Draw Messages
During the game, your LCD Chess will
display the word
drAU if a three-time
repetition of position occurs, or if there
has been no pawn moved and no
exchanges for 50 moves. When either of
these situation takes place, the rules of
chess state that a player can claim a draw.
If you wish, you can ignore the message
and continue the game. When a stalemate
is reached, the display will show
StAL.
Game-Ending Messages
LCD Chess will announce mate in two
(
MAtE2) and mate in three (MAtE3).
It will also display +MAtE when exe-
cuting a checkmate or when you check-
mate LCD Chess.
Screen Symbols
When a ‘ +’ appears on the screen, it is a
reminder that you are in check. When an
‘=’ appears, it indicates you are in two
human player mode. And lastly when an
‘!’ appears on the screen, you are being
warned that one of your pieces is threat-
ened with capture. (This is similar to the
friendly "en garde" warning sometimes
used by human players when they are
attacking an opponent’s queen.) To see
which of your pieces is threatened, press
the OPTIONS key.
Auto Play
If you would like to watch the computer
finish a game for you automatically, press
the OPTIONS key repeatedly until the
option
PLYr is showing. Use the + but-
ton to change the number of players to
zero. Press CLEAR to exit the OPTIONS
mode. Now press the GO key twice and
watch the game play itself. You may stop
auto play at any time by pressing the GO
key. Doing so will set the number of play-
ers back to one.

return to normal play.
Now play a move. If your move is not the
correct opening move, an error buzz will
sound. To learn the correct move press

pleted the training for that opening line.
