Chess pieces
Board diagrams use the Merida piece set by Armando Hernandez Marroquin, licensed under the GNU GPL v2 or later. The diagrams themselves are built in HTML and CSS.
Tools used to check chess lines
Chess lines on this site were checked for legality with chess.js (BSD license) and evaluated with Stockfish, which is free software under the GNU GPL v3; its source code is at github.com/official-stockfish/Stockfish. Neither runs on this website; they were used by the editors.
Videos
Embedded videos belong to their channels: ChessHelper AI, Chess.com, Lichess, DecodeChess and Aimchess.com. Each is credited and linked under the video on the page where it appears.
Icons and typefaces
The site icon is built from the Merida white queen. Text uses the fonts already installed on your device; no web fonts are loaded.
