3General information for playing on the computer
3.1 General
The LCD (liquid crystal display) records the current situation in the game, and indicates the
computer’s play. In some games (Chess, Four-in-a-Row, Nim, Northcote’s Game), you must
take some decisions before play starts.
The computer or the user may play first. To make the computer play first, press SWAP when
the game is ready to begin. The symbol □ or ■ (in the bottom left corner of the LCD) shows
which side (White or Black) plays next.
Notation: Observe that the playing board is marked with the co-ordinates of each individual
square, e.g. A1, G6 etc. These appear in the bottom line of the LCD when a move is being
announced or carried out. Example: In Chess, the computer is moving its pawn from e7 to e5.
The bottom line shows: E7E5
The co-ordinates E7 are shown “blinking”, and so is the pawn on that square of the LCD
board. Press the square on the playing board as you pick up the pawn. Then E5 “blinks”, and
the pawn is shown alternating between e7 and e5. Press the e5 square as you place the pawn
there.
When the computer is “thinking”, the bottom line of the LCD displays a rotating “hourglass”
symbol. It may also display the move that is being considered. To interrupt the computer and
make it play at once, press SWAP.
When it is your turn to play, a press on SWAP makes the computer play next –i.e. it swaps
sides with you.
An error (e.g. if you try to play an illegal move) is indicated by a buzz. If the co-ordinates are
cleared from the bottom line, start your move again.
The rules of the games are explained in the relevant chapters.

4.1 How to play chess
4.1.1 Chess pieces and basic positioning
Each of the players (“White” and “Black”) begins with 16 chessmen, or pieces, of his own
colour –namely one king, one queen, two rooks, two bishops, two knights and eight pawns.
KING:

QUEEN:

ROOK:

BISHOP:

KNIGHT:

PAWN:

The most important piece is the king, since the object of the game is to put your opponent’s king
in a position where it cannot avoid being captured.
At the start, the pieces are arranged like this:

A common mistake during set-up is mixing up the queen and king, so remember: “white
queen, white square” and “black queen, black square”.
4.1.2 The moves
White makes the first move, then the players move alternately. When it is his turn, a player must
move oneofhis pieces onto a square which is either vacant or occupied by an enemy piece. In the
latter case the enemy piece is “captured”, i.e. removed from the board. Each type of piece has its
characteristic way of moving.

The queen, rook and bishop cannot “jump across” another piece. For the sole exception (where
the rook “jumps over” the king), see “Castling” (§ 4.1.5. ).
(e) The knight’s move is like an “L-shape”: two squares horizontally or vertically, then one
square at right-angles. The knight is able to jump over other pieces (of either colour).

The pieces we have dealt with so far can capture enemy pieces by moving in their usual way. If
it is White’s turn to move in the position above, he may capture the black knight with his bishop
if he wishes.

When making a capture, the pawn moves one square diagonally forward..

The pawn is the weakest chess piece, but there are
some special points about the way it moves. From
its initial position in the second row, it can advance
by two squares. Whether to move it one or two
squares is up to the player. However, once it has
moved one square, a double move is no longer
possible.
The pawn captures in a different direction from
the way it moves, ie it captures diagonally one
square left or right. This also applies to the pawn
in its initial position. The diagram shows all
possible pawn moves and captures.
The white pawn can advance one or two squares, or it can capture the black knight. The black
pawn has already advanced one square from its initial position, and can therefore either
advance another square, or capture the white rook.
On reaching the far end of the board, a pawn is “promoted”, i.e. changed into a queen, rook, bishop
or knight. The player chooses the piece (normally a queen), and places it on the square to which
his pawn has just advanced. The pawn is removed from the board.
4.1.3 Check and checkmate: winning the game
If a player attacks one piece unnoticed by his opponent, that piece is lost. With the king,
however, the situation is different as it cannot be captured. It can be attacked like any other
piece, but the attack must be countered in the next move. As this attack is actually threatening
to check - with the king subsequently being in a check position –a less experienced player
will at that moment announce “check” to warn the opponent. Your computer will do just that,
but note that it is not really necessary.
There are basically three ways to counter a threatened check:
1) The king moves to a square not under threat;
2) The threatening piece is captured;
3) Another piece is positioned between the threatening piece and the king.

Europe Chess Champion - GB - Page 15



Here, all 3 situations are seen in a simple example.
White is in check, threatened by bishop d5 and
must make a move:
1) The king moves to h2 or g1 (not to g2 where it
would remain in check);
2) The rook captures the black bishop;
3) The rook moves to g2, thus eliminating the
check.
If a check cannot be countered by any of these
3 tactics, the king is checkmate,ie it couldn’t
possibly avoid being captured by the opponent’s
next move).
4.1.4 Stalemate –drawn game
If the player to move cannot make any legal move and his king is not incheck, the game is a draw.
This is called stalemate.


Here, it is Black’s move. His king is not in check, but
any move he makes with it would put it in check.
Black therefore has no legal moves and is
stalemated.
A draw may also be claimed if (a) exactly the same
position occurs three times, with the same player to
move; or (b) during a sequence of 50 moves for each
side, no capture is made and no pawn is advanced.
A draw may also come about simply by agreement
between the players.

Europe Chess Champion - GB - Page 16
4.1.5 Castling
This special move is made with the king and one of the rooks. The king moves two squares
towards the rook; the rook jumps over the king, landing on the square next to it.




White has castled king’s side; Black has castled queen’s side
Note that a player may not castle in the following circumstances:
If there is any piece (of either colour) in between the king and the rook.
If the king, or the rook with which the player wants to castle, has moved before.
If the king is at present in check.
If the square over which the king must pass (or, of course, the square where the king
would arrive) is under attack from an enemy piece.
4.1.6 En passant capture
This rule originates from the pawn’s double-step move. The diagram shows how it works:







By advancing only one square, the black pawn
would be captured by the white pawn. But is it
possible to negotiate the danger zone by using the
double-step move d7-d5? To prevent that from
happening, the en passant capture (French.: in
passing) was introduced:
If, after a double-step move, a pawn is positioned
next to an opponent’s pawn, this (latter) pawn is
allowed to capture the other pawn as if it had been
moved only one square.
This move is executed exactly as a capture move
after a single move: the white pawn moves from
c5 to d6 and removes the black pawn

Important: Capturing en passant is possible only as a direct reply to a double-step move.

Europe Chess Champion - GB - Page 17
4.1.7 Pawn promotion
It is very unusual for a pawn to reach the opposite side of the board (normally it is captured
on the way); however, on reaching the other side, it changes into a different piece of the same
colour. It cannot become a king nor remain a pawn, so you have a choice between becoming
a queen, rook, bishop or knight. Usually, the preferred promotion choice is the queen as it is
the strongest piece, but in rare cases a knight promotion is preferable, as the knight has access
to different squares.
Promotion is effected by removing the pawn and placing the new piece on the promotion
square. Replacing the pawn by a piece captured before is not required, ie a player can have
two queens or three knights on the board, even though it is not provided for in the original set-
up.
This rule contributes a great deal to the fascination of chess since, without promotion, a chess
game in its advanced phase could hardly be won with only the few pieces remaining.
4.1.8 Material value of the pieces
In chess, the material value of the pieces is not of ultimate importance, although the player
with the more valuable pieces will usually win the game. For the strategic evaluation, the
computer uses the following values:
Pawn = 100 points
Knight = 300 points
Bishop = 300 points
Rook = 500 points
Queen = 900 points
The king has no material value as it cannot be captured.
Here are some important terms regularly used: the difference in value between a knight (or
bishop) and a rook is called quality. If both sides capture pieces of equal value, the term
exchange is used. And it is not unusual for a player to lose a certain piece intentionally in
order to gain an advantage elsewhere; this is called sacrifice.

To select a mode, display it and press „E“. (Instead, ESC returns to the list of game types –§
2.) We suggest that for your first games you select NORMAL.
4.2.3 Starting with reduced material
By selecting the appropriate mode (§4.2.2), you can start a game with 2 or 3 types of piece
only. This offers practice for novices. The pieces start in their usual positions and play
proceeds normally.)

4.2.4 Making moves
To carry out your move, press the squares you are moving from and to. Similarly for the
computer’s move: press the “from” and “to” squares which are shown “blinking” on the LCD.
4.2.5 Captures
If you want to capture one of the computer’s pieces, proceed as if playing a regular move:
press your piece successively first on the “from” and then on the “to” square and remove the
captured piece (without pressing). The computer automatically registers that the piece has
been captured and calculates its next move.
If the computer captures one of your pieces, it also proceeds as in a regular move; however,
in this case, an “x“ symbol flashes between the “from” and “to” squares. Simply execute the
computer’s capturing move as if it was your own, ie take the piece off the board after pressing
the “from” and “to” squares.
4.2.6 Special moves
Castling: Make the king’s move first, and the computer directs you to move the rook.
En passant capture: Move the capturing pawn, then press the square of the captured pawn –
as indicated by the LCD.
Pawn promotion: Carry out the pawn move. Use ▲ or ▼ to select the type of piece for
promotion. When the right piece is shown on the LCD, press the promotion square (or „E“).
When promoting its own pawn, the computer always chooses a queen.
4.2.7 Retracting your play
If you have selected a “from” square but then change your mind, re-press the square or press
ESC, and start again.
After carrying out your move and the computer’s reply, you may want to retract these moves
and play differently. To retract a move, press ▼. In some cases you will simply need to move
the piece back, pressing on the “to” and “from” squares. In other cases, captured pieces will
also need to be replaced, or Reversi pieces “flipped”, etc. In every case, press the square that
is shown “blinking” on the LCD board and in the bottom line, as you add, remove or change
the piece on that square. Make sure that the position on the playing board corresponds to that
on the LCD board. You can then play a new move (or press SWAP to make the computer do
so.)
In Chess, by repeating the operation you can take back up to 8 moves by both sides, and the
retracted moves may be replayed by means of the ▲ button. In other games, only the last pair
of moves can be taken back.

4.2.8 Changing sides –the “SWAP” key
Before the game starts, while “White“ shows in the display, pressing SWAP results in
the computer taking the white pieces.
Also during the game, you can change sides by pressing SWAP, provided it is your
turn. When pressing SWAP after each move, the computer plays against itself.
Pressing SWAP while the computer is preparing to move will interrupt the calculation
and force it to make its move immediately. It will execute the best move calculated up
to that point, which will usually not be the best move in absolute terms.
4.2.9 Hints for playing chess against the computer
If you press one of your pieces then press LEGAL, the computer shows you all the moves that
this piece can legally make. The destination squares are indicated, one after the other, by the
“+” sign.
In the bottom line, a “+” sign shows you are in check; it is accompanied by a sequence of
beeps.
While the computer is displaying its own move, the Main Menu (§1.5) can be accessed and
contains an extra item: EVALUATE. By selecting this item you can see an assessment of the
position, e.g.
192 The computer thinks it has an advantage worth nearly 2 pawns.
-54 It has a disadvantage worth a little more than half a pawn.
Opening The move is in the computer’s “library” of standard openings.
Press ESC twice, and carry out the computer’s move.
If the bottom line displays CAREFUL! or SURE ?, the computer is offering a “tutor” message
–see § 12.1.6. You can continue by simply pressing ESC.
4.2.10 Chess problems (mate in 2 or 3 moves)
The computer can solve Chess problems for mate in 3 moves (unless they involve “under-
promoting” a pawn to a rook, bishop or knight).
(1) Set up the position, as described in § 12.8.
(2) Select the level with “no limit” (§ 4.2.12).
(3) Press SWAP. Provided there is a valid solution, the computer will keep analysing until
it finds the move, then display it in the normal way.
(4) After carrying the move out, you can play for the defending side, and the computer
will find the 2nd and 3rd moves of the solution
There is also a special feature for mate in 2 moves, incorporating 10 standard problem
positions. To use this feature, select “MT. IN 2” from the list of Chess modes (§4.2.2). Then
press ▲ or ▼ repeatedly to view the 10 problems, plus one other item: SU (= set up). To
select the problem position that is currently displayed, press „E“. Then press SWAP, and the
computer will find and display the solution.
If you press „E“ when SU is shown, this takes you into “set up” mode (§12.8). You can then
set up (e.g.) a problem position from a magazine. On exit from “set up” mode, press SWAP
and the computer will search for a mate in 2 moves.
