Two great books from the Everyman Chess Library, Play the Grunfeld by Yelena Dembo and Play the Sicilian Kan by Johann Hellsten, brought together in one volume

The Grunfeld is an exciting and dynamic answer to 1 d4, and has become very popular at all levels of chess. A major reason for this is that it has been a long-time favourite of the World's strongest-ever chess player, Garry Kasparov. The Grunfeld very much relies on the principles of the hypermodern school of chess: Black allows White to erect an impressive-looking centre on the assumption that in the long run it could prove to be more of a liability than an asset. Play often becomes very complex and tactical, one of the reasons the Grunfeld appeals to ambitious players.

In Play the Grunfeld, however, opening expert Yelena Dembo circumvents this problem by producing a comprehensive and yet workable repertoire for Black, offering a solution against each of White's tries, whether it's a critical main line or a tricky sideline. After reading this book, you will have the required knowledge and confidence to begin playing the Grunfeld in your own games.

The Kan is an ideal choice as an opening weapon against 1 e4, as it
one of the easiest variations of the Sicilian to learn and play.The Kan is relatively
theory free in the traditional sense, and success is more likely to occur through
the understanding of development systems and a deep study of the
tactical and positional ideas for both sides.

In this book Johan Hellsten draws upon his vast experience in the Sicilian Kan, revealing his secrets and showing how Black can adopt this opening and play it with confidence. He provides the reader with a dependable repertoire, demonstrating what to do in the main lines as well as how to deal with White's tricky alternatives.
