From the cover: Grandmaster Davorin Kuljasevic teaches how a modern club player should evaluate positions: by looking beyond the material balance. With many instructive examples he shows how the actual value of your pieces fluctuates during the game, depending on many non-material factors. When sacrificing material, modern club players need to be able to suppress their need for immediate gratification. You need to be ready to live with uncertain compensation when giving up material. With the help of many fascinating examples, Kuljasevic teaches you the essential skill of taking calculated risks. Further information about the book is available at newinchess.com. 2 pictures.
