Solution 5 The key here is to recognize that, at least for the moment, the fight on the left side is over because both sides are stable, and the two isolated Black stones in the lower left aren’t big enough to warrant immediate action.
That in turn means that White’s response to the marked Black stone must without fail be played elsewhere! (In this position, that means on the right side.)
Of course it will make a major difference in the game whether or not that tenuki is played on the best point. But for the purposes of this chapter’s focus on when fighting is or is not appropriate, count your answer as correct if you recognized that a tenuki is called for!
