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.

If your opponent is short (on time), play just as you played earlier in the game. If you are short keep calm, I repeat, don't get flustered. Keep up the same neat writing of the moves, the same methodical examination of variations, but at a quicker rate.

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.

All candidate moves should be identified at once and listed in one's head. This job cannot be done piecemeal, by first examining one move and then look at another.

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.

Drawing general conclusions about your main weaknesses can provide a great stimulus to further growth.

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.
