In particular, Positional Judgement 2 has examples for every use of influence listed in http://www.lifein19x19.com/forum/viewto ... 57#p205357
The most important uses are also illustrated shortly in Easy Learning: Joseki. Joseki 2 - Strategy defines degrees of thicknes and influence and Positional Judgement 2 proceeds research by simplifying a definition of types of thickness. There are books by other authors with examples of using influence but I have seen none that comes close to the systematic study in my books. With respect to thickness and influence, I have learnt ca. 10% from other media, online authors or pro-playing teachers and ca. 90% from researching using professional games to generalise the theory, which is now in my books.

Charles, territory and influence are insufficient. As I have explained in a different thread, dynamic positional judgement must consist not only of connection and life statuses and current influence, but also of: development directions; neutral stones; statuses of stability and of life and death of imagined invasion groups; options; aji; imagined reductions and invasions; local potential; thickness; imagined best use or transformation of influence, thickness and potential; imagined good fights.

Doubtless these are all necessary; but are they sufficient? Please give adequate detail.

The whole book Positional Judgement 2 - Dynamics provides the adequate details for each mentioned aspect. Some of them also rely on reading, counting or positional judgement of territory (see Vol. 1). Althogether, the aspects provide 95%+ of what is sufficient in practice for dynamic positional judgement, IMO, according to my observation in my own games and the related study of professional games.
