Ok - lets say Kasparov wins against Bernd Kohlweyer
200 to 100 !

Now lets take 20 girls and let them kiss Kasparov and Bernd.
Let them both drink 20 beer.
Let them play again and watch if Kasparov wins still 200 to 100.

Now what shall this example tell us ?

I tell you what this strange example wants to say:

Take Fritz5 on a 486-33 with 1 MB hash and also Cstal on a machine with
the same hardware and hash.

Let us guess what will happen ! Fritz loses 200 to 100.

Now put them both on a k6/200 and give Fritz5 1 MB hash and also CSTal
k6/200 and 1 MB hash. Let us see what happens.
Maybe CSTal now wins only 170:130.
Now give fritz5 128 Megabyte Hash-tables and also CSTal 128 Megabyte
hash-tables.
And suddenly: Fritz5 wins 200 to 100 or even more.

What has happened. Although you have always upgraded BOTH machines in
the same way, very fair for both programs, same hardware, same amount of
ram, you get different results.

The same thing happens often with humans. Although the same guys meet
each other year by year, and although Kasparov is stronger than
Kohlweyer, maybe he is his fear opponent and maybe yesterday Kasparov
had a bad dream about Deep-Blue and is down and maybe, whatever, and
Bernd wins "again".

I think I can measure the system immanent problems and the CHANCES a
program has, the chances to win. With measuring this chances I can
etrapolate out of a few samples although it should not be possible.
Maybe I don't really know the reasons. But I can feel them and this is
enough to extrapolate the conclusion.

When chess program X plays program Y, some mechanism work against each
other.
Similar mechanism, but biological ones, happen when humans have to play
each other. And although anything is FAIR and no cheating, strange
things can happen.
NO measuring system can handle THESE strange effects. But the human (and
any animal brain) can handle them- let us call it fuzzy-strategy.

Using this fuzzy resources anybody of us can extrapolate or find out if
he is used to do it.

Don't you have a thing that is non-chess-topic where you are used to do
it for 20 years, and you are an unknown "expert" in this area, and you
could make bets that you will be succesfully be able to claim in forward
what will happen ??

I am sure anybody of us has these FEATURES ! My grandma e.g. was very
very succesful in finding out WHEN I WAS NOT SAYING THE TRUTH (in my
youth as a child). And she was a succesful in finding out with other
persons. Nobody in our family knew HOW she has done it. But she was able
to SEE a lie.
It was always a very HOT birthday of my grandma, when many guest were
invited. Nobody tried to lie. They all had their shameful experiences
with my grandma!

Only good luck ??

Don't get me wrong. I am not sitting the whole day in my appartment and
doing meditation or believing in ghosts nor do I try to walk over water
or to fly in my appartment !
