Beginner Exercise 5 Solution
  Difficulty: Beginner   Keywords: Problem

lavalyn 17k trying to figure out how to make SL diagrams.

[Diagram]
Diag.: A nice ko for Black

Black can make a ko where he captures first.


[Diagram]
Diag.: Black 1 is already at the vital point.

Attempts to defend the threatened corner stone does not work. (White dies in gote.)


[Diagram]
Diag.: White got hosed.

The squeeze does not work because of damezumari.

A nice one-sided ko (picnic ko) if there ever was one.



[Diagram]
Diag.: White got...hosed?

White 1 and 3 die, is that group not alive?

SAS: What group? Black 5 captures all White's stones...



unkx80: This solution is perfect. I'll just add a bit more. =)

Actually this one is also a kind of bent four in the corner.

[Diagram]
Diag.: When black wins the ko.

If Black wins the ko, he will connect at 1. The white group becomes a bent three big eye and dies.

RexWalters: This is especially important if White has one more liberty (say the marked stone is missing). In this case the squeeze play above does give White life.


[Diagram]
Diag.: Failure.

Black 1 is at the wrong point; White 2 lives.



[Diagram]
Diag.: If white wins the ko.

Of course, black still has to win the ko fight, or it was all for naught...
