FIXED TIME LEVELS
The computer will always respond in exactly the specified amount of time,
unless it has only one legal move, in which case it will play instantly, or unless
it sees that it can force checkmate, or can not avoid being checkmated, in
which case it will make its move as soon as it finds the mating sequence.
Remember the longer you allow the computer to think, the stronger it will
p l a y .
GAME MEMORY
You may interrupt a game and save your position at any time by pressing the
ON/OFF button. Play is then suspended, and the computer will remember
the current position. Ivan will remember your position as long as you do not
interrupt the power supply! When you switch on again, the computer is ready
to resume your game.

Ivan has 100 different levels. Levels 1-94 are used when you are playing a
game against the computer. Levels 95-100 are used to make your computer
perform a position solving search.
THE PLAYING LEVELS
At the start of the game the computer uses its openings “book” which contains
thousands of moves, and when it is still in its openings book the program will
move instantly. Once the program is out of its openings book the thinking
times for the various playing levels are:
Level times and Responses
LEVEL 1 User Adaptable: The computer calculates the average time you have
taken over your past 6 moves and will respond in the same average time. If
you slow down, the computer will also slow down. If you start to play more
quickly, the computer will also play more quickly
FIXED PLY SEARCH
Levels 6 is the fastest and weakest level and your computer will respond almost
instantly on every move. The playing strength improves progressively from
level 6 (the weakest of this group of levels) to level 2 (the strongest of this
group). When you put in new batteries or when you switch on the computer
while using a power adapter, it will be set to level 6. This level is designed for a
beginning player, using only a 1 ply search. A ply is a half move. When the
player moves and the computer responds with a move, this is one complete
move. There are 2 plies for one move. If you are a beginner and you are not
winning in level 6, we have some additional things you can do to help with
your chess training process. One option would be to use the SETUP f e a t u r e
and remove the computer’s Queen and then begin the game. With a Queen
advantage a beginner should have a better chance against the computer.
When you win in this position, return the queen and then try to win by
