Hello There,

As usual, I am very pleased to announce:
Here is just another New Unofficial Test!

What is New ?
Exactly same cond. as recent LXIII CS is used,
https://sites.google.com/site/computers ... nnue-cs-63
Exception this time UHO 2024 BIG +0.80 +0.99 openings is used!

Reason of running this new test is that,
-Simply to check again the influence of
UHO Openings, which are much less Drawish,
But In same time..they are much more critical,
And much weaker than Unique openings for sure!

Moreover, in the end... we'll have opportunity,
Chances again to check draw ratio, but with close
To +0.80 +0.99 Advantage/Disadvantage openings!

As other very important issue (at least for my side):
For example, if running about 1000+ games (per player)
Is enough or not enough regarding to see real strength ?!
E.g Kookaburra v3.10 via 1000+ games and Unique suite is
Performed as best of best!

Plus via ongoing unofficial test, we can check also
About what will be the Elo Difference e.g via Unique:
All players Elo were less than 10 Elo, exc. Hypnos which
Performed about 25-30 Elo worse than most Top engines!

And I wonder as well, for example, now:
Stockfish 020425 dev. will manage to be Champ?!
Since SF team is highly engaged on tuning etc.
Via various UHO suite series...

Btw (for anyone missed, interested too),
The previous test (via UHO 2022 8mvs +170-179 openings):
https://sites.google.com/site/computers ... t-nn-cs-56

And meanwhile, SCCT (from all independent organizers) seems to be
The World's 1st engine rating, which used to play via UHO openings:
https://sites.google.com/site/computers ... testings-1

And here are the latest results (after 140+ games per player):

Code: Select all

Rank Name                          Elo     +/-   Games   Score    Draw 
   1 SF-X 130425                    36      41     144   55.2%   47.9% 
   2 Omega MPV                      24      40     147   53.4%   49.7%

   6 Corchess 210325                 5      32     147   50.7%   67.3% 
   7 Artemis 12TR                    0      38     147   50.0%   53.7% 
   8 KillfishPB 110425             -19      35     146   47.3%   61.6%

One thing more,
In the end, to see all Whites + Blacks performances..
I hope to create General statistics of both tours too!
E.g with Unique and UHO opening suites

BREAKING NEWS
The Unofficial test (with UHO 2024 BIG +0.80 +0.99 openings) is ended..
Where even with more critical lines, Kookaburra is again NUMBER ONE!
But Stockfish 020425 dev performed below than expected..and who knows?
Maybe min 10.000+ games (per player) required, to see real SF dev strength?
Btw, with Unique suite: SF dev performed so good..almost same as Kookaburra!
On other hand, 2nd SF-X 130425, 3rd Corchess 210325 and if we are going to
Compare other stats, HypnoS is again in last place but as main difference is
80+ Elo diff. than 1st and last place, where the rest players about 20 Elo..
I mean there is much diff. if comparing official tour (with Unique suite)
Anyhow, UHO 2024 BIG +0.80 +0.99 seems to be not bad suite..besides
Not so Drawish, as we see, with av. 57% draw ratio, really not high!

The Winner: Kookaburra - My Congratulations to DorsZ, SF team too!

Thank you very much, Sedat, for your incredible work.

However, without detracting from the work Dorsz has done, this contradicts the metrics on the following page.

Something doesn't add up.

No offense to anyone: https://nextchessmove.com/dev-builds

Dear Anton,

You are welcome and nice to read your valuable comments!

On other hand,
If you are meaning regarding the test via UHO opening suite,
You've right such as SF dev improvements did not work much!

But in the Official tour (via Unique opening suite),
SF 020425 dev. improvement seems to be better...!
Otherwise I hardly doubt to be ranked in 2nd place!

By the way,
if you're going to ask my view: why SF performed worse via UHO?
It's hard to know the true but often SF team's pre Elo diagrams,
- Does not reflect much to reality...at least under SCCT's cond. !

And just a few more words about SCCT conditions,
Hyper-Threading disabled, Large-Pages disabled,
Almost daily speed benchmarks to see stability, plus
Hash-table tests done, e.g to see which is best etc.

In other words,
Instead of SF' Team Elo diagrams, I'd prefer to rely mainly on
SCCT Hardware, Tournament Conditions, Improvements etc. !

As FINAL Conclusion:

1st of all, it is ALWAYS your CHOICE and
You can appreciate any standıng which you like more !)

But anyhow, according to my experience:
Definitely the standings via Unique suites represent better, more
Useful data (than UHO suite) to our actual chess reality... and why?
Because no so HUGE Elo differences between these Top engines!
Note: Sure here I refer about the Elo diff. for the test via UHO suite..
Moreover, Chess is a game for two sides..fl not clear: not mainly for 'Whites'!
As clear proof, please check UHO's win. percentages...almost all by WHITES!

What I can say more,
-Via Unique openings: better quality, more correct, safer!
-Via UHO openings: more FUN, more exciting, but a mystery
Eng strength, especially if the number of games is small !
For this, it's required many thousands of games (per player)
Otherwise, just a waste of time...because 'time' is money!

That's all for now and thanks for your interest... )

Best,
Sedat
