About this extension

A Chrome chess extension

Read the publisher’s full description

Suggesting the best move (on Lichess) and automatically moving the pieces How to run the extension: - Open the Extensions by clicking on the puzzle icon next to your profile avatar - Click on the pushpin icon next to ChessPro to pin the extension, a knight icon will show up on the taskbar - Click on the knight icon - Turn on the extension Features: - Customize analysis depth: Higher depths take longer to analyze but will result in better moves. We recommend using depth 9 or above. Note: Using depth too high risks your account getting closed. - Max wait time: Only applies to “Automove” mode. This allows you to set how long it takes for the extension to make the next move. - Winning chance: Get realtime evaluation of the match. Note: this is based on the assumption that the opponent makes perfect moves, so it's fine even if the evaluation fluctuates. - Automove: The extension automatically plays for you. - Voice suggestion: The extension will tell you which move to play using voice suggestion (Recommended on Lichess). - Auto play new game: The extension will automatically find a new game once the current one finishes. - Bongcloud: Joke opening. Notes: 1. The extension doesn’t highlight the positions when playing on lichess.org, is this an error? No, this is intentional. lichess.org can detect cheating if the extension draws on the screen, so we disabled this feature entirely. However, you can use the extension by turning on either the autoplay mode or voice suggestion mode. 2. If you have any suggestions or found any issues, please email us at speedrunlegend123@gmail.com.
