Frequently Asked Questions
How do I play Chess?
The game uses the chess.js library for full FIDE rule enforcement including castling, en passant, pawn promotion, check, checkmate, stalemate, and draw detection. The board is rendered as an 8x8 grid of clickable divs with inline SVG piece graphics. Legal moves are computed per-square and highlighted as green dots or red backgrounds for captures. Move history is displayed in standard algebraic notation with FEN-based undo.
What difficulty levels are available?
Multiple levels from beginner to advanced. Lower levels make occasional random moves while higher levels use deeper search and better evaluation. Choose a level that matches your skill for a competitive game.
Does it support all chess rules?
Yes. Full FIDE rules including castling (kingside and queenside), en passant capture, pawn promotion, check, checkmate, stalemate, and draw conditions. All legal moves are validated.
Can I take back a move?
The game enforces moves once made against the AI. Start a new game to try a different strategy from the beginning.
