question2
Yesterday I scored four wins to eight losses. On reviewing my games this morning, I realized that all my losing moves were ones that I had played instantly. In important situations, such as the life or death of a group or a cut, I impulsively play the first move I think of and lose. Before the game, I resolve to think carefully before I play, but when a fight starts I play important moves without reading. Is there any way to cure this bad habit?

answer
I play moves impulsively all the time and immediately regret them. It’s important to follow your intuition, but not taking any time to think on important moves, involving life and death, for example, raises the odds of failure because you are not analysing the opponent’s moves. It’s better to read a few moves ahead rather than relying on your intuition.

The best way to cure the habit of playing too quickly is to study life-and-death problems. You have to work out the various ways in which the other side can resist, so it takes time to work out the answer. If you continue studying life-and-death problems, you may naturally get into the habit of thinking at important points in your games.
