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

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.

I cannot think that a player genuinely loving the game can get pleasure just from the number of points scored no matter how impressive the total. I will not speak of myself, but for the masters of the older generation, from whose games we learned, the aesthetic side was the most important. -

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!

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.

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 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.
