Chess is basically a struggle of surprising dynamism, in which two opponents always try to break the balance of power existing at the beginning of the game, This struggle, - in which the mind is constantly straining, always looking for the right solution, fighting the opponent's ideas, always appealing to the knowledge acquired through study, to ingenuity, imagination, reasoning - that is, in fact, all the beauty of chess and at the same time its indisputable value.
As in every fight, in chess a man invokes everything that can give him superiority over his opponent, over everything that can be a means of winning.
Chess theory is a methodological study of all these means of struggle. Any chess player who wants and progresses cannot do without studying theory. At the current stage of chess development it can even be said that without study no player - with extremely rare exceptions - can surpass the strength of the second category. This explains why almost all players seek and study theory, but it must be done methodically, starting from simple to complex, from solidly mastered basic concepts to the complex represented by modern chess theory.
This book tries to help in that regard.
