OK! I've also included the latest version in the tournament. I'm curious by nature.It seems that in version 20260105 you messed up applying the Stockfish patches. Tell me, please, if your engine is so original and powerful, why doesn't anyone test it (CCRL, CEGT, SSDF & so on)? Are you questioning their professional ability? Some forum members are reputable professionals in chess engine programming.
Version 20251221 I really like how it plays! For the latest version I used an old logo made by Graham Banks.

The situation after 204 games:

I have mentioned in my DON post...
there a bug which i have fixed now..
I think you downloaded the bug version.

so download again.. the latest version.. then tell me..

Thanks

If you still think it is still a clone.. then I can't any thing.. speechless.

DON is on github.. from 2007.. No one notice and tested. is it my fault?
Thanks

ChatGPT conclusion:



I like a lot the version 20251221. Even the latest version of Stockfish barely escaped in 2 games. Now it is the only one in 1st place (and one game behind).

He clearly said not a clone.

you can see my initial commit also from 2007.

there nothing bad taking idea from other engine..
on that time Marco also taken and impelemented ideas from DON.
there is 1-2 Commit also he did mentioned DON.

so I never mind if some one took the idea..!!!

it is upto the developer how they implement it.

Thanks

The situation in my short test after 220 games:

When did i deny it ?
It is also written in my each .h and .cpp file..
if you ever read the code.
But it was done initially @2007.
latter on development is seperate.
you can see commits.

and still .. if it is a copy .. then how it is better?

Thanks

I guarantee you, if you run 100 tournaments,

each time DON will be at the top in any time control.
For every time control, DON is ready to compete with different strategies.

If you have any doubt, run another tournament.

Thanks.
