making. Press the FWD key repeatedly to see the rest of the
moves in this line of play, as noted below. The principal
variation is shown to a maximum depth of four ply, or four
individual moves. The BACK key can be used to back up
and see previous displays again.
• Predicted line of play: 1st move.
• Predicted line of play: 2nd move.
• Predicted line of play: 3rd move.
• Predicted line of play: 4th move.
Since the first move of the predicted line of play is the
move the computer assumes you will make, you can also
consider this move as a hint! So—whenever you need help,
press HINT/INFO on your turn! For details, see Section 2.5.
6.2 Search Information
Press HINT/INFO a second time to get information on
the computer’s search. Use the FWD key to cycle through
the four displays listed below. The BACK key can be used to
back up and see previous displays again.
• Numerical evaluation of the current position, based on a
pawn being worth 1.0 points. A positive number indicates
that White is ahead.
Note that this score is not valid on
the Problem Solving Levels or Tactical Levels, since a
different search method is used.
• Two numbers. The first is the current search depth, or
the number of individual moves the computer is looking
ahead. The second is the number of moves the com-
puter has examined so far.
• The move currently being evaluated.
• The search speed, or number of positions (nodes) being
searched every second. Watch as this number changes!
6.3 Chess Clocks
Press HINT/INFO a third time to gain access to chess
clock information. Use the FWD key to cycle through all the
clock displays, as described below. The BACK key can be
used to back up and see previous displays again.
• Time since the last move was executed.
• Total elapsed time for White.
• Total elapsed time for Black.
• Remaining time for White
(Speed Chess/Tournament
Levels only).
• Remaining time for Black
(Speed Chess/Tournament
Levels only).
The chess clocks keep track of the time for both sides.
The clocks stop whenever you take back a move, check
level settings, select options, verify or set up a position, or
turn the computer off. In all of these cases, however, the
times are retained in memory, and the clocks resume as
soon as play is continued. Whenever you change the playing
level or press YES/

6.4 Move Count/Game Moves
Press HINT/INFO a fourth time to show the move num-
ber in the game so far. You can then use the BACK key to
cycle back through the moves of your game (up to 64 indi-
vidual moves). The FWD key can also be used to go forward
again at any point and see all the moves. This gives you an
opportunity to go back and write down the moves (up to the
last 64 individual moves) of a game that turns out to be
unexpectedly great!
• Move number in game so far.
• Moves of the current game.
