My experiment to take a complex tactical position and to generalize the solution to a higher cognitive level by means of narratives so that I can use it for other similar positions is a total succes. I'm confident that I will recognize the same idea in other positions. It changed my way of seeing such positions.
So what do I have now?
I'm not sure.
The problem was number 385 from Polgars book which contains 4158 problems. It took me 6 days to generalize the position. It was a demanding and hefty task which wore me out. To value if it is worth the efforts will depend on how often I will encounter a similar position. That is difficult to say, but since invasion is the the main goal of piece activity it must be good to recognize an invasion square by just looking at it.
On the other hand, now I'm busy with problem 386 of 4158 from Polgars book. After 2 days of hefty working I have investigated all winning lines. But again, if you ask me why is 1.d5 such killer move in this position (see below) and what are the characteristics so that you can recognize the same idea in other positions with a similar idea, I'm again at a total loss. So this might be going to be a looooong journey.
So I just continue at an easy pace to prevent me from wearing out. Practice will have to show if it is worth it. And who knows, maybe it becomes easier along the way.
White to move and win.
