Sometimes players need to gain time on the clock by repeating the position, but most often its purpose is to wear down the opponent psychologically.

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

I always urge players to study composed problems and endgames.

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.

According to such great attacking players as Bronstein and Tal, most combinations are inspired by the player's memories of earlier games.

Under no circumstances should you play fast if you have a winning position. Forget the clock, use all your time and make good moves.

Patience is the most valuable trait of the endgame player.
