I have seen a series of net problems like the one below on a Japanese web site :
![[Diagram]](../../diagrams/33/2d9697d0d691061edca46093cb8ae957.png) | Black to play |
![[Diagram]](../../diagrams/23/95892a8db4c3c2ed2e344b4b0378b5a2.png) | Black 5 is a net |
Even though it does not prevent White from increasing its number of liberties, prevents White from escaping.

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

Alex Weldon: Probably worth showing for beginners what happens if White tries to atari her way out. If , expecting Black to connect at so that she can then escape by playing at , Black squeezes with and . White connects with at the marked point and Black catches her in a ladder with , and . 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.

Mef: If the ladder is bad for black, I think he can set up a ko with . If white declines to fight the ko, black has a chance to set up a different ladder, which may or may not work depending on where exactly the original ladder breaker is.
