Hi Chris,

I have no problems with Mchess.  I'm considering both sides of this
issue of cooked books and trying to do this in a detached way.  I'm
interested in the phenomenon and not attaching blame on anyone.

As I've mentioned before,  although I'm not sure it's "ethical" I'm
not saying for sure it's not either and it's hard to fault those
who MIGHT be doing it.

If I had a "hot" program on the list and felt others were doing this,
I might very well feel forced to defend myself with cooks of my
own.  And this happens of course in master chess too.   The real
problem isn't the cooks, it's the inability of programs to defend
against them on their own.

But I am rethinking this issue all the time.  I am trying to remain
open minded and do not think this thing is so clear cut.  I'm not
defending it but I'm not condeming it either.

It could even turn out to be a good thing.  The rules are simple,
anything goes and now programmers will be forced to defend against
this practice which might very well turn out to be a good thing
for all of us.   Maybe we should consider this a fact of life and
deal with it?   It's not like there are NO defenses to this
practice.  It might turn out that doing this stuff makes your
program vulnerable too.   If we simply consider this another part
of a complex equation then there is no problem.   Perhaps it will
become well known this this program has a great book, mediocre play
and this other program has great play, bad book etc.   It should
be considered another stylistic aspect of a programs personality.

On the other hand I like the idea of having a special rating list
for programs with completely randomized and very shallow openings.
This would give us an idea of a programs overall playing ability
on its own, and give chess owners more data to think and argue
over!
