back to its default setting of OFF when you start a new game
or a teach mode game.

On:

+aPd

  Off:

-aPd

Auto Power Down option is a handy battery-saving feature.

With this option activated, the computer will automatically
turn itself off if no keypresses or moves are made for about
15 minutes. To continue the game where you left off, press
GO/STOP to turn the computer back on. 

Note that the com-

puter will not turn itself off while it is thinking about a move.

5.2 Rotating Display Options (Squares A3-H3)

Normally, the computer’s 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 one-
second increments. You may turn on any or all of the Rotat-
ing Display options, as desired.

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 computer’s 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 de-
creases as you think. On these levels, players often find
themselves running out of time towards the end of the
game—struggling 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.

Here’s an example: Let’s say you’re 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 maxi-

mum 10 seconds time compensation per move (added after
you make your move). Note that you can’t gain extra time or
increase overall thinking time by playing each move more

quickly, since:

• If you use 7 seconds to make your move, only 7 seconds

will be added back to your total remaining time, not 10
seconds.

• If you use 10 seconds or more to make your move, only

10 seconds will be added back to your total remaining
time.

Press OPTION three times to select the Bronstein

Clock Mode. Then press ENTER repeatedly to select your
desired Bronstein Clock setting, as described below:

6. TEACH MODE: LEARN ABOUT TACTICS!

The Extended Teach Modes offer a wonderful learning tool,

allowing you to study basic moves and master the tactics of
the individual chess pieces. For each Teach Mode game, the
only pieces on the board are Kings and the selected piece
type(s). This will help you concentrate on one piece at a time,
without losing focus and being distracted by other pieces on
the board! This feature is ideal for beginners or anyone
wanting to improve basic skills.

See “A LOOK AT THE TEACH MODES!” for a step-by-
step example of how to use this feature!

Using the Teach Modes

To enter Teach Mode, first press LEVEL, and the computer

will display the current playing level. If you want to change
the level, press a board square as described in Section 3. If
you don’t change the level, the current level will remain in
effect. When you are using any of the Teach Modes, the
computer’s playing strength will be determined by the level
