"... The Sicilian Sveshnikov Move by Move has a lot going for it. Those who want not just analysis but also prose to explain the ideas behind this aggressive line of the Sicilian will find Lakdawala's work quite helpful and this includes those rated up to 2300. ..." - IM John Donaldson (2017)

I bought Lakdawalas Opening Repertoire 1. e4. However, I don't understand the first chapter, which is about the Bishop Opening: 1. e4 e5 2. Bc4
Firstly, he gives four games with 2...Nf6 3. Nc3.
Secondly, he discusses five games with 2...Nf6 3. d3
He does not recommend either 3. d3 or 3. Nc3, although these are two rather different opening systems.
Does anyone has this book too and can you explain me his reasoning? Thanks.

His reasoning is that you must decide.
Thanks. That must be it. It is a rather strange repertoire book, but still I like it. The book does not provide strict paths you have to follow, but some ideas of how you could play instead. For me this book is good for inspiration. If I need more detail in some variation, I have to investigate this myself by playing or database research.

Thanks for your detailed feedback. I appreciate that, because it made me think about why a still like this book (1. e4 opening repertoire by Lakdawala). But I have to disagree with your conclusions.
First of all: this is not a bad book. Whether it is a good book or not, might be a matter of taste. For me it perfectly suits my playing style (positional) and strength (Elo 2000-2100).
Lakdawala is always honest in his preference of one line over another. About his Scandinavian book, for example (which I have sampled and liked), he DOES examine the Qa5 line. The one he does not examine is the Qd8 line, which is the least played (although gaining in popularity). The blank is filled by the Kotronias book, which covers ONLY that line! (also stated on the cover...) His book on the Alehkine defence is also very good and explains in detail his preference of one line over another (convincingly too!) I definitely prefer books with prose, explaining key ideas, rather that endless lines of variations. I also appreciate a writer with a lively writting style, as opposed to a dry "objective" one. Lakdawala is NOT a new Schiller. His style and content is always interesting and informed. That being said, even Schiller has written good books (as others have pointed out). His "Winning with the hypermodern" (with Raymond Keane) is still one of my favourites!

Cyrus is both a stronger player and better analyst than Schiller was. He’s currently working on a book devoted to compositions. I think he’s also working on a book about Carlsen’s losses.

I'm not sure. I do think Karolyi's books will probably have a longer shelf life than many of Cyrus' opening books. But Karolyi's analysis is often very long computer lines that take quite a bit of work to unravel. I think Cyrus knows his audience better.
Caveat emptor: I'm FB friends with both authors.
PS I personally enjoy Lakdawala's anecdotes.
Me too, but some people would think that he is just filling space.
They could be good enough for another book.
Like his fight with Gufeld.
He is filling space.
His most recent books have at least two anecdotes per page (and not anectodes also)...
His newest books are 400+ pages, most of that is anecdotes. He is also sometimes inappropriate for a younger audience.
