Snapback Problem 31 / Solution
Sub-page of SnapbackProblem31

[Diagram]
A threat of a snapback

By playing W2, White creates a 4 point (miai counting) threat of a snapback with W3.


[Diagram]
Correct local move

B1 is the correct local move, saving Black's two stones and threatening B2. Later B5 and W6 are worth 1 point miai.

Black is 1 point better off than in the first diagram.


Tenuki is another option.

Tenuki

W1 - W3 gains 1.5 points in gote. Later B6, W7, B8, and WC are 1 point moves. This is the price of Black's tenuki and it is not large.


Carcer- just a thought isn't the snapback 0 points? white gets two points and black also takes 2 points?

[Diagram]
Snapback

Bill: The snapback is worth 4 points. If White captures the 3 Black stones she gets 8 points in gote (the 3 BC stones plus the 3 points they occupy, plus the 2 [circled point] points), while if Black saves them those points are not territory. Before the snapback White can claim 4 of those points. If she plays at W1 she gets 4 more points, while if Black plays there he takes 4 points away.
