SUMMARY

This chrome extension automatically highlights optimal chess moves in real-time during your chess.com matches, helping you to improve your game and make smarter decisions on the board. With this extension, you'll be able to take your chess skills to the next level and dominate your opponents. Try it out for free! Pin it to your tool bar to quickly toggle the engine, view the evaluation*, and see statistics on top opening book moves in real time. You can hit the 'e' key to conveniently toggle the engine and reveal the top move. Go to the options page to change the highlight color or search depth (right click the icon -> Option). The engine will continuously solve when it is your turn to move. It will quickly display a good move in ~1 second, but may change moves as the solve progresses and depth increases. If desired, the max search depth can be adjusted in the options. Normally, chrome will close extension pop-ups when you click away. If you want to keep it open all match so you can keep an eye on the information, there is a trick: right click in the popup and click 'inspect'. It will remain open. If you experience any buggy behavior, try refreshing the page! DISCLAIMER: Chess.com WILL ban your account if you use this tool excessively, and potentially your ip address after a second offense. They have sophisticated detection and know when you are making too many super human moves! I recommend using it sparingly in tough spots as a learning tool ;) KNOWN BUGS: - There are issues with pre-moving. If the move suggestion does not appear after a pre-move, re-toggle the switch to prompt the engine to re-solve. - You cannot have more than one chess.com tab open at a time. If it detects more than one chess board, it will fail to display the move properly. - You must not have the piece "Animation" setting set to "Arcade" - Occasionally, stockfish raises out of memory errors and the extension completely breaks, even if you refresh the page. Fully closing and re-opening the browser will be needed in this case unfortunately. I'm working on fixing this -- let me know if you can consistently reproduce this issue. If you have any questions, feature requests, or other bug reports feel free to email me. I am actively working to improve this extension. Hover over opening book moves to highlight them on the board. This extension currently uses stockfish 11, same as chess.com. I'm investigating stockfish 15 -- if you're interested in this, feel free to email me. *evaluation: https://support.chess.com/article/656-what-do-the-computer-evaluation-numbers-mean-like-225
