Query: The best book on strategy

The Art Of War is the best book of war strategy I have ever found. Each of the 13 Chapters describe one aspect of war strategy in a clear way. Even if this book as 2400 years, it is still even more relevant today as strategy it is applied to other sectors like business and sport (Sun Tzu For Success: How to Use the Art of War to Master Challenges and Accomplish the Important Goals in Your Life).This very is a clear translation without any commentary. While commentaries help to explain the views of Sun Tzu, I prefer this version because it is so clear and easy to read.
