  Difficulty: Beginner   Keywords: Life & Death

Hi I am really new to go and working my way through the exercises but I stopped at the fifth one


[Diagram]
Diag.: Black first, what is the result?


[Diagram]
Diag.: 1-3



[Diagram]
Diag.: Why 4?

In the solution White plays 4 and dies with 5.

Beginner Exercise 5 Solution

Below that solution there is an example in which White plays somewhere else and after Black connects the ko, White kills the three stones but Black can take away the big eye.

It seems to me that playing somewhere else is better than losing an extra stone: because in the second variation White gets four prisoners or something like that out of the situation... at least something.



lavalyn: If (and only if) the White group has an extra liberty, White 4 is the squeeze tesuji for life. Black can't create the killable big eye because suicide is disallowed.

[Diagram]
Diag.: 4 is correct SOMETIMES

Technically, in the given problem White should play a ko threat so that she may have the chance of taking the 1-1 point, then to capture the other Black stone - for two eyes. All other attempts to live will fail.



Thank you for your help. I was a little bit confused because in the situation 4 makes no sense but with an extra liberty it does.
