20. Mar 2024: After getting a lot of letters from all over the world and some other people also being dissatisfied with Stockfish dev, I decided to release another engine. The meaning is: The influence of the small network was reduced and the large network was implemented with dimension 3072 (instead of dimension 2560). I use this engine for Blitz and Bullet as well as for quick analysis. I prefer to use the large network on Lichess because it allows me to win more games against weaker engines because it values fewer positions 0.00. There are fewer threefold repetitions. This means that such games run longer! Of course, you can only win if your opponent makes mistakes. Weaker engines also make mistakes in positions that are drawn and with more moves per game there are more mistakes.

Implemented features "Minimum Thinking Time" and "Slow Mover". By the way, new D 3072 nets are currently being tested every day: https://tests.stockfishchess.org/nns. You can use these networks with the engine by copying the network into the folder and replacing the large network in the engine options. Have fun!

Thank you Eduard !

22. Mar 2024: Big-SF 210324. Latest SF updates and improved search for the large network. As I already wrote, the SF developers are testing new D 3072 networks. Here is a test version with the network "nn-56e7225a7727.nnue". The network is now embedded because some users are having problems with external networks (even though it's easy). Features: Slow Mover, Minimum Thinking Time. Download Win 64-Bit (avx2, bmi2, sse41, source code): https://pixeldrain.com/u/vqWuhCtX
