I thought it was clear what I was replying to, originally.  Here is a

My comment was then:

You speak of it being very difficult to know if someone was renaming a
commercial book if Chessbase books + GUI were allowed for non-chessbase native
engines in the tournament.  You state:

"This can't be controlled in a reasonable way"

My point was simple.  Just because a the Chessbase GUI or native book isn't
used, how do you know that cures the problem of using lines from a commercial
book?  So not allowing some participants to use the Chessbase GUI, but allowing
others to use ChessPartner and Chess Assistant really doesn't make sense to me.
Make a rule and make it uniform:  You can't use any GUI that isn't freeware if
your engine wasn't released with it.

As far as your assumption for accusations -- I was never suggesting anything of
the sort.  I know both of those games well -- the loss to Bringer in CCT3 was
quite influential at the end.

We had multiple problems in CCT4 -- most due to the early alpha we were using,
but we also fixed many problems as a result of that tournament.  I don't chalk
it up as an overall loss just because of its gross finishing rank.

It seems, however, that it was quite impacting upon you.  Take any version of
Hiarcs you want, remove the book and run a small tournament vs. Bringer to cure
that problem.
