Velobici: The following is a problem from Weiqi Zhongji Jieti Xunlian. I dont know if the solution given in the book is wrong or if I simply can't read. The text beside the solution diagram is in Chinese.
If the book solution is indeed wrong, I'll move this over to the errata for Weiqi Zhongji Jieti Xunlian.

If White 'b' (atari), Black 'c' captures four White stones.
If White 'c' (atari), Black 'b' capture four White stones.
If ,

kill. After
Black is damezumari. (Found by Jantje).
