The first chess engine written in Python using NNUE. Thank you!

I didn't include a build of the nnue version as it played weaker than the normal version in testing.
I'll add it back to the download package later today so you can do your own testing.

THANK YOU !

Sorry it's really buggy. Not worth messing with. It doesn't work even when running with python interpreter.
I don't know how I got it running before.

Try running the python src with the nnue file 'python sunfish_nnue.py tanh.pickle'

then type
uci
go depth 10
or
go infinite

and see what happens

Jim.

PyTuroChamp by Martin C. Doege
https://github.com/mdoege/PyTuroChamp

Not a new release but a new compile.

Compiled from python src to native Windows executable using Nuitka >
https://nuitka.net/doc/download.html

You can choose many different modes/algorithms. 'Adapt' mode looks very interesting.
Engine will adapt it's strength on the fly to match opponent using 'Stockfish' as an 'oracle'.

Titan 1.0 (New) by Jeffrey Powell (USA)
A very strong (probably already top 20-25) program developed since end of '22.
Tested in an own OpenBench instance
https://chess.drpowell.org

A close version compiled by me was already playing in Carlos blitz tournaments here:
forum3/viewtopic.php?t=83657

In a recent own test with (just) 1200 ultrafast games it came just around 100 rating points below Obsidian 12.0.
(results and pgn in my download - this was a version slightly before release, but release version increased nps by roughly
10% due to some last code changes!)

As there are no win compilations for now, I made an avx2 and a sse4.2/pop compilation available.
