All the lines presented in this book are very old, some even dating back to medieval
times! Lots of things were known about these systems before chess engines started
to become very strong, but now we have completely new ideas from not only a
tactical, but also positional, point of view on positions that have simply resurfaced
in recent times. The rebirth of these lines has become so popular that during my
work on this book I was amazed to see such a level of popularity.
To make this book readable we broke some positions into smaller files wherever we
could. In all our opening books we tried to present at least the basics of many openings and lines:
the problem is that basic knowledge about openings is growing even bigger, and it
is not an easy job to comprehend and assimilate all that material. Thats why we have
also tried in this book to be as concise as possible. After all, reading a book should
not only be an aesthetic/interesting endeavor, but also a practical/useful thing at
the same time.
