1. USING YOUR CHESS COMPUTER
Battery Installation Your chess computer runs on 3 AA (AM3/R6) batteries. For longer battery life (up to 600 hours), use fresh alkaline batteries. Slide back the cover in the back of the case and insert the batteries as shown in Figure 1-1. Reinstall the cover and press GO/STOP to turn the computer on. If the computer does not respond, use a paper clip or other sharp object to press into the hole marked ACL in the base of the unit for at least one second to reset the computer. After the battery is inserted or ACL is pressed, the computer runs a self-test. 3 beeps indicate that the test is OK; a buzz or silence indicates a problem and you should check it with your local distributor.
Note that putting in new batteries or pressing ACL will reset the computer and its memory, losing any game that it might contain.

Fig. 1-2

Making Moves Follow these steps to start a game. a. If necessary press GO/STOP to turn the computer on. b. Set up the chess pieces in their starting positions with the White pieces nearest to you, as shown in Figure 1-2, and press NEW GAME. The computer will indicate on the display that you should play a White piece 00:00

PRESS PRESS

Note that pressing NEW GAME will cancel Teach mode or Openings Coach if either is selected, or switch off the Non Auto function.
c. To make a move, lightly press down on the piece you want to move until you hear a beep (see Figure Fig 1-3). The computers sensory board registers your move, and the display shows on the left side the from square that was pressed E2:zz d. Take the piece and lightly press it down on the square you want to move to. A second beep sounds and the computer briefly shows the to square on the right side of the display E2:E4 As soon as your move is finished, if you have Sound and Coach selected, the display will show Cocch while it evaluates your move. Two low tones are emitted if the move is considered bad. e. Then it is the computers turn, and the computer starts thinking about its move. However, in the early stages of a game the computers response is often virtually instantaneous, because it is playing moves already stored in its openings library (see Section 2.9).

Fig. 1-3

Fig. 1-4
The Computers Move When the computer is ready, it beeps and shows the from and to coordinates of its move in the display, as shown in Figure 1.4. For an example, (see Figures1-5a and b). Press the indicated piece down on its from square (E7, in this case), until you hear a beep and the from side of the display changes to show the color and symbol for that piece. (Figure 1 shows the symbols.) Next press that same piece down on the second square in the display the square the computer wants to move to (E5 here). Once you press E5, the display clears and you have completed the computers move! The display then indicates again that it is your move. Change Your Mind? Take Back! If you change your mind about a move, you can take it back. Press TAKE BACK while it is still your turn to move. The display shows the to square. Press the piece down on that square. You now see the piece symbol and the square that piece came from. Press the piece down on the 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 its square for you. Press this piece down on the indicated square. To take back another move, press TAKE BACK again. You can take back for up to 14 individual moves (or 7 moves for each side), allowing you to experiment and try out various What If? approaches. To continue the game, either make your next move or press PLAY to have the computer make it for you. Figures 1-6a and b show an example of taking back the Knight move from G8 to F6. After

Fig. 1-5a

Fig. 1-5b

INTRODUCTION

pressing TAKE BACK, the display shows F6, the square the Knight moved to (Figure 1-6a). Press down on F6, and the display changes to show the piece color and symbol (Black Knight) and the square that piece came from (Figure 1-6b). Press the Knight back down on G8.

Fig. 1-6a

Note that en passant captures cannot be replayed if the take back of its previous move was not allowed.

5. 6. 7. 8.

Check, Mate, or Draw! When a King is in check, the display shows the check symbol (alternately with the clock display if the clock is running). When the game ends in checkmate, draw by stalemate, draw by immediate 3 fold repetition or draw by 50 move rule, the End symbol is displayed. These symbols are shown in Figure 1. Start a New Game Press NEW GAME to start a new game at any time, using the currently selected level and the previous setting of the sound feature. Since pressing NEW GAME clears your current game from the computers memory, be very careful not to press this key by mistake.

Fig. 1-6b

Change Levels Your chess computer offers you 64 levels of play, each of which corresponds to one of the 64 board squares. Together with the eleven built-in Extended Teach modes, you have a choice of 768 level settings. Press LEVEL to enter Level mode, and the current level is displayed (eg the Level equivalent to board square A3 shows L:A3 alternately with Fun3. To change the level, simply press a board square, and that level will show in the display. Press LEVEL again to exit Level mode. For more information on the playing levels, see Section 3. Openings Coach Your computer has 16 openings sequences such as the Italian Opening or the Queens Gambit for you to learn. Press OPENINGS COACH and then press one of the squares from A1 to B8 to select one of the openings. Press the square again to choose how much help you get from the computer, and then press OPENINGS COACH again to start practicing or to test your knowledge. More details are in Paragraph 3.12.

Fig. 2-1a

2 ADDITIONAL COMPUTER FEATURES

2.1 Chess Clocks Built in chess clocks keep track of the time for you and also for the computers side, with a four-digit display showing the total elapsed time or the remaining time for each player alternately when it is his turn. After you have entered the computers move the display shows your chess clock until a key or square is pressed. However, it keeps tally of your time until the to square is pressed. After you make your move, the display immediately switches to the computers clock while it thinks, until it indicates that it is ready to move. However, the computer may instead display Conch after your move while it analyzes whether you made a good or a bad move. If it thinks your move is not good, it sounds two low tones. For the first hour of the game or the remaining time is less than a hour, the display will show MINUTES:SECONDS, with a steady colon. If the total elapsed time exceeds one hour, or the remaining time exceeds one hour, the display will show HOURS:MINUTES, and the colon becomes a flashing colon while the clock is showing.

Fig. 2-1b

Fig. 2-1c
Notes: The clock stops if you verify the level, if you verify the board, or if you turn the computer off. In each of these cases, however, the times are retained in memory, and the clock display resumes when play is continued. The clock resets if you change level or press a square while in Level Mode. When your King is in check, the display shows check alternately with the chess clock. If you are playing in a level which is against the clock, the clock counts down from your selected time to show time remaining. When the first clock reaches zero, there will be three low tone beeps to signal that time has run out. The clock will then begin counting time up from zero. In the levels where time is not part of the competition, the clock counts upwards to show the total elapsed time. If you take back while playing against the clock, the clock does not reverse for each take back. It simply stops until you start making a move again.)
2.2 Capturing and Special Moves a. CAPTURES: To capture, press down lightly on the piece you want to move, take the captured piece off the board, and press your piece on the square of the captured piece. b. EN PASSANT: In an en passant capture, the computer reminds you to remove the captured pawn from the board by displaying the pawns location. Press down on the captured pawn before removing it from the board. See Figure 2-1a, b and c. c. PAWN PROMOTION AND UNDER-PROMOTION: When you promote a pawn, first press your pawn down on its from square, as usual. The computer displays your from square and the Queen symbol (alternately with the clock display). As soon as you press your pawn down on the to square, it automatically becomes a Queen. Remember to change your piece on the board! If you wish to under-promote your pawn to Rook, Bishop, or Knight, then press the appropriate Piece Symbol key in between pressing the from and to squares. When the computer promotes a pawn, it will show the from and to square as

Fig. 2-2

usual. After you press its from square, the display indicates the piece type that the pawn will be promoted to by showing the piece symbol and the to square. Press down on the to square with the indicated new piece to complete the computers promotion move. d. 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 from square. Press down on this square. The computer then displays the Rook symbol, along with the square the Rook should move to. Press down on the Rooks to square to complete the move (see Figure 2-2). 2.3 Illegal Moves Your computer will never accept an illegal move. If you attempt an illegal move, the computer gives a low tone error beep and the display keeps showing the from square. Press on that square to clear the illegal move; then move again. Also, if you should move the computers piece incorrectly you will also hear an error beep. This can happen if you move the wrong piece or move a piece to the wrong square. Check the display and move again. If you press a piece and the from square shows in the display, but you decide not to make that move, press that same square once again to cancel. Be careful not to make mistakes when the sound is off, as you will not be able to hear the error beeps. 2.4 Interrupting the Computers Search To interrupt the computer while it is thinking, press PLAY, and the computer will play the best move it has found so far. This can be most useful in games at a high level of play, when an exhaustive search for the best move can be quite time consuming. 2.5 Changing Sides with the Computer To change sides with the computer, press PLAY when it is your turn. The computer will make the next move for your side. Change sides as often as you wish!
3. LEVELS AND SPECIAL MODES
3.1 Levels of Play With 768 level settings to choose from (including the Extended Teach modes), you can learn and grow with this chess computer! As shown in the charts of playing levels in the following paragraphs, each level corresponds to one of the 64 board squares. The basic levels are categorized into 8 groups intended to suit users of different abilities: Fun Levels: A1 to A8. For the early beginner. A1 is easiest. Casual Levels: B1 to C8. For games not against the clock. Full range of difficulty from easy (B1) to extremely challenging (C8). When you first power up the computer B4 will be the selected level. Blitz: D1 to D8. Also known as Sudden Death. Game must be concluded within the selected time. Bronstein: E1 to E4. The game must be concluded within the selected time, which is then increased by an amount to compensate for each move. The compensation is the actual time used or the allowed time, whichever is shorter. Bonus Timer: E5 to E8. The game must be concluded within the selected time, which is increased by a prescribed amount to compensate for each move before the move is made. Tournament: F1 to F8. A certain number of moves must be made within the given amount of time. Fixed Depth: G1 to G8. Computer skill is limited by not being able to look ahead more than the selected number of moves. Tactical: H1 to H8. Computer skill is limited by not being able to look ahead more than the selected number of moves, and by not evaluating strategic advantage. When you set the level, bear in mind that when the computer has more time to think about its moves, it gets stronger and plays better just like a human player! Sharpen your chess skill as you beat the computer on each level, graduate to the next. Keep challenging yourself and learn more about the game!

2.8 Game Memory and Automatic Power Down You may interrupt a game by pressing GO/STOP to turn the computer off. The computer will remember your position for up to 600 hours (with fresh alkaline batteries). When you switch on again, continue where you left off! If you do not press a key or make a move within about 20 minutes when the computer is not thinking, the computer will switch off to conserve power, and will retain the game in memory. Press GO/STOP to resume the unfinished game. 2.9 Openings Library At the beginning of a game, the computers reply is usually instantaneous because the computer is playing moves which are stored in its openings

library. If the current board position is in its openings library, the computer plays a response to that position from its collection of moves, instead of thinking about the move.
3.2 Fun Levels Selection of any of the squares from A1 to A8 will give you the fun levels. In this range the computer does not make an exhaustive search for the best available move. It disregards scores, and in addition the program makes use of randomizers which cause the computer to occasionally make a move that is not the best of those it has found. This introduces an interesting variability in the computers responses, and sometimes it will seem to make quite human errors of judgement. A1 is the lowest skill level, and A8 is somewhat higher. 3.3 Casual Levels When casual levels are selected, you are controlling the skill level of the computer by limiting the average amount of time it has to select its move. As the skill level is increased, the computer will think ahead progressively more deeply, and as a consequence, play a more skillful game. When one of these levels is selected from the B or C files of squares, the display will alternate every second between the level selection and the average response line of the computer. Your choice is shown below:

L:c8/15:00 3.4 Blitz Levels The levels in the D file of squares are the Blitz levels. If you wish to play speed chess, or instant death, you can select from a range of times which are allowed for the game to be completed. You may choose between a 5 minute pressure cooker of a game to a more relaxed 11/2 hours. When you select one of these squares, the display will alternate every second between the name of the square you have selected, and the corresponding time limit for the game.
3.7 Tournament Levels The file of F squares provides 8 tournament levels. When one of these is selected, you and the computer are each required to make a prescribed number of moves within a given amount of time. For example, if you select F3 you will be required to make 40 moves within 2 hours under the Primary Time Control. If the game is not finished within that time, the Secondary Time Control period will begin, and you will be required to make 20 moves within 1 hour. And if this secondary period does not produce a result, it is repeated until a conclusion is reached. In accordance with tournament regulations, any time remaining at completion of the moves of the Primary Time Control is carried forward and added to the time allowed for the Secondary Time Control. For example, if you selected level F3 and completed the first 40 moves in just one hour, you would be allowed 2 hours for the next 20 moves. Surplus time, if there is any, is carried forward and accumulated in this way throughout the game. When you select one of these tournament levels, the display will cycle through three items of information, each of which shows for a second. For example, if square F4 is selected, the display will show: The selected square L:F4 and then. The number of moves in the Primary Time Control 40 and then. The duration of the Primary Time Control 2:00

Teach mode is set at previ ously selected level. LEVEL, Square, Starting position of selected Piece Symbol, LEVEL Teach mode is set at new level LEVEL, Piece Symbol, New level is set, previous Square, LEVEL Teach mode selection canceled, existing game retained To select Teach mode, press LEVEL. The display will show the skill level, as indicated by the equivalent chess board square, alternating with the level details. To select a Teach mode press the one or two appropriate Piece Symbol keys (%, $, #, @ or !) that you want to use. The display will then show the selected pieces. For example, if you wish to play with Kings, Bishops, Knights, and Pawns, after pressing LEVEL, you will press and # and @. The display will show your selection. Then press LEVEL to exit Level mode and enter your selection into the computer and begin your game. Since the King is always required for the game, you do not need to select this piece for the Teach mode, and in fact pressing & is the way you select a normal, 32 piece game.
Note that NonAuto is automatically canceled whenever a teach mode is selected on the existing level mode.
The eleven teach modes and normal game are indicated by the following displays:

Teach Mode Display

Note the following, in relation to the Levels and Teach modes:
If NEW GAME is pressed during any game, the computer will quit the Teach mode and switch back to the standard (32 pieces), with the current level still in effect. If you press LEVEL and you then decide not to change the current playing level or Teach mode, simply press LEVEL again, and the current status will remain as it is. You may select a new level at any time during your turn. However, the clock will be reset. If you press more than 2 Piece Symbol keys during a Teach mode selection, only the last 2 symbol selections will be valid when you exit Level Mode. If you accidentally press any piece symbol key in Level mode, you will lose the current game after exiting Level mode. To continue with the current game, press the square corresponding to the current level of play, before exiting Level mode. However, the clock will have been reset.) 3.11 Selecting Levels and Teach Modes Press LEVEL to enter Level mode, and the current level is displayed (eg Level A3 shows as L:A3 alternating with Fun3, which is the level selected by pressing board square A3). To change the level, simply press a board square, and the new level alternating with the level details will show in the display. Press LEVEL again to exit Level mode.
