Thanks Sedat. Congratulations to Patrick Leonhadt. Plentychess is one of my favorite engines too. Although different binaries of engine show really different behaviors. For example Plentychess ( generic) plays in different style than Plentychess (BMI2). But totally I like this engine and it’s moves.
Best regards

Not at all, and thanks for your interest dear Homayoun )

Yes..it seems that PlentyChess is came from other planet,
And so far this great engine destroyed everything on field!

Btw, you may noticed, just only in CS IV managed to be 3rd:
https://sites.google.com/site/computers ... apped-cs-4
But all in the rest bullet tours: it's a Winner...In other words,
This is not a luck etc. sure in current tour, still not 100% clear..
You may know, after 1000+ games... everything may happen,
Moreover, via this tour: we will have more 3700+ Elo entries..

On other hand, I admit too:
Kayra, RapTora etc. are just as 'beast' under conditions as well...

About Engine exe speed compiles such as Generic, BMI2, AVX2 etc,
You can be right of course...actually it all depends on various processors
Speed architectures, e.g some fast compiles may gain on processors with
Larger amounts of data and in same time that means
It may access more memory, compared to the slower processors...

Meanwhile, about 2-3 years ago... I ran such eng compiles competitions:
https://sites.google.com/site/computers ... g-strength
Where you will notice different eng performances...but this is also true that,
On my tournament machine (2x EPYC 7B12), usually AVX2 seems to be fastest..

Breaking News - 03.01.2025:
Well via this update 16 engines are entered, some of them are former Champions..
And frankly I'm satisfied by the performances, at least by many...I assume for your
Side too ? But I admit that newest SF ones suffer....e.g not as best here and why?
And I wonder much, what is the opinion by SF experts? I mean that the older ones
Are doing better...in my understanding: newer versions should be stronger, right ?
And just imagine: Morphy (19th century player) is stronger than Carlsen (of 21th...)
Who knows?) if Morphy were brought to our present day then the Legend would be
Capable to beat any strong human chess player on this planet..On the other hand,
If you ask my view about why newer SF releases suffer..., I think that it all depends
On NNUE assistance, such as if your trained data is stronger..then situation may be
Different than now..for examples, Kayra 1.7, Kookaburra 1.03, Stockfish 240223 etc
Are much older... but they perform better than Stockfish 17 or than any other which
Released in 2024/2025, strange really..Ok chess friends that's all for now, exception:
I already started testing the best (high-rated ones, which are over than 3300+ Elo)
Where they will be played extra 570 games more (in total: 1020 games per player)
And let's see who will be next Champ..I guess: PlentyChess..sure I may be wrong )
But there is one true: nowadays PlentyChess is trend to be Winner, reality is reality...

Meanwhile (for anyone missed, while we talk about the Legend..)

Here is one of the most famous, greatest chess games in our history !
Where played by Morphy and he checkmated (in 17 moves) his Allies..

What I can add more,
In this famous Opera game, Philidor Defense (C41) is played,
Which is often used to be played by humans.. Btw, nowadays,
Especially in SCCT Tours, C41 is not so frequently played...as
Main reason, Blacks often fall in danger...no much chances
To win..sure I refer for Top Book Authors, where they know
Regarding Blacks may suffer a lot..but in 1858... situation
Was not same as in 2025, right ?)

Code: Select all

[Event "A Night at the Opera"]
[Site "Paris (France)"]

[Black "Duke of Brunswick and Count I"]
[Result "1-0"]
[ECO "C41"]
[WhiteElo "2680"]
[PlyCount "33"]

And I hope you like it and enjoy this brilliant game of Paul Morphy ?)

Breaking News - 04.01.2025:
As I expected, PlentyChess, PlentyChess, PlentyChess is a Winner again and again!
What does it mean? In my eyes, a lot..where another superior performance comes
By Kookaburra, Polyfish, Kayra, RapTora etc. Note that this time I have realized to
Divide into 2 (two) rankings: the ones which played with piece odds (handicapped)
Plus which played in Non-handicapped mode, I think in this way is easier to check..
Btw, as you may see via latest played games + Elo calculations, many of the ranks
Are slightly changed.. (here I refer according to previous gained 3300+ Elo points)
That's why some of the engines are not continued to play (e.g extra 570 games...)
In other words, sometimes not all in my hands ) to be sure, here previous: Results
On other hand, all the Top engines (which played extra 570 games, in total 1020),
In their 2nd test, they used to play via different openings, an improved suite vers.
So some are gained better points some less, actually it seems mostly gained less..
In same time means my created openings are not soft touch to gain high points, in
Fact, if it was easy everyone would do it, but what makes it great? that it's a hard!
And here are general stats (based on 37890 games) White wins: 40%, Black wins:
34%, Draw ratio: 26%, as we see here, there is no any strange, unusual numbers..
Note also that very soon new Blitz MP CS is coming as well, sure with 'best' ones!

HC CS VI Current Champion: PlentyChess - My Congratulations to Yoshie2000!
Note: Exactly the same PlentyChess ver is Champion of recent Bullet CS III/ V

Hello Chess Friends,

As usually, I am very pleased to announce that still
Handicapped CS are ON, very soon results coming:
https://sites.google.com/site/computers ... apped-cs-7

By the way, (for anyone missed) here are some of my best sayings:

“The pessimist focuses on bad games; the optimist on good games;
But all the greatest games of all-time have been played by optimists.”

“There is no greater fault than preferring the weak openings,
Where the strong openings play as golden key to gain points”

“It's pointless, if using just weak openings for Whites or Blacks,
Since chess is a game for two sides, besides the weak lines are
Not useful for majority, at least for the serious chess players.”

“Via weak lines for determining eng strength is needed thousands
Of games (per player,) otherwise the error margin can be too high,
Where via using strong openings, minus plus 1000 games enough.”

The more I learn about engines, databases, the more I know that:
The powerful move is not in date or in size, but in the correct line”

“Moreover, the more I learn about NNUE engines, the more I see:
They are getting closer in similarity, in playing styles to each other”

“If you don't know past, it's not the end, learn from it, but if not:
You are a simple pawn that you don't know it's a piece of chess.”

“Learn from yesterday's mistakes while preparing for tomorrow,
But never give up, sooner or later you eventually succeed it.”

“Never underestimate or overestimate your chess opponents,
Just learn, attack, look for better moves, make plan for a win,
And then no doubt that you can defeat them effortlessly.”

“We can not undo the bad move, but we can learn from it.”

“The best organized tour is what people say you can not do.”

“To see a win (if playing under optimal cond.) by Top engines:
It's like looking for a needle in a haystack, and what's point of
Using BIG umbrella, if almost no any drop rain on the horizon.”

“Be original, be creative, you can not be on Top by work of others”

“No One can stay always Number One but Fun: it may stay always
Alive in our life, actually all it's in our hands, just we have to take it,
And if I've caused regarding all over, then how happy I'm as well.”

“Computers changed, Engines changed, Tournaments changed,
Only my love to Computer Chess is never changed.”

As final words,
Enjoy and have fun with my sayings..!)

Best Regards,
Sedat Canbaz

Breaking News - 06.01.2025:
Just another new tour organized..where this time the Winner: Stockfish, yes, it's a
Mother of many engines, fully deserves to be on Top, congrats and well-done to all
On other hand, in almost all of the tournament duration's time, I expected Kayra to
Be the current Champion..since was as Leader, with highest gained points..but till
To the moment of latest strongest entry (Stockfish) but however Kayra is oldest e.g
Released in 2022, you may know..time is everything to become better / stronger !!
Sure I admit too..if your newest NNUE data contains on weaker moves then not 3
Years older one, but much older versions (in years)... may gain more points easily!
Btw, I've switched to other constant weaker engines, due to Blitz + MP+ Ponder ON:
I noticed serious influences (in favor for constants of 3300+) so later, after running
Some tests (Blitz, MP, Ponder ON, 10.000+ beta games) about determining, which of
Constant engines are suitable for these cond. and only after that I realized to start
Running the official championship and just a few examples: Gull 3 suffered here or
Fritz 16 performed better than expected, plus I may count more..but unfortunately
No much fee time for all...but there is one true: you will never know...until you try!
About PlentyChess: it seems to be a buggy one, if Blitz+ Ponder ON.. e.g I saw some
Time management problems such as half of time control is not used properly, very
Likely Ponder ON issue is played as negative role...that's why, I've preferred the tour
To be played under safer cond. (e.g Blitz, 1 Core and Ponder OFF) Ok chess friends,
That's all for now exc. there will be a new Rapid tour as well where as players will
Be only current Top 3 engines (Kayra, PlentyChess and Stockfish), wishing good luck!
And here are the general stats (based on 2520 games) White Wins: 45%, Black Wins:
36%, the Draw Ratio 19%, as we see here again: no strange or unusual stats numbers..
But I can't say as same words for all other suites which are created by other authors!

HC CS VII's Blitz Champion Stockfish - Congratulations to Stockfish team!

Breaking News - 09.01.2025:
As I promised, finely Rapid CS organized where the Winner is again: PlentyChess!
Yes this great engine is just born to win..no more no less... and proved many times!
Sure Stockfish and Kayra are magic ones as well..all the Top 3 showed us that they
Can be much dangerous in every hard cond... By the way, you may know, with BIG
Assistance, every 'fool' can play stronger, but as 'most important' what about under
Extreme test conditions? Yes here the situation is totally different..not easy for sure..
Ok chess friends see you later and thanks for your interest (for over long past years)!
