tarrasch was a highly esteemed chess writer. his "dreihundert schachpartien" (1895; 300 chess games) was a landmark; it was the first 'best game collection' with in-depth annotations. the notes were readable and could be understood by ordinary players. this led to his being described as the "praeceptor mundi", which is latin for 'teacher of the world'. the book was called by the american grandmaster reuben fine "one of the monuments of our game".f/w
