It is rare that a Correspondence World Champion annotates a collection of the finest games from his career with detailed notes that penetrate deeply into the analytical and decision-making process. Yet this is precisely what Grigory Sanakoev has done, and the result is a work packed with entertainment and instructive value, ideal for study by ambitious players. Sanakoev's style of play, though as well-rounded as one would expect from a World Champion, tends toward the brilliant, with sacrificial attacks featuring in many of his games. As these attacks have had to stand up to the most scrupulous analysis, the reader will develop a feel for when an attack is sound, and when it is too speculative. Besides the analytical feast he presents, Sanakoev packs a great deal of general chess wisdom into these pages, often featuring pertinent quotes from the greats of chess.
