Subject: The Strength Rating of Machines resulting from Games vs Humans Part 2

What is the characteristical factor of machines in chess. Following the brute
force combined with selective issues it is clear that a machine plays perfect
chess unto a specifical depth. No matter if it's 3 moves and a half like in MMIV
or 9 moves in DB2, this enormous depth is beyond the capacity of normal
amateurs. Weaker amateurs can't play to a depth of 3 (6 plies) moves without
making mistakes. Losing material to be exact. 8 or 9 moves is even for GM a
tremendous task, also because he knows that he would lose for sure if he would
lose something.

A super GM is the only one capable of such a "faultless" play. Always depending
of the depth. Also his calculations are without mistakes. Depending of the
required speed.

Now it is clear that a machine can't play chess like human chessplayers. It has
weaknesses behind the brute force oasis; often such details are piece of cake in
comparison to human chess, and above all they have a kind of deterministic
characteristic, they appear like a "zwang" so to speak; humans make blunder but
this is by chance not by determination. To examine all that would cost enourmous
amounts of time for a master. Why should he do such a job? For normal
tournaments it wouldn't pay off. However if that would be done once and for all
we would have the technology of perfect winning against machines. Until now it's
all about trial and error.

Viewed from serious science a show event of six games is a gamble for sure. In
special because the machine is always a new construction which couldn't be
examined before. Therefore chessplayers with a natural instinct for money are
seeking a draw for the whole event. This doesn't hurt his own psyche too much
and allows a superb PR for the companies. But it's still a hoax.
