Your favorite engines?

[Frank Quisinsky]

Madeleine,

engines strong in closed positions with many pieces on board are strong in king safty too.
Engines strong in king safty are to 95% strong in king attacks.

If an engine can produced a strong idea for a king attack, same engine can produced a strong idea against a king attack.
That's pure logic.

With other words ...
Programs, strong in king attacks have a very strong king safty.
Spark is the best example with 2775 Elo and many pieces on board.

To find the strongest engines for opening analyzes is to used most complicated A00-E99 positions. We have all in our FEOBOS-1 project (available on my site).

Dutch and King-Indian opening systems are good examples ... very complicated lines for humans!
Gambit-Systems are bad examples because for engines with more as 3000 Elo is the game lost with -1 after opening book moves ... in most of cases.

For FEOBOS project I need not only 8 programs strong in king attacks alone!!

Mixture = 8x strong in king attacks and 2x strong in positional chess.
Here the pawn structures are most important and of course the right exchange from pieces in closed positions.
Ethereal can play very fine positional moves. At the moment I am working on stats to "Pawn structures" in closed positions and Ethereal stats are fantastic.

Important but not my main topic ...
I have to find out 8 engines for king attacks ...
That's the main topic!

2 engines for fine positional moves are quite clearly (Komodo and Ethereal).

So after all ... again 10 engines will analyzes the A00-E99 lines.

To explain FEOBOS in my bad English ... not this evening.

Frank, I have a feeling you'd like Komodo Human. Very strong attacking personality and likes to play with many pieces on the board and win in the middlegame phase, if it can.

Of course, it's not the default setting, but we must think outside the box once in a while.

[Frank Quisinsky]

Stockfish is much more aggressive as Komodo in mid-games but Komodo is prospective in "pawn strutures". I think this is the biggest different between this two engines if I am not looking to the passage into endgames (statistics are to complicated). 34 of 500 ECO codes produced more or less a fast endgame. Komodo is for that reason very important for opening analyzes.

Komodo and Ethereal are very complex.

Better ...
Stats to positional strengths are very complex and need many time.
Stats to aggressiveness are much more esay!

But if I try to do that (stats to pawn structures for an example) the results from Komodo and Ethereal are allways fantastic.

More as two engines with strengths Komodo or Ethereal have I don't need for FEOBOS.

Biggest wish by myself:
Analyze mode for Booot should be works fine.
Here I had biggest problems in time FEOBOS v1 are still running.
Not checked that with the last two Booot versions.

8 new engines in FCP Tourney-2022 for myself.
No idea where are the strengths from Berserk or Koivisto, others.
So the stats to the still running tourney will be very interesting for me.

[Frank Quisinsky]

Another point is: Eval.

The last FEOBOS project ...
Fire was very interesting. The eval from Fire is more realistic as from all other 9 engines (if we put a template over 40.000 positions).
Engines like Stockfish gave eval +0.8 ... three moves later +0.3, and for the same moves Fire have allways +0.2 (for an example, older FEOBOS project).

Eval from Fizbo, iCE, SmarThink jumps in big steps and that is bad for "Engine-Teamworking".
Will not lost good positions if engines give no realistic evals.
Houdini is another good example: Eval is +0.3 - +0.4 higher as average of eval from others in open positions.

Different things are important:
Realistic eval
Analyze mode
2x Engines, strategical strenghts.
8x Engines, tactical strengths.

All 10 should have a strong king safty.
And I am sure this group of engines, on 32 threads and 1-minute per position analyze time, will give me perfect results.
FEOBOS v2 will be mutch better as FEOBOS v1.

The group of 10 engines will be build after FCP Tourney-2022.
And with FEOBOS v2 the next FCP Tourney-2023 will be again more interesting.
Stats to playing styles are better and better.



I am so crazy!

...
Seer 2.3 -- Unfortunately, Seer crashes when I try to analyze a fen and it has no options, but the evaluation is different, and very good in simple positions. I hope Connor will fix this bug. Winter -- Nice, positional engine -- unfortunately, Jonathan seems to almost have stopped developing his engine.
...

Seer only accepts valid fens. Perhaps you're feeding it malformed fens?

[matejst]

Connor,

My bad. It seems it is a problem with the Shredder GUI: Seer crashes when I set up a position in this GUI, or when I paste a position in this GUI. But when I copy that same position and paste it into the Fritz GUI, Seer works flawlessly. So go figure.

[matejst]

Frank,

In general, the evaluation of nn engines seems inflated.

[Frank Quisinsky]

Hi Boban,

same others told me.
Can be a big problem for the old rules we created for the first FEOBOS project.

New rules must here ...
OK, should be solve for FEOBOS v2 before we start the project.

BTW:
What Connor wrote here to Shredder GUI.
Seer is a very interesting development for me. I have a lot of fun if I am looking in Seer games. The style I like! Seer is one of the 10 engines I will include in the project and the analyze mode for Shredder GUI should work for FEOBOS.

01. Komodo
02. Ethereal
--
03. Wasp
04. Slow
05. Booot (if working)
06. Seer (if working)
07. Stockfish
08. Revange
--
09. no idea
10. no idea

What I have in my brain, but changes are possible.
I have to wait of the own statistics after the still running FCP Tourney-2022.
Possible that I am using for FEOBOS v2. 12 engines!
I am not alone, opinion by Klaus Wlotzka is important!!

Fire should run, most interesting eval in the last FEOBOS v1 project.
Again not sure which engines should run in teamwork for FEOBOS v2.

Frank

For your nr 9 & 10 ,maybe Berserk & RubiChess

[Rubinus]

I cannot use Smarthink afther the 1.90 version -- did not try too hard, though. I probably lack some dll on my computer. I also liked a lot of old engines ...

http://www.sdchess.ru/download_engines.htm
The very 2nd line is Smarthink. There is a link to some dll among those links, but the site is quite old, I don't know if all the links are functional. I don't have any dll directly in the directory, so if it needs it, I probably have it installed in Windows 10. I have, among other things, Microsoft Visual C++ for x64, from Microsoft, installed. It used to be free.
