Georgy Lisitsin (1909-72) was a respected Soviet master, theoretician and writer. In 1958 he published a revised edition of his most ambitious work, entitled Strategy and Tactics of Chess, which became one of the most legendary manuals in the Soviet chess school, and no doubt one of the books that motivated the young Bobby Fischer to learn Russian. Lisitsin broke down Strategy and Tactics into their constituent elements, enabling players of all levels to study chess systematically, learning from carefully selected game fragments and studies. Key Elements of Chess Strategy and its companion volume Key Elements of Chess Tactics are the first ever complete English translations of Lisitsin's classic. In Key Elements of Chess Strategy , Lisitsin breaks down the Foundations of Strategy into categories such as piece placement, exchanges, weaknesses and prophylaxis, followed by a section on Devising a Strategic Plan, including concepts such as blockading, undermining, the initiative, pawn chains, and planning in the opening.
