Open Source C++ Chess Games for Linux

Stockfish is a free, powerful UCI chess engine derived from Glaurung 2.1. Stockfish is not a complete chess program and requires a UCI-compatible graphical user interface (GUI) (e.g. XBoard with PolyGlot, Scid, Cute Chess, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) in order to be used comfortably. Read the documentation for your GUI of choice for information about how to use Stockfish with it. Stockfish is a 11-time winner of the Top Chess Engine Championship. Stockfish is open source (GPLv3 license). That means you can read the code, modify it, and contribute back. You can use Stockfish on your computer or on your iOS or Android device. So you can get world-class chess analysis, wherever you are. The Stockfish engine features two evaluation functions for chess, the classical evaluation based on handcrafted terms, and the NNUE evaluation based on efficiently updatable neural networks.

Eagle Mode is a zoomable user interface (ZUI) with file manager, file viewers, games, and more. This project is about a futuristic style of human-computer interaction, where the user can visit almost everything simply by zooming in. It features a portable C++ toolkit API for developing such ZUIs, and it features the Eagle Mode application, which provides a virtual cosmos with plugin applications. The most important one is the professional file manager with its rich, scriptable command set. It integrates file viewers for most of the common file types, as well as an audio and video player. Furthermore, the virtual cosmos contains a chess game, a netwalk game, a 3D minesweeper game, a multi-function clock, a stock watchlist, some fractals, and a Linux kernel configurator in form of a kernel patch.
