## Description

Chess PGN Master is a comprehensive Chrome extension designed for chess enthusiasts ranging from amateurs to professionals. It facilitates efficient learning by allowing users to review, study, and analyze chess games from PGN files. Supported by a powerful chess engine (Stockfish 13), users can perform game analysis, blunder checks, and play out positions against the engine to deepen their understanding.

Beyond basic viewing, Chess PGN Master offers advanced features like easy navigation, support for electronic chess boards connected via Bluetooth (including brands like Millennium, Certabo, DGT, and more), and the ability to color squares and draw arrows to annotate games visually. It supports Chess960 variants, cloud storage integration (Google Drive, Nextcloud, Seafile), and includes curated annotated games from world champion José Raúl Capablanca. The trial restricts viewing to the first 20 games, while the pro key unlocks saving and full access, making it an ideal study and training companion for enhancing chess skills.
