A chess match is a chain of moves. It keeps growing little by little as players respond to their opponent’s moves. Each move leads to a different position, each position leads to a new move.

Moves are the result of reasoning. Both players desire to make the best possible move to win the game.

How they do it? First of all he or she observes the position and tries to think about its special characteristics, facets and the relationship between them and the context. Then the player organises the information. Having done that, he already has a limited number of possible moves that can be the best, studies the consequences of each one of them and finally chooses one of them.

To solve all this problems properly the player needs to have some skills, knowledge, methods and a developed will to do all this work.

The skills are learned and improved with continuous practice. Practice creates the master.

During this course some exercises have been purposed that surely have developed some skills among the ones who have tried to solve them.

Knowledge and methods go together.

Chess has a unique characteristic that makes it different from the rest of the games: It has developed a theory.

How to develop that theory?

Given that a chess match can be recorded and then played back, errors committed can be studied in order to not commit them again.

Books with collections of matches and recommendations have been written slowly along history.

Since the beginning of the mechanical printing chess books already existed but chess writings existed even before Gutenberg's mechanical printing.

That was the way a theory that joined all the experience and opinions from the most important players of the world was developed.

While some chess players choose to learn from their own experience and years of practice, others, the ones who base their training on the books they read could improve in a month basing their learning on the masters experience accumulated in decades, and defeat them.
