Shortage of liberties exercise 1

    Keywords: Tactics, Problem

Based upon 1001 Life and death problems; Page 169, problem 693, solution diagram

First posted as an alleged erratum.


Black B1 is the vital point of White's eye shape. If White W2, Black links up with B3.


... continuing from Diagram 1, White sacrifices a stone at W4, placing Black in a shortage of liberties.


If B5, capturing the White sacrifice stone, White plays W6, threatening to capture either two Black stones or four Black stones. Thereby forming two eyes.

Unfortunately, the alleged erratum is an erratum in itself.

White in self-atari  

W6 had in fact placed the entire White group in self-atari, so B7 can capture the entire White group.

The irony of it is that it is White that suffers from shortage of liberties (because White cannot play at W6), not Black suffering from shortage of liberties as stated in the alleged erratum.

DuEm6: This is one strange page. Certainly not an exercise. Was it a mistake? And the discussion of the mistake was deleted by the last diff.
