Body: <p>Not so long ago I was looking for a <a href="https://chess.stackexchange.com/q/6519/703">comprehensive list of openings</a> (and received an excellent answer with a huge list). Hearing a lot about unsound openings, I am curious whether I can have a comprehensive list (I have read <a href="https://chess.stackexchange.com/q/6451/703">this answer</a>, but it is just a few gambits) of unsound openings.</p>

Comments.Text: A list of sound openings would include numerous variations per opening. The list could be tremendously large. Further, the definition of a sound opening can be subjective. Sound for whom? GMs? B-players? If we knew why you wanted this, perhaps we could give more concise answers.

Comments.Text: Even Barnes Opening 1.f3 is probably "sound" because it's likely still a draw with best play.

Comments.Text: @TonyEnnis I know that it can be large (a really big list of openings, I have is 10.000 openings with various variations). I mean sound by the definition of GMs. As for why I need this is for a datamining competition. I wanted to have it as a list of the features.

Comments.Text: So what you need is an opening 'book' that includes the informant-like 'white is better' sort of glyphs.  Then you could write some code traverse the list and fetch good openings, bad openings, or whatever openings you wish.
