I entered the tour and games to Deepseek and this is what it found, however what surprised me is that it does not know that BrainLearn and SpecTral handle Q-Learning, outstanding!

Key Findings
Extreme competitiveness:

Only 37 Elo points separate 1st (Corchess 190125: 3819) and 46th (Cool Iris 13.97: 3782).

Minimal differences (1-2 points) between leaders reflect technical parity.

Predominant tables:

>85% draws (up to 91% in SF-POLY 210924a), indicating conservative play and risk avoidance.

Stockfish domain:

7 of the top 20 are Stockfish variants (ex: SF-PRO2, SF-PB).

Minor updates (e.g. dev 16 and dev 17 in Stockfish) impact ±1 Elo point.

Reliability by game volume:

Engines with >3000 games have reduced error margins (±3-4 vs. ±5 in <2000 games).

Featured Patterns
Draws not correlated with Elo: Leading engines do not always have the highest rates (ex: Corchess 190125: 89% vs. SF-POLY 210924a: 91%).

Competent alternative engines: Brainlearn 30 (9th) and SpecTral v2 (10th) stand out with innovative approaches.

Conclusions
Microscopic innovation: Differences of 1-2 points require hyper-precise adjustments in algorithms.

Consistency > Risk: Maximizing positional advantages (pawn structure, center control) is key in the face of high draw rates.

Niche Specialization: Engines like Killfish 021224 (4th) can lead in specific areas (ending, tactics).

Best regards, Sedat!

Thanks again Mr. Anton,

And as usual, always interesting to read your comments!

Have a great day )

UPDATE 2

Some notes and questions more,
1.Why SF-PRO2 250125 is performed better than other SF-PRO series?
2.Balsa + Unique openings are played any influence about results?
3.Any news about newer Balsa or Unique suite will be ever released?
4.Running 1000 games (per player) via UHO openings are enough..?

Well, let Me start to answer about 1st question:
Why SF-PRO2 250125 is performed better than other SF-PRO series?
I'm not a programmer, but as far as I noticed (in LIVE games too) :
SF-PRO2 250125 spent much more time till mid-game than endgame!
E.g more than 90%-95% of its time is used mainly up to 30-40 moves..
And later, SF-PRO2 250125 is started to play too much quickly, reason
To avoid to not lose on time..yes, in most of its games is managed to
Not lose on time, but just in some (9 games) are ended as time loses!
So I think that as golden key is played here about why SF-PRO2 250125
Performed better..in same time means (at least via this engine ver.):
Spending more time till mid-game is more important than endgame!
But where, the latest tested SF-PRO2 280125 version is used to play
Via more balanced time (per games) due move overhead 200 helped..

About the free SF-PRO 311224 ver, which is ranked as 44 rank:
No comments, exception rather I'd say the available SF-PRO is
Quite new engine too..just it's released about one month ago..
Btw, it seems SF-PRO 311224 is stable, no time loses games!
But why performed not better? here SF PRO's author may know...

About 2nd question,
2.Balsa + Unique openings are played any influence about results?
Of course...here Quality, Strength, Time... are said the last words!
As we noticed, even 1000 games (per player): CorChess was as BEST!
And after 2000 games, again CorChess, after 3000 games: CorChess...
Btw, if you going to ask why via UHO openings, CorChess was not..?
Then I suggest to read 4th section/question...please see below )

On other hand,
I'm not going to prove about my openings knowledge is good or bad..
But in the past, even actually nowadays, my favorite openings are
As one of best... sure I refer for my played tours categories! Btw,
Do you want to prove again via Online, in 2025 too? SORRY, after
25+ years, I'll not do that again and again...but probably many online
Players (in the past) know that my opening books were not so so weak!

About 3rd question,
3.Any news about newer Balsa or Unique suite will be ever released?
Yes..will be a new release.. for example, I am still working over
Newer Unique suite version which is highly based on Balsa openings,
But as main difference will be optimized for 3800+ players as well!
Where it's expecting to see a lot of spectacular games and in same
Time I am working regarding which produce less draw perc. values!
E.g the target is to be about 80%-90% draw ratio in Bullet + in Blitz!
Sure in slower TC, situation is unpredictable..since serious test required
But I guess, the draw numbers will be higher, reason: more time means
More assistance.. more and BIG assşistance (such as via NNUE) means
No much ways to appear blunder moves..so almost all games are ending
Draw! So here we can not blame Top engines or openings..hope helps!

No doubt too that just in case of..the fools, the trols will blame
Again that my openings are Drawish! they will say also that I am a
Cheater, a Liar.. etc. and again and again these 'perfect fools' will forget
To mention that my opening are one of best! As one of most funny thing:
They always forget to say that theirs games (via weak openings) are bad
Quality etc. if still not so clear ?
At least in SCCT Book Tours: all cleared, which is good, which is bad!!
But I'm afraid to say also these perfect fools will never learn about it!
Btw, not always, but sometimes I respect them too! do you know why ?)
Because without the clever fool guys, our hobby would not be boring ?))

About 4th question,
4.Running 1000 games (per player) via UHO openings are enough..?
Definitely no...here it seems at least 5.000 games are required for
Better stats..as reason, here almost all weak, critical openings..maybe
Later I can do more tests via UHO series, but I don't want to promise..
Just in case..who knows ? maybe after 5.000 games: CorChess will take
The lead..but via Balsa or Unique suite series: 1000 games was enough!
Right ? Or maybe I am missing something..?

And as last words, for anyone missed:
Learn also that CorChess is managed many times to be Champion:
https://sites.google.com/site/computers ... eng-champs

After all,
what does it mean? CorChess is so good in fast TC as well, right ?

Ok..that's all for now.) hope helps..and thanks for your reading...


Best,
Sedat

UPDATE 3

One thing more, but as another important notes too:
Since NNUE 2020, what is born, what we read by many guys?
(Sure some of them are fake, belonging to trollers etc.) e.g
Such as everything, related that ends as draw is bad, not good..
Sorry to say, but what kind of sick mentality can be of that ?)

And if still not so clear, here as other examples if NNUE Top engines:
Leko, So, Vidit plus many other great humans players openings, plus
Including DON, HCAN, OPTIMUS, Perfect etc mostly ending as draw !
And now what ? if more draws..all of our used openings are as bad ??
That's it.. here is the key..since what we see by some people in our hobby,
Such as they try to blame our favorite, strong openings...sad but true!

Meanwhile, if all we will follow theirs funny, sick mentality.. then
1000- 3000 Elo engines are better than 3800+ LOL )) because they are
Less DRAWİSH engines! sure I refer via Balsa again... try it.. if you have
No clue..and then report please..but you will never see so high draws..!

And it seems that these brains are far way e.g what's good, what's bad..
Btw, did these perfect fools play at any serious tours on Lichess or on
Playchess eng room? Or at any other platforms..let's say in SCCT too?
If not...I invite them...just in case..GOOD lessons will be..for sure!
And I promise all for free...Don't miss it...sure if you still not participated..
And stop running your silly games on your own PCs, because I think also that
It's totally a waste of time, if each time preferring only the bad, weak lines!
Because to be on Top (one of best): not so logical weapons to be a Winner..
In other words, try some new ideas, but better...and then who knows?
Maybe next time you will be as Winner..but before, I suggest harder and
Smarter work !! and just because is very hard..it does not mean to give up,
Try again and again !! Others are managed to do that.. and why not you ?)
Just in case.. wishing you good luck )

Hope helps too...

Hello Chess Friends )

As usual, I am pleased to announce,
NEW (1min + 0.5sec) CS is started !

What is New & Tournament's Target:
1st. Up to 30 MB (compressed size)
2nd. Chess Engines with 3650+ Elo
3rd. New Unique Opening Suite 2025
4th. Each will contain 1000+ games
5th. All via default Evalfiles, exc.
CfishGN via nn-a27a526755f0.nnue

In other words,
Just one same kind of Evalfile allowed..and here 1st gauntlet test,
And after...sure if all right, then Round-Robin tour will be started..

What I can add more, current cond. are not perfect, but ideal..!
Moreover, it's much fair, besides no Double Standards.. You know,
Some testers avoid many engines..such as they are clones, hehe ))
I wonder, in their tests.. all original? if so is there any proof over?
Frankly I hardly doubt...but this is life, we have to live with that!
By the way,
If all people will be same..then our World would not be boring?)

Anyhow, enjoy with SCCT results...and wishing good luck to all )

On other hand, separate tours organized..e.g up to 30 MB (compressed),
Which includes Top engines min. 3650+ Elo and the other tour includes
Stronger players, sure via bigger NN Evalfiles with over than 3800+ Elo, in
Same time that means we've 2 Champs, the Winner of 3650+ (Small size):
Obsidian 15 where the Winner of 3800+ is SF2-PRO 290125 and how nice
That both engines are as 1st time Winners in SCCT tours! Btw, CorChess is
Proved again to all of us that belongs to the strongest ones but unfortunately
Lost (in tie-break of 1276 games, where SF-PRO2 290125 is managed to win)
And please stay tuned, soon as possible 3800+ tour results will be shared too..
