P.S. I just noticed the text accompanying your post! Thank you so much for the credits and for introducing Luna to the community.

I am very curious about the two code corrections you mentioned. Could you share what you had to modify? I would love to patch those fixes into the official GitHub repository!

The previously mentioned modifications – for using nnue in search. Additionally: 1. the correct name is `luna_52000_safe.nnue`; 2. place all `.rs` files in a folder named `src` (for correct compilation).

Thank you so much for the clarification.

You are completely right. Missing the src folder structure was an oversight on my part when setting up the repository layout. Since I've already published the first release, I will push an update to reorganize the files into the src directory immediately so that cargo build works seamlessly out of the box for everyone.

I will also make sure the NNUE filename is properly aligned and documented.

Thanks again for catching these issues and helping me clean up the repository!

THANK YOU for your chess engine !

A bit of fun (actually, a lot) in my RUST_TOURNAMENT. A terribly aggressive chess engine (I'm not kidding)!!!

.....a new engine (Rust).....by Daniele Marpino (Italy)..... two code corrections......a new compilation....NNUE-based evaluation chess engine......& co.......

I changed the name of NNUE in main.rs to the correct one.
Compiled with :
set RUSTFLAGS=-C target-cpu=native
cargo build --release
Now it loads the NNUE. These are the results

PLY - a very modern, interesting engine, currently in an early stage of development. Author: Artin Azizi. The NNUE infrastructure is already well-established. An engine to watch!

Just compiled and introduced in my tournement a nice and vey new Ukrainian NNUE-based evaluation chess engine.
