In 2007 I presented my fourth book on tennis - the others were published in 2001, 2002 and 2004. After publishing the last I felt empty. Eight years have passed before now presenting the fifth. Over these years I experienced a wide range of situations, both in tennis and out of it, in several domais and from diferent perspectives. The book does not aim to be more than it appears to be: a flip book with simple and concise presentation of facts I consider important in the world of tennis, at both the highest level and in the amateur sphere. The reader has the chance to have "two books in one". Firstly, the tennis strokes considered classic; and secondly, modern strokes. Controversy aside, the evolution of tennis strokes depends greatly on the material and the practice component.
