Please note that

nience, to turn all the opening rule options on or off.
b. Individual Opening Rules
You also have the option of instructing the computer to
turn on only one opening rule or a specific combination of
rules. This feature allows you to study certain chess rules in
depth. To do this, simply turn the rules on and off individually.
Refer to the Option Mode Chart for a list of all the individual
rules, along with their ON/OFF displays. Note that some of
the displays include identifying icons.
The individual Opening Rules choices include such rules
as moving Knights before Bishops, avoiding early Queen
moves, castling early in the game, gaining control of the
center, and many others. For a complete list, refer to the
Option Mode Chart.
5.4 Rotating Display Options
IMPORTANT: The Rotating Display feature is only acti-
vated WHILE THE COMPUTER IS THINKING.
See “OPTION MODE: A COMPLETE OVERVIEW” for
a chart showing all the Rotating Display Options.
Press OPTION four times to select the Rotating Dis-
play Options. Then, use the FWD and BACK keys to select
the options you want to see rotated. Press YES/
?
?
?
?
?
to turn
these options ON or OFF.
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 6 (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 approximately
one-second increments. You may turn on any or all of the
Rotating Display options, as desired.
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:d
= the computer’s search depth and number of
moves examined so far in the game.
•
+rd:E
= an evaluation of the current position.
•
+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 full details
on exactly how to interpret the displays, go on to Section 6!
6. GAME INFORMATION
In a normal game of chess, you would never ask your
opponent what move he was considering, nor would you ask
his evaluation of the current position. However, when you
play chess against this computer, you can do exactly that! In
fact, you can gather a wealth of information about the
computer’s thought process—and studying this information
can help you learn more about chess!
Using Info Mode
See “AN OUTLINE OF INFO MODE” for a chart show-
ing how to use Info Mode, and a listing of all the Info
Mode options.
You may access game information at any time by using
Info Mode. If you do this while the computer is thinking, you
will see the information displays change as the computer
considers different moves and searches deeper.
Game information is divided into four groups, and press-
ing HINT/INFO cycles from one group to another. The FWD
and BACK keys can be used to cycle through the displays
within each of the groups. Press NO/X to exit Info Mode and
go back to showing the normal chess clock.
After familiarizing yourself with Info Mode, refer back to
Section 5.4 for a description of the user-programmable
Rotating Display feature. Selecting this feature causes the
computer to automatically cycle through the information
described below in approximately one-second intervals every
time it thinks about its move—you can actually watch the
computer “think out loud”!
Whenever requested information is not available, the
display will show a series of dashes (-----).
6.1 Principal Variation
Press HINT/INFO the first time to see the first move of
the principal variation (the line of predicted play). This first
move is the move the computer is currently considering
