Hi Karsten,
thanks for answering.
[first two posts snipped]
I had wondered why Fritz5 was out of book in a position where my
powerbook version still was in.
You wrote an explanation:

But then there remains the question, what kind of "powerbooks" these
were.
It seems not only in this position Fritz was out of book unneccessary
earlier than with the original powerbooks (sometimes book lines can be
too long for creative computer play, but not this time from my view). In
an even much more extreme form this happened in the following game:
[Event "Mensch-Computer-Turnier"]
[Site "Aufsess"][Date "1998.03.20"][Round "4"]
[White "M-Chess Pro 7 PII-333"][Black "Fritz 5 PII-233"][
Result "1/2-1/2"]
[ECO "D50"][PlyCount "73"][EventDate "1998.03.??"]
1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 dxc4 {Selbst errechnet!}
This, frankly, looks more like a "non-power" book than like a power-book
:-))),
being out of book in move 4 in the main variation of the Queen's Gambit
Declined???
Was there any relation of the book used to the well known power-books or
was it "something completely else"?
And what did the Chessbase team want to achieve by using this kind of
book?

Don't worry, I still have the difference between computer chess issues
and "god's words" in mind ;-)
I just don't see any reason to give room to rumors Ossi Weiner has
introduced here without any evidence - probably for quite obvious
reasons of trying to benefit from such rumors with the programs he
sells, which are not No. 1 in the Swedish list at the moment :-)

Here again I don't mind at all any small machine difference between an
MMX200/233 or K6-200/233 or similar. And I can well imagine Mchess 7
winning such a tournament on a MMX-233 instead of a MMX-333.
It just might have been even more interesting to see *all* machines play
on similar hardware and not *one* of them running 100 Mhz faster than
the numbers two an three. This way you never know if it happened for the
considerably better hardware or for program strength.
The games are quite interesting nevertheless...
