My passion for chess urged me to share this game even for the modern Opera browser. Chess is a sophisticated and elegant game and using the effective chess.js and chessboard.js* libraries, I have also included in the extension useful advanced options, such as saving the notation in PGN and FEN format.
- Chess game with show notations
- Flip Chessboard
- Legal moves highlight
- Status notification in header
- Save notations in PGN or FEN format
- Set Chess Engine and template style
* Add-on is based on WebGL chessboard library (https://github.com/jtiscione/chessboard3js)
