Since these Self-Adaptive Weak Levels are meant espe-

cially for beginners, however, here the computer will set its

playing strength to a deliberately weakened setting of about –

350 ELO on the lowest level (H1). On the other end, Level H8

matches the player’s strength by putting the ELO difference

at zero. As you play, the computer will try to keep this differ-

ence constant. That is, if you play badly, the computer will not

play well either—but it will fight to win back material it has

lost to you, if necessary. On the other hand, if you play stron-

ger, the computer will also play stronger. Work your way up,

learning as you go!

4. INFO MODE: WATCH THE COMPUTER THINK!

Imagine this: You’re playing chess against a friend, and

it’s his move. You’d love to know what move he’s thinking

about, and you’d really like to get his opinion of the board

position. But, of course, you won’t ask—because that’s just

not done!

Well, guess what—when you play against this

chess computer, you can ask anything you want,

and you’ll

get all the answers!

In fact, you can get an incredible amount

of information about the computer’s thought process. On

request, it will show you the move it’s 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, you’ll see the information displays change as the

computer considers different moves and searches deeper!

See “INFO MODE AT A GLANCE!” for a chart summa-

rizing all the Info Mode displays.

Game information is divided into four groups, and pressing

INFO cycles from one group to another. The BLACK/> and

</WHITE keys can be used to cycle forward and backward

respectively the displays within each of the groups. Press

CLEAR to exit Info Mode and go back to showing the normal

chess clock.

After learning about Info Mode, take a look at Section 5.3

for a description of the Rotating Display feature. Selecting

this feature makes the computer automatically cycle through

the requested information in one-second intervals every time

it thinks about its move—you can actually watch the com-

puter

think out loud!

Whenever requested information is not available, the

display will show dashes (–––––).

4.1 Principal Variation

Press INFO the first time to get information on the princi-

pal variation (the predicted line of play, or the sequence of

moves the computer thinks will be made). The first display

you will see is the move the computer is currently thinking of

making.

Notice that the move is shown in the display, and the

lights for the from and to squares for that move also flash

alternately.

This principal variation is shown to a maximum

depth of six individual moves. Press BLACK/> repeatedly

to cycle forwards all the moves:

• Move 1 (predicted line of play)

• Move 2 (predicted line of play)

• Move 3 (predicted line of play)

• Move 4 (predicted line of play)

• Move 5 (predicted line of play)

• Move 6 (predicted line of play)

Press </WHITE to cycle backwards and see previous

displays again. Press CLEAR to return to the normal clock

display.

Since the first move of the predicted line of play is the

move the computer assumes you will make, you can also

consider this move as a hint! So—whenever you need help,

press INFO on your turn!

4.2 Search Information

Press INFO a second time to get information on the

computer’s search! Press BLACK/> repeatedly to cycle

forwards these four displays:

• Evaluation of the current position (based on a pawn being

worth 1.0 points; a positive number indicates White is

ahead)

• Two numbers: The first is the current search depth, or the

number of individual moves the computer is looking

ahead; the second is the number of moves the computer

has examined so far

• The move currently being considered

• The search speed, or number of positions (nodes) being

searched every second

Press </WHITE to cycle backwards and see previous

displays again. Press CLEAR to return to the normal clock

display.

4.3 Chess Clock Information

Press INFO a third time for chess clock information. The

chess clocks keep track of the time for both sides. Press

BLACK/> repeatedly to cycle forwards the clock displays:

• Elapsed time since the last move was made

• Total elapsed time for White

• Total elapsed time for Black
