xela: Is the problem diagram correct? The version on the uliGo web site has a white stone at 'a'; this is also the case at [ext] http://www17.plala.or.jp/trachan/zgo0133.htm (a subpage of [ext] http://www17.plala.or.jp/trachan/gokyou2.html). I don't have an actual printed book of these problems: is someone else able to check? (Apologies to unkx80: you did such a nice job of solving the problem as it stands!)

unkx80: Maybe you are right. My solution attempt does not matter...

xela: Update: the diagram in World Weiqi Masterpieces of Life and Death agrees with the web sites listed above, so I've changed the diagram here to match. (The marked white stone is the one that was missing before.)
