situations takes

place, the rules of chess state

ENGLISH

manner, pushing on its FROM

and TO squares normally.

Promoting Pawns

When your pawn reaches the

other end of the board, Alex-

andra will automatically pro-

mote the pawn to a queen, since

this is the best choice in nearly

every case. In the unlikely

event you want to promote your

pawn to a piece other than a

queen, takeback Alexandra’s

move, next use Alexandra's

SET UP feature to make the

piece change, and then press

MOVE.

When Alexandra pushes a

pawn to your back row, it will

always promote to a queen.

Remember to replace the pawn

with the proper piece on the

board after either side promotes

a pawn.

En Passant—

taking a pawn in passing

For an en passant capture,

press the

FROM and TO

squares of the capturing pawn.

The square of the pawn being

captured will then appear on

the display. This is to remind

you to remove the captured

pawn. You must press down on

the captured pawn before

removing it.

Taking Back a Capture

After you take back a cap-

ture, the square of the captured

piece will then appear on the

display. This is to remind you

to put back the captured piece.

You must press on the square of

the captured piece.

Levels of Play

Alexandra offers six level

types. Two types (PLY and

MATE) are for analysis. The

other four level types are for

play.

always include the king and

pawns for both sides. In fact,

one mini-game contains just

this material (press

PAWN).

The other four mini-games use

kings and pawns, but add a dif-

ferent single piece to the exer-

cise—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!

want—or even an opening you

invent—to practice. Press

moves for both sides until the

opening position you want to

practice is reached. Now press

MULTI-MOVE again. Press

CLEAR to play against the

computer in this position.

Piece Training

There are five special mini-

games. The most famous and

successful chess teachers in the

world take their beginning stu-

dents 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 contin-

ues to practice the scales so that

they remain second nature.

Like any great trainer,

Alexandra will play you these

special practice games.

First make sure you are at the

start of a game by pressing

NEW GAME. Now press

OPTIONS until “TRAIN” is

displayed. Then press the key

(queen, bishop, knight, rook, or

pawn) of the mini-game you

want to try. The mini-games

you wish to play against.

When an “O” appears on the

display, the game you are play-

ing can be rated. Since the

game you are playing is rated,

you cannot ask for a

HINT, nor

TAKEBACK a bad move, nor

use

SETUP to improve your

position. You also cannot use

the

NEW GAME key to start

over during a rated game.

These conditions allow you to

experience what it is like to

play a game against an oppo-

nent in a rated tournament. In

rated tournaments a chess clock

is always used, so that you play

your moves within agreed upon

time limits. Alexandra has a

built-in chess clock.

If you attempt to use the

HINT,

SETUP, TAKEBACK

, or

NEW GAME keys during your

rated game, Alexandra will ask

“Are you sure” and say what

result (draw, win, or loss) will

be scored if you press the YES

key.

During a rated game, if you are

winning by 9.0 or more points

and want Alexandra to resign,

press

NEW GAME. Alexandra

will say “Are you sure I lose?”

Alexandra will then wait for

you to press YES.

Using

Verify Mode

At any time during a game

when it is your move, pressing

VERIFY will display the posi-

tion of the Black queen. The

letter B will be shown if a piece

is black and a W will be shown

for the white pieces. Pressing

VERIFY a second time to

check the position’s of White’s

queen.

To verify the positions of the

other pieces on the board, sim-

ply press the key labeled with

the desired piece symbol above

it. If there are no pieces of the

selected type on the board, the

display will show “

NONE.” To

exit this verification mode,

press the

ON/CLEAR key.

Using

Setup Mode

At any time during a game

when it’s your move, you may

change the position on the

board by adding a piece,

removing a piece, or changing

any of the pieces—for exam-

ple, from a queen to a knight.

Removing A Piece

Press the SETUP key. Then on

the large sensory board, press

the square the piece is on until

the square on your display is

empty. Press CLEAR to contin-

ue the game.

Adding or Changing a

Piece

Press the SETUP key. Next

press the key that indicates the

type of piece you want to place

on the board. Then on the large

sensory board, press the square

on the sensory board until the

piece appears as the correct

color on your display. Press

CLEAR to continue the game.

Setting Up Special

Positions

This is another terrific feature

that allows you to solve prob-

lems 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

Alexandra to look at, perhaps

using the Infinite Search level.

Normally, it is easier to start

from an empty board to set up

such problems. So first, press

the

OPTIONS key repeatedly

until “

CLRBR” (clear board) is

displayed. Now press the

SETUP key. You’ll see that the

display will show “

NONE,”

indicating no kings.

On the large sensory board,

press the square the White king

is on. Next press the square the

Black king is on once to place a

ENGLISH

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 attack-

ing piece with another piece;

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

Use the WHERE key (see page

3) and all legal moves for each

selected piece will be shown

one at a time. You will quickly

“learn by doing” the move-

ments of all pieces.

1. The queen can move to any

square along the same row, col-

umn, or diagonals 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 (on

right.)

3. The bishop can move to any

square along the diagonals 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

White king there, and then

again to change the White king

The Starting Position

General Rules of

Chess

1. The two players must alter-

nate in making 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

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 its first

move it may move two squares

forward. When capturing, it

moves diagonally (forward)

one square. See also en passant

(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

passant capture if it is a

reply move to a double

pawn move, and it is a pawn

which is side-by-side with

the pawn that made the dou-

ble pawn move. The capture

of a White pawn is dia-

grammed below:

3. A pawn can be promoted

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.

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 promo-

tion process, there may be

more than one queen on the

board at the same time.
