Hitachi Number 314 Easy Solution
   

[Diagram]
Diag.: April 29th Elementary Tsumego. Black to Play

Noel Herradura: Okay, here black has one guaranteed eye. Now how to make the second one...


[Diagram]
Diag.: Noel's First Attempt... total failure.

Noel Herradura: My first instinct is to connect the two black groups, of course. But then white would connect to his upper stones and black would be dead. Am I right?


[Diagram]
Diag.: Noel's Second Attempt

Noel Herradura: So the first priority is to prevent white from connecting. White then ataris with 2, black extends with 3. White then plays 4 to attempt to separate black.

But after black plays 5, white should play elsewhere since black has secured three eyes.

Hey hey... how was that? Did I miss any variations?


[Diagram]
Diag.: Variation

Noel Herradura: D'oh! I forgot this variation! What if white ataris with 2 instead? Black cannot connect his ataried stone because white would connect with the two marked stones...


[Diagram]
Diag.: Variation Continued...

Noel Herradura: Continuing the variation which leads us to the next diagram...


[Diagram]
Diag.: Variation Continued part deux

Noel Herradura: Now it is in both players' interests to play bigger moves elsewhere. White has a ko threat at a that she can use later.
