Net example 7
  Difficulty: Advanced   Keywords: Tactics

jvt I have seen a series of net problems like the one below on a Japanese web site :

[Diagram]
Black to play

[Diagram]
Black 5 is a net

Even though it does not prevent White from increasing its number of liberties, B5 prevents White from escaping.


[Diagram]
Continuation

W10 at B1. Then White is caught in a ladder (Black 11 at a).


[Diagram]
Another continuation

Alex Weldon: Probably worth showing for beginners what happens if White tries to atari her way out. If W1, expecting Black to connect at W3 so that she can then escape by playing at B4, Black squeezes with B2 and B4. White connects with W5 at the marked point and Black catches her in a ladder with B6, B8 and B10. As a question to stronger players: Is there still a way for Black to capture if this ladder is also no good for Black (some ladder breaker stone that we can't see here)? I don't see it.



Moved from loose ladder.
