cli-chess is a terminal-based chess application that supports playing online via Lichess.org and offline against the Fairy-Stockfish engine. It features a modular MVP (Model-View-Presenter) architecture with clear separation of concerns across core game logic, reusable UI components (board, move list, chat, clock), menu systems, and API integration. The application supports all Lichess chess variants, includes features like premoves, takebacks, draw offers, chat, blindfold mode, unicode pieces, custom theming, and PGN export. Entry point is src/cli_chess/__main__.py, with gameplay driven by user input flowing through presenters to models, which update views via an event system. External dependencies include python-chess for board logic, berserk for Lichess API, and prompt-toolkit for the terminal UI.
