Dear Chess Friends,

And as usual, I'm pleased to announce that,

Here is another new GUI/Engine competition!

1st of all,

The idea is born after both tournaments: CS VI / Candidate

And later, I realized to see what happens via more games

On other hand, really it is as mystery which GUI produces

The right and more accurate results.. frankly no any idea, 

But it's clear that Cfish 030820 or CF EXT 291020 suffers...!

Sure probably the programmers will explain better than Me

But anyhow..for example according to my experience,

After comparing... the results are really different..sure

We can not expect exactly same/identical points...but

It seems, there are serious influences. factors etc.

Where as we see the Elo differences are about 10 Elo

And I don't think that due to Error margin...because

Especially 2 core test contains 1238 games (per GUI)

Btw, for better cond. each opening is played as twice!

I mean, here the openings can not be as the reason..

Meanwhile, without to not mention this I can not as well )

I know too that any engine performance is highly depends

On our used openings..but I was not aware so much that

GUIs can play some role over the engines strength too !

Note also that,

     For both GUIs are installed different engine exe copies

     (Both GUIs are not used to play from same engine exe)

Ok... here are the latest played GUI / Engine results:
