User reviews

Users praise Chessconnect for seamless and reliable integration with multiple electronic chess boards on popular platforms like chess.com and lichess.org. The extension enhances gameplay by enabling bot matches and smooth local vs online interactions. The developer's active support and frequent updates contribute to user satisfaction. However, some users report issues such as connectivity problems with certain boards after updates, limited support for lichess analysis mode, bugs in chess.com analysis mode related to board orientation, and UI confusion. Overall, it is a highly recommended, free extension that significantly improves the online chess experience with physical boards.

  • Supports popular chess websites such as chess.com and lichess.org effectively.
  • Allows playing against bots and local vs online player matches, enhancing gameplay experience.

  • Limited or no support for analysis mode and studies on lichess.org, which users desire.
  • Bug in chess.com analysis mode where moves only register if the physical board is oriented correctly for the side moving.
  • Some confusion in the interface, such as difficulty locating the "connect" button on chess.com.
  • Lack of piece sliding animation, requested for better visual experience.

Werkt beter dan verwacht. En het is ook aangenamer om een chromebook langs je schaakbord te hebben dan een smartphone.

Finally I can play on Lichess.org seamlessy with my Certabo board avoiding the headache of the original software. Excellent work Chessconnect!

Excellent extension, great work! It integrates seamlessly with my Chessnut board. Initial feedback: - It would be amazing to support the analysis board / studies on lichess. Jörn mentioned this can be considered if there's enough interest for it. Lichess analysis / studies are (in my humble opinion) the most powerful / user friedly game analysis tool. Also, following live game (as a spectator, not player) would be nice. - I don't know if this is supposed to work or not, but when I watch broadcast games on chess.com the board is activated and highlights the black moves (presumably seen as the opponent) but does nothing for white (presumably seen as the player). Then if I try to make the moves myself they appear as differences. It's as if the white pieces are frozen to the initial position. This would be a nice to have, but it's not as important as analysis mode on lichess.
