The Najdorf Sicilian is one of the key battlegrounds of modern chess. This opening line occurs in a high proportion of top-level games, and is popular amongst players of all levels. The English Attack (Be3 and f3) became popular as a direct attacking method against the Najdorf in the 1980s, following its successful use by Nunn, Short and Chandler. Since then, it has become established as the most critical line of the Najdorf, with Anand and even Kasparov himself using it to devastating effect at the highest level. This book is the first to be devoted to this most topical of openings, and its comprehensive coverage will enable players of all standards to play either side of the English Attack with confidence.
