Excalibur 712 Operating Manual page 9

When an 'O' appears on the display, the
game you are playing can be rated. Since
the game you are playing is rated, you
cannot ask for a HINT, nor TAKEBACK
a bad move, nor use SETUP to improve
your position. You also cannot use the
NEW GAME key to start over during a
rated game.
These conditions attempt to allow you to
experience what it is like to play a game
against an opponent in a rated tourna-
ment. In rated tournaments a chess clock
is always used, so that you play your
moves within agreed upon time limits.
IVAN has the chess clock built in to it.
If you attempt to use the HINT, SETUP,
TAKEBACK, or NEW GAME keys dur-
ing your rated game, IVAN will ask
"ARE YOU SURE", and say what result
(draw, win, or loss) will be scored if you
press the YES key.
During a rated game if you are winning
by 9.0 or more points and want LCD
Chess to resign, press MODE then NEW
GAME. IVAN will say "ARE YOU
SURE I LOSE". IVAN will then wait for
you to press YES.
Using Setup Mode
At any time during a game when it is your
move, you may change the position on
the board by adding a piece, removing a
piece, or changing any of the pieces—for
example, from a queen to a knight.
Removing A Piece
Press the SETUP key. Then on the large
sensory board, press the square the piece
is on until the square on your display is
empty. Press CLEAR to continue the
game.
Adding or Changing a Piece
Press the SETUP key. Next press the key
that indictaes the type of piece you want
to place on the board. Then on the large
sensory board, press the square on the
sensory board until the piece appears as
the correct color on your display board.
Press CLEAR to continue the game.
Setting Up Special Positions
This is another terrific feature that allows
you to solve problems that you see in
magazines or newspapers, or that you
make up yourself. It also allows you to
enter game positions you want to play, or
that you want IVAN to look at, perhaps
using the Infinite Search level.
Normally, it is easier to start from an
empty board to set up such problems. So
first, press the OPTIONS key repeatedly
until CLRBR CLRBR (clear board) is displayed.
Now press the SETUP key. You'll see
that your display board is automatically
cleared.
On the large sensory board, press the
square the White king is on. Next press
the square the Black king is on once to
place a White king there, and then again
to change the White king to a Black king.
Next, pick out another piece in the prob-
lem or position you want to set up, and
press the appropriate piece key to the left
of the display. Then press the square on
the sensory board where this piece should
stand. Press the square repeatedly until
the piece appears in the right color on
your display.
Follow this procedure until all the pieces
in the problem or position are completely
set up.
Make sure that IVAN knows which color
is to move. You may change the color of
