monkey jump !

atulab: now black has 2 monkey jumps on both sides: we have created a symmetric position and listened to the proverb. The only question is: does white have a super-extra-cookie-cutting-tesuji-of-absolute-doom to separate black's stones ? we only have 4 points to consider so let's try them all !

[Diagram]

a

atulab: white loses a stone ... he certainly doesn't achieve much by doing so

[Diagram]

b

atulab: W2 can only try to lead to W4 because in itself it does nothing too bad, black has 2 liberties after W4 so it doesn't work ...

[Diagram]

c and d

atulab: W2 and W4 only reinforce black's middle stones.


xela: I will resist the temptation to create a new page called super-extra-cookie-cutting-tesuji-of-absolute-doom! However, it's interesting to have a quick look at why other moves fail...

[Diagram]

plausible, but wrong

atulab(adding W2 to B7): I'm not sure this is best but it creates a ko black can try to connect but then white creates another ko
