It is hardly useful if you trustingly play through variation after variation from a book. It is a great deal more useful and more interesting if you take part actively in the analysis, find something yourself, and try to refute some of the author's conclusions.

It is not possible to become a great player without having learned how to analyse deeply and accurately.

I feel that it is no less interesting to be a trainer than to play oneself. I even take greater delight in the tournament successes of my lads than I do in my own.

In positions of strategic manoeuvring (where time is not of decisive importance) seek the worst-placed piece. Activating that piece is often the most reliable way of improving your position as a whole.

Emotional instability can be one of the factors giving rise to a failure by chess players in important duels. Under the influence of surging emotions (and not necessarily negative ones) we sometimes lose concentration and stop objectively evaluating the events that are taking place on the board.

As a rule, pawn endings have a forced character, and they can be worked out conclusively.

Training in analysis (like any other form of chess training) should be treated very seriously.
