April 29th Elementary Tsumego. Black to Play

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

[Diagram]

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 her upper stones and Black would be dead. Am I right?

[Diagram]

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]

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]

Variation Continued...

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

[Diagram]

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.
