MULTI MOVE
If you want to use the computer as a monitor and referee while you play
against a friend, you can use the Multi Move Mode. This feature allows you
to enter moves for both black and white pieces. Simply press the MULTI
MOVE button to enter the mode. When you are in Multi Move the display
will show PLAY. Then proceed with your game. Should you or your
opponent make an illegal move, the computer will beep and or notify you of
your illegal move. The Hint feature does not work in this mode. But if you
do require assistance you can press the MOVE key and the computer will
make what it thinks is the best possible move. You can have the computer, by
pressing the MULTI MOVE button, allow you to enter your own book
opening line by making moves for both sides, and then by exiting this feature
you can begin to play your game. To exit Multi Move, just press Multi Move

VERIFYING POSITION
Whenever you think a piece is in the wrong position on the board, or if you
want to restore a previously saved position, VERIFY will tell you what Ivan
believes the position is. You may use the VERIFY button at any time, before
or during a game as long as it is your turn to move. Press the VERIFY button
and the display will show the symbol for white, the queen, and the location of
the white queen, if there is one. Press the button a second time and the
display will show the symbol for black, the queen symbol and the location of
the black queen. Proceed by pressing each of the piece symbol buttons and
the display will show the location of each piece. When you have finished
verifying the pieces, simply press the CLEAR key to exit the verification mode
and resume play.
DON’T KNOW WHAT TO DO? ASK FOR A HINT
If you do not know which move to make, or you think the computer might
have a better idea, you can ask Ivan for a hint. Press the HINT once and the
computer will display what it thinks you should do based on its previous
search. If you choose to accept the hint then make that move. If you choose
not to accept the hint and you want to make another move then simply press
CLEAR and make another move.
Pressing the HINT button twice this will cause the display to show you the
score of the position. The score is always displayed from the Ivan’s point of
view. A plus score is good for Ivan and a minus score is good for you. The
numbers range from 0.0 to 9.9 where 1.0 means a pawn and 0.5 means a half
a pawn value because of superior position.
The values are: pawn = 1; knight =3; bishop = 3; rook = 5; queen = 9.
Position superiority goes from 0.1 to 0.9.
Example - 1.75; Ivan thinks you are up in the position by 1 3/4 of a pawn.
Pressing the button one more time will cause Ivan to display the depth of
search that was just used to arrive at this move. The left number is the node
number and the right number is the ply number. Nodes are legal chess
positions the IVAN is examining each move.
Example 3 5 = The IVAN is examining the third position of the fifth ply.
