Nibbler  is  a real-time analysis GUI for Leela Chess Zero (Lc0), which runs Leela in the background and constantly displays opinions about the current position. You can also compel the engine to evaluate one or more specific moves. Nibbler is loosely inspired by Lizzie and Sabaki. These days, Nibbler more-or-less works with traditional engines like Stockfish, too. Nibbler is loosely inspired by Lizzie. By far the best ICCF analysis tool for Leela. v.2.3.9: Reorganisation of the app's internal files to facilitate a new Linux build script. Dev menu item to do a live reload of the engines.json config file. (Requested by a certain Lc0 dev.) Nibbler 2.3.9 download from page Our social media:
