Every chess player who wants to improve their level must study methodically as well as understand the basic principles governing the opening, middlegame, and endgame.

Most chess players place greater emphasis on opening theory. This is because it is easier to learn and can yield immediate results. However, these results primarily come from the opponent's ignorance rather than from our own abilities. Even chess coaches prefer to teach variations from various openings or simply tactical patterns. The reason is that more effort is required for the analysis of the middlegame and endgame.

Nonetheless, the theory of the middlegame and endgame is equally important. The difficulty lies in the fact that there are no absolute rules. It requires deep research into the ideas and logic of the positions. Furthermore, unlike opening theory, the theory of the middlegame and endgame does not change often with modern developments. It remains almost unchanged over time.

Therefore, anyone who wants to become a better chess player must change their approach. It is essential to understand the theory of the middlegame and endgame so that they can proceed correctly after the opening they have chosen.

This course series aims to present advanced training concepts, using the same methods that great chess players and many famous coaches have taught.
