Chess. Theory of sacrifice

Chess is said to be 90% tactics - this has always been the case, but with the development of chess programs, it has become clear that tactics play an even greater role in this game. Good tactical vision and the ability to combine moves distinguished all outstanding chess players, and these qualities should be developed and improved by everyone. This book is the foundation for developing tactical skills. Rudolf Spielmann managed to systematize and classify combinations, tactical strikes, and sacrifices. His work is so good that practically nothing new has been said after him. To learn how to combine in chess, you need puzzle books that you should work with daily. But you should start with Spielmann's book. The new edition has undergone thorough computer editing, and necessary corrections and clarifications have been made to the book.
