- Time (duplo attack)
- Space (trap, mate)
- Function (defense, overloading)
The big tree of motifs provides an ideal framework to give other knowledge a solid base to be hanged upon, in a way that we can find back that knowledge. For every single problem to be solved, the PLF (PoPLoAFun) system is useful. This doesn't mean that the sole use of the PLF system is enough to solve every problem. The system needs extensions. The coming time I will try to inventory which extensions are needed. You have to be a little patient, since during the inventory it is too early to draw already any conclusions. I presume.
Let's elaborate on the assault one more time again.

The PLF system gives you a clear idea where to focus your attention: on the pieces that lack mobility. Caused by time, space and or function.
In order to solve a position like this, you need to have a special skill. You need to be able to see the room for manoeuvre of the white king. You need to be able to see the "cage" or "box" around the white king. It isn't necessary to see it right from the first move, but when you chase the white king, there will come a moment that you must recognize this cage:
