Opening Repertoire Practice feature

Hi,

I am huge admirer of chess.com which provides excellent platform to chess lovers across the world.

It would be great value addition if chess.com can provide members way to practice-test their opening repertoire knowledge. E.g. If some member wants to practice French from white side, you can put initial position (1.e4 e6). Member will make white moves. If member finds good move, you can proceed with good black replies. If he fails to find good move, ask to retry (can provide hint if needed). At the end of opening phase, score his performance based on good moves found in first attempt. Also can highlight the bad moves and the good alternative moves.

It will immensely help members to practice and improve their opening repertoire.

I think chess.com already has opening database (explorer). If you can create UI on it, it will provide great value to the members.

You can also vary number of openings that can be practiced per day/week/month based on type of membership. 

Thanks and Regards,
