A properly structured Tampermonkey chess script requires specific metadata for compatibility, efficient DOM manipulation to avoid breaking the chess site's functionality, and safe handling of game data.
Some scripts help export moves directly to a local engine or tutorial engine for deeper study. Utility & Accessibility:
What are your thoughts on the ethics of userscripting in competitive browser games? Let's discuss in the comments.
After receiving the best move (e.g., e2e4 ), simulate clicking:
: Chess sites (like Chess.com) are Single Page Applications (SPAs). If you only run code once, it will disappear when the game refreshes. A MutationObserver detects changes in the page structure and re-applies the script.
Want a version tailored to a specific chess site (e.g., Lichess, Chess.com, ChessBase)? I can provide per-site selectors and a ready-to-use script.
open a live game page with such a script active unless you intend to cheat.
