Race To Capture In The Corner
Path: GiveMeLiberties · Prev: OldSemeai · Next: BellyAttachment
White 1 and 3 initiate a race to capture or semeai which she will win due to the special properties of the corner.
If Black now connects at a, we have a fight between a group with an eye and a group without eye (RichardHunter calls it a Type 3 fight in his work on CountingLiberties). There are no internal liberties. White has three outside (exclusive) liberties, Black too, but White is to play.
It is tempting to play shibori but it is wrong, again due to the special properties of the corner.
This is one possible continuation. It is a Type 3 fight again. Black has one exclusive liberty in the eye (marked stone captured) and counts the internal liberty at a as well as the approach liberties b and c. That's four liberties. White counts the circled liberties: he has three. So even if White starts now (at c for example) she loses the semeai, but Black has to answer.
