Tips on How to Configure Belka 2.0 UCI Chess Engine
Belka 2.0 UCI chess engine has some parameters that you can adjust to customize its behavior and performance. You can access these parameters by clicking on the engine name in your chess GUI and selecting the option to configure it. Here are some of the most important parameters and what they do:
Hash: This determines how much memory the engine will use for its transposition table. A larger hash size will allow the engine to store more positions and improve its search depth and speed, but it will also consume more RAM. The recommended value is between 256 MB and 1024 MB, depending on your system resources.
Threads: This determines how many CPU cores the engine will use for its calculations. A higher number of threads will increase the engine's strength and speed, but it will also consume more CPU power and may cause overheating or instability issues. The recommended value is equal to or less than the number of physical cores in your CPU.
Network File: This determines which neural network file the engine will use for its evaluation function. The default file is belkanet.nnue, which is optimized for classical chess. If you want to play modern chess variants such as Chess960 or King of the Hill, you can download alternative network files from the official website and select them here.
Syzygy Path: This determines where the engine will look for Syzygy tablebases, which are files that contain perfect endgame knowledge for positions with up to 7 pieces. Using Syzygy tablebases will improve the engine's accuracy and speed in endgames, but they also require a lot of disk space (about 350 GB for all 7-piece tablebases).
