Recently, I’ve been looking at some of my old middlegame books, both as potential teaching material and for the pleasure of reminding myself what the bods had to say. A few of the found jewels: Max Euwe and Hans Kramer’s two-volume work on the middlegame; three volumes of “Complete Chess Strategy” by Ludek Pachman; “A Contemporary Approach to the Middlegame” by Alexei Suetin; and three different editions of Aron Nimzowitch’s “My System” (one in Russian).
