I think the books approach is a little too aggressive. I don't think we should go so far to label people 'the enemies of the free world!' No need to read it. I think the title speaks for the banter. I respect Kasparov as a chess player. I own all the predecessor books and really enjoy them. They are great additions to chess and I'm thankful to own them. Might not greed and enmity be the product of this predisposition for politics.
