I remember well, as it was shortly having 15kyu grade on my own, that I was confrontated (positivly) with the term “Positional Judgment“… its that what probably we might call the skills of a “complete player“.
Naturally we beginners, double digit kyus (DDK) and single digit kyus (SDK) are not real masters of positional judgment. I think if we Go players take this “topic” into account of our own Go path and process of Go studies, we might keep straight on track not to loose too much time with “just playing around” and a disapointing and frustrating high loss quote.
PJ can give you a clear orientation about the tools which are needed to win our games.
