Since your mental state can have such dramatic effects on your body, obviously your physical condition can affect your mental well-being. It follows that regular physical conditioning should be part of your overall chess training.

The business of the endgame is maneuvring to control critical squares, advancing or blockading passed pawns, preparing a breakthrough by the king, or exploiting the subtle superiority of one piece over another.

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

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.

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.

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.
