Tsumego From Games 24 / Solution

Solution

The main line, as often seen in life-and-death problems, is this sequence from B1 to B7.

Here, B3 reduces the number of liberties of the W2 chain to only two, so B5 becomes an atari which nullifies the possible eye at W6.


[Diagram]

Solution

If W2 is played, then B3 connects and White does not have enough eye space to make two eyes.

[Diagram]

Optimal Success?

Arieh Is this the right sequence for black to kill after 4?

[Diagram]

Continuation

Arieh Where 3 can be played at any time in the future regardless of 2.


[Diagram]

Failure

B1 is a failure because it results in a ko.


Discussion below may need some cleanup or additional context.


[Diagram]

A few moves

jvt W3 seems to denote a willingness to save the corner, but then (surprise) the tenuki at W5 lets Black kill it.

[Diagram]

13 moves later

jvt: 13 moves later, W1 does not revive the corner but creates endgame aji.
