Chapter Eleven. Cramp 11.1 Two-point extension: the placement {{Dia 708}} {{Dia 709}} This chapter gives the other side of the story on the two-point extension. When it is cramped by two White stones, as shown in the left-hand diagram, it can be attacked in many ways.

Chapter Fifteen. Sabaki The sabaki concept is one of the most important developed in the Japanese tradition of professional go. {{Dia 856}} {{Dia 857}} This example occurred in 13.3. White should have planned how to play before arriving in this position. (Left) Black has played an extra marked stone, to cover the possible cut in the attach-extend formation.
