I'm slowly working my way through the 40 positions I have been investigating since Dec 3rd. Now I have a Tree of Scenario's, I have something to give the more subtle knowledge a place. It is remarkable how commonly usable this knowledge is.
Did you for instance know: A target is protected by two defenders. When you trade off one defender, the other defender becomes immobile.
When this kind of knowledge is discovered, it feels as being subtle knowledge. But when you think about it, it is actually rather surprising that you have never realized it before. It is no rocket science, and very obvious. And remarkably commonly usable.
