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. Yet the Queen is the most valuable and important piece and the whole outcome can depend upon how successfully she plays her role.

Here is a definition which correctly reflects the course of thought and action of a grandmaster: - The plan in a game of chess is the sum total of successive strategical operations which are each carried out according to separate ideas arising from the demands of the position.

In order to become a grandmaster class player whose understanding of chess is superior to the thousands of ordinary players, you have to develop within yourself a large number of qualities, the qualities of an artistic creator, a calculating practitioner, a cold calm competitor.

The main thing that develops positional judgement, that perfects it and makes it many-sided, is detailed analytical work, sensible tournament practice, a self-critical attitude to your games and a rooting out of all the defects in your play.

Just as the pianist practices the most complicated pieces to improve the technique of his fingers, so too a grandmaster must keep his vision in trim by daily analysis of positions with sharp possibilities, and this applies whether he prefers such positions in his play or not.

When you have finished analyzing all the variations and gone along all the branches of the tree of analysis you must first of all write the move down on your score sheet, before you play it.
