Lucas Chess
Free open-source chess training program for Windows and Linux
Lucas Chess is a free, open-source chess training program for Windows, built by developer Lucas Monge (lukasmonk). It ships with 57 built-in engines ranging from beginner level to over 3600 Elo, making it one of the most feature-packed free chess programs available. The software supports the UCI protocol, so users can add even more engines.
The training system is where Lucas Chess really stands out. It includes modules for coordinate training, tactical puzzles, daily tests, best-move challenges, grandmaster-style play, opening preparation, and endgame practice. Players can track their Elo progress over time and compete in built-in Swiss tournaments and leagues.
Lucas Chess also functions as a solid chess database and game editor, with PGN import/export, opening book support, and engine-vs-engine tournament tools. It supports over 26 languages and is licensed under GPL-3.0, with the full source code available on GitHub.
