Game-Ending Messages
LCD Chess will announce mate in
two (“MAtE2”) and mate in three

Black king in the middle give you
practice in checkmating the Black
king.

Also use it to enter game results for
a new rating if the ‘O’symbol is on,

use your LCD Chess to solve prob-
lems given in books and maga-
zines.

The first four levels (1, 2, 3 and 4)
are beginner levels and take
approximately 4, 8, 12 and 16 sec-
onds per move, respectively. Level
5 is a fixed 1-ply (one-half move)
search. Levels 6 through 72 take
about 1 second per level number, so
level 6 will average about 6 sec-
onds per move. The amount of time
taken will vary depending on the
position, the stage of the game, and
whether or not the FAST level
option is on. (See “Options,” pages
4 & 5.)
“RAND”: Allows the computer to
randomly choose between two
good moves so that you get to prac-
tice and play against different
responses. Press the NEXT PIECE
key to turn RANDom on or off. Or
press the MODE key.
Now play a move. If your move is
not the correct opening move, an
error buzz will sound. To learn the
correct move press HINT. When
the computer comes back with its
move, you will briefly see the word
“OPEN” on the screen if you have
another opening move to make. If
the word “OPEN” does not appear,
you may continue normal play. You
have completed the training for that
opening line.

Auto Play
If you would like to watch the com-
puter finish a game for you auto-
matically, push the MODE key,
then press OPTIONS, until the
option “PLAYR” is showing. Use
the LAST PIECE key to change the
number of players to zero. Press
MODE to exit the OPTIONS
mode. Now press the MOVE key
and watch the game play itself. You
may stop auto play at any time by
pressing the MOVE key. Doing so
will set the number of players back
to one.
When a “+” appears on the screen,
it is a reminder that you are in
check. When an “O” appears on the
screen, the game you are playing
can be rated. When an "=" appears,
it indicates you are in two- player
mode. And lastly when an “!”
appears on the screen, you are
being warned that one of your
pieces is threatened with capture.
(This is similar to the friendly "en
garde" warning sometimes used by
human players when they are
attacking an opponent’s queen.)
Level 73 is an infinite level. LCD
Chess will take as long to move as
you want it to, or until it finds a
mate position in its search. Level
73 is good for problem solving
(like the MATE problems available
under OPTIONS), or it can be used
to play against. When you are tired
of waiting, press the MOVE key
while the computer is thinking, and
the computer will stop thinking and
play the best move it’s found so far.
Computers can
sometimes "lock up"
due to static dis-
charge or other elec-
trical disturbances. If
this should happen,
use a slim, pointed
object to press the
