Tilwen: Sure, but in a go game a lot of moves are correct, here it seems that only one is expected, but for what reason or what plan ? I am not sure - maybe I am not strong enough, about 2d KGS - that everyone would agree that "the only" correct sequence here is "the only" best play. Then either the problem is very difficult, or it lacks explanations, or I am not strong enough ;-)
d4rkm4tter: On a scale of 1 to 4, the problem has difficulty 2 and the hint is "How can black/white secure his two stones?" I added the hint.
