in book of openings. When you turn the book off, the computer is forced to take time to think of its moves from the very beginning of the game, rather than using moves contained in its memory. For more details on openings, see Section 2.7. If you turn the book completely off, all other book options are also automatically disabled.

5.3 Rotating Display Options (Squares A3-H3)

IMPORTANT: The Rotating Display feature is only activated

WHILE THE COMPUTER IS THINKING.

Normally, the display shows the time for the player to move. However, the computer can also display other information, as noted in Section 4

For more details, see Section 5.1.

f. Complete Book (Square F2) On:+bk:? Off:-bk:?

Turning on the Complete Book option gives the computer the free- dom to choose any move from its built-in book of openings, so you’ll see a greater variety of opening lines being played. If this option is selected, the Passive, Active, and Tournament Book options are disabled.

With this option on, you may see the computer make some question- able moves. This is because its built-in book of openings must contain responses to certain lines of play (even questionable lines), in case they are played. While the computer would not make these moves on its own, it needs to know how to respond to them in the best way. There- fore, when you turn on the Complete Book, the computer could poten- tially play one of these moves.

g. Tournament Book (Square G2) On:+bk:t Off:-bk:t

When you turn the Tournament Book option on, the computer is forced to always select the best possible line of play in every opening. While this results in the best chess play, it also narrows down the computer’s choice of moves by limiting its available book lines. If this option is selected, the Active and Passive Book options are disabled.

h. Book On/Off (Square H2) On:+bOOk Off:-bOOk

Set this option to -BOOKto completely lock out the computer’s built-

(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 one-second increments. You may turn on any or all of the Rotating Display options, as desired.

Press OPTION three times to select the Rotating Display Op- tions. Then use the BLACK/> and WHITE/< keys to select the options you want to see rotated in the display. The options are de- scribed below and summarized in the Option Mode Chart in this sec- tion. 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 automati- cally 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 (– – – – –).
