The study of typical plans is something that the leading grandmasters devote a great deal of time to. I would say that the most far-seeing of them devote as much time to this as to the study of openings.

In choosing an opening plan players think most of all of harmonious development for the pieces, but sometimes leave the development of the queen out of their considerations.

Experience and the constant analysis of the most varied positions builds up a store of knowledge in a player's mind enabling him often at a glance to assess this or that position.

The masters and grandmasters can be divided into three groups - the inveterate time trouble merchants, those who sometimes get into trouble, and those for whom the phenomenon is a very rare occurence.
