The Further Evolution of Amateurs' Knowledge

(2011 - 2014)

2011 - When Writing and Editing the

First Edition of this Book

After the first edition of this book [LIT. 10] was in final proofs, we heard about a recently published book [LIT. 9], "Research on Weiqi Fayanglun", by Cheng Xiaoliu 6p. As far as we can see, for problem 120, the author's main results of interest to us are: He

- assumes that a black prisoner has been captured before the problem starts (#1; 771) /
   (#2; 778),

- uses the second throw-in at lower right (#1; 768) / (#2; 788),

- uses the "late", decisive oki at lower right (#1; 769) / (#2; 781),

- starts the endgame on the left side before further occupying Black's liberties at top right ( 767),

- gives the final result as jigo,

- does not mention the guzumi at top right,

- does not mention the hasami-tsuke at top right,

- and does not mention the tsuke at top left.
