In this original book, Christoph Wisnewski, who is renowned for his innovative and adventurous opening ideas, provides the reader with an ambitious and all-encompassing repertoire for Black against every main line opening that White can play, based on the initial move 1...Nc6. The principal components of this black repertoire are the uncompromising Chigorin Defence, a long-time favourite of the brilliant Russian Grandmaster Alexander Morozevich, and the equally tricky Nimzowitsch Defence, advocated by Britain's first ever Grandmaster, Tony Miles.
