Now I have formulated the narrative of the cage, there are a whole lot of chessproblems that fall into this description. Every mate, to be precise.
I'm well aware that what I try to tell now probably will sound very vague, but since it is important I hope you are willing to put some effort in it to understand what I'm trying to say. Feel free to ask.
There is a close relation between narratives and chess vision. A narrative is the first stage of learning something new, chess vision the second. Take for instance the narrative of the king in the cage. The narrative tells that there are 3 types of fabric of which the cage is made:
- The edge of the board (physically visible)
- The pieces of the opponent (physically visible)
- The squares covered by your own pieces (chess vision needed)
Due to the idea of the cage I was able to run through the advanced problemset of the CD intensive course tactics II of Renko. The whole CD contains only problems with forced lines. That is to say, every move is a check. Every CD of Renko focusses on one or a few tactical themes.
Now I started with the forced checkmates of masterlevel. These are more complex than the advanced level. Hence it forces me to create new narratives which must explain why these problems are more complex. This is what I found:
Sofar I encountered 3 layers of chess vision:
- The squares covered by my present pieces (part of the present cage)
- The squares covered by a piece of me in the future (part of the future cage)
- The squares covered by the enemy (limits the places where I can put my pieces hence my ability to create the future cage)
It is not quite clear how to work around this limitation in a practical way.
