You must not let your opponent know how you feel.

Experience and the constant analysis of the most varied positions builds up a store of knowledge in a player's mind enabling him often at a glance to assess this or that position.

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.

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.

Drawing general conclusions about your main weaknesses can provide a great stimulus to further growth.
