content: When you first see this book you figure, well the content has to be better than the cover. As amazing as it might sound, the content is even worse. The amount of errors really baffled me and stressed me out. Trying to look up things and the entire layout is just awful. How awful books like this get published is beyond my knowledge. Perhaps someone lost a bet or Schiller owns their soul. Maybe if your a 900 player this would help you break 1000. If your getting this book thinking your gonna be able to defend d4. I guess your gonna have to find out the hard way how shoddy this book is. A bad chess player that writes awful books is a scary thing. I think Ken Smith and Schiller should start their own club. Donate your money to a good charity or buy yourself something worth having. The only use this book has is the hope of being burned when no logs are left.
