There are exceptions (and in this sense the guidance of an instructor, or the reader's own common sense, is important), because if the first move or two produce such a judgment, the solver is expected to provide additional concrete lines that enrich the solution. Chess is not a mathematical science and allows for various interpretations.

The ideal complement to this formula is, as many great masters recommend, for the player to develop and perfect their tactical and strategic skills by solving numerous exercises, specially selected for their usefulness.
