Chess Strategy is a book by International Master Edward Lasker about the theory and strategy of chess, presenting the leading chess principles. After thorough and detailed discussion on fundamentals Lasker treats Openings in which, he considers, the leading principles are of more deciding influence than in any other stage of the game. Next he lays the principles governing the End-Game which are generally applicable, since the middle game is influenced by end-game considerations. The second part of the book treats the Middle Game. The author shows how the various plans initiated by the various openings should be developed further. To certify a systematic understanding of the middle game, a large number of games taken from master play, is given with many detailed notes.
