I partially agree
- the fritz7 program is the only program legally using
the Kure book and this book is very WIDE, in contradiction
to other books.
- it has its own interface which is very tough to get
auto232 working against
- its winboard/uci implementation is not allowing
the opponent to ponder or to use hashtables usually
- fritz is using a hack of the auto232 protocol which
gives secret codes to other fritz interfaces, which
i cannot decode. It is not a released protocol. So
i do not suggest they ship other interfaces which run
older chessbase engines to make worse book moves and use
different learning files, we just do not know what it
is telling the other interface.
For sure is that if fritz is master it ships secret info
at auto232 to the other interface. There must be a good
reason to keep this protocol private though and it has
to influence the game scores.
- SSDF is playing real weak engines at outdated hardware, which
is simply not the reality in computerchess. In fact this
simply determines usually the rating at which programs
get rated in their list. In tournaments i never play old
gnuchess versions at 3 times slower hardware.
