That would be great if this would be possible.
I'm not a programmer so I wonder if such a tool already exist or if it can easily be created.
I have a repertoire that is rather wide with many alternative variations for my color of play.
I'm looking for some meaningful way to further narrow down the repertoire.
I have heard for example that the Kings Indian defense, used to be a popular opening, among top players in the past, but that it lost popularity in recent years, because it is actually not a very good opening.
I want to be able to visualise this for all openings.
