I saw, some weeks ago, a video of the great GM Roman Dzindzichashvili, claiming that Sicilian Dragon is somewhat refuted, or at least it is a dubious system. I normally play the Grand Prix against the Sicilian, but if what I saw on the video is true, I may switch to the Yugoslav attack.
Basically my question is the dragon really a bad opening and is the Yugoslav attack the its "refutation" (strong word I know) ?
