Of course, we've already had a rather lengthy discussion of what should be included and what shouldn't, but now that the book is out, it's worth revisiting. To get the ball rolling on some of the points in Christoph's list:

Hansen questions the inclusion of the Gothenburg Variation. I admit that the idea is not great per se, but the story behind its creation was simply too good to pass over (the chapter heading and the first paragraph could have rung a bell as well). Besides, the Gothenburg is actually a quite good example of an unsuccessful attempt of an opening idea (antithesis).
I agree. I thought this was worth including.
Quote:Hansen wonders why the "Anti-Zaitsev" novelty from Anand - Adams made the book, but not the Zaitsev itself (as he suggested). I explicitly stated it as a representative example which shows how the halflife of an opening idea has shrunk in comparison to earlier times. On the other hand, Hansen fails to mention why the Zaitsev (or the Open Ruy) qualifies (in his opinion) and why the Berlin does not.
I think you have to include the Berlin, but I might have moved it back in time to the year 2000. For me, 3..Nf6 is an obvious move, so not in itself a great idea. But the idea to play it in a world championship match against the greatest attacker of our time: that was special.
I would have included the Breyer. The idea of undeveloping the knight so that it could rest comfortably on d7 instead of being hung out on the edge was a pretty good one. And it was was one of the main ways of meeting the Ruy, if not the main way, for a number of years.
I would not have included the Open. It's an important system, to be sure, but the idea of taking a center pawn doesn't strike me as one of the Greatest Ever. It strikes me as pretty obvious.
I wouldn't have included either the Zaitsev or the novelty. I don't find either all that significant, but hey, that's me.
Quote: To answer Hansen's question about the inclusion of Lasker's Defence to the Queen's Gambit, the reason is purely historical (Lasker's Defence was [besides Tarrasch's Defence] the most traditional way of meeting the Queen's Gambit in the first part of the 20th century).
I agree that Lasker's was worthy of inclusion. It's the first chapter in Sadler's QGD book and fundamental to the whole opening.
But I would also have included the more basic idea of playing the QB to g5, rather than to b2. If nothing else, it would have been a good excuse to include Pillsbury-Tarrasch, Hastings 1895.
