The problem with making a criticism of your post is that you go away and don't come back, but ..... The questions (unanswered) are: 1. does Mchess contain lines specifically put in the book to 'deal with' other specific opponents ? 2. if so, are these lines deliberately inserted, or have they just come about as a sideline of 'improving' the book ? 3. if so, do these lines have a material effect on the SSDF rating of Mchess ? Other questions are: 1. do you consider books in general to be just neutral data, or is there some moral issue to consider ? 2. do you have any comments on the issue of some kind of agreed basis for what should and what should not be acceptable in book construction (ie ECO only, or extra lines, or cptr-cptr game lines, or anything goes, etc. etc.) Chris Whittington
