The book by sports journalist O. Skuratov is structured in the form of a lively, confidential conversation with the reader. Sharing his more than thirty years of experience in playing preference, the author offers a coherent system of improvement based on both mathematical calculations and the general laws of card games. He talks about the components of success - intuition, accurate play, endurance, and the ability to fight in difficult and uncertain situations. The book is intended for a wide range of preference lovers who, in addition to the “science of winning,” will find in it a number of interesting historical excursions and psychological sketches.
