Chess 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. ...
Page 12
(a) The king moves one square at a time, in any direction – forwards, backwards, sideways or diagonally (b) The queen can move any number of squares at once, in a straight line – horizontally, vertically or diagonally ...
Page 13
(d) The bishop moves diagonally, any number of squares at a time . 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 ordinary move of the pawn is simply one square straight forward – it cannot retreat. 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 ...
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);...
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. ...
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.

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”...
Changing sides – the “SWAP” key 4.2.8 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.
Check – Mate – Draw 4.2.11 If the computer announces “check”, it will do so by showing the “+” symbol in the display. This is just a reminder that you must counter the check with your next move. If you “check” the computer, no acknowledgement is given.
4.2.13 Style In addition to the various play levels. you can select the computer’s playing style. Five different style levels can be selected, which can be roughly described as follows: very passive passive normal active aggressive To set the computer’s Chess style: (1) Use START and ▲...

Checkers How to play checkers 5.1.1 The Checkers board and pieces Checkers (or Draughts) is played on an 8x8 chequered board, but the pieces only move on squares of one colour. Each of the opponents (“Black” and “White”) starts with 12 pieces, arranged like this: The players take it in turns to move one piece at a time.
Multiple captures: If a capturing piece lands on a square from which it can make another capture, then it must do so – as part of the same move. In the left-hand diagram below, the black man on a1 must capture the white man on b2, landing on c3. The same man must then jump to a5 (removing the white man b4), then...
Here, the black queen on B4 can either capture the white piece on C5 and end up on D6, or capture the white piece on C3 and end up on D2. A normal black piece could not execute the capturing move via C3 to D2, as it only moves forward.
Reversi How to play Reversi 6.1.1 The board and pieces In Reversi the players use a set of 64 discs, or playing pieces, which are coloured white on one side and black on the other. At the start, the 8x8 board is empty. One player (“Black”) has 32 pieces with the black side turned up.
Also, several pieces in one line can change colour simultaneously. Eg, with three white pieces in a horizontal, vertical or diagonal line between a black piece already in position and another one just moved there, three change colour simultaneously. One piece can change colour several times during a game.
Four-in-a-row The rules 4 Four-in-a-row is a game for two players. The game board is limited to 7 vertical rows. Although the rows usually offer space for 6 pieces, the computer offers you the choice of using a larger board. One player (“White“) uses the white pieces, his opponent (“Black“) the black pieces.
Fox and Geese The rules One player has four white pieces – the “geese”, which start on b8, d8, f8 and h8. On each turn, he moves a goose diagonally forwards onto an adjacent vacant square – like a man in Checkers.
Grasshopper The rules Each player has 10 pieces which start the game in the area in the bottom corner on his right. White moves first. On his turn, a player moves a piece in one of two ways: (a) The piece can move to any adjacent vacant square – e.g.
10 NIM 10.1 The rules In the “default” starting position, there are 4 piles of pieces: The players take it in turns to remove pieces from the board. On his turn, a player takes a number of pieces from a single pile –...
11 Northcote’s Game 11.1 The rules The “default” starting position The player with the white pieces begins by moving one piece looks like this: forward. It can go as far as he likes, but must stop short of the black piece same column.
12 Special Features 12.1 Options You can adjust various parameters after selecting OPTIONS from the Main Menu (§ 1.5). This displays the first item in the “Options Sub-menu”. Press ▲ or ▼ repeatedly to view all the items: SOUNDS see § 12.1.1 STYLE (chess only) see §...
“Referee” mode 12.1.4 In “referee” mode, the computer allows you to play for both sides. (For example you can play against a friend – the computer will merely act as a “referee”, checking that the moves are legal announcing result etc.) switch this...
“ You could checkmate me” “I can take that piece.” “You could win material worth 3 pawns.” Press SWAP again, to see the move that the computer thinks you have missed. Press ▼ and take your move (see § 12.3). Press ESC to let your move stand.

Reverse board ( ) 12.7 You may want Black to play “up the board” in Chess (etc.), or “down the board” in Checkers. To switch the board round, select INVERT from the Main Menu (§...

You can now play from the new position – make a move or press SWAP to instruct the computer to do so. If play is impossible from the position you have constructed, the display shows ??? and the computer remains in “set-up”...
13 Troubleshooting Your computer has been manufactured and thoroughly checked with great care before delivery. It is therefore unlikely to contain any technical fault. Experience shows that most apparent ”faults” result from wrong user operation, incorrect data input when preparing a move, or simply from pressing the wrong key.
13.3 The computer does not accept your move You want to „E“ a move, but the computer refuses to accept; the most likely cause: 13.3.1 In all game types Always ensure that any input for a move is properly executed by pressing the target or “to” square.
The computer makes ”illegal” moves 13.5 If the computer makes what seem to you to be illegal moves (which is basically impossible, of course), one of the following could be the cause: Verify that the position of the pieces on the playing board corresponds to that in the computer’s internal memory.
