New chess Engines clones and News 2021

Soviet NN 2021 (Russian Federation)

An appreciated return from 2019, it disappeared and returned in 2020, but wasn't anymore compatible with my system. I remember the not NNUE version as very strong. Just started testing the latest build with NNUE on my SuperBlitz, new results very soon

This engine is a clone of Raubfisch and does not even have a source code. I suppose you got this engine from cloner and renamer Solidor. He is known for exactly that renaming engines. He is not a programmer but a clueless moron who know nothing about programming.

From Chess2u:

It´s a clone of Raubfisch X, but with SOLIDOR net, strong, tactical, aggresive...Very nice, thank you!!

Since it's a clone of a not GPLv3 compliant clone... no problem for the Raufbisch fake authors. If they release their modified source code, they can defend their property.

That is actually not how it works, it is not Raubfisch who may ask for his rights, but it is Stockfish, because Raubfisch is legally a property of Stockfish, even if the cloner doesn't admit/respect it

Dear Amanj,

I know, Raubfisch authors should made their strong engine GPLv3 compliant attributing the original work to the SF team, then Solidor should do the same to both. As explained before, I'm not sharing illegal engines, but only privately testing them for statistical purposes, and this is allowed.

PS: I'm still waiting Zahak 7.0 + NNUE + Polyglot support. I think that on very short blitz TC (bullet-like) your actual engine is already competitive, but after a preliminary test on +-15 mins /all TC isn't still 3000+ ELO. I support all friends here and ASAP they score some points (+- 10%), I'll insert them in my SuperBlitz. I'm already testing beta engines, like Coiled and Combusken that have been kindly compiled/patched for my system by their authors, and if you want I can do the same with Zahak 7.0b.

Best regards, Alex

Ethically and legally speaking this is not true, but SF has little interest/money to spend every minute/effort on everybody to correct the issue

...Since yesterday, and I don't follow the topic where you have posted the announce anymore.

I don't find the net to add to 7.0.

The default net is embedded, but if you are using BansksiaGUI, I had to fix a UCI issue with that GUI in version 7.1:

Someone with an anonymous Brazilian email
has sent me a new SF derivative engine that seems very strong!

Você poderia testar o EtherFish 14,25 NNUE RIO ARM64?
Mix do Ethereal 13 github, Stockfish 14 + Private NNUE RIO
Por favor, não compartilhe até que eu o lance na GPLv3.
Muito obrigado!

I have only a binary for Windows11 ARM64 with NNUE embedded,
and he ask me to test it privately not sharing it until he will release
it under GPLv3 license. But I can share results, games and the nice logo

EPIC LOGO!
