You have declared that you are a skilled, certified and experienced C Developer, why not using it in a challenging project and show people you are a competent Chess Developer??

There are so many rating lists here that I do not think that adding a server list from an intense and cloned engine is interesting for people. Even because there is no traceability of the modifications you might have performed on the cloned engine.

What is the point of the bloodiness? I am not disrupting whatsoever you do but I try to understand the added value.

It is also Ok too. I do understand your approach; probably other people came to propose the same ideas where to spend your time and cpu, and also got ignored. Thanks.

Right now I'm only testing the original source of Rubichess, to plan what I could change. On more games it uses all the time available, also on 25 minutes TC. On sudden death matches that is bad... Most games lost only by time.

I will try to fix that on my derivative.

ProteusSF-Aureo 240405 Core2 Duo 2.4 Ghz (130 kN/s) vs Rubichess 240112 8 CPUs (7.3 MN/s) Result: +4 / 22

Watch the live!

Armageddon Handicap Test (1/75 of Rubichess computing power) Classical 25+1 games completed.

Now I switch to Ethereal 14.32 github tests.

I expect a better performance by ProteusSF-Aurora 240405 since Ethereal strenght without NNUE is extimated 2500 Lichess.org ELO :)

Many thanks to No-Stockfish-Bots to accomplish to my requests, letting me to choose the opponents.

I agree you "could be useful to fine tuning their work". For example, do a tweak then test at STC, LTC & VLTC using a statistically a sound method; e.g. CuteChess SPRT. If your results were positive developers would welcome your ideas with open arms.

I like Ethereal 14.32 github ! Despite the fact that it hasn't NNUE, it is very strong and solid. We must obviously consider that this engine is running 50 times faster than Proteus-Godot on my old 2008 Core 2 Duo 2.4 Ghz, but until now I have won only 3 games against it.

I think it will be very interesting to mod this very good code and I will learn a lot from it, even if classical evaluation is deprecated! :)

This is one of ProteusSF-Godot's won games, with white:

Note: If you watch the Lichess.org games history, Ethereal has won 1 game and lost one by time, but it was due to lost connections in draw positions.

After 36 long time games 25+1, even if Ethereal 14.32 performance is a little worse compared to the beginning of the test, +11 / 36 matches what I was expecting and I still think that is very interesting to study it to learn all the modern chess coding techniques. Probably it is the best open source engine without NNUE, so for didactical purposes and historic archives about the no NNUE era is perfet. I will now compare it with Etherlito (first Grant's trial about NNUE) to verify if, after 2 years of development, classical evaluation has reached the level of the rudimental 2021 NNUE boosted engines.

ALL THE GAMES ON PGN

Note: I have assigned 1/2-1/2 to 3 draw games lost for internet disconnection on both sides.
