The world's first textbook of chess strategy and tactics, entirely based on games with computers! The basis of this “textbook of the 21st century” is made up of 75 deeply commented games played by the hero of the book with the strongest computers in 1990-1997. But “the great David” had to fight not only electronic “goliaths” in his life. This dramatic confrontation between a creative personality and the system is also described for the first time. So, under one cover there are hidden, as it were, two books: an unusual chess textbook and a book of memoirs of an outstanding grandmaster.
