Hello Chess Friends,

As usual, I am pleased to announce that,

Another new NON-NNUE CS of 3600 series!

For anyone missed, the previous tour: Results

1st of all,

The current engine championship is played as Ponder ON

And mostly of the games are played mainly under Cutechess

And as alternative chess GUI: Banksia 0.53 used to play too

Note also that exactly with the same players under Banksia:

I organized another tour, in short all same exc. as Ponder OFF

But due to many many time forfeits, the results are not published..

And it seems Banksia GUI is buggy, no any idea what can be the

Reason, maybe the option 'Concurrency': 32 made a bad role ?!

E.g in case of Concurrency 16: no any time forfeit is recorded...

I mean as Ponder ON, all worked flawlessly...but I can not say

Same words when I switched to Ponder OFF..really very strange

And very sad that a lot of my free/CPU time is gone for nothing...(

By the way, another waste of time is that:

Two testings cancelled: Black Marlin 15.1 and BlackDiamond 13.1b

The reason, for example as NON-NNUE both engines suffers a lot..

Black Marlin's performance was minus plus at 10% win. percentage

Where via Black Diamond: this engine lost all his played games...

No any idea about why they cannot play properly without navigation...

And I hope in the next releases to be fixed these bugs...otherwise

Any engine name, which is starting with BLACK will be out directly ))

And finely, after long period of time (approx. 2 years):

Cfish 030820 engine is not ranked as Number One...

And as I stated before, no one can stay on Top forever!

However, Cfish engine is very dangerous for sure...and

I would not much surprise... if again will be not as No 1...

Because 400 games can be counted as good data, but

Not enough, e.g 1000 games (per player) would be ideal..

On other hand, nowadays almost summer..time for holiday)

That's why I don't want to promise to run all these games...

But anyhow, the current good news is that,

This time, we have 3 new Leading engines and as far as

I remember, this never happened before..very interesting...)

Champions: Kayra, SF200620MZ, SF Polyglot - Congrats to Winners!
