Snapback Problem 12 / Solution

Sub-page of SnapbackProblem12
[Diagram]
Save black stones  

Scartol: B1 is the move for Black, threatening the snapback throw-in at a. White can't threaten the double-capture at b, because Black will immediately take and have the extra room to make the snapback happen. Black emerges with a victorious grin.

Fhayashi:W2 is futile, right? Isn't it better played elsewhere?

kishi Can white recover this corner in any way? Or save itself?

unkx80: The short answer is, no.

Save black stones  

abcd_z: The solution I can up with had a slightly larger snapback, but it amounted to the same thing. White is dead, and an attempt at a would lead to a snapback at b.

HolIgor: Answer to the last diagram

[Diagram]
Black fails  

The variation at the last diagram does not work. White captures and wins the semeai by the virtue of an eye against no eye. If Black a then white captures with b, if Black b then white plays c and yet black is short of liberties. White has all the time in the world to capture.
