Yes.

If the author/manufacturer of the engine does not make the necessary effort to
provide a book, he gets what he deserves.

Yes.

There's a real world out there, you know.

If you don't make any effort, you get slaughtered in the real world.

The King is a very strong engine, maybe stronger than Chess Tiger.

I have the greatest respect for Johan and his work.

Are you happy now?

I'm just saying that no special favor should be given to any competitor.

When I asked the SSDF if it was possible to send an update to the Tiger 14
opening book, they required that the improved opening had to be made available
for free download to all customers immediately.

And it was a perfectly fair requirement.

So we made the improved book immediately available for free download to our
customers.

Johan has, I think, enough fingers to build a suitable opening book for the SSDF
test, to send it to the SSDF, and to make it available for free download.

I don't understand exactly why he would be exempted from this.

I don't understand why he would receive an unfair advantage as a reward for NOT
complying to the most basic rules.

It is not unpleasant. I'm not #1 in the list. I'm not even #2 or #3 anymore.

What do I have to lose? Can you tell me? Dropping from #5 to #6? Oooh I'm
scared... :)

My opinion is that The King (CM9000) deserves to be in the list.

The problem is that allowing exceptions to the simple rules of the SSDF is going
to turn the list into pure garbage.

I'm in favor of fair testing. I have always been.

However this requires a minimal amount of cooperation from the engine's author.

Actually I believe that the author does not want to be in the list. Or does not
care. So why should the SSDF reward him by giving his engine TWO UNFAIR
ADVANTAGES?

You are right. Johan said it prefers the improved settings to be used, and
that's perfectly fine.

It has always been allowed, and it is a good thing. No problem here.

People want to know the best they can get of a single PRODUCT. That's the
question the SSDF ultimately wants to answer: "what is the best chess PRODUCT?".

Historically, the SSDF does not try to answer the question: "What is the best
product out-of-the-box?".

So applying better settings is allowed. No problem.

And it does not try to answer the question: "What is the best cyborg one can
build by using parts of all the other products around?".

So the recipe for a good SSDF test is:
* get a product
* apply the settings recommended by the author of the engine
* apply the various free patches known to improve the product
* test

Adding a new step "mix the product with whatever good thing you can find in
another product" is like opening the pandora's box.

It was already unfair.

Sorry, but your comment is shortsighted.

Many people who have no commercial interest in the SSDF results share my opinion
on this issue.

And I think that you greatly overestimate what my interests in this can be. The
rating of CM9000 will have absolutely no impact on my business.
