It handles move generation and validation, board representation in multiple formats (FEN, EPD, Shredder FEN), and detection of game-ending conditions (checkmate, stalemate, draws). It reads and writes PGN files with comments and variations, probes Polyglot opening books and Syzygy/Gaviota endgame tablebases, and communicates with UCI and XBoard chess engines via asyncio.\n\nThe library has no runtime dependencies and includes full type hints. It supports standard chess and variants (Chess960, Atomic, Crazyhouse, and others), integrates with IPython/Jupyter for board visualization, and is actively maintained across modern Python versions. High install friction stems from source-only distribution, though the codebase is stable and production-ready.","worth_installing":"Yes, for chess applications and analysis tools. The library is stable, actively maintained, and provides a comprehensive pure-Python API with no external runtime dependencies. The GPL-3.0+ copyleft license is appropriate for open-source projects but requires review for proprietary use. High install friction (source distribution) is a minor friction point but not a blocker for most workflows."},"id":"chess","links":{"html":"https://skillfed.io/packages/chess","md":"https://skillfed.io/packages/chess.md","pypi":"https://pypi.org/project/chess/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-02-25","license_spdx":null,"license_treatment":"copyleft","name":"chess","python_support":"supports_current","summary":"A chess library with move generation and validation, Polyglot opening book probing, PGN reading and writing, Gaviota tablebase probing, Syzygy tablebase probing, and XBoard/UCI engine communication."},"popularity":{"monthly_downloads":3739913,"position":2510,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.11.2"}
