Hallo Jan und ebenfalls ein frohes neues Jahr,
zu den Fragen ...
1. User-Manual:

2. die LiChess Problematik kann ich nicht bestätigen. Hast Du die von Chessnut empfohlenen Einstellungen in LiChess und ChessDotCom übernommen (s. A.)?
Von Chessnut gab es dazu nämlich folgenden Hinweis:
"Lately, we've received feedback from some users indicating that Chessnut Vision isn't functioning properly, even when using the platform's
default skin. This is due to changes in how Chess.com and Lichess handle chess piece movement. If you encounter issues while using Evo on these platforms (typically characterized by pieces being dragged but not successfully moved), please check the following settings:
For Chess.com: Click on the gear icon in the top right corner (Settings) - Board and Pieces - Move Method - Set to Drag or Click.
For Lichess: Click on your username in the top right corner - Preferences - Game behavior - How do you move pieces? - Choose "Either."
Viele Grüße Bernd
