Joachim's Ko-Semeai - Putting the Cart
Before the Horse (2013 - 2015)
0g - White Fills-in Her False Eye
in the Hanezeki
( 960) Black has a valid ko-threat at in the hanezeki, so White might consider filling-in her false eye in there at , before the ko begins. This move does not only steal Black's ko-threat, but simultaneously increases the Punishment Semeai Liberty Level by one, so forcing Black to connect the hanezeki's tail earlier than "usual". However, White's hopes will be in vain; we will reach a situation that is similar to that of FLAG 0c ( 961). |
|
White filled-in at , and has five liberties (2 * w, 3 * c), as "usual", against eight liberties for Black's group (3 * c, 4 * b, k). Black lost his ko-threat at , so we can expect that White will need three atari-ko-threats to win, one ko-threat less than with FLAG 0c ( 961). |

///: White has another option available to get Black's group below the Punishment Semeai Liberty Level: She fills-in her false eye at , instead of starting the ko with a move at . |

White filled-in at , and is still on the board. White has five liberties (2 * w, 3 * c), as "usual", against eight liberties for Black's group (3 * c, 3 * b, k, 1 approach-move liberty for the larger eye). |
