Query: Is Nunn a real person or a computer?

This book is the worst of John Nunn. He can churn stuff out that is dry as sawdust. Perhaps the ultimate chess geeks can appreciate this. But I swear a computer could be writing this book. I have tried and tried again to read his books and they bore me into such a stupor that I contemplate giving up chess. On the other hand, this guy is a genius for getting GAMBIT up and running, and his Understanding Chess Move by Move is actually written by a human being! Having said all that, you should realize that I am not commenting at all on the substantive merits of this book--I am just saying, it is strictly technical stuff for hardcore chess geeks. There is NO personality here.
