and then press it again to turn it

Changing the Play Level
Press the 2nd key and then the
LEVEL key to show the current
level number on the chess board.
If you wish to change the level,
repeated press the LEVEL key
until the desired level is shown.
Press the CLEAR key to return
to the current chess board position
and continue play. There are eight
levels of play. Each level (except
level 3) will have a fixed time for
LCD Keychain Chess to compute
its move. Level 3 is a 1 ply search
level. A ply is computer search
terminology for a half-move. On
level 3, LCD Keychain Chess will
always look at all of its possible
moves, but not look at what move
you will do in response.
Level 1: approximately 1 second
Level 2: approximately 3 seconds
Level 3: 1 PLY
Level 4: approximately 6 seconds

will now show the first training
position instead of the initial chess
board. The “=” ICON will turn on
to remind you that you can again
press the TRAIN key to select
the next training position. There
are eight training positions, so
when the last one is shown, LCD
Keychain Chess will cycle back
to the first training position. The
training positions with the black
king in the center of the board are
mate training positions.
