No, you can't play chess games on CRC.
CRC is NOT meant to play games like chess.com or lichess.
The two main purposes of CRC are to allow you to build your chess repertoire and to help you memorize it.
No, we believe that the process of creating your repertoire is an important part of memorizing it.
However, in the future we may implement a repertoire sharing feature…
No, it doesn't, because we think that there are already enough powerful and free tools like lichess.org, which help you do this.
Any help on the project is useful and appreciated, please join our discord server to meet the community and propose your contribution.
