This book atracted me at first, since it looked good, and seemed to convey the essential knowledge any player who wants to improve his game needs. It dosent. after buying this books, i realise it was made for complete beginers, and was filled with extremly useless knowledge. The best example was a section about "mates in the opening", where Schiller presented how to mate in the scandinavian: 1.e4 d5 2.exd5 Qxd5 and if Ke2 then Qe4 mate. what does this useless examples, which will never occeur in a game (who plays 2.Ke2?) help me?Schiller is a 2200 player, who has published over 80 books, some of which he writes in days, and ive seen many of his books, all of low quality. I urge you not to buy this or any other Schiller book. No matter what your level is, this book just will not help you.
