Joachim's Ko-Semeai - Putting the Cart
Before the Horse (2013 - 2015)
5c - White Takes the Guzumi Point
( 981) (Referenced by 408) Here we will analyse what will happen, if Black's kikashi of is played so early that White can occupy the guzumi point of immediately. Black will be able to capture White's two -stones. We will take / off the board, in order to allow the sequence shown next. |

Black captures two of White's stones in gote, so that White can stop Black from getting a second eye for his group with a move at . |
|
White's group has nine liberties (2 * w, 7 * c). Black's group has twelve liberties here (7 * c, 4 * b, k), three liberties more than White. Again, there is no internal ko-threat for Black. In principle, we have a situation like in the case before, with White having lost a move. So we can expect White to need three atari-ko-threats. |
