Why does Black lose?
There are many things about chess that I will call "chess secrets", that are never explained in chess books and can't be explained as they occur on a subconscious level.
Most chess books are written by chess grandmasters and for them to see plans and concepts comes natural and they often assume that the reader sees what they see. They read a position like a newspaper, and I mean, that they read it fast and clear and the amateur looks at the board and sees nothing most of the time.
They feel and see the right concept in a given position immediately and start calculating, whereas normal players -non-grandmasters- as we are, have to virtually force themselves mentally to illuminate themselves by going through all this, step by step, hammering each concept into our minds to grasp and never forget these ideas.
Chess is not only about memorizing hundreds of opening lines. There is something below the surface that is hard to grasp. Just try to understand the following game. Fritz Chess Program versus No Name. Try to understand why Black has drifted into a lost position. Black has played well, you think....yeah, that's what YOU think.
Both players have developed their pieces. So far so good. BUT what is disturbing in my mind is that Black has not castled but played b6 very early. Well this might mean nothing yet but it POPS UP in the mind of a fine-tuned player. You just notice it. Then you feel the urge to use this to your advantage and try to seize the initiative in the center, where else, playing e4.
Hey! Don't make a silly waste-of-time-move now like a3 or h3 or Bd2! or some other stupid thing. I must formulate a principle to grasp for you or we will get nowhere!So, here it is!
