I will not comment on Chris captain's log stardate 1997.

The shown phenomena is different. You are wrong.
Your experience has nothing to do with the phenomena seen with mchess.
The deep lines (I would call 27 moves or more deep)
have no opening-theory in a human-game-library.
I tested this ! The games were not played by any human-opening-theory
nor any human-games from database.
And the answers played out fit to hiarcs6 answers.
Other programs would have played different and would have thrown out
mchess much earlier out of book.
Why are these lines in the book ?
Who has played them WHERE when ?
I can tell you, because this was my point:
Somewhere on an autoplayer mchess-experimental played them out against
hiarcs6 commercial and then the winning-games were merged/added into the
opening-book.

THIS is the thing I am talking about.

I have not get any comment from you on the specific opening-line I
posted.
No comment was made about the opening line Mchess played with black
against CSTal in Paris. No comment from Marty about the posted line.

Instead of calling other people whatever insults, you should concentrate
on the specific data mentioned.
When somebody gives data you COULD answer by showing other data or
comment on the data. You try to claim a campaign against Mchess.
This is wrong.
Mchess is a strong program but from my point of view the opening book is
somehow contraproductive !
Although these lines WORK (!!) they suggest Mchess would not win the
games without the preparation. THIS is my critics. I am sure Mchess
would do a good job without cooked book. Therefore I cannot understand
it.

Jeroen is a human beeing. Sometimes I am the same opinion he has, and
sometimes I am different opinion (I remember when he worked for Mephisto
and we met us at the Nuernberger Spielwarenmesse I was often against his
opinion ! :-).
Your construction of a campaign is not amusing.
Sometimes I agree with you. Sometimes with ed.
Sometimes I disagree. There is no money and no campaign behind this
phenomena.
It has something to do with the fact that human beeings have different
opinions.
The fact that human beeings have different opinions is not reason to
insult somebody ! I can have a different opinion than my best friend
without calling them nasty things. I can live with this. I can even have
different point of views than my girl-friend has. Maybe in your family
it is different.
But in my family we try to have our own opinions. And not anybody is
taking anything personal.
