You are all geared up as Black to play a sharp main-line opening – but then White opens with some unusual first move. Every chess player knows how disconcerting this can be, and how easy it is for Black to land in trouble if he reacts incautiously.

This book is the first time that a master has provided sound practical advice on how to handle both the white and the black side of these openings. Dunnington’s commonsense approach to such openings as the Bird, Nimzo-Larsen, Sokolsky and Grob is based on his many years of experience of club, weekend and international chess.

International Master Angus Dunnington is one of England’s most productive authors, with a string of well-researched, user-friendly books to his credit. He has written a regular column in the Yorkshire Post for more than 15 years.
