Ethereal is a magical chess playing program as I wrote several weeks ago in another thread ....

Ethereal programmer could take over the top engines if he concentrates his efforts ....

Watch out for this chess engine as the future versions will be much stronger ....

Cheers,

Hi Ed,

looking what you do in the last years on your site.
Just a nice work, so many years.

But what I missed from yourself ...
More material and stats about pawns.

The secret for a high Elo are pawn structures!!

A grandmaster told me for many years that I should replay grandmaster 1:0 or 0:1 games with more as 60 moves. In my brain I should have only the pawn struture, not looking on the other pieces. Only on pawns and king. The grandmaster wrote, that he missed a GUI that he can replayed games where he can see only the pawns and king on the board. More easy for training. Knight's or Bishops are only interesting for ... on which positions are the pawns if Knights and Bishops switched.

If I do that with houndrets of games the next step are the rook endgames and open lines ... the words by a grandmaster!

Start of 2020 I do that.
I replayed a lot of games from best engines I produced with FCP Rating List. What Komodo do here is fantastic. If I am looking on pawns only it seems that during a game Komodo try to hold the pawns each time of the right fields with a very high priority. Komodo is not playing very aggressive with pawns with many pieces on board but try to hold it on best positions.

For engine developers maybe today most interesting are the pawns structues for make engines stronger.

You are the right person and you can developed own ideas (can be easy see in the things you do).
You are programmer and helper too and I sure you know that how grandmaster's try to learn.

But we have no GUI we can replay games and can see on the board only king and pawns.
So many ideas here but my work with Martin Blume ended and to create stats about it are very complicated and need many time. So I have the ideas, but so long I have a professional job ... not the time for it.

Best
Frank

Hi, Dr. D.



In the last four years I am using to many times with the older chess computers and have much fun with the older chess computers.
Also using time for FEOBOS or in testing Wasp but I lost a bit the view for other engine developments.

It seems that you looking in detail!
You do that all the time if I remember

Magical is the right word by yourself I think.

Now I will see more of such things in the next 48 rounds of my tournament.
But sure here, Ethereal will produced much more of such material.

11 of 80 ... just amazing!

Best
Frank

[Frank Quisinsky]

Hi Dr. D.,

if an engine have an average strenght in competition to Komodo or Stockfish for endgames but comes with a clearly more aggressive style in middlegames ... all is possible. So the Ethereal programmer is on the right way. But I am looking never for endgame strength. Thats is really boring for humans because all of TOP-200 engines have the Grandmaster level here, not in middlegames and openings.

If a programmer goes here an other own way he will find a lot of fans. But a lot of knowledge about statistics and fantasy must a programmer have. That can't be knowledge about programming only. So Ethereal have an own and interesting face.

Looking in the times Houdini are on first position a long time.
Robert have own ideas to the right points humans like, can be see in the style Houdini produced.
Later Stockfish have the same playing level as Houdini. It was nice to see that Houdini plays more aggressive as Stockfish with the same level. So Robert make differents things really better as the others.

Again, the secret are the pawn structures ... to 95% sure here!
Sure, the Ethereal programmer find out a lot about it.

Best
Frank

PS: Many of us like the LCO playing style. I replay a lot of LCO games. In endgames such engines are not more interesting as Komodo or Stockfish. The secret here is the middlegame. Humans like the middlegame and for such reason the style LCO produced is for humans interesting. In most of cases the great games by LCO are produced with aggressive pawns. Now we are in the year 2020. With lesser pieces on board engines are not to beat. The advantage from Stockfish from versions 8 to 9 to 10 to 11 are in the transposition into endgame, not in earlier middlegames. The other way is more interesting ... how I can make an engine stronger in earlier middlegames. Thats for humans much more interesting as the perfect strength in transposition into the endgame. If we find out a new engine comes with a nice middlegames we all will like that.

To the topic pawn structures it seems we can go two ways:

Way 1: We make the pawns more aggressive but we lost endgame strengths
Way 2: We try to hold the pawns on the right fields without to produced speculative attacking moves with pawns and the endgame strengths goes higher. The way Komodo goes after all I can see.

A combination from Way 1 and 2 ... not easy to find out in programming. Maybe the Ethereal programmer is here on the right way.

The same in the years Spark, Aristarch, Phalanx are available later Glaurung. We like such things a lot. Engines that can produced fast won games in middlegames are allways interesting. Thinking on TheKing in chess computer times.

[Ovyron]

Sorry, but these long book lines are obfuscating the engines' styles. The question is not if the engine would play the amazing move that you see (because many others would have played it as well if given the chance) but if it leads the game to the positions where that happens, instead of the book making that decision for them.

[carldaman]

Thanks for posting the games, Frank - and great to see you around and active again.

This should put to rest any talk of Ethereal being a boring, style-less engine.

Try to take a look at Winter, too, including previous versions. The programmer is a master chess player.

I've known about Schooner's pleasant style since it was 'just' a 2500-rated engine, and having a lot more strength hasn't really detracted from its style.

[carldaman]

Sorry, but these long book lines are obfuscating the engines' styles. The question is not if the engine would play the amazing move that you see (because many others would have played it as well if given the chance) but if it leads the game to the positions where that happens, instead of the book making that decision for them.

Good point, Ovy/Uly. I would rarely use long book lines, except maybe when I want to looking into an engine's ability to handle a certain tricky variation. Getting a book win/loss, no matter how pretty, takes a lot away from the result.

[MMarco]

Examples:

Sorry, but these long book lines are obfuscating the engines' styles. The question is not if the engine would play the amazing move that you see (because many others would have played it as well if given the chance) but if it leads the game to the positions where that happens, instead of the book making that decision for them.

In my rated tournaments I use the opening book up to the 12th halfmove and then I let the engine on it's own ....

You are right,sending the engine nearly to the endgame stage will affect the rating of the games ....

Hi there,

FEOBOS Book Lines ... all FEOBOS lines = 3 moves after ECO code ended.
If we used opening book up to 12 moves, different of the 500 codes are not included.
So we go an other way because all of the 500 lines engines should play.

All FEOBOS opening lines end positions (for Contempt 3 = over 33.000) checked by 12 engines with 1 minute analyses on 6 cores. The complete FEOBOS analyses by 12 engines, the Excel file about it (over 16 millions of formulas) can be found on my site.

Book is completly bugfree.
Documention, PGN, EPD and all other files around this project are available on my site.
Project time = 4 years:
Downloads at the moment: 17.322

For more information please download the files or have a look on FEOBOS detail page.

Best
Frank
