2010 - And Again the Missing Black Stone

(Referenced by 801)


As far as we can understand, in the introductory text to problem 120 in his book [LIT. 9], Cheng explicitly states that White has captured one of Black's stones on the first line on the right edge.
He also mentioned that it is important to consider this stone to get the correct outcome under Japanese rules.
