Rh by the sacrifice of stones. This series is taken from Korschelt, and the position as it arose in actual play is shown on Plate 10, depicting a complete game. In Plate 3, Diagram, the white group is shown externally surrounded, and the black stone has just been played at S 9, rendering the group hopeless. The same group is shown on the opposite side of the board at Plate 4, Diagram, but Black has added three more stones and could kill the white group on the next move. Therefore, White plays at A 12, and the situation shown in Plate 4, Diagram, arises, where the same group is shown on the lower edge of the board. Now, if it were White's move, he could save his group by playing at J 2, and the situation which would then arise is shown on Plate 4, Diagram, where White has three perfect "Me," one more than enough. However, it is not White's move, and Black plays on the coveted intersection, and then adds two more stones until the situation shown in Plate 4, Diagram, arises. Then White must again play at S 8 in order to save his stones from immediate capture, and the situation shown at Plate 5, Diagram, comes about. Black again plays at J 18, adds one more stone, and we have the situation shown in Plate 5, Diagram, where it is obvious that White must play at C 11 in order to save his group from immediate capture, thus leaving only two vacant spaces. It is unnecessary to continue the analysis further, but at the risk of explaining what is apparent, it might be pointed out that Black would play on one of these vacant spaces, and if White killed the stone (which it would not pay White to do) Black would play again on the space thus made vacant, and completely surround and kill the entire white group.
