Hi Vincent,


Yes, it is true, but the opening selection of Fritz did help him.

Yes, but on a match one needs to make the following considerations:

1. where is the opponent stronger?
2. does it have some weak points?
3. do the chess program have stronger points then the opponent? If yes, which
ones?
4. which openings or positions does the opponent play usually?

So, Kasparov is stronger than any chess program, but not in everything. In order
to reduce the gap/and or have better chances it is necessary to be able to spot
the opponent weaknesses and reach positions better for the program.

This will change the strength ratio. If the ratio is too high it may be
impossible to have any chances.

To find the way to decrease as much as possible the opponent strenght and put
the computer to play at the highest possible level is not easy.
I have been working on this for many years hoping to get the chance to be in a
team facing Kasparov.
I hope I will have the chance soon.

One day the computers will be stronger than the strongest human chess player.
This is sure.

The question is: how far away is that day?
