Opening books and the will to choose the “right” opening variation are part of chess game. In the same way as permanent brain is.

Not to allow these features is IMO not chess.

Exactly. And as testers that is how most of us test chess engines in all or most of your points.

And I have no issues in testing with ponder on. As my system was built and designed by me do this type of engine testing.

But we do not force the engines to play 50 +/- 1.00+ openings of busted chess variations. And claim this is chess engine testing.

And to be clear TCEC does not claim to be testers. They run a chess engine site for entertainment and profit.

If some take TCEC seriously as testers. That is a delusion of their own making.

And this is what got Ed so upset. Because I do not respect TCEC as testers. Ed asked for this topic, and Ed got it.

You have already tried pier pressure, gaslighting, and now name calling.

And the facts remain, as they are by TCEC's on words.

Only facts matter to me Ed. Not emotions.

I agree that chess is also about using opening book.

The only list that I know that test with opening book is the ssdf rating list.

I can see that lc0 could beat stockfish15

https://ssdf.bosjo.net/nr001.htm

I could not find the relevant game when I download the ssdf data here
http://bozze.hopto.org/ssdf/games/

I could see that stockfish15 lost one game against lc0 0.28.2 simply by making a stupid blunder at the last move of the time control(move 200) and I suspect lc0 0.29 could beat it in a similiar way.

I wonder if there is one game that stockfish15 lost in the ssdf not because of the 40 move bug.

It is proof that they have run out of logical responses and must resort to an ad-hominem approach.
When you ridicule rather than reason, it shows you do not know how to debate.

No! What is insulting is making up facts, and that is being generous. Because you have no facts or knowledge on the subject. And that is insulting to me.

So get over it.... All I did was posted the facts publish by TCEC!!!

And If you are going to play the gaslighting bullshit game. Be prepared to get called on the bullshit.

Because the only people you two are arguing with is TCEC.

lol!

Do you have superior chess ability to Jeroen (2199) and GM Sadler (2694)?
If not, what gives you superior ability to calculate which openings are interesting?
Since you denigrate yourself with your responses, I have no need to stoop to that level.

These are the book exit positions, which you were not able to comment on:

As you can see, there are about twenty with a score of more than a pawn, which seems very one sided.
But if we examine the results using LC0 (latest version 0.30.0), which is more accurate in closed opening positions using the recommended t1-768x15x24h-swa-4000000.pb.gz nodes, we get the following scores for the most lopsided positions:

So we are not 'playing at pawns odds'.

For the most part, these openings are popular.
I have 1,821,984 distinct unique combinations of position + player in my chess database.
As an example, Wesley So has played 21 of these openings in his games.

So I ask, out of curiosity, what exactly are your qualifications to know how to construct opening books better than Jeroen Noomen and Matthew Sadler?

Here is a link to the opening book termination points with full analysis and comments:

Thanks Dann, looks good.

It depends on your goal. For TCEC's purpose, they might be as good as anyone else. Nelson was also in charge of the book at some point, surely he also met the criteria. What I contend is the very essence of said goal.

Well, I am currently testing the 300 TCEC positions, 3000 games, so far everything looks the same as my standard balanced opening sets I have in use.

What is the meaning that it is the same as your standard balanced opening sets?

Does it mean that percentage of the side that has the advantage in the initial position based on evaluation is the same?

Note that without looking at the positions I know that there may be some TCEC positions that black is better in the initial position and this is the reason that I ask about percentage of the better side and not percentage of white.

In these positions black is better:

I would say that that this is not a problem because all engines play the openings and play them as both black and white. So despite the loss of white's normal small advantage, they are fair.
Also, except for one which is rarely played, they come up very often in practice as is shown from the game counts.

What is the meaning that it is the same as your standard balanced opening sets?

Does it mean that percentage of the side that has the advantage in the initial position based on evaluation is the same?

Note that without looking at the positions I know that there may be some TCEC positions that black is better in the initial position and this is the reason that I ask about percentage of the better side and not percentage of white.

I guess by "looks the same" he means that the order of ranking of the engines is unchanged for this collection of openings as his other opening sets.

It depends on your goal. For TCEC's purpose, they might be as good as anyone else. Nelson was also in charge of the book at some point, surely he also met the criteria. What I contend is the very essence of said goal.

I think there have been shifts in book goals, as evidenced by the win totals and percentages over time:
https://en.wikipedia.org/wiki/Top_Chess_Engine_Championship
Of course, some of the smaller or larger win totals could be due to random fluxuations as well since the number of games is small.

This site:
https://www.chessdom.com/jeroen-noomen-and-gm-matthew-sadler-announce-tcec-s21-superfinal-book-cooperation/
says the following:
"Jeroen Noomen also notes that just like in the previous three TCEC superfinals there will be a lot more risky opening lines compared to TCEC 16 and before. This is necessary to avoid an excessive number of uninteresting draws. Statistics of the previous two superfinals show that a Leela book exit of +0.30 or lower is an almost 100% certain draw. The opening book of the previous season is available for download in pgn."

3000 games - TC 40/10
White wins 42.1%
Black wins 10.5%
Draws 47.4%

On this level I usually get a ~65 draw rate.

Most of the time I use the openings from Frank Q.

If some take TCEC seriously as testers. That is a delusion of their own making.

And this is what got Ed so upset. Because I do not respect TCEC as testers. Ed asked for this topic, and Ed got it.

You could behave a little nicer.
Seriously.
By accident others are also thinking along similar lines, so you got your point across
But your level of aggression really makes it a little hard to read your posts for me.
For most of us, dealing with chess engines is a hobby. So, e.g. -if I get kind of annoying answers I usually stop discussion.

I'd say the goal of the book was always to give engines playable positions, and by "playable" I mean that they would produce games people would like to watch. Raise the draw rates and people won't like that so much, so new lines replace old lines in the book, to lower it again. The content of the book changes, not the goal.

That could well be. The book line selection has not always had the same levels of great success. I remember one year where almost all the games were either the English or the French opening. After a while, there were a cascade of groans from the peanut gallery every time a game went French or English.
There have also been poorly tested lines that fell into a simple win, simple loss or forced draw immediately. But even so, if is not so easy to test for hardware like the TCEC contest because very few private citizens have hardware like that. I liked it better when Thorsten was running the show, but I still like the contest today. I'm not keen on it when it goes FRC, but that's none of my business and I am sure many do like it.
I usually did like Nelson's book lines and I liked chatting with Nelson online. I don't chat online anymore because I started to get bombarded with advertisements related to the content of whatever I was saying online. I don't know if that is still a problem. I miss some of the kooky characters like 'char' who frequented the early contests. Lazy Frank would also generate interesting content related to the contest in the Rybka forum, but that forum is gone now.

I wasn't ever very active, not even during Thoresen's tenure, but at least then I followed some games. Nowadays, I don't even include the games in my DB. Can a single line be enforced? Wouldn't your opponent deviate earlier on, to get a better exit point? I always looked at games from an opening theory/Freestyle point of view, which is why I throw out most of the games I collect and I'm now looking at the ultimate challenge, which is throwing out individual moves.

Still waiting on Ed's tool to provide an efficient way to do that Cool

Glad you mentioned this.
It is one thing for programmers to improve on their internal testing by playing games with lopsided opening positions to get meaningful results on potential improvements.
But it has killed interest in TCEC IMHO. This could be one of the hottest chess tournaments around (preferably with a good commentator), even if chess programs played like 50 draws in a row.
You could market this as „chess close to perfection“. Top grandmasters would certainly have a look at every single game for a few moments.And if they’ll do, fans will do that, too.
But who besides absolute computerchess nerds cares about the games themselves in the current setup? It is enough to just look at the final ranking.

Concerning these three hundred openings:
There are 20,341 games with those openings in the Online Masters correspondence chess database.
There are 62,249 games with those openings in the The Week In Chess database
There are 214,627 games with those openings in my Contest Games view (a collection of various contests joined together in a view)

These openings are commonly played.

No, they aren't. ( Your numbers are very low, Dann - and they are not between top players).

Humans are very pragmatic creatures. Right now the Scandinavian is busted e.g.. I chose this example as it might recover and is not so clear. Unless the problems with it are solved somehow I couldn't care less about watching more games to show it ( or watch Stockfish being busted and STILL draw).

For the time being, Scandinavian games are just irrelevant for me.

Humans are very pragmatic creatures. Right now the Scandinavian is busted e.g.. I chose this example as it might recover and is not so clear. Unless the problems with it are solved somehow I couldn't care less about watching more games to show it ( or watch Stockfish being busted and STILL draw).

For the time being, Scandinavian games are just irrelevant for me.

They are filtered for gm level. but some of the games might be old.
