The third volume of Elk and Ruby's treatise on Viktor Korchnoi, penned by FM Hans Renette and IM Tibor Karolyi, covers the period 1981-1991. This encompasses Korchnoi's famous world championship match with Karpov at Merano in 1981, his candidates matches against Portisch and Kasparov in 1983, Hjartarson in 1988 and Sax and Timman in 1991, as well as the candidates tournament of 1985 at Montpellier, the GMA world cup series and major tournament performances. Much biographical colour is supplied on his life and character, with this period including his family's arrival from the Soviet Union to the West in 1982 and its subsequent breakup. Like in volumes I and II, original material is provided from interviews with key protagonists and sources from a wide range of languages are used.

140 games and fragments are analysed in detail in this work. Other opponents include Tal, Spassky, Ivanchuk, Topalov, Gulko, Larsen, Sosonko, Seirawan, Ribli, Torre, Yusupov, Van der Wiel, Van der Sterren, Andersson, Polugaevsky, Nunn, Miles, Short, Speelman, and Beliavsky, among others.

The book is supplemented with a generous supply of photos, some taken from the Korchnoi family archive and never before published.
