Author covers ALL chess openings by lightly analyzing games grouped by major system.  His goal is to briefly show best play of each opening.   A unique approach, he divides the book by White systems and Black defenses.   This is the 2ND EDITION, where he has chosen 1 e4 as the best start (as opposed to 1 d4 in the 1st edition).  Furthermore, in this 2nd edition, he no longer printed the Black section upside-down from the White (but still keeps the division).   He has updated lines from the 1st edition as well.  

 Figurine algebraic notation.    Separate White/Black index of variations.  Index of names.  Bibliography.  467 pages
