Collecting incriminating evidence and custom-made inspections of government agencies, purchased courts and bailiffs, custom-made bankruptcies and hostile takeovers, black PR and legislative lobbying - for the first time in one book, the mechanisms of competition that have been tested in practice, but are not among the traditional ones, are analyzed. Such actions , aimed at both protecting and fighting competitors, are a certain know-how of individual Russian companies that have gained this unique experience in their own practice. The book provides answers to a number of pressing and sensitive questions, including how and where a competitor can strike, how to repel such attacks, and how to intensify one’s own military operations. The technologies described in the book will be of interest not only to managers of small and medium-sized companies, but also to business “sharks”, because gaining or maintaining market share is one of the most pressing problems of today's business.
