Life and death example 1 "we do not take three"
Black Yotsuko, white Kazuko are "becoming permanently free from danger stones" together; by Article 8 "cough stone."
Even if FIG. 1, FIG. 2, black have their Yotsuko stolen, Kuroishi who is not taken can thereby occur.
Even if FIG. 3, FIG. 4, FIG. 5, white Kazuko are taken, we can thereby produce stone which is not taken.
