It would be great to be able to see in our profiles the success rate per opening [and even per variant] depending on who's initiating it.
- against Sicilian defense: 33% (win:1 / games:3)
- playing Sicilian defense: 50% (win:2 / games:4)
This shouldn't be too difficult to add as the opening variant is already stored per game played.
I don't think this feature should be made public though, it's just a personal thing to know what openings to revise and perfect!
What do you think?
