You tested the contents of Sandro Necchi's brain ? You looked at his
analysis notes for the Sicilian Najdorf Poisoned Pawn ? You were with
him when he tested variations and sub-variations on several programs ?

And ?

Big deal. And this is your opinion only, not fact.

So what, do you want uniform behaviour from everything ?

Because they got stored as data.

Doesn't matter, its just stored data. Leanr your way around it if you
don't like it.

So what if autoplayer games are included in the book ? If the program
found the moves anyway (as it must have done) whats wrong with including
the moves as straight lookups, it saves time, no ?

Maybe they save the losing games as well, so as to divert away from the
stored moves.

Why is this a problem for you ?

So what. Are we supposed to be answering machines for everything ?

Thank you. I do but you don't notice.

Precisely. I posted a detailed alternative explanation is the post to
which you just replied. Ed replied to it. Jeroen replied to it. You all
have in common that you snipped the explanation and did not refer to it.

Ok, think your own fixed stuff. You believe it so much that an
alternative view is seen as suitable only to be censored.


> You try to claim a campaign against Mchess.
>This is wrong.

I was just asking the questions. The questions never got answered. There
was a pattern in the two rounds of attack: both at Mchess release time.
Both times Rebel team members were heavily involved. This time Jeroen
saw fit to keep on repeating stuff about Necchi.

Is looking for patterns not allowed anymore ?

Instead of answers, the messenger just got attacked instead.

Instead of looking at the alternative explanation, the snipping tool got
used.

Instead of participatory debate, the censors got appealed to.

I'll try again.

There's some data posted here recently. Mchess SSDF game results,
against Genius, I believe.

Roughly speaking, since I do this from memory:

mchess5 beats genius3 15-5 or so.

genius4 and 5 beat mchess5 15-5 or so


The generally accepted argument goes like this: we all know Mchess isn't
15-5 better than Genius, so the 15-5 result is cooked, due to the books.
When Genius team has a chance to fix the lines, they turn the result
round 5-15. Therefore Mchess is cooking books, Mchess is weaker than the
SSDF results indicate. QED. And, btw, Mchess is 'cooking', Genius is
'fixing'

Alternative argument goes like this: Once apon a time some programmer
did a lot of work on his book - this gave him an advantage. The other
computing programming teams started working on their books too, as a
counter. This process developed and continued year after year with lines
being cooked, fixed and cooked again.

The data 15-5 turned to 5-15 indicates *both* sides engaging in the
cooking-war or fixing-war or arms-race or whatever yoiu want to call it.
Mchess first, then Genius, only nobody actually knows who began it, and
nobody can ever stop it once it started. Note that this alternative
explantion doesn't try and apportion blame onto any one programming
team.


Now my gripe is this: you can call this process whatever you like, call
it evil book-cooking. Call it morally correct plugging holes, call it
what you like; but DON'T claim one side is 'plugging holes' and the
other side is 'cooking books'. They are both part and parcel of the same
process. And if you ascribe moral correctness to one side, and moral
incorrectness to the other you're merely taking sides in a war; and
that's the point at which questions get asked as to why.

Or, extracting the 'fact' that Mchess cooks its books based on the 15-5
data, and ommitting the 'fact' that it gets countered, and presumably
counter-counter-countered in a never ending spiral is just a plain
cheating argument.

There's a pattern that goes back to last year. If they don't like the
idea that this pattern could just possibly be construed as a campaign,
then they should avoid making the patterns, or else have a good
explanation handy. I haven't seen it yetr.

Really. You think going for a censorship attempt, dismissing arguments
with the words blah-blah-blah, and accusations of 'disgusting' came from
me ?

I think you see insults where there are arguments that you disagree
with.
