Raven is a chess engine written in C that uses the UCI protocol. Rating JCER=2705 ,   Author: Steve Griffin New Features Search: No null move verification when game phase <= 70. Increase reduction if sort score = 0. Decrease reduction if sort sore > 0. Only futility prune when sort score = 0. Limit LMR of pawn moves to one ply. Time management: Less aggressive early exit from search due to low time remaining (changed from 4 * previous search time to 2 * previous search time). Changed from clock() to tp.tv_sec. (Thanks to Stash author M Houppin for this change). Binaries are available for Windows and Linux (only tested on Ubuntu). Raven 1.10 download

Raubfisch is an engine derived from Stockfish and Torpedo 1.1 XJR (private engine by Frank Karl Werner and Max Fehler).  Rating JCER - 3266 (2st place) If you want to use the neural network provided with the Raubfisch engine, just copy and move it to the same directory as the engine. The engine will then be able to recognize the network easily and thus communicate with it. However, it is advised not to rename the network provided with the engine. However,if you want to use another network of your choice, please specify its path in the Uci and make sure its name is exactly the same as the one in the uci. See screenshot below: To make sure that the engine recognizes the network provided with it, double click on the Raubfisch.exe executable, and read the info string such as the one displayed in the see below: Raubfisch X44 and GTZ23 NNUE for Android - download

RubiChess -  UCI chess engine, Rating JCER= 3056 Author - Andreas Matthies This release besides some minor improvements introduces NNUE evaluation to RubiChess and with this some more binaries: RubiChess-BMI2: For best performance on modern intel CPUs and probably also new AMD Ryzen Zen3 / 5?00X CPUs (tests welcome) RubiChess-AVX2: For best performance on modern AMD Ryzen Zen/Zen2 RubiChess: For older CPUs that support POPCNT but no AVX2 RubiChess-SSSE3: For even older CPUs with SSSE3 but no POPCNT RubiChess-Legacy: For very old x86-64 CPU without SSSE3 support (are there any?) You will get a warning at startup if the selected binary doesn't match your CPU or it will just crash. NNUE evaluation is disabled by default. It can be enabled by UCI option "Use NNUE" and it uses default network file nn-803c91ad5c-20201107.nnue which is part of Windows package and for download at https://github.com/Matthies/NN Rubichess 1.9 stable NNUE - download
