2.2 Chess Clocks
A built-in chess clock keeps track of the time for your (i.e.
not the computer’s) side, with a four-digit display showing the
total elapsed time for you. If you change sides by pressing
PLAY, the clock will keep track of the side you are currently
playing. After entering the computer’s move, the display
shows the indication for your side to move for about one
second to show that it is your turn. It then switches to show
your total elapsed time (until any key or square is pressed).
After you make your move, the display immediately switches
to show “
Co:
”, indicating the computer is thinking and that
the clock has stopped.
For the first hour of the game, the display will show
MINUTES:SECONDS, with a steady colon. If the total
elapsed time exceeds one hour, the display will show
MINUTES:SECONDS of the next hour. Note that the clock
stops whenever you have completed the allowable number of
take-backs of a move, you verify or change the level, verify
the board, or turn the computer off. Also note that when your
King is in check, the display shows check instead of the
chess clock. In each of these cases, however, the times are
retained in memory, and the clock resumes when play is
continued.
The chess clock can be switched off by pressing CLOCK
when it is your turn to move. The computer will beep and the
side to move will be displayed instead of the clock. Press
CLOCK again to switch on the clock and it will resume.
2.3 Capturing and Special Moves
Captures: To capture, press down lightly on the piece
you want to move, take the captured piece off the board, and
