Breaking News
I realized the tour to be ended...normally I was planning to be active longer
The reason, I tested 2 newer releases, which performed worse than previous..
In short, it is a pity/waste of time, when new ones are worse than old ones!
Note: I am referring about played results: Minic 3.02 and Lc0 v0263 67223
Sure, I hope to test still engines+NN file, but in case of creating a new rating..
Probably I will use faster time controls...

Breaking News
The main target was testing only Top chess engines via NN Evalfiles
Note that the database has no any game lost on time, just impressive!
Because looking at NON-SCCT results, frequently I see time forfeits
In other words, that shows even at 3min: the 'Stability' is not so bad...

Latest Update: 31.01.2021


Hello Chess Friends,

I am pleased to announce that,
I've organized new handicapped competition!
In short, it's similar tourneys as 2019 / 2018

Meanwhile,
I plan another new series of handicapped tours!
Where the opponents will be close to GMs level
And next time,
I hope to test more Top engines in handicapped mode!
More info very soon...

More details about the current played tour:
This time Stockfish 170121 BMI2 is played:
- Without 8 (eight) Pawns
- Without 1 (one) Rook
- Without 2 (two) pieces: Bishop and Knight
- Without 4 (four) Pawns plus without Bishop
- Without 4 (four) Pawns plus without Knight
- Without 2 (two) Knights

Btw, I used to play the same Stockfish version,
Which. managed to win the recent: NNUE CS IV

As Opponents,
I've picked the engines mainly at around 1600-2000 Elo
As usual, I played the ones which are capable to ponder...
As you know, chess is thinking in the opponent's turn!)

Note also that,
Stockfish 170121 is tested as NNUE and NON-NNUE
And the overall SF's played results are published as:
Stockfish HC NNUE = via nn-62ef826d1a6d.nnue
Stockfish HC = played without any EvalFile
HC = HandiCapped

As final conclusion (under these handicapped conditions):
It seems, Stockfish HC's strength is close to 1800 Elo points
Also, the overall Draw percentage is incredibly very low...
Plus we have new data to compare NNUE vs NON NNUE!
And as we see,
No any influence in strength progress via SF + EvailFile!

Dear Chess Friends,

I'm glad to announce that,
I've started another new handicapped competition!
It's similar championship as CS I / 2019 / 2018

The main difference is that (about the new tour...),
1.The opponents strength are close GMs level
2. More engines are testing in Handicapped mode
E.g I managed to include over than 80 engines
Approx. 75 engines are close to GMs strength
And so far, I tested Top 5 engines (as Handicapped)
Sure, still a lot of work required, because to create a new
Rating with 80+ engines, not not so easy...as it looks !)
Due to many engines are not tuned or suffer under these
Handicapped conditions...e.g LCZero is one of them!
That's why unfortunately I paused/cancelled testing Lc0 ...
But I have good news as well,
There are many chess engines, which work flawlessly...

Meanwhile,
For anyone who missed...regarding the current ideas:
Handicapped engine rating lists are never seen before!
The same words are going for my book competitions too...

More details about the current active tournament:
Top engines played with 4 Handicapped openings:
- Without 3 (three) Pawns
- Without 4 (four) Pawns
- Without 1 (one) Bishop
- Without 1 (one) Knight

And please stay tuned...probably today or tomorrow,
I am going to publish the 1st played results of Top 5 engines:
Ethereal, Houdini, Komodo Dragon, SlowChess, Stockfish


Best Wishes,
Sedat

And very soon, I am planning to test more new Top engines
E.g just only a few of them: Eman, SugaR, Raubfish etc.
In short, I wonder much,
About what will be the influence of their engine learning...

And here are the 1st played results so far (in Handicapped mode):

Dear Chess Friends,

I'm glad to announce that,
I've organized another handicapped competition!
It's similar championship as CS I / 2019 / 2018

The main difference is that (about the new tour...),
1.The opponents strength are close GMs level
2. More engines are tested in Handicapped mode
E.g I've managed to include over than 80 engines
Approx. 75 engines are close to GMs strength
And I tested so far Top 10 engines (as handicapped...)
Sure, a lot of work, efforts...are spent, because to create
New rating with 80+ engines, it's not so easy...as it looks !)
And all the mentioned job is done in very short-time of period!
Note also that some engines are not tuned or suffer under these
Handicapped conditions...e.g LCZero engine is one of them!
That's why unfortunately I paused/cancelled testing Lc0 ..Btw,
Ceres v0.87 (plus previous vers.) did not work on my machine...
But I have good news as well,
There are many other stable engines, which worked flawlessly...

Meanwhile,
For anyone who missed...regarding the current new ideas:
The 1st ever created rating list via Handicapped openings!
For example, such engine rating lists are never seen before!
And same words are going for my book competitions too...

More details about the current active tournament:
Top engines played with 4 Handicapped openings:
- Without 3 (three) Pawns
- Without 4 (four) Pawns
- Without 1 (one) Bishop
- Without 1 (one) Knight

As final conclusion,
I decided the current exciting competition to be ended...because
The other rest available engines have no BIG chances to win....
But note also that there is a possibility the tour to be resumed...
Regarding the performance of some engines,
It seems, Eman and SugaR's engine learning are played a BIG role!
Komodo's performance is not bad as well..., and no big surprise...!
Meanwhile, I picked especially Rybka 1.2f (as high-rated) because
Rybka was the 1st engine, which reached 2900 Elo (in 2005-2006)

The HC Winner: Eman, SugaR - Congrats to Omar, Zerbinati, SF Team!

Latest Update: 19.02.2021

Hello Chess Friends,

As usual, I am pleased to announce that,
A new book competition is started...!
This kind of tour is different than all...

Some Tournament Details,
The deep books will be played by NON-NNUE (close to 3500 Elo):
asmFish 250817, Houdini 6.03, Komodo 13.3, Stockfish 051217 etc.
Where the books opponents will be Engines+EvalFile+Perfect 2021

In short, I hope to test:
NON-NNUE (av. 3500 Elo) vs NNUE (av.3300-3700 Elo)
E.g NON-NNUE+Deep openings vs NNUE+Short openings...

To be more clear,
The idea, the target of running this kind of tour is born due to,
NNUE /Evalfiles are with clear advantage over NON-NNUE...
For example, as I said before in my recent organized Duel
Many testers prefer short books for NON-NNUE vs NNUE....
E.g NNUE engines gain in deep openings, middle game etc.
Where NON-NNUE gains mainly up to 5-8 moves....
So...running with similar conditions: is it much fair...?...
To be honest.., I do not think so....
At least with the new tourney...we will have chances to see
NON-NNUE engines under better and more fair conditions...
Because, NON-NNUE engines will be played via deep books
In other words,
Now it's just opposite....NON-NNUE via deep opening lines...
Where NNUE engines will use Perfect 2021 opening book
You may know, this small book is not so deep in opening lines!

Plus we will be able to compare:
-The Elo differences with various books!

Btw, who knows?! perhaps after the end of tournament...
I can create a strong deep book (for Top NON-NNUE engines)
Also, this book can be useful for engines without own books!

Meanwhile,
For nowadays, the ongoing CS L is planning to be still active...!

And ,
Please stay tuned...and do not miss the current exciting tour...!)

More info very soon...

Best Wishes,
Sedat

I realized about current NNUE IV Championship to be resumed...
The main target is testing only Top chess engines via NN Evalfiles
Note that the database has no any game lost on time, just impressive!
Because looking at NON-SCCT results, frequently I see time forfeits
In other words, that shows even at 3min: the 'Stability' is not so bad...

NNUE CS IV Leader: Eman - Congratulations to K. Omar / SF Team!

The competition is ended...and the winner is Eman 6.91 engine!
However, it's clear that almost of the players are close in strength
And let Me say some words over these tours with players of 3600+
Yes...almost all of them are based on SF....and as I stated before,
These tours remember Me past e.g as Chessmaster players settings...!)
Plus.3600+ Elo testings are useful for my Balsa, Perfect book's tuning!
Note also, finely 2 engines (Heka SF+ Komodo Dragon) lost on time (
Anyhow, looking at NON-SCCT results, frequently I see time forfeits
E.g in tmy latest book tours via SF based engines: no any time forfeits!
Note that I'm talking about stats with over than 200.000 SCCT games...
In other words, that shows even at 3min: the 'Stability' is not so bad...

• Mostly of the participants are played via nn-62ef826d1a6d.nnue
• Fat Fritz 2 engine is the free version (played via FatFritz2 v1.bin)
• As usual, all engines are 64-bit, BMI2 is used, where available...
• For Better Engine / Hardware Performance:
- HT OFF, LP OFF, Book Learning ON, Ponder ON, MP etc.
- Btw, each player is used to play from other engine copy and book

Hello Chess Friends,

As usual, I am pleased to announce that,
A new book competition is started...!
This kind of tour is different than all...

Some Details,
All deep books are played by Houdini 6.03 Pro x64-pext
Which is NON-NNUE and Houdini 6.03 is close to 3500 Elo
Where the opponents are Engines+EvalFile+Perfect 2021
Probably later....I hope to test the Number One book via:
Komodo 13.3 or Stockfish 051217 too...

In short, my main target is that,
NON-NNUE (av. 3500 Elo) vs NNUE (av.3300-3700 Elo)
E.g NON-NNUE+Deep openings vs NNUE+Short openings...

To be more clear,
The idea of running this kind of tournament is born due to,
NNUE / Evalfiles are with clear advantage over NON-NNUE...
For example, as I said before in my recent organized Duel
Many testers prefer short books for NON-NNUE vs NNUE....
E.g NNUE engines gain in deep openings, middle game etc.
Where NON-NNUE gains mainly up to 5-8 moves....
So...running with similar conditions: is it much fair...?...
To be honest.., I do not think so....
At least with the new tourney...we will have chances to see
NON-NNUE engines under better and more fair conditions...
Because, NON-NNUE engines will be played via deep books
Exc. just for comparing, Houdini6.03 via Perfect2021 played too
In other words,
Now it's just opposite....NON-NNUE via deep opening lines...
Where NNUE engines will use Perfect 2021 opening book
You may know, this small book is not so deep in opening lines!
Btw,
Here the current standings, frankly I 'm quite impressed by Cevdet2 bin
E.g minus plus 90 Elo better than Perfect 2021 book... just unbelievable!
Sure, rest books Katzenmaier M11.3, Alchemist are doing very well too!
Note also that, more books coming very soon.. and Good Luck to all !)

CS LI's Current Book Leader: Cevdet2 - My Congratulations to Cevdet Sarı!

Another note is that, regarding to not affecting book learning of CS L,

Btw,
Here are latest standings, frankly I'm quite impressed by Cevdet books!
E.g approx.80-90 Elo better than Perfect 2021 book... just unbelievable!
That means also, in overall openings Cevdet books are superior strong!!
Plus,

Note also that, a few more books coming soon.. But after the next testings...
The tour is planning to be ended...

Hello Chess Friends,

As usual, I am pleased to announce that,
Recently I organized a new book competition!
This kind of tournament is different than all...

Some Details,
All deep books are played by Houdini 6.03 Pro x64-pext
Which is NON-NNUE and Houdini 6.03 is close to 3500 Elo
Plus, Cevdet2-BIN book is tested via Komodo 13.2.5 too
Where the opponents are Engines+EvalFile+Perfect 2021

In short, my main target was that,
NON-NNUE (av. 3500 Elo) vs NNUE (av.3300-3700 Elo)
E.g NON-NNUE+Deep openings vs NNUE+Short openings...

To be more clear,
The idea of running this kind of tournament is born due to,
NNUE / Evalfiles are with clear advantage over NON-NNUE...
For example, as I said before in my recent organized Duel
Many testers prefer short books for NON-NNUE vs NNUE....
E.g NNUE engines gain in deep openings, middle game etc.
Where NON-NNUE gains mainly up to 5-8 moves....
So...running with similar conditions: is it much fair...?...

At least with the new tourney...we will have chances to see
NON-NNUE engines under better and more fair conditions...
Because, NON-NNUE engines will be played via deep books
Exc. just for comparing, Houdini6.03 via Perfect2021 played too
In other words,
Now it's just opposite....NON-NNUE via deep opening lines...
Where NNUE engines are used to play via Perfect 2021 book

Another note is that, about to not affecting book learning of CS L,
New/separate fresh book copies are installed...(for current tour..)

Meanwhile, just I'd like to add,
Perfect 2021 book is not optimized over similar book matches ...
So no BIG surprise that any well-tuned deep book performs better...
Sure, in case of using close in strength engine for all books!)

Btw, the reality is reality, actually this is already known...
For example, in case of various openings e.g up to 8 moves:
Then usually Perfect opening books's performance is one best!

As I stated before (for anyone who missed about Perfect2021):
Not so deep in opening lines, just mainly up to 8 moves!
Recommended to be used as same book for all chess engines...
And it can be a good choice to determine any engine strength!
Plus Perfect2021 prefers to play a lot of various openings...
What does it mean in chess? a long story...but I will try in short:
The strongest opening theory is quite limited, not so various!
In other words, I can increase the strength of Perfect 2021 book
But then, I'm afraid we will see minus plus 10-15 main openings!
Plus in that case, the engine testings would not be much boring?!

A few more words about the current played deep opening books,
They are not so much various in openings...their target is very simple:
To win...and all of them prefer mainly the strongest trend openings!
That sounds perfectly fine to Me.. the best way to get more points!

Here are final standings, frankly I'm quite impressed by Cevdet books!
E.g approx.80-90 Elo better than Perfect 2021 book... just unbelievable!
That means also, in overall openings Cevdet books are superior strong!!
Plus,
Cerebellum, Katzenmaier, DON, TrendMoves etc performed very well too!

CS LI's Champion: Cevdet2-BIN - My Congratulations to Cevdet Sarı!
