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 15 take
about 1 second per level number, so
level 10 will average about 10 sec-
onds per move. Levels 16 through
72 take about 2 seconds per level
number. 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 “Level Options,” page 6.)
Level 73 is an infinite level.
Electronic 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 solv-
ing (like the MATE problems avail-
able under OPTIONS), or it can be
used to play against. When you are
tired of waiting, press the GO key
while the computer is thinking, and
the computer will stop thinking and
play the best move it’s found so far.
Auto Play
If you would like to watch the
computer finish a game for you
automatically, press the 2nd key,
then press the PLAYER key repeat-
edly to change the number of play-
ers to zero. Press CLEAR and then
press the GO key twice and watch
the game play itself. You may stop
auto play at any time by pressing
the GO key, which will set the num-
ber of players back to one.
Replay Variation
You may automatically replay all the
moves saved by Electronic Chess for
undoing. If you would like to replay the
stored moves, first undo all the moves
by pressing the 2nd key, and then press
the PLAYER key repeatedly to change
the number of players to zero. Press
CLEAR and then press the UNDO key.
Now to replay the variation and return
to your original position, press the 2nd
key, then press the PLAYER key
repeatedly to change the number of
players to zero. Press CLEAR and then
press the GO key and watch the moves.
Electronic Chess will stop Auto Play
when it arrives at the original position.
