A cm-chessboard extension which knows the rules of chess to validate moves, support promotions and does some fancy square marking.
Work in progress, all features are implemented for now. It's also in use in production at https://www.chessmail.eu and https://www.chessmail.de
- do move validation ✅
- keep track of the moves history ✅
- set markers for last move, check, invalid move, legal moves etc. ✅
- display a promotion dialog, if needed ✅
- add sounds ✅
- allow premoves ✅
This will replace many parts of my https://github.com/shaack/chess-console project and make it easier to use.
