Best books on middlegame strategy? What are the best works trying to systematically summarize all middlegame themes and strategies: e.g. space advantage, pawn structures, exposed king, minority attack, isolated pawn, hanging pawns, etc. etc. I know of Euwe and Kramer two volumes work about the middlegame, but are there others, too? (PS no, I am not talking about Bronstein's Zurich 1953. Although it's a great book, I am speaking of a different kind of work.)
The two books by John Watson about strategy. These themes are considered from a historical viewpoint usually in contrast to the way they are presented in textbooks. Even if you find a favorite textbook then later you should verify everything against John Watson's books because he always gives counterarguments and counterexamples to what is established as the usual course material.
