About Chess.com Highlighter

This extension is designed to provide an enhanced learning experience for beginner and intermediate chess players on chess.com. Acting as "training wheels" for people new to the game, it offers visual aid that help players improve their understanding of chess fundamentals. Features: 🔹 Highlight Hanging & Attacked Pieces Automatically identify which squares are hanging and under attack by you and your opponent. 🔹 Highlight Movements (Safe, Attacked, Hanging) See which squares are safe, attacked, or will leave your piece hanging before you make your move. Additionally, squares that result in stalemate or checkmate are highlighted. 🔹 Highlight All Attacking & Defending Pieces Select (right-click) any square on the board to highlight its attackers and defenders. Note: Do not use Piece Animations: 'Natural' and 'Arcade'. For some features to work, the 'Highlight Moves' and 'Show Legal Moves' settings need to be turned on. Includes a 3-day free trial. If you encounter any issues or have suggestions for new features, please contact me at chesshighlighter@gmail.com
