One Space Low Pincer Ko
  Difficulty: Dan level   Keywords: Joseki, Life & Death, Ko

[Diagram]
Diag.: starting position

In the page on the OneSpaceLowPincer, it is mentioned that this corner is ko if black plays first. There are two ways to start this ko, but one is clearly better than the other.


[Diagram]
Diag.: first ko

The 'wrong' way to start a ko is by this sequence. If black wins the ko at 1/6, white dies. If white wins it, she lives.


[Diagram]
Diag.: second ko

The 'correct' way to start ko is with 1 and 3 here. This ko is more pleasant to black than the previous one for two reasons:

  1. In this diagram, if black wins the ko, he can take the stones off the board. This means that white has no aji left whatsoever. In the other diagram, a little amount is still left.
  2. In this diagram, white has to make the first ko threat, whereas in the other diagram, black does.
