- c is disaster for white. After black turns to the left, the sequence
- to 7 traps a cutting group in a simple ladder (6 anywhere else lets
- black out):

- If White turns South instead, Black forces him into a dead end. White
- cannot get the extra liberty needed to tennuki, and is forced to return
- to the north, giving Black the ladder as above.
-
- As far as I can see White is done for.
