Book excerpt: In this enlarged edition of a modern classic (first published in 1991) on the battle of chess ideas, grandmaster Mihai Suba developed the concept of ?dynamic potential? in modern chess strategy. In improving your position on the board the old strategy principles often lead to conflicting conclusions. Suba takes another view on the meaning of, for example, ?bad positions? and ?quiet moves?, and uses a light touch to explain his ideas. With many entertaining and instructive examples the author explores ?the accumulation of potential? as the modern way to get the advantage. A thought-provoking and yet very practical guide.
