To put your own stones in atari

[Diagram]
Diag.: Example

From the CranesNestTesuji. The circled spot is the last liberty of the chain of five Black stones surrounding it. If Black wants to protect his stones from being captured ...


[Diagram]
Diag.: Example

He creates a lump of seven stones, which still have only one liberty left. Thus Black has put his own stones into atari: next, White will capture them all at a.



[Diagram]
Diag.: Example 2

DougRidgway? -- In the example above, the black stones were already in atari, so the mistake doesn't change much. Here's an example from one of my games where the consequences should have been more serious. Black played at the marked point. I was White, too bad I didn't spot the atari.



[Diagram]
Diag.: What is the worst response to Black 1?

Here's another one. White has lots of good responses to Black 1 (consider a, for instance, or perhaps tenuki). What is the pessimal choice?


[Diagram]
Diag.: Oops.

This was where I played.
