Various Kikashi in the Hanezeki

(2007 - 2011; 2014)

(Referenced by 37)


In this chapter, we consider some earlier commentaries concerning the (hane-) seki in the lower right corner. We suggest some improvements, and attempt to illuminate some things that we could not understand fully. Basically, we explain various exchanges, which could make life easier for Black.
This chapter was created prior to the development of the idea of Joachim's Ko-Semeai. Please note that we have not added substantive discussion of this ko-semeai here.
