An example of a tombstone squeeze.

Attempt part 1

Attempt part 2, (revised)  

PeterHB: Discussion by MrTenuki refers to this superceded diagram:

[Diagram]
Attempt part 2  

MrTenuki: I'm not sure if W9 in the second diagram is correct, because black could resist like this:

[Diagram]
Attempt part 3  

Now a and b are miai for black...

[Diagram]
Attempt part 3 (Case A)  

Black connects and should be able to deal with the cutting point at circle.

[Diagram]
Attempt part 3 (Case B)  

If white plays W4 at a, black can connect the stones safely in a manner similar to that of Case A. If white plays at c...

[Diagram]
Attempt part 3 (Case B)  

And it's a ko (W8 at e). Sure, white takes first and will most likely win the ko, but why start a ko when you can capture unconditionally?

Attempt part 2, revised?  

By the logic of your opponent's good move is your good move, perhaps W9 of "attempt part 2" above should be played here? PeterHB: Suggestion accepted.
