GUIDE
INTRODUCTION
We'd
like
to
welcome
you to the
exciting
world
of
computer
chess!
Whether
you're
just
starting
to
learn
about
this
great
game
or
you're
already a seasoned
player,
using
your
new
chess
computer
will
give
you
the
opportunity
to
discover
so
much
more
about
chess
than
you
ever
thought
possible!
Take a look
through
this
manual
to get an
over-
view
of
your
computer's
capabilities—all
the
special
features
and
modes,
all the
unique
options
and
playing
levels.
And
take
advantage
of
them
over
time,
one by
one!
You'll
have
great
fun—and
you'll
never
look
at
chess
the
same
way
again!
Your
computer
knows
all the
rules
of
chess—and
it
will
never
cheat!
For
those
of you who
haven't
played
before,
we
have
included a brief
overview
of the
rules
to get you
started.
For
more
detailed
information,
why
not
visit
your
local
library,
where
you're
sure
to
find
lots
of
interest-
ing
chess
books!
1.
LET'S
GET
STARTED!
1.1
First,
Install
the
Batteries
Your
computer
runs
on
four
"AA"
(Type
AM3/R6)
batteries.
Insert
the
batteries
into
the
compartment
in the
base
of the
unit,
making
sure
to
observe
the
correct
polarity.
Use
fresh
alkaline
batteries
for
longer
battery
life!
Turn
the'computer
on by
pressing
GO/STOP,
and a
beep
will
signal
that
the
game
is
ready
to
play.
If the
computer
fails
to
respond
(static
Page 5
discharge
may
cause
it to
lock
up),
use a
paper
clip
or
another
sharp
object
to
press
down
into
the
hole
marked
ACL in the
base
of the
unit
for
at
least
one
second.
This
will
reset
the
computer.
Tip:
To
conserve
energy
and
extend
battery
life,
turn
on the
Auto
Power
Down
option
(see
Section
5.1).
1.2
Ready
to
Play?
Here's
How to
Move!
Okay,
now
it's
time
to
start a game!
It's
so
easy—just
follow
these
steps:
a.
Press
GO/STOP
to
turn
the
computer
on, if you
haven't
already
done
so.
b.
Press
NEW
GAME
to
reset
the
computer
for a new
game
of
chess.
Set up the
pieces
in
their
starting
positions,
with
the
White
pieces
nearest
to
you,
as
shown
in the
Quick
Start.
c.
To
make a move,
lightly
press
down
on the
piece
you
want
to
move
until
you
hear a beep
and two
board
lights
turn
on to
indicate
that
square.
The
sensory
board
will
recognize
your
piece
automatically.
Don't
believe
it?
Just
look
at the
display
window,
which
is
suddenly
full
of
information—it
shows
your
piece,
along
with
the
piece
color
and the
square
you
just
pressed!
d.
Take
that
piece
and
gently
press
it
down
into
the
hole
of the
square
you are
moving
to.
You'll
hear a second
beep
as the
computer
confirms
your
move.
That's
it—you've
just
made
your
first
move
of the
game!
Next,
it's
Black's
turn—and
the
computer
will
make
its
first
move.
You'll
notice
that
the
computer
often
moves
instantly
at the
beginning
of a game,
instead
of
taking
time
to
think.
This
is
because
it is
playing
from
memory,
using a built-in
"book"
of
opening
moves
(for
more
information,
see
Section
2.7).
1.3
Now
It's
the
Computer's
Turn
When
the
computer
makes
its
move,
it
beeps
and
turns
on two
board
lights
indicating
the
square
of the
piece
it
wants
to
move.
It
also
shows
its
full
move
in the
display
window.
Check
it
out—you'll
see the
from
and to
squares
of the
computer's
move,
along
with
the
color
and
type
of
piece
it is
moving.
Notice
that
the
from
square
is
flashing
in the
display.
Press
the
indicated
piece
down
on the
from
square
until
you
hear
a
beep.
The to
square
is now
flashing
in the
display—move
that
same
piece
to the
indicated
to
square
and
press
it
down
to
complete
the
MAKING
THE
COMPUTER'S
MOVE:
AN
EXAMPLE!
After
the
computer
moves,
it's
up to you to
make
its
move
on the
board!
Here,
the
display
indicates
the
computer
wants
to
move
its
Black
pawn
(•
A)
from
d7 to d5.
Pick
up the d7
pawn
(indicated
by
the
board
lights)
and
press
it
down
lightly
into
the
hole
on
Square
d7. The
board
lights
now
point
to
Square
d5.
Press
the
pawn
down
into
the
hole
on
Square
d5 to
complete
the
computer's
move.
Now
it's
your
turn
again!

And
it's
your
turn
again...
See
"MAKING
THE
COMPUTER'S
MOVE:
AN
EXAMPLE!"
for
a
how-to
illustration!
By
the
way,
while
you're
thinking
about
your
next
move,
notice
that
the
chess
piece
symbols
are
displayed,
one by
one,
counting
"up"
from
pawn
to
King.
This
means
the
built-in
chess
clock
is in
normal
mode,
counting
your
elapsed
time.
If the
Countdown
Clock
is
activated,
as
described
in
Section
5.1,
the
displayed
symbols
will
reverse
direction.
You'll
find
details
on all the
chess
clock
features
in
Section
4.3!
1.4
Change
Your
Mind?
Take
Back!
When
you're
playing
chess
against
this
computer,
nothing
is
"set
in
stone"—you,can
change
your
mind
or
decide
to
play a different
move
whenever
you
want!
When
it's
your
turn
to
move,
simply
press
TAKE
BACK.
The
display
shows
the
move
to be
taken
back,
with
the
original
Page 6
to
square
flashing
and
indicated
by
board
lights.
Press
the
piece
down
gently
on the
indicated
square,
and the
computer
shows
you
where
that
piece
came
from
by
flashing
that
display
and
using
board
lights
to
point
to
that
square.
Press
the
piece
down
on the
from
square
to
complete
the
take-back.
Repeat
this
as
often
as
you'd
like,
taking
back
up to 50
individual
moves
(or 25
moves
for
each
side).
To
continue
playing
at
any
point,
just
make
another
move
on the
board!
After
taking
back a capture,
the
computer
will
make
sure
your
board
is
still
set up
correctly
by
reminding
you to put the
captured
piece
back
on
the
board!
It
displays
the
piece
symbol,
the
location,
and a
"+"
symbol,
and
turns
on the
board
lights
for
that
square.
Put the
indicated
piece
back
on the
board
and
press
that
square
to
complete
the
take-
back.
1.5
Game
Over?
Why Not
Play
Again!
Whenever
you
finish a game
(or if you
give
up on
your
current
game),
it's
easy
to
start
over
again!
Reset
the
computer
to
start
another
game
by
pressing
NEW
GAME,
and a
series
of
beeps
tells
you the
computer
is
ready.
The
same
playing
level
will
be in
effect,
but you can
change
it if
you'd
like,
as
explained
in
Section
3.
IMPORTANT:
Pressing
NEW
GAME
clears
your
current
game
from
the
computer's
memory—be
careful
not to
press
this
key by
mistake!
1.6
Too
Easy/Hard?
Change
the
Level!
When
you
first
turn
your
computer
on,
it's
automatically
set to
Normal
Playing
Level
A4
(five
seconds a move).
However,
you
have
64
different
levels
to
choose
from—you'll
want
to try
them
all
out!
For
descriptions
of
the
playing
levels
and how to
change
levels,
see
Section
3.

EXPLORE
2.1
Whose
Move?
Check
the
Display!
When
the
computer
plays
Black,
it
flashes a black

in the
display
while
it is
thinking.
After
it has
moved, a white
square
shows
that
it
is now
White's
turn
to

You can
tell
at a

thinking,
and
which
side
is to
move!

CHOOSING A LEVEL?
SOME
TIPS
FOR
YOU!
• Are you a
beginning
player?
You
have
lots
of
choices!
Check
out the Fun
Levels,
the
lower
Training
Levels,
or the
Self-Adaptive
Weak
Levels.
These
levels
all
restrict
the
computer's
search
depth
in
different
ways,
resulting
in
weaker
play
and
giving
you the
chance
to
learn
more
about
the
game
and
perhaps
even
beat
the
computer
occasionally!
• Are you an
intermediate
or
more
advanced
player?
Try the
Normal,
Training,
or
Tournament
Levels.
The
Normal
Levels
range
from
easy
all the way up to a
difficult
10-minute
re-
sponse
time,
and the
Tournament
Levels
are
extremely
challenging.
And
don't
forget
to try the
Blitz
Levels
for
some
fast
and
exciting
games
of
Speed
Chess!
By the
way,
for
Tournament
and
Blitz
Games,
you can
activate
the
built-in
Bronstein
Clock,
as
you'll
see in
Section
5.4!
•
Want
to
experiment?
Use the
Mate
Search
Levels
to
solve
problems
up to
mate
in
eight—try
searching
from a position
in
one of
your
own
games,
or set up an
actual
mate
problem.
Choose
the
Infinite
Level
to
have
the
computer
analyze
complicated
positions
for
hours
or
even
days!
rerrtove
the
captured
piece
from
the
board,
and
press
your
piece
down
on
the
square
of the
captured
piece.
Captures
are
displayed
as in
ESsFH.
En
Passant
Captures:
In
this
type
of
capture,
the
computer
reminds
you
to
remove
the
captured
pawn
by
displaying
the
pawn's
position,
along
with a minus
sign,
and
using
two
board
lights
to
indicate
that
square.
Press
down
on the
captured
pawn
before
removing
it
from
the
board.
Castling:
The
computer
automatically
recognizes
castling
after
the
King
is
moved.
After
you
have
pressed
the
King
down
on its

to
squares,
the
computer
uses
the
display
and
board
lights
to

immediately,
and
begins
thinking
about
its
next
move.
Remember
to
change
your
piece
on
the
board!
When
the
computer
promotes a pawn,
the
display
shows
both
the
pawn
and the
promoted
piece.
Don't
forget
to
replace
the
computer's
pawn
with
its new
piece.
2.3
Illegal
Moves
Your
computer
will
never
accept
an
illegal
move!
If you try to
make
one,
you'll
hear
a low
double
beep,
and the
board
lights
and
display
will
simply
continue
to
show
the

came
from.
Either
move
that
same
piece
to
another

back
down
on
the
original
from
square
and
move a different
piece.
If
you
don't
make
the
computer's
move
correctly,
you'll
also
get an
error
beep.
This
means
you are
moving
the
wrong
piece,
or
moving
the
computer's
piece
to the
wrong
square.
If the
computer
wants
to
move
its
pawn
from
C7 to C5, for
example,
and you
press
down
on C7 and
then
C6,
the
display
shows :CS
briefly,
pointing
out
your
error.
The
display
then
returns
to
showing
the
move
again
(C1-CS),
and the
computer
expects
you to
press
C5 to
complete
its
move.
If
you
press
down
on a
piece
and the
from
square
is
displayed,
but
you
decide
not to
make
that
move,
simply
press
down
on
that
same
square
again
to
cancel.
Then
make
another
move.
If you
change
your
mind
after
entering
your
whole
move,
take
the
move
back
as
described
in
Section
1.4.
2.4
Check,
Mate,
and
Draw
When a King
is in
check,
the
computer
first
displays
its
move
as
usual.
After
the
move
is
made,
CHECt'
flashes
in the
display
for a few
seconds,
along
with
the
checking
move.
The
display
then
goes
back
to
showing
the
clock.
If
the
computer
discovers a forced
mate
against
its
opponent,
it
first
displays
its
move
as
usual.
After
the
move
has
been
made
on the
board,
the
computer
flashes a mate
announcement
along
with
the
move
for
several
seconds
(e.g., + m
5 for a
mate
in two
moves).
The
display
then
goes
back
to
showing
the
clock.
When a game
ends
in
checkmate,
the
display
flashes
lilfitE
(along
with
the
mating
move)
for a
short
time
after
the
move
is
made.
The
display
then
goes
back
to
showing
the
clock.
The
computer
recognizes
draws
by
stalemate,
three-fold
repetition,
and the
50-move
rule
and
insufficient
material.
After a draw
has oc-
curred,
the
display
flashes
End,End:3,£nd:SO,or
£nd: ln,(along
with
the
drawing
move)
for a
brief
time
after
the
move
has
been
made.
The
display
then
goes
back
to
showing
the
clock.
2.5
Interrupting
the
Computer's
Search
Think
the
computer
is
taking
too
long
to
move?
You can
interrupt
it
any
time!
Simply
press
ENTER
while
the
computer
is
thinking,
and it
will
stop
and
play
the
best
move
it has
found
so
far.
This
feature
can be
handy
on the
higher
levels,
where
the
computer
can
take a long
time
to
move,
and on the
Infinite
Level,
where
the
computer
thinks
indefinitely
unless
you
stop
it.
On
the
Mate
Search
Levels,
pressing
ENTER
won't
force
the
com-
puter
to
make a move.
Instead,
the
computer
will
sound
an
error
beep
and
display
-----to
indicate
that
it was
interrupted
before
it
found
a
mate.
To
continue
play,
switch
to
another
level.
2.6
Changing
Sides
with
the
Computer
To
change
sides
with
the
computer,
simply
press
ENTER
when
it's
your
turn—and
the
computer
will
make
the
next
move
for
your
side.
Change
sides
as
often
as you
wish!
Noted
that
if you
press
ENTER
at a new
game,
computer
will
play
White
from
top
(see
also
Section
5.1).
2.7
Built-in
Openings
At
the
beginning
of a
game,
the
computer
will
often
move
instantly
on
many
levels.
This
is
because
it is
playing
from
memory,
using
its own
built-in
"book"
of
opening
chess
moves.
This
book
contains
thousands
of
positions,
including
most
major
openings
and
many
positions
from
grandmaster
play.
If the
current
board
position
is in its
book,
the
com-
puter
plays a response
to
that
position
automatically,
instead
of
having
to
think
about
the
move!
A
special
feature
of
this
computer's
opening
book
is its
ability
to
handle
transpositions. A transposition
occurs
when a position
reached
by a certain
set of
moves
can
also
be
reached
when
those
same
moves
occur
in a
different
order.
The
computer's
integrated
Automatic
Trans-
position
Manager
handles
these
cases
with
ease!
Also
included
is a
unique
user-selectable
book
feature,
which
lets
Page 8
you
choose
from
different
types
of
opening
books,
or
even
turn
the
book
off,
if
desired.
For
complete
details,
see
Section
5.2.
2.8
Thinking
on the
Opponent's
Time
As
you
play,
you may
notice
that
the
computer
sometimes
replies
to
your
moves
immediately,
even
in the
middle
of
games
played
on the
higher
levels.
This
is
because
the
computer
thinks
on
your
time,
using
the
time
you are
taking
for
your
move
to
think
ahead
and
plan
its own
strategies.
It
tries
to
guess
the
move
you are
likely
to
make,
and
then
calculates
its
responses
for
that
particular
move
while
you are
still
thinking.
If the
computer
has
guessed
right,
there's
no
reason
for it to
keep
on
calculating—it
immediately
plays
the
move
it has
already
found!
To
disable
this
feature,
turn
on the
Easy
Mode
option,
as
described
in
Section
5.2.
2.9
Game
Memory
Press
GO/STOP
at any
time
to
interrupt a game.
Play
is
then
sus-
pended,
and the
computer
stores
your
current
game
in
memory
(up to
50
individual
moves).
When
you
switch
back
on
again,
you can
con-
tinue
right
where
you
left
off!
3. THE
PLAYING
LEVELS
Your
chess
computer
offers
64
different
levels
of
play!
When
you set
the
level,
keep
in
mind
that
when
the
computer
has
more
time
to
think
about
its
moves,
it
becomes
stronger
and
plays
better—just
like
a
human
chess
player!
For an
overview
of all the
levels,
refer
to the
Level
Chart.
The
levels
are
also
described
individually
in
this
section.
Setting a Playing
Level
See
"USE
THIS
CHART
TO
SELECT A PLAYING
LEVEL!"
for
an
illustrated
look
at how to set a
level
and a
chart
showing
all
the
levels
at a
glance.
_____________
There
are two
methods
of
setting
levels—by
using
the
game
keys
or
pressing
the
board
squares.
Whichever
method
you
use,
always
press
LEVEL
first
to
enter
Level
Mode,
and the
computer
will
display
the
current
playing
level.
When
you
enter
Level
Mode
the
first
time,
the
computer
is set on
Normal
Playing
Level
A4
(with
an
average
response
time
of
five
seconds a move),
and the
display
shows L 0:OS.
«
To
select a level
by
using
game
keys:
After
entering
Level
Mode
by
pressing
LEVEL,
change
levels
one at a
time
by
using
the
BLACK/+
and
WHITE/-
keys.
As a
shortcut,
press
LEVEL
repeat-
edly
to
skip
over
eight
levels
at a
time.
When
the
display
shows
your
desired
level,
press
ENTER
to
enter
your
new
level
into
the
computer
and
exit
Level
Mode.
• To
select a level
by
pressing
board
squares:
As
shown
in the
Level
Chart,
each
of the 64
squares
corresponds
to one
level.
After
entering
Level
Mode
by
pressing
LEVEL,
take a chess
piece
and
press
the
desired
square
to
activate a level,
using
the
chart
as a
guide.
When
you
press
down
on
your
chosen
square
and
that
level
shows
in the
display,
press
ENTER
to
enter
your
new
level
into
the
computer
and
exit
Level
Mode.
Note
that
when
making
your
selection
via the
board
squares,
pressing
CLEAR
has the
same
effect
as
pressing
ENTER—it
enters
your
level
into
the
computer.
• To
verify
the
level
without
changing
it: If you
press
LEVEL
to
verify
the
level
but you
don't
want
to
actually
change
levels,
press
CLEAR.
This
returns
you to
normal
play
without
changing
the
level
or
clock
settings,
even
while
the
computer
is
thinking.
Other
important
points
to
remember
regarding
levels:
•
Changing
the
level
always
resets
the
chess
clocks.
• We
don't
recommend
changing
levels
while
the
computer
is
thinking,
since
the
clock
is
reset
and the
current
search
is
aborted.
If
you
must
do
this,
first
press
ENTER
to
abort
the
computer's
search,
and
make
its
move
on the
board.
Then,
take
back
the
computer's
move
and
change
the
level.
Finally,
press
ENTER
to
make
the
computer
start
thinking
on the new
level.

The
Tournament
Levels
require
you to
make a certain
number
of
moves
within a given
amount
of
time.
If a
player
exceeds
the
allotted
time
for a
given
number
of
moves,
the
computer
flashes
"time"
(t
!fl£)
along
with
the
elapsed
time,
to
show
that
the
game
is
over.
If you
wish,
you can
continue
to
play
even
after
the
time
has run
out.
If
you
choose a Tournament

you may
want
to set the

to
display
countdown
time
instead
of

When
game
time
runs
out,
the
countdown
clock
automatically
reverts

Speed
Chess
or
"Sudden

Levels),
you set the
total

game.
If

is
exceeded,
the
computer
flashes
"time"
(fc

along
with
the
elapsed
time,
to
show
that
the

is
over.
If
you
select a Blitz
Level,
you may
want
to set the

to
display
countdown
time
instead
of

When
game

runs
out,
the

automatically
reverts
back

Are
you a
novice
or
beginning
chess
player?
If so,
these
levels
are
especially
for
you!
Here,
the
computer restricts
its
search
so
that
it
deliberately
plays
weaker
and
gives
you a
better
chance
to
win!
The Fun
Levels
start
out
easy
and get a
little
harder
as you go. The
computer's
playing
strength
goes
up
gradually
from
Levels
E1 to
E6—
but
be
prepared
for
some
stiffer
competition
when
you
reach
Levels
E7
and
E8!
These
two
highest
Fun
Levels
represent a much
greater
jump
in
playing
strength,
and
you'll
notice
that
they're
quite
a bit
more
chal-
lenging.
Try out all the Fun
Levels—as
you
beat
each
one,
go on to the
next!
By the
time
you
reach
Levels
E7 and E8,
your
improved
chess
skills
should
make
them
much
easier
to
handle!

Selecting
one of
these

activates a special
Mate
Finder
Pro-
gram.
If you
have a position
where
there
may be a
mate
and you
would
like
the
computer
to
find
it, set the
computer
on one of the
Mate
Search
Levels.
Your
computer
can
solve
mates
in up to
eight
moves.
Mates
in
one to
five
are
usually found
quite
quickly,
whereas
solutions taking
six
to
eight
moves
may
take
quite
some
time.
If
there

the

it

On
the
Training
Levels,
the
computer's
search
depth
is
limited
to a
certain
number
of
moves,
as
shown
above.
As you
cycle
through
the
levels,
the
computer
displays
PL'd: # for
each
level. A "ply"
is an
indi-
vidual
move
(a
move
for
either
side),
and
"#"
is the
number
representing
the
search
depth.
For
example,
on
Level
G1,
the
computer
searches
to
a
depth
of one ply
(PL'd: I), and
thus
looks
ahead
only
one
individual
move.
On
this level,
therefore,
it
will
often
overlook a mate
in
one. This
produces
weaker
play,
giving
beginners a better
chance
of
beating
the
computer!

The
Self-Adaptive
Weak
Levels
are
perfect
for
players
who are
just
starting
out!
Here,
beginners
have
the
chance
to
interact
with
the
computer
on
eight
weakened
levels
of
varying
ELO
rating
strengths,
and the
computer's
strength
is
adjusted
to
match
that
of the
player.
Not
sure
what
an ELO
rating
is?
It's
a way of
measuring
chess
performance!
Chess
ratings
are
usually
four-digit
numbers,
with
stronger
players
having
higher
ratings.
Towards
the
upper
end of the
scale,
masters
rank
in
at
2200
and
above.
Just
for
your
information,
on
some
of its
stronger
levels,
your
computer
is
rated
at
over
2000
ELO!
Since
these
Self-Adaptive
Weak
Levels
are
meant
especially
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 difference 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
stronger,
the
computer
Page 12
will
also
play
stronger.
Work
your
way up!

THE

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

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

can
help
you
learn

On: + Co=ch
Off:-Co:ch
Selecting + Co:ch
turns
on
special
coaching
features
that
encourage
you
to
concentrate
on
your
strategic
planning!
In
Coach
Mode,
the
computer
looks
over
your
shoulder
while
you
play,
watching
what
you
do
and
helping
you
when
you
need
assistance!
In
this
unique
"Guardian
Angel"
capacity,
the
computer
will
warn
you
with a Capture
Alert
if you
are in
danger
of
losing a piece.
If one of
your
pieces
is
threatened
by a
lesser
valued
piece,
for
example,
the
computer
will
sound a series
of
warning
beeps
and
flash
the
board
lights
of the
threatened
piece
for a
few
seconds.
To
continue
the
game,
make
your
next
move
(or
take
back
your
last
move
and
make a different
one).
With
Coach
Mode
on, the
computer
will
also
sound a Tactical
Alert
if it
thinks
you
have
committed a blunder
and
your
move
is
about
to
lead
to
an
avoidable
material
loss.
It
does
this
by
sounding a series
of
warning
beeps
and
flashing
the
move
it
intends
to
make.
You can
either
enter
the
computer's
move,
or
take
back
your
own
move
and
make
another
one.

Notice
that
the

a.
Selective

(Square

The
program
in
this

computer
normally
uses a Selective

Search
algorithm.
This
allows
the
computer
to see
combinations that
would
otherwise
take
much
longer
to
compute.
Turning
this
option
off by
choosing
-SEi
makes
the
program
switch
to a
powerful
Brute
Force
algorithm.
This
search
method
minimizes
the
risk
of an
occasional
*
oversight.
Note
that
the
Mate
Search
Levels
always
use the
Brute
Force
method.
b.

which
prevents
the
computer
from
thinking

This
weakens
all
the
playing
levels
without
affecting
the
computer's
time
controls.
Normally,
as
described
in
Section
2.8,
the
computer
thinks
on
your
time,
using
the
time
you are
contemplating
your
next
move
to
think
ahead
and
plan
its
strategies.
This
is
part
of
what
makes
your
computer
such a tough

By
using
Easy

you
effectively

book
of
openings,
set
this

When
the
book
is
off,
the
computer
is
forced
to
take
time
to
think
of its
moves
from
the
beginning
of the
game,
rather
than
making
its
moves
from
memory.
For
details
on
openings,
see
Section
2.7.
If
you
turn
the
book
completely
off,
the
other
book
options
(described
below)
are
also
automatically
disabled.
e.
Full
Book
(Square

Turning
on the
Full
Book
option
gives
the
computer
the
freedom
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
Full
Book,
the
computer
could
potentially
play
one of
these
moves.
f.

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

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
decreases
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
+
bO: 10
option
will
give
you a
maximum
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
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
four
times
to
select
the
Bronstein
Clock
Mode.
Then
press
ENTER
repeatedly
