1. LETS GET STARTED!

1.1 First, Install the Batteries/Optional AC-DC adapter
Your computer runs on four C (Type AM2/R14) batteries.
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

ENGLISH

TABLE OF CONTENTS
Insert the batteries into the compartment in the base of the unit, making sure to observe the correct polarity. Use fresh alkaline batteries for longer battery life! If you would rather not power your unit with batteries, you may purchase an optional AC-DC adapter. Please use only the adapter specified in Section 9.3. Using any other adapter could damage the computer and will invalidate your warranty. Please also read the precautionary information regarding adapter use in Section 9.2. When using an adapter, first plug it into a wall outlet, and then into your computer. Important: To ensure that the computers memory contents are not lost, keep good batteries installed in the unit even when you are using an AC-DC adapter. Turn the computer on by pressing GO/STOP, and a beep will signal that the game is ready to play. If the computer fails to respond (static discharge may 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.
a different move whenever you want! When its your turn to move, simply press TAKE BACK. The display shows the move to be taken back, with the original to square flashing and indicated by board lights. Press the piece down gently on the indicated square, and the computer shows you where that piece came from by flashing that display and using board lights to point to that square. Press the piece down on the from square to complete the take-back. Repeat this as often as youd like, taking back up to 50 individual moves (or 25 moves for each side). To continue playing at any point, just make another move on the board! After taking back a capture, the computer will make sure your board is still set up correctly by reminding you to put the captured piece back on the board! It does this by displaying the piece symbol and its location, along with a + symbol, and turning on the board lights for that square. Put the indicated piece back on the board and press that square to complete the take-back.
MAKING THE COMPUTERS MOVE: AN EXAMPLE!

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! Reset the computer for a NEW GAME by pressing the CLEAR and ENTER keys together, and a series of beeps tells you the computer is ready. The same playing level will be in effect, but you can change it if youd like, as explained in Section 3. IMPORTANT: Resetting the computer for a new game clears your current game from the computers memorybe careful not to press these keys by mistake!

After the computer moves, its up to you to make its move on the board! Here, the display indicates the computer wants to move its Black pawn (]!) from d7 to d5. Pick up the d7 pawn (indicated by the board lights) and press it down lightly on Square d7. The board lights now point to Square d5. Press the pawn down on Square d5 to complete the computers move. Now its your turn again!
1.6 Too Easy/Hard? Change the Level!
When you first turn your computer on, its automatically set to Normal Playing Level A4 (five seconds a move). However, you have 64 different levels to choose fromyoull want to try them all out! For descriptions of the playing levels and how to change levels, see Section 3.
2. MORE FEATURES TO EXPLORE
2.1 Whose Move? Check the Display! When the computer plays Black, it flashes a black square in the display while it is thinking. After it has moved, a white square shows that it is now Whites turn to move. You can tell at a glance if the computer is currently thinking, and which side is to move! 2.2 Special Chess Moves Captures: To capture, press down on the piece you want to move, remove the captured piece from the board, and press your piece down on the square of the captured piece. Captures are displayed as in E5F4. En Passant Captures: In this type of capture, the computer reminds you to remove the captured pawn by displaying the pawns position, along with a minus sign, and using two board lights to indicate that square. 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 uses the display and board lights to remind you to move the Rook. Press down on the Rooks from and to squares to complete the move. Note that Kingside castling is displayed as 0-0, and Queenside castling as 0-0-0. Pawn Promotions: When you promote a pawn, first make your move as usual, pressing your pawn down on its from and to squares. Next, press the Piece Symbol Key for your desired promotion piece (%, $, #, or @). The computer recognizes your new piece immediately, and begins thinking about its next move. Remember to change your piece on the board! When the computer promotes a pawn, the display shows both the pawn and the promoted piece. Dont forget to replace the computers pawn with its new piece.
2.3 Illegal Moves Your computer will never accept an illegal move! If you try to make one, youll hear a low double beep, and the board lights and display will simply continue to show the square the piece came from. Either move that same piece to another square, or press the piece back down on the original from square and move a different piece. If you dont make the computers move correctly, youll also get an error beep. This means you are either moving the wrong piece, or moving the computers piece to the wrong square. If the computer wants to move its pawn from C7 to C5, for example, and you press down on C7 and then C6, the display shows :C5 briefly, pointing out your error. The display then returns to showing the move again (C7-C5), and the computer expects you to press C5 to complete its move. 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. 2.4 Check, Mate, and Draw When a King is in check, the computer first displays its move as usual. After the move is made, CHECK flashes in the display for a few seconds, along with the checking move. The display then goes back to showing the clock. If the computer discovers a forced mate against its opponent, it first displays its move as usual. After the move has been made on the board, the computer flashes a mate announcement along with the move for several seconds (e.g., =in2 for a mate in two moves). The display then goes back to showing the clock. When a game ends in checkmate, the display flashes MATE (along with the mating move) for a short time after the move is made. The display then goes back to showing the clock. The computer recognizes draws by stalemate, three-fold repetition, 50-move rule and insufficient material. After a draw has occurred, the display flashes End,EnD:3,End:50,or End:In (along with the drawing move) for a brief time after the move has been made. The display then goes back to showing the clock.

Are you a beginning player? You have lots of choices! Check out the Fun Levels, the lower Training Levels, or the Self-Adaptive Weak Levels. These levels all restrict the computers search depth in different ways, resulting in weaker play and giving you the chance to learn more about the game and perhaps even beat the computer occasionally! Are you an intermediate or more advanced player? Try the Normal, Training, or Tournament Levels. The Normal Levels range from easy all the way up to a difficult 10-minute response time, and the Tournament Levels are extremely challenging. And dont forget to try the Blitz Levels for some fast and exciting games of Speed Chess! By the way, for Tournament and Blitz Games, you can activate the built-in Bronstein Clock, as youll see in Section 5.3! Want to experiment? Use the Mate Search Levels to solve problems up to mate in eighttry searching from a position in one of your own games, or set up an actual mate problem. Choose the Infinite Level to have the computer analyze complicated positions for hours or even days!

3. THE PLAYING LEVELS

Your chess computer offers 64 different levels of play! When you set the level, keep in mind that when the computer has more time to think about its moves, it becomes stronger and plays betterjust like a human chess player! For an overview of all the levels, refer to the Level Chart. The levels are also described individually in this section. Setting a Playing Level
See USE THIS CHART TO SELECT A PLAYING LEVEL! for an illustrated look at how to set a level and a chart showing all the levels at a glance.
There are two methods of setting levelsby using the game keys or pressing the board squares. Whichever method you use, always press LEVEL first to enter Level Mode, and the computer will display the current playing level. When you enter Level Mode the first time, the computer is set on Normal Playing Level A4 (with an average response time of five seconds a move), and the display shows L0:05. To select a level by using game keys: After entering Level Mode by pressing LEVEL, change levels one at a time by using the BLACK/> and </WHITE keys. As a shortcut, press LEVEL repeatedly to skip over eight levels at a time. When the display shows your desired level, press ENTER to enter your new level into the computer and exit Level Mode. To select a level by pressing board squares: As shown in the Level Chart, each of the 64 squares corresponds to one level. After entering Level Mode by pressing LEVEL, press a square to activate a level, using the chart as a guide. When you press down on the desired square and that level shows in the display, press ENTER to enter your new level into the computer and exit Level Mode. Note that when making your selection via the board squares, pressing CLEAR has the same effect as pressing ENTERit enters your level into the computer. To verify the level without changing it: If you press LEVEL to verify the level but you dont want to actually change levels, press CLEAR. This returns you to normal play without changing the level or clock settings, even while the computer is thinking. Other important points to remember regarding levels: Changing the level always resets the chess clocks. We dont recommend changing levels while the computer is thinking, since the clock is reset and the current search is aborted. If you must do this, first press ENTER to abort the computers search, and make its move on the board. Then, take back the computers move and change the level. Finally, press ENTER to make the computer start thinking on the new level. The LEVEL Key is also used to enter Teach Mode, as you will see in Section 6. If you accidentally press a PIECE SYMBOL KEY while in Level Mode, you will enter Teach Mode and lose your current game after exiting Level Mode. To prevent this and retain your current board position, press CLEAR to cancel Level Mode.

L10:00 When you choose one of the Normal Playing Levels, you are selecting an average response time for the computer. Note that the times are averaged over a large number of moves. In the opening and endgame, the computer tends to play faster, but in complicated middlegame positions, it may take longer to move. 3.2 Infinite Level (Square B8)

LEVEL MOVE TIME DISPLAY

D6.. 45 minutes.. 0:45;99 D7.. 60 minutes.. 1:00;99 D8.. 90 minutes.. 1:30;99 On the Blitz Levels (also called Speed Chess or Sudden Death Levels), you set the total time for the whole game. If game time is exceeded, the computer flashes time (TImE) along with the elapsed time, to show that the game is over. If you select a Blitz Level, you may want to set the chess clocks to display countdown time instead of elapsed time (see Section 5.1). When game time runs out, the countdown clock automatically reverts back to the normal clock display. Your computer also offers the option of using Bronstein Clock time controls when playing Blitz games! For complete details, see Section 5.3. 3.5 Fun Levels (Squares E1-E8)
B8. No time limit. 9:99;99 On the Infinite Level, the computer will search indefinitely, until it finds a forced mate or forced move; until it has fully searched the position to its maximum depth; or until you stop the search by pressing ENTER. If you halt the search, the computer makes the move it currently thinks is best. Try experimenting with this levelset up interesting board positions and let the computer analyze them for you! It will think for hours or even days on end, trying to come up with the best possible move. And dont forget to watch the computer as it thinkstake advantage of the Rotating Display feature described in Section 5.2! 3.3 Tournament Levels (Squares C1-C8)

Fun: 8 *Increase as users time per move. Are you a novice or beginning chess player? If so, these levels are especially for you! Here, the computer restricts its search so that it deliberately plays weaker and gives you a better chance to win! The Fun Levels start out easy and get a little harder as you go. The computers playing strength goes up gradually from Levels E1 to E6but be prepared for some stiffer competition when you reach Levels E7 and E8! These two highest Fun Levels represent a much greater jump in playing strength, and you ll notice that theyre quite a bit more challenging. Try out all the Fun Levelsas you beat each one, go on to the next! By the time you reach Levels E7 and E8, your improved chess skills should make them much easier to handle! 3.6 Mate Search Levels (Squares F1-F8)

H6. Self-Adaptive 6. Adt: 6 H7. Self-Adaptive 7. Adt: 7 H8. Self-Adaptive 8. Adt: 8 The Self-Adaptive Weak Levels are perfect for players who are just starting out. Here, beginners have the chance to interact with the computer on eight weakened levels of varying ELO rating strengths, and the computers strength is adjusted to match that of the player. On the lowest level (H1), the computer will set its playing strength to a deliberately weakened setting of about 350 ELO. On the upper end, Level H8 matches the strength of the player by putting the ELO difference at zero. As you play, the computer will try to keep this difference constant. That is, if you play badly, the computer will not play well eitherbut it will fight to win back material it has lost to you, if necessary. On the other hand, if you play stronger, the computer will also play stronger. Work your way up!

INFO MODE AT A GLANCE!

4. INFO MODE: WATCH THE COMPUTER THINK!
Imagine this: Youre playing chess against a friend, and its his move. Youd love to know what move hes thinking about, and youd really like to get his opinion of the board position. But, of course, you wont askbecause thats just not done! Well, guess whatwhen you play against this chess computer, you can ask anything you want, and youll get all the answers! In fact, you can get an incredible amount of information about the computers thought process. On request, it will show you the move its thinking of, the line of play it expects after that move, its evaluation of the current board position, how deeply it is searching, and more. As you can imagine, studying this information can help you learn so much more about chess!
Using Info Mode How do you access all this game information? By using Info Mode at any time! If you do this while the computer is thinking, youll see the information displays change as the computer considers different moves and searches deeper!

Just Ask! In case you missed this feature when it was mentioned in Section 4.1, we wanted to point it out againif you ever need advice on a move, you can always ask the computer for a hint. Simply press INFO when its your turn to move, and the computer will show a suggested move for your side!
When the computer plays White from the top of the board (Section 5.1, Option G1), be sure to set up the pieces correctly! Notice that the Kings and Queens are positioned differently, and the board notation is reversed.
When the computer is first powered on, certain default options are set. Options which are automatically in effect at the first startup are shown in the chart with a plus, and options which are off are shown with a minus. Whenever you reset the computer for a new game, most of your selected options are carried over to your next game. Some exceptions are Auto Answer, which is automatically set back to ON when you start a new game, and Play White from the Top, which is automatically set back to OFF.

5.1 Operation Mode Options (Squares A1-H1) Press OPTION once to select the Operation Mode Options. Then use the BLACK/> and </WHITE keys to select options within this group, and press ENTER to turn options on (+) or off (). Or, simply press the option squares to turn options on or off.
5. OPTIONS FOR FUN AND VARIETY
In addition to all the features youve learned about so far, your chess computer also offers many other exciting game options! All of these options are user-selectable at any time during a game. They are described individually in this section, and summarized in the Option Mode Chart. Selecting Game Options There are two methods of setting options, as described belowby using the game keys or pressing board squares.
See THE BASICS OF OPTION MODE: HERES HOW! for a chart summarizing how to use Option Mode, and an overview of all the options.
The Game Options are divided into three groups: Operation Mode, Rotating Display Mode, and Bronstein Clock Options. Pressing OPTION cycles from one group to another, and each group contains a different set of options. For Operation Mode and Rotating Display Mode options, the BLACK/> and </WHITE keys are used to cycle through the options within each group. For each option, a plus (+) in the display indicates the option is ON, and a minus () means the option is OFF. Press ENTER to turn each option on or off as it is displayed. For Bronstein Clock Options, press ENTER to cycle through the different clock options. The clock option you choose to display will be the selected time control when you exit Option Mode. If you decide not to activate the Bronstein Clock after all, simply press ENTER repeatedly until the display once again shows -bron. (see Section 5.3) After you have made all your option selections from any or all of the option groups, press CLEAR to return to normal game play. Another method of selecting game options is by pressing the option squares. As shown in the Options Chart, Squares A1-H1, A3-H3, and A4 can be used to turn options on and off. First, press OPTION to enter Option Mode; then press a square to access an option, using the chart as a guide. For Operation Mode and Rotating Display Mode options, pressing the square repeatedly turns that option on and off, with plus (+) for ON and minus () for OFF.

5.2 Rotating Display Options (Squares A3-H3) Normally, the computers display shows the time for the player to move. However, the computer can also display other information, as described in Section 4 (Info Mode). The Rotating Display feature works hand-in-hand with Info Mode, since it allows you to choose which of the Info Displays you want to see, and then cycles your choices in about onesecond increments. You may turn on any or all of the Rotating Display options, as desired.
1. Press LEVEL, and the current playing level is displayed.

IMPORTANT: The Rotating Display feature is only activated WHILE THE COMPUTER IS THINKING.
Press OPTION twice to select the Rotating Display Options. Then use the BLACK/> and </WHITE keys to select the options you want to see rotated in the display. The options are described below and summarized in the Option Mode Chart in this section. Press ENTER to turn these options on (+) or off (). Or, simply press the option squares to turn the options on or off. If you think the display information is changing too quickly when it rotates, press INFO to freeze the display. Successive presses of INFO and the BLACK/> and </WHITE keys will allow you to cycle through all the displays manually, as described in Section 4. To start the display rotation again, press OPTION followed by CLEAR. In any event, when the computer starts thinking about its next move, the display automatically starts rotating again. The game information you can see while the computer is thinking includes the following: rd:1 to rd:4 = the predicted line of play (up to four individual moves) rd:E = an evaluation of the current position rd:d = the computers search depth, and the number of moves examined so far in the game rd:n = the number of nodes searched per second rd:t = the amount of time the move has taken so far When requested information is not available, the display will show a series of dashes ( ). For complete descriptions of these options and details on exactly how to interpret the displays, see Section 4. 5.3 Bronstein Clock Options (Square A4) On the Blitz and Tournament levels, you have a fixed amount of time for each game, and the remaining time decreases as you think. On these levels, players often find themselves running out of time towards the end of the gamestruggling to try and make good moves in a hurry, and often ending up making inferior moves instead. The Bronstein Clock option offers special time controls that can help alleviate such problems. This is accomplished by adding a certain amount of time back to your remaining time after each move, where the remaining time for the whole game is only reduced if you go over this fixed time level. Heres an example: Lets say youre playing Blitz Level D4, where you have a total of 20 minutes for the whole game. Activating the Bronstein +b0:10 option will give you a maximum 10 seconds time compensation per move (added after you make your move). Note that you cant gain extra time or increase overall thinking time by playing each move more

7. STUDY MODE: TRY RATING YOURSELF!
Want to try out a fascinating learning tool? Then Study Mode is exactly what youre looking for! Twenty famous and exciting games from the history of chess are built into your computer, incorporating 413 different chess puzzles. Its up to you to play through the games and make the correct moves that were played for the winning side in the original games! This feature offers great potential for improving your chess knowledge, while allowing you to practice your skills and learn all about making the best move in a particular position! And, to make this feature even more exciting, youll actually be able to determine your own ELO rating after completing each Study Game! Understanding ELO Ratings Before we explain how to use Study Mode, just a few words regarding the concept of chess ratings. A rating is a way to measure chess performance or describe relative playing ability. The international body which governs chess is called FIDE, or Fdration Internationale des checs, and FIDE ratings are sometimes referred to as ELO ratings. The United States Chess Federation (USCF) uses a similar rating system. Ratings are usually four-digit numbers, with stronger players having higher ratings. On the high end of the scale, masters rank in at 2200 and above, and international grandmasters are rated at 2500+. Want to know where you stand? Go ahead and try out Study Mode! Using Study Mode
See STARTING UP STUDY MODE! for an example of Study Mode basics.
Set up the pieces for a new game, and press STUDIES to enter Study Mode. The display will show the current Study Game (as in tst:1 for Study Game 1). Press BLACK/> or </WHITE to cycle through the 20 Study Game displays, one at a time, from tst:1 to tst:20. When your chosen Study Game is displayed, press ENTER to select that game. (Note that pressing CLEAR at this point will cancel Study Mode and return you to normal play.) After pressing ENTER, the computer will automatically reset itself for your selected Study Game. Youll see PLAY displayed briefly, and then the first move is displayed. Follow along, making the moves on the board as they are shown. When you come to the first puzzle move, youll hear a series of beeps and the clock will start a three-minute countdown. Time for you to guess the White move that was played in that position in the original game! Heres how it works: There is only one correct move per study position. The puzzle moves will always be for White (the winning side, in each case). The computer will play the Black moves, and you must make those moves on the board. If you make the correct move, the computer will show the points you get for that move, as in Pnt:4. Depending on the difficulty of the move, youll be awarded from 1 to 8 points. The computer will then go on to the next move. If you make the wrong move, youll hear an error beep and see briefly in the display. Points will automatically be deducted for the incorrect guess, and you can put your piece back on its original square. For difficult moves, youll be allowed more than one guess. After the maximum number of wrong guesses, the correct move will be displayed automatically. If you still havent found the move at the one-minute mark, youll hear three warning beeps. Then, at the 10second mark, youll get a ticking sound. When your time finally runs out, the correct move will be displayed. Make that move on the board. After the first puzzle move, all the rest of the White moves in the game are subsequent puzzle moves. In other words, youll be guessing each White move, all the way until the end of the game! At the end of the game, the computer will count up and display your total points score on the study game (as in tot:14), up to a maximum of 50 points. You will then see your estimated ELO rating, based on how well you did! The display alternates between the points and the ELO rating until you press CLEAR or start a new game. If your first try

TRY OUT POSITION MODE!

See TRY OUT POSITION MODE! to get an idea of how this feature works.
Position Mode is an exciting feature which lets you set up special board positions to play from, or problems you want the computer to solve! Caution: All previous moves in your current game will be erased from the computers memory if you make changes to the position during a game. Press POSITION to enter Position Mode, and the display shows -POS-. You can change or set up a position whenever it is your turn to move.
