All Chess players should have a hobby
Drawn games are sometimes more scintillating than any conclusive contest.
No one ever won a game by resigning.
It is said that an ounce of common sense can outweigh a ton of 'variations'.
As for me, I am unfortunate enough not to posses a happy temperament like Najdorf, who views every happening in a rosy light and avoids any possibility of self-criticism. I am one of those unlucky skeptics who never overlook the dark side of even the happiest experience.
In chess, there is only one mistake: over-estimation of your opponent. All else is either bad luck or weakness.
