Errors have nothing to do with luck; they are caused by time pressure, discomfort or unfamiliarilty with a position, distractions, feelings of intimidation, nervous tension, overambition, excessive caution, and dozens of other psychological factors.

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

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 always urge players to study composed problems and endgames.

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.

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

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