  <p>Having said all that, this week we are releasing a new book by a renowned French chess coach that has relatively little theory and guides you to sound openings where your opponent can quickly get in trouble. So stay tuned and look out for it!</p>

Answers.Body: <p>A chess engine with a good opening book might be a better source to identify sidelines or novelties.  For example, with Rybka you can view the opening book with it's list of moves while putting the engine on infinite analysis and see what moves it is looking at that aren't in the book list.
  You can even do "deep position analysis" which I think generates a pgn with a huge width of moves -- you could then trim out the book lines.</p>

Comments.Text: But there are at least three main line continuations for white here (Nc3, Nf3, g3), with multiple replies to each like ...c5, ...d5, ...Bb4, ...b6, depending. 3.a3 only prevents one, I'd say it's a bad move. So you're basically asking for a list of early deviaitions from theory that might be playable? That's a very broad question.
