the side to move by pressing the q /n
key.
Finally, press CLEAR to play or to have
IVAN analyze the position.
Remarks about IVAN
IVAN says things based on a number of
factors. Some factors are time, a winning
or losing score, a training position, or
level setting to name a few. Try removing
IVAN's queen from the chess board by
using the procedure on page 9 for
Removing A Piece as an example.
If IVAN gives you a hard time when you
ask for a hint or try to change sides, press
the key again, and IVAN will comply.
If you can't wait to experience his com-
ments in across the board play, IVAN can
be coerced into letting you hear a number
of them. The method to enter his special
DEMO mode is to first press the LEVEL
key. Now press the TAKEBACK key, and
IVAN will display DEMO
phrase. Finally press the OPTIONS key
to hear IVAN at his talkative best. Press
CLEAR when you have tired of his end-
less chatter.
Don't forget you can always turn IVAN's
character mode off by using the
OPTIONS key. However if you do, be
prepared for one last word from IVAN.
General Rules of Chess
1. The two players must alternate in mak-
ing one move at a time. The player with
the white pieces moves first to start the
game.
2. With the exception of castling (see
below), a move is the transfer of a piece
DEMO, and say a
from one square to another square which
is vacant or occupied by an enemy piece.
3. No piece, except the Knight may cross
a square occupied by another piece.
4. A piece moved to a square occupied by
an enemy piece captures it as part of the
same move. The captured piece must be
immediately removed from the chess-
board by the player making the capture.
5. When one player moves into a position
whereby he can attack the King, the King
is in "Check". His opponent must either
a) move the King
b) block the path of the attacking piece
with another piece, or
c) capture the attacking piece.
6. The game is over when there is no
escape for the King from an attacking
piece. This is known as "Checkmate".
7. The game is over when the king of the
player whose turn it is to move is not in
check and the player cannot make any
legal moves.
"Stalemate" and is considered a drawn
game.

2. The Rook can move to any square
along the same row or column on which
it stands, but cannot pass over an enemy
piece. See also Castling (on right.)
