A new and fantastic effort by Russian journalist and historian Sergey Voronkov.
Really a unique document containing a selection of annotated games, the historical context, pictures, cartoons, tables and much more about all Soviet Championships between 1920 and 1933. Voronkov covers each tournament seperately and in detail.
Meet Botvinnik in his younger years, his rivalry with Nikolai Ruimin, Levenfish, Alekhine(!) and many other early-Soviet giants.
