The typical training mistake you are probably making (and need to learn to avoid)

Once the paradigms and fundamental procedures of chess training are understood, it is incumbent upon both instructor and student to safeguard the correctness of this process, placing particular emphasis on the orientation of the will that sustains it.

In this regard, there exists a deeply ingrained error in the way most chess players conceive of training—an error that must be recognized in order to avoid the harm such a misconception can bring.

Curiously, it is not usually related to the number of study hours, the quality of the books, or the difficulty of the exercises, but rather to an idea that seems harmless:

Believing that studying consists of learning "new things" in order to “apply them directly” in games.

It sounds logical. Yet the reality of the board works differently.

A game never pauses to ask the player whether they remember a classic sacrifice, a strategic maneuver, or an opening line. Real positions rarely reproduce the studied examples exactly. On the contrary, they present a unique blend of tactical, strategic, and positional elements that conceal—sometimes almost entirely—the familiar patterns.

In other words, the problem is never simply recalling an idea. The problem is recognizing that the idea is relevant in a completely new position.

And that difference completely changes the purpose of training. The didactic key lies not in accumulating isolated concepts or tactical motifs, but in cultivating the judgment by which those concepts and mechanisms are discovered during analysis. That is, priority must be given to the application of the mental procedure that enables the recognition of chess patterns even when they appear “disguised” within entirely different configurations.

Do not train concepts: train your way of thinking

In chess, there are practically no new tactics or unprecedented strategies. The game constitutes a closed system whose fundamental principles manifest themselves through infinitely diverse configurations. All the elements of each tactical‑strategic motif can be studied in encyclopedic sources that break them down according to the multiple modalities and subtleties of abstract and combinatorial thought. Yet the true challenge of such resources lies less in the variety or uniqueness they may offer than in the perspective from which their contents are interpreted.

What is truly difficult in this regard is not to expand one’s repertoire of knowledge indefinitely, but to develop the mental approach that allows one to distinguish, among hundreds of possibilities, which of those principles are relevant at any given moment.

For this reason, the real object of training is not openings, endgames, or tactical motifs in themselves. It is the exercise of the cognitive procedure that brings them into operation.

Each position demands—consciously or unconsciously—a similar sequence:

Observe → Assess → Select candidate moves → Calculate → Evaluate → Decide

That process is the genuine muscle that must be strengthened.

Memory does not direct analysis

Many players try to solve positions by asking themselves: “What do I remember having seen about this?”

Strong players usually invert the order, asking first: “What is actually happening in this position?” Only after answering that question do they make use of useful memory. The difference is enormous. It is not memory that directs analysis—it is analysis that activates the appropriate memory.

The real risk: confusing recurrence with repetition

To affirm that chess is a system of recurrent principles does not mean that there comes a moment when “everything is already learned.” Such an interpretation can lead to one of the greatest enemies of progress: the illusion of "unquestionable competence".

What refutes that illusion is precisely the fact that, although tactical, strategic, and technical foundations remain essentially constant, the concrete configurations in which they manifest are practically inexhaustible. Each game reorganizes those same elements in a different way, forcing the player to reinterpret them under new restrictions, priorities, and resources—always requiring attention to detail and an investment of competitive and spontaneous effort that goes far beyond the routine repetition of rehearsed ideas.

For this reason, advanced learning ceases to consist in accumulating an endless list of “new” concepts and instead focuses on something far more demanding: continuously refining the quality of one’s thinking when faced with unprecedented conditions that challenge the effectiveness of already‑known principles.

A master does not progress because they “discover unknown tactics.” They progress because they recognize more quickly the subtle relationships between familiar patterns, evaluate their interactions with greater precision, and calculate more deeply the consequences of each decision.

In this sense, chess never stops teaching. Not because its laws change, but because the richness of its combinations repeatedly tests the clarity of the player’s thought.

True stagnation begins when one ceases to believe that thinking can continue to be perfected. As long as new positions exist, so too will opportunities to observe more carefully, assess more precisely, calculate more deeply, and decide with greater judgment.

A more realistic training

If the goal is to refine thinking, then the classic cycle of “study, practice, and correct” proves insufficient.

A training regimen more faithful to reality could be summarized as follows:

<Understand> a principle deeply, rather than merely memorizing it.
<Simulate> positions by applying a disciplined protocol of analysis.
<Recognize> patterns during practice, without expecting exact replicas of what was studied.
<Adapt> known principles to unprecedented situations.
<Audit> one’s own mental process after each game to discover at which stage the error appeared (in the method of thinking rather than in the specific moves).

<Refine> that particular phase of thought, instead of simply accumulating more information.

The difference between knowing and playing well

Many amateurs are familiar with the same concepts as much stronger players, yet the difference rarely lies in theoretical knowledge. It lies in the quality of the process by which that knowledge is selected, combined, and applied under the shifting conditions of a real game.

That is why progress does not depend solely on studying more. Above all, it depends on thinking correctly. And perhaps that is the most important shift in perspective a chess player can incorporate at every stage of their training.

"Some things are really hard to do, almost impossible to do, like playing perfectly in extremely complicated positions. But it really bugs me when I miss things that I really shouldn't have. I am always going to make mistakes. I don't have any illusions that my understanding of chess is perfect or anything like that. It's just that I have to work on relatively simple mistakes. When I can lower the percentage of such mistakes then things are going to be much better."
