Picture 3: Can you help me to figure out what the variations for B, E, F, G should be?
Also, do you think the answer for D (second diagram in picture 2) is reasonable and complete?

Thanks in advance.

In pic 2 it’s a bit short for low rated players. (Especially concerning the L&D of white group)

What I see is if white is cut, then white’s 5-stone group has to play one more move to make a life.

I checked a bit answer B by white, which was not obvious to me.


If black resist underneath, It’s a failure, he will finish being captured.


If black try to surround from outside like this It’s not getting well either.


Finally black is left with this move which produce a similar result as in the book.
