Hello Friends,

Meanwhile (for anyone missed, interested...):
Here are some info, which can be as useful tips
To see about which test conditions are best...

1st of all,
It's not bad idea to run own strength testings!
In this way, you will have a chance to see....

Sure and as we know (since 2020, NNUE on scene),
The situation is not same as before...but however,
Running some serious pre-strength test would be not
So bad idea..e.g Draw, HT, Hash, Learning etc testings!
Even some compile strength testings you may run, e.g
Bmi2 or avx2 or avx or popcnt.. may perform better!
Or running a Draw test, sure depending on cond. but
Some NNUE engines may produce less draws..that
Means in same time.via best optimal cond., you may
Get higher points..or just opposite..for this reason:
Once more I say, please run your own tests,
Sure I am referring before playing serious tours!

Btw, as I stated earlier:
In case of using Large pages ON, be careful please!!
Sure it all depends, but if we are running long-matches...
We can not expect so much accurate results, for more info:
https://learn.microsoft.com/en-us/windo ... ge-support

By the way,
It's my pleasure to share my experience with all of you!
E.g when I was as online player (on Playchess server):

1. Hyper-Threading (SMT) was as disabled on my hardwares!
As reason, I've noticed that Rybka is performed better..!
Otherwise, not only Rybka, plus some other engines suffered,
I mean if running Ponder ON via Hyper-Threading as enabled..
2. Large Pages were as disabled on my operating systems!
3. My used Rybka engine vers were played via 128 MB hash

Exception the above important influences, you know that
For better performance, it's required also fast hardware!
Plus super strong book too, but via frequent book updates!
Otherwise, I think that no chances to be one of Top ranks!

What I can say more (about during 2008-2009 years),
Frankly, before entering to be as online player etc.
I've played many serious book strength testings!plus
I created newer strong lines that never played before!
And I noticed later (during online) the opponents were
Out of earlier of books, where my book was continued
To play in deeper opening lines...sure as a result,
In most cases, these new lines played as main role to
Get better points...

Sure there many other techniques...but that's all for now!
And I hope also that my current experience will be helpful!

Thanks, thats what i do as well on the issue of books. I don't depend on gathering games alone, I also create mine with my engines + engines of others.

You are welcome...

And plus enormous efforts are required...!
In same time means, never ending process!

Good luck )

Hello Chess Friends,

I'm pleased to announce, new Duel is started:
SF-PB 160823 avx2 Vs CorChess 140823 avx2

And so far (after 173 out of 310 games):
Current score: +10 Elo (in favor for SF-PB)

Note that current test idea is born after checking
Oliprog older test, where CorChess managed to win:
https://chess.massimilianogoi.com/forum ... .php?t=140

Sure I've done my best to adapt to Oliprog testing..
And I can't say that our both used cond. are same!
At least I can say, now I test newer eng versions!

But anyhow, I think that sometimes...
It's worth giving a try )... more better, right ?)
Plus now we'll have new data for comparing!

By the way, SCCT conditions:
2x EPYC 7B12, Windows 10 x64, HT + LP Disabled, Cutechess,
1 Core, Ponder ON, 2m+1s, Unique 170623,128 MB hash, 4-MEN

Oliprog conditions:
AMD A10-9700, Windows 10 x64, HT + LP Enabled, Fritz GUI,
2 Threads, Ponder ON, 4m+1s, Unique 170623, 1 GB hash, 5-MEN

In other words,
Our both used cond. differences are more...but
Same of our used conditions are exactly same!

More info soon and please stay tuned )

Best,
Sedat

Many thanks!

Best regards.

SCCT Duel - CorChess vs SF-PB is ended:
About +7 Elo (in favor for SF-PB 160823)

The Winner: SF PB - Congrats to Skynet, SF team!
The Overall Draw-Ratio (based on 310 games): 95%

GAMES:
https://mega.nz/file/OpxS1a4A#T_CAhwxYR ... SHNpWoz6Zs

More Details,
It's clear that the overall draw ratio is increased!
Actually nothing strange...reason, SF team seems to
Be working on optimizing over Evalfiles, plus since
Unique 170623 suite is publicly available so I assume
That is easier vs current opening lines (to be tuned)
E.g as reference/evidence, when current openings were
As private..then the overall draws were about 85%-90%
E.g now, as we see the overall draws are close to 95%
I mean, Unique openings are became drawish as Balsa!
Btw, I have to keep next newer Unique ver as private)
If nothing else,
We'll see more fun for sure...at least for my side!

As final words, it's clear also that:
Mostly of SF-PB vers perform not bad via SCCT conditions!)


Best,
Sedat
