It is annoying that the rules of chess do not allow a pawn to take either horizontally or backwards, but only forwards ... This psychological tuning is ideal for attacking purposes, but what about for defence?

What the devil possessed me to reply 1. ... e5?? I compltely forgot that Spassky, like Spielmann in the past, very much likes to play the King's Gambit.

The essence of Chess is thinking about what Chess is.

But whatever you might say and whatever I might say, a machine which can play chess with people is one of the most marvellous wonders of our 20th century!

If you have made a mistake or committed an inaccuracy there is no need to become annoyed and to think that everything is lost. You have to reorientate yourself quickly and find a new plan in the new situation.

There is no disputing that in the eyes of Schlechter, Teichmann or even Rubinstein, the backward pawn was something more substantial than lively piece play, but in our day the latter is more often preferred.

A game of chess is not an examination of knowledge; it is a battle of nerves.
