The worst thing about this book is its title, which gives the impression it is for beginners and an experienced player can learn nothing from it. On the contrary, I had been playing for about 15 years when I read it and it gave a big and permanent boost to my game. It explained and clearly made sense of various strategic concepts that I'd seen in different books but hadn't understood as a coherent whole. The chapter titles say it all; outposts (strong squares), weak pawns, open files, half-open files and minority attacks, dark and light squares, and space. Numerous well-annotated games demonstrate how the ideas work in practice. The book majors more on structural aspects and chess as a science than on dynamic aspects and chess as an art or a fight, somewhat reflecting its author's playing style; but there are plenty of books on these other aspects. Short and to the point, it makes difficult concepts seem simple. Full marks to the publishers for reissuing it; opening theory may come and go, but this never goes out of date.
