Rationality brought up a very good point. Read here.
I was thinking the same thing when I coined the term "imagined fear" in the "inner child" work. I believe that instinct; the fight or flight response; the law of the jungle argument is inappropriate in the mastery of chess. If you look carefully, you will see I have argued that no one is coming at you with a knife, no lions waiting to devour you. In a healthy competition of chess all you have is imagined fears that come from your mind. And the ego is the guardian of imagined fears.
Now I believe that intuition is the correct tool for chess. Intuition works this way. You can only be intuitive when you have knowledge. It cannot come from a vacuum. It's a sudden joining of the dots, a sudden epiphany. And epiphanies only come when the mind is still. Thank you rationality for bringing this up.
Note: And since it is not easy to "undo" instinct, it requires training.
