Pictures

The logo, the icons and the picture on the home page (a lighthouse shaped like a chess rook above a sea of chess squares) were generated with artificial intelligence. They are artistic depictions.

Chess pieces

The pieces on the chessboards are the “cburnett” set by Colin M. L. Burnett, as also used on lichess. They are licensed under the GNU General Public License, version 2 or later, and are used unchanged.

Texts of the plans

The texts on the plans and pawn structures were written with the help of artificial intelligence. They may contain mistakes.
