ProteusChessSF - Developing my Stockfish 14.1 Polyglot MTCS derivative

[AlexChess]

Good results of Proteus Chess SF v003 AVX2 on blitz games 3 mins + 1 sec /all with powerful hardware: Ryzen 9 3900x!!!



With my last changes, v003 is rock solid against latest Stockfish-dev (no loses)

There is still a huge strength difference between SF & derivatives and best original engines (Ethereal 13.50 github has NNUE disabled by design)

Zahak 9.0-Android (unofficial derivative) seems a little stronger on my tests (Android games at signature link), probably due to a better optimization compiling it.

[AlexChess]

ProteusChess v004 will have more modifications over the original (trying to make it more aggressive, but I'm already happy with it )

Differences between ProteusChessSF v003 and latest Stockfish-dev with new Sopel NNUE

[AlexChess]

Hi!
Image links on all my previous posts are strangely broken and since my edit time is over, I cannot replace them.
So for new posts I'll use only my server not editable, like on 4 previous posts.
You can find broken images and posts of v001 & v002 builds here: https://banksiagui.com/forums/viewtopic.php?p=124#p124

Note: Differently from what somebody thinks, here I don't only publish test games, but also developing ideas a technical issues.
If you don't like what I doing, please do not read and do not spam my topic, simply ignore it!

I'll answer to all meaningful comments and suggestions

I'm interested in deep search because I'd like to add patterns to pawn and pieces sacrifices to gain a superior or winning position like Carsen and GMs do and schemas to attack castles. Sometimes I perfectly see a draw with my 1900 ELO while even top engines continue to play until 6 man Syzygy tablebases determine that the game is over.

Very interesting game between Proteus Chess SF v003 and dorsz's Blue Marlin 14.8

Black Marlin attacks Proteus castle that counterattacks on the other side. Nobody can overbear

Modifications over previous version are related to pawn structures for a more aggressive play style.




Next test is against latest Stockfish-dev
