A unique combination of opponent and tutor, this computer is always willing to play, whenever you are! The Quick Start at the front of the manual is meant to get you started right away, and youll find more details on game operation in Section 1. After familiarizing yourself with the basics, go on to explore the rest of the manualand youll soon discover a variety of other special features and exciting game options! By the way, your computer knows and follows all popular rules of chessand you can be sure that it will never cheat!

LETS GET STARTED! 1.1 First, Install the Batteries Your chess computer runs on two AA (Type AM3/R6) batteries. Insert the batteries into the compartment in the base of the unit, as shown in the Quick Start. Use fresh alkaline batteries for longer battery life (up to 200 hours)! Turn the computer on by pressing GO/STOP, and a beep will signal that the game is ready to play. If the computer should fail to respond (static discharge can sometimes cause it to lock up), use a paper clip or another sharp object to press down into the hole marked ACL in the base of the unit for at least one second. This will reset the computer.

1.2 Ready to Play? Heres How to Move! Okay, its time to start a game! Its so easyjust follow these steps: a. Press GO/STOP to turn the computer on, if you havent already done so. b. Press NEW GAME to reset the computer for a new game of chess. Set up the pieces in their starting positions, with the White pieces nearest to you, as shown in the Quick Start. c. To make a move, lightly press down on the piece you want to move until you hear a beepthe sensory board will recognize your piece automatically, and the display will show the square that was pressed. d. Take that piece and gently press it down on the square you are moving to. Youll hear a second beep as the computer confirms the move. Youve just made your first full move of the game! Next, its the computers turn to move for Black.
1.3 Now Its the Computers Turn When the computer moves, it beeps and displays its move, with the from square flashing. Press the indicated piece down on the flashing from square until you hear a beep. The display now flashes the square the piece is moving to. Move that same piece to the indicated to square and press it down to complete the computers move. And its your turn again Please be aware that the following may sometimes occur while the computer is thinking: Game keys may need to be pressed down for two to three seconds before the computer responds. The clock display may occasionally skip a few seconds, and the duration between consecutive seconds may appear to be uneven. Game play will not be affected. 1.4 Change Your Mind? Take Back! When youre playing chess against this computer, nothing is set in stoneyou can change your mind or decide to play a different move whenever you want! You can take back two individual moves, or one move for each side. To take back the last move played, press TAKE BACK. The display will show the move to be taken back, with the original to square flashing. Press the piece down on that square. You now see the piece symbol, the color symbol, and the square that piece came from. Press the piece down on the flashing from square to finish the take-back. If the move taken back was a capture, the computer reminds you to put the captured piece back on the board by displaying the piece type and color, along with the location. Press this piece down on the indicated square. To take back another move, press TAKE BACK again. To continue the game, either make your next move or press PLAY to have the computer move next. 1.5 Game Over? Why Not Play Again! Whenever you finish a game (or if you give up on your current game), its easy to start over again! Press NEW GAME, and the computer will reset itself, putting all the pieces back in their initial positions. The same playing level will be in effect, but you can change it if youd like, as explained in Section 3.

2. ADDITIONAL BASIC FEATURES 2.1 Whose Move? Check the Display! You can always tell at a glance if the computer is currently thinking, and which side is to move! Whenever its your turn to move, PM appears in the display. When Black is to move, youll see S in the display. Although this is pretty straightforward during normal game play, where you are White and the computer is Black, weve included the following clarifications to help you with certain special situations: When you switch sides with the computer, so that you play Black and the computer plays White: Both PM and S will be displayed when it is your turn to move for Black, and neither one will be displayed when it is the computers turn to move for White. When Non Auto Mode is in effect: Both PM and S will be displayed when it is Blacks turn to move, and PM alone will be displayed when it is Whites turn to move. For information on switching sides, see Section 2.6.; for details on Non Auto Mode, see Section 4.2. 2.2 Special Chess Moves Captures: To capture, press down lightly on the piece you want to move, take the captured piece off the board, and press your piece down on the square of the captured piece. En Passant: In an en passant capture, the computer reminds you to remove the captured pawn from the board by flashing the pawns location in the display. Press down on the captured pawn before removing it from the board. Castling: The computer automatically recognizes castling after the King is moved. After you have pressed the King down on its from and to squares, the computer displays the Rooks move, with the from square flashing. Press down on this square, and the display flashes the square the Rook should move to. Press down on the Rooks to square to complete the move. Pawn Promotion: When you promote a pawn, first press your pawn down on the from square, as usual. The computer will flash the from square and the symbol for the Queen, along with the clock display. You now have two choices: (a) To promote to a Queen, simply complete your move by pressing your pawn down on the to square. The promotion will take place automatically. (b) To underpromote to a Knight, Bishop, or Rook, press the PIECE SYMBOL KEY for your desired promotion piece (@, #, or $). That symbol will be displayed, and pressing your pawn down on the to square will complete your move. When promoting, always remember to change your piece on the board! When the computer promotes a pawn, the display first shows its move, as usual, with the from square flashing. Press the from square, and youll see the symbol for the computers

IMPORTANT: Pressing NEW GAME clears the current game from memorybe careful not to press this key by mistake!
1.6 Too Easy/Hard? Change the Level! Your computer offers 64 levels of skill, each of which corresponds to one of the 64 board squaresmaking level selection so easy! Together with the built-in Teach Modes, you have a choice of 768 level setting combinations!

ENGLISH

At the start of a game, the computer will often move instantly because it is playing from memory, using its built-in book of opening moves. For details, see Section 2.9.
For complete details on all the playing levels, along with instructions on selecting levels, see Section 3.
promoted piece, along with the flashing to square. Simply press down on the to square, change the computers piece on the board, and continue your game! 2.3 Illegal Moves Your computer will never accept an illegal move! If you try to make one, youll hear a beep and the display will alternate between showing the from square and the time. Either move that same piece to another square, or press the piece back down on its original from square and move a different piece. If you dont move the computers piece correctly, youll also hear an error beep. This means that you are either moving the wrong piece, or moving the computers piece to the wrong square. Check the display and make the move again. If you press down on a piece and the from square is displayed, but you decide not to make that move, simply press down on that same square again to cancel. Then make another move. If you change your mind after entering your whole move, take the move back as described in Section 1.4. Caution: Be careful when playing with the sound turned off, since you wont be able to hear the error beeps! 2.4 Check, Mate, and Draw Check: When a King is in check, the computer first displays the move as usual. After the move is made, the display alternates between the time and ch:__ (if White is in check) or ch:)) (if Black is in check). Checkmate: When a game ends in checkmate, the display flashes End_ (if White has won) or End) (if Black has won). Draws: The computer recognizes draws by stalemate and immediate three-fold repetition. After a draw has occurred, the display will flash End(, along with the drawing move. 2.5 Interrupting the Computers Search Think the computer is taking too long to move? No problemyou can interrupt it any time! Simply press PLAY while the computer is thinking, and it will stop and make the move it is currently considering. This feature can come in handy for those of you who are impatientespecially when using Fixed Depth Levels C6 and higher, where the computer can occasionally take an hour or more to make its move. 2.6 Changing Sides with the Computer To change sides with the computer, press PLAY when its your turn to moveand the computer will make the next move for your side. Change sides as often as you wish! Want the computer to play the first move for White at the start of a new game? Press NEW GAME to reset the computer, and then press PLAY! Want to watch the computer play chess against itself? Press PLAY after each moveand watch as the computer plays for both sides of the board, one move after another.

Study its strategies, and you might improve your own game! When you switch sides with the computer, so that you are playing Black and the computer is playing White, the side to move indications will be shown as follows: Both PM and S will be displayed when it is your turn to move for Black, and neither one will be displayed when it is the computers turn to move for White. 2.7 Need Help? Ask for a Hint! Its easy to get assistance from the computer whenever you need it. On your turn, simply press and hold down HINT, and the computer will display a move suggestion! Note that pressing and holding HINT repeatedly may give you more than one suggested move in certain positions. The computer may take a few seconds to display a hint especially in complicated position. 2.8 Chess Clocks Your computer contains a built-in chess clock that keeps track of the time, with a four-digit display showing the total elapsed time for the side to move (computer or player) while that side is thinking. Heres an easy way to differentiate between the time displays at a glance: For the first hour, the display will show MM:SS (Minutes:Seconds), with a steady colon in the middle and a leading zero. If the total elapsed time exceeds one hour, youll see HH:MM (Hours:Minutes), with a flashing colon in the middle and no leading zero. Please also note the following points in regard to the chess clocks: The clocks will stop in certain situations, such as when moves are taken back, or when levels are changed or verified. In these cases, the times are retained in memory, and the clock resumes when play is continued. Occasionally, while the computer is thinking, the display may skip a few seconds, or the duration between consecutive seconds may appear to be uneven. Your game will not be affected. 2.9 Built-In Openings At the beginning of a game, the computer will often move instantly on many levels. This is because it is playing from memory, using its own built-in book of opening chess moves, which includes most major openings. If the current board position is in its book, the computer will play a response to that position automatically, instead of having to think about the move! 2.10 Auto Power Down Whenever its your turn to move and you havent made a move or pressed a key for 20 minutes, the computer will automatically turn itself off to conserve batteries. To continue your game, press GO/STOP to turn the unit back on. Note that the computer will not turn itself off while it is thinking.

2.11 Game Memory If you want to interrupt your game for any reason, you may do so by pressing GO/STOP. Play is then suspended, and the computer will store your current position for up to two years (with fresh alkaline batteries). When you switch back on again, simply continue right where you left off! 3. THE PLAYING LEVELS With 768 level settings to choose from (incorporating the Teach Modes), you can definitely learn and grow with this chess computer! When you set the level, keep in mind that the more time the computer has to think about its moves, the stronger and better it playsjust like a human player!
Please refer to A QUICK AND EASY GUIDE TO LEVEL SELECTION! for an overview of all the levels.
As shown in the Level Selection Chart, each playing level corresponds to one of the 64 board squares. The levels are categorized into three different groups: Fun Levels (Squares A1-B8), Fixed Depth Levels (Squares C1-D8), and Casual Levels (Squares E1-H8). On the higher levels, the computer thinks more deeply and becomes a progressively more challenging opponent. The highest level in each of the groups produces the best moves the computer can make within the constraints of that particular level setting. Experiment a littlestart out with some of the lower level settings, and advance to the more difficult levels as your skills grow! Note that on some of the higher levels, the computer may take a long time to complete its search. If you want to force the computer to stop thinking and make a move, simply press PLAY at any time. Press LEVEL to enter Level Mode, and the current level is shown, with the display alternating between the Level Square and the Level Name. As an example, Level A4 (Fun Level 4) displays as L:A4 and Fu4. To change the level, simply press a board square (using the Level Selection Chart as a guide), and that level will be displayed. Press LEVEL again to exit Level Mode, with your newly selected playing level in effect. Other important points to remember regarding levels: If you press LEVEL to verify the level, but you dont want to change levels, press LEVEL again to exit without making any changes. You can use LEVEL to check the playing level while the computer is thinking, but you cannot change the level until its your turn to move. Pressing NEW GAME resets the computer and retains the current playing level. 3.1 Fun Levels (Squares A1-B8)

L:B8 / Fu16 If you are a novice or beginning player, the Fun Levels are especially for youtheyll give you the opportunity to beat the computer for a change! Here, the computer does not exhaustively search for the best available move, as you would normally expect. Instead, it disregards scores and uses a strong randomizer to deliberately weaken play which causes it to sometimes make moves that are not necessarily the best it has found. This variability makes the computer prone to some very human errors in judgment. Beat the computer by capitalizing on its mistakes, and you may soon discover that you can win games against friends in the same manner! The Fun Levels start out easy and get a little stronger as they go, allowing you to strengthen your playing abilities along the way. 3.2 Fixed Depth Levels (Squares C1-D8)

L:D5 / Fd13 D6. 5 ply+. L:D6 / Fd14 D7. 5 ply++. L:D7 / Fd15 D8. 6 ply. L:D8 / Fd16 On the Fixed Depth Levels, the computers search depth is limited to a certain number of moves, or ply. A ply is an individual move, or a move for either side. For example, on Level C1, the computer searches to a depth of one ply, and thus looks ahead only one individual move. On this level, therefore, it will often overlook a mate in one. This produces weaker play, giving beginners a better chance of beating the computer! Use these levels to sharpen your skillsas you conquer each level, graduate to the next! The levels marked with plus signs (+ and ++) indicate small, incremental jumps in the search depth. On these levels, the computer will look ahead that particular number of ply, plus a few extra moves (+), or a few more selected extra moves (++). Note that the computer may take a long time to move on some of the Fixed Depth Levels. On Levels C6 and above, for instance, it might not be unusual for the computer to think
