Principle A) Defend your weak stones
Principle B) Sacrifice your unimportant stones

Even though these principles may be contradictory, I think teaching along these lines probably facilitates learning for most students. Particularly if followed by clear examples of both cases.

Principle AB) Defend your important weak stones

This is a more comprehensive but also more complicated principle. Teaching along these lines is difficult, but perhaps facilitates learing for some students.

In either case, I suspect real learning depends on following up the statement of principle with a good selection of relevant examples. Then the learning would likely be good either way.

I'm trying to understand Robert's vehemence. Perhaps every euro spent on this book is a euro that won't get spent on his. Sad, really.


I have known Robert online for almost 20 years. He is not a mercenary. He is a dedicated seeker after truth. Before writing his recent books he spent untold hours on the thankless task of attempting to decipher the Ing rules and the Japanese rules and to propose his own rules of go. He may have capitalized upon his rules expertise in some way, but if so I expect that it is to the tune of pennies per hour. Robert has a unique approach to go which is based upon ascertaining principles instead of picking up intuitive notions through examples and play. That his books have been well received indicates that he has been able to explain his ideas well enough to his readers and students, and that they find them valuable. :)

As far as defending weak groups is concerned, when I was a beginner I followed Korschelt's rule of thumb, one eye and access to the center, which he apparently learned from Murase Shuho. It worked pretty well, although pros sometimes leave even weaker groups around. :) This rule of thumb gives a reasonable idea of when a group is strong enough to leave undefended.
