Suppose I only want to buy a single book for my opening repertoire as White and Black. Which book would you suggest?

 

I want something practical and I am not hoping for any magic. Just a good guide into a playable middlegame.

I know only one : The chess advantage in Black and White by L.Kaufmann 2004

it's however a thick book. Maybe Davies'dvd "opening for busy people" (or something close) would be more appropriate ?

Interesting! It was when reading about Kaufmann's book I got curious about other single volume repertoire books. I read a quote along the line that there exist other single volume repertoire books for those who seek a playable middlegame but that the Kaufmann book might aim for more.

Hoping to see many post on this subject.

i am cheapskate so i only spend money on the best of the best books.
