When you defend, try not to worry or become upset. Keep your cool and trust your position - it's all you've got.

There is nothing wrong with trying to exploit the natural human tendency to become impatient when forced to play a boring position.

Agreeing to draws in the middlegame, equal or otherwise, deprives you of the opportunity to practice playing endgames, and the endgame is probably where you need the most practice.

I had a slightly inferior endgame that probably should have been drawn, but Kortchnoi kept torturing me with little threats until finally, exhausted and exasperated, I made a losing mistake.

I remember being with a girlfriend who asked me to look over some chess openings with her. I instantly fell asleep. I found that I could always take a nap in any situation by just looking at some opening variation - my eyes would shut right away.

There is no doubt that Bronstein's shrewd understanding of chess psychology was crucial to his success. Without it, his impetuous style and technical flaws might have relegated him to a minor career.

I always urge players to study composed problems and endgames.
