I can’t cure myself of the habit of playing fast. Is there a cure? Do you have the habit of holding a stone while it’s the opponent’s turn to play and while you are thinking? If you are touching the stone, you want to play it, so you play fast or make unthinking moves. It’s not good manners, either. People are often quite unaware they have this habit. Please check to see if you do. One way to stop yourself from playing fast is to record your game while you’re playing. Normally, I don’t recommend this, as it affects your concentration, but it may be a good way of getting into the habit of thinking about each move. Taking a game record will also help you to study by reviewing the game. How about it?
