[Diagram]
Diag.: White lives

[Diagram]
Diag.: Main line

The tesuji here is White 3. After White 9, Black can't create a dead shape with A, because he is in damezumari. Note what a difference a black stone on the marked point would make.


[Diagram]
Diag.: Variation 1

White has to be careful answering 4 at 5 and not at 7. The strength of 3 is precisely that it already prevents the connection underneath.


[Diagram]
Diag.: Variation 2

Answering 4 at 5 is the only move. It appears as if White can falsen the eye after this sequence by throwing in again at 8, but White will simply connect at A.


[Diagram]
Diag.: Variation 3

Just to clarify: If black tries to leave white with a big eye by connecting at a (AlmostFilling the enclosed space with the dead shape of three in a line), white runs to b and claims a second eye at c. How should white then respond if black tries playing at d? That won't work for black; white runs along the second line and if black follows, eventually white can block on the first line and the resulting capture will give the second eye (at least). I don't think playing at e directly will work; seems like black sets up a ko that way. White could probably also escape in this sort of situation. -- KarlKnechtel


[Diagram]
Diag.: Variation 3


There are many ways for White to go wrong. Let's assume she takes 1 as the obvious move, but fails to see the tesuji of 3 in the main line.

[Diagram]
Diag.: Wrong 1

Black's hane produces a ko



[Diagram]
Diag.: Wrong 2

Black kills with the same hane.


[Diagram]
Diag.: Wrong 2 (variation by KarlKnechtel - there are some other similar ways too)
