Time trouble is blunder time.

Go through detailed variations in your own time, think in a general way about the position in the opponent's time and you will soon find that you get into time trouble less often, that your games have more content to them, and that their general standard rises.

Once we have chosen the right formation in the centre we have created opportunities for our pieces and laid the foundation of subsequent victory.

If you study the classic examples of endgame play you will see how the king was brought up as soon as possible even though there seemed no particular hurry at the time.

Once there is the slightest suggestion of combinational possibilities on the board, look for unusual moves. Apart from making your play creative and interesting it will help you to get better results.

It is better to follow out a plan consistently even if it isn't the best one than to play without a plan at all. The worst thing is to wander about aimlessly.

There is no doubt that the reason for my awful oversight was over-confidence that sapped my sense of danger. So that is where to look for the cause of bad blunders - in the exulting feeling of self-congratulation.
