Description
AI Chess Master is a complete, browser-based chess game that lets you play against a smart computer opponent without installing anything or setting up a server. Built with pure HTML5, CSS3 and vanilla JavaScript, it runs directly in a modern browser on desktop, tablet and mobile, making it a practical choice for chess fans, learners and website owners who want an engaging game ready to publish.
Play Chess Against a Smart AI Opponent
Challenge the built-in AI at four levels, from Beginner to Expert. The engine uses the Minimax search method with alpha-beta pruning, so it plans ahead and plays with real strategy rather than moving at random. A live evaluation bar shows who is ahead in the current position, helping you learn from every move and spot turning points in the game.
Full Chess Rules, Presented Clearly
The game supports the rules players expect: castling on both sides, en passant captures and pawn promotion with an easy piece selector. Moves are recorded in standard algebraic notation, complete with check and checkmate markers, so you can review a finished game move by move.

Easy to Customize
Site owners can adjust the game through a single configuration file, js/config.js. Change the title and subtitle, board and piece colors, time controls, AI depth and thinking speed, animation speeds and ad unit IDs, without rewriting the game logic.
No Server, No Dependencies
Because the game uses only HTML, CSS and JavaScript, there are no frameworks, libraries or databases to maintain. Open index.html in a browser and play, or upload the files to any web host. That simplicity also makes the game fast to load and easy to embed in an existing site.
Optional AI Move Analysis
An optional enhancement can add AI-powered move analysis and hints using Anthropic Claude. This is not needed for normal play: the core game, AI opponent and all standard features work fully without it. The Claude feature needs a separate paid Anthropic subscription or credits, which are not included; without a valid API key it simply falls back to showing the position evaluation score.
