I can remember a case where Capablanca worked out an impressive combination, but then chose to make a simple move in answer to which his opponent resigned at once!

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.

If you study the classic examples of endgame play you will see how the king was brought up as soon as possible even though there seemed no particular hurry at the time.

In analysing complicated variations one must examine each branch of the tree once and once only.

You will already have noticed how often Capablanca repeated moves, often returning to positions which he had had before. This is not lack of deciciveness or slowness, but the employment of a basic endgame principle which is 'Do not hurry'.

Once in a Moscow chess club I saw how two first-category players knocked pieces off the board as they were exchanged, so that the pieces fell onto the floor. It was as if they were playing skittles and not chess!

If you can play the first ten or fifteen moves in just as many minutes, you can be in a state of bliss for the rest of the game. If, on the other hand, Bronstein thinks for forty minutes about his first move, then time trouble is inevitable.
