Solution 1 The marked 10-stone Black group as yet has neither eyespace or shape, and that’s a serious detriment. But it’s offset by the fact that Black has the lower left corner, a live (two-eyed) group in the lower right, and unopposed stones in both of the upper corners. White has safe groups in the lower left and lower right corner, while his center group is strong (if not yet absolutely safe) because of the 3 trapped Blacks. On balance, if Black can save this large weak group without suffering too much damage to his positions above, both side’s overall chances are about equal. |
