Middle-Game: Section 1. Pr. 2. B 2 play. B has a tesuji which enables him to capture 3 white stones. (Extra stones were added to the whole board (as envisioned by TnekKralc's limited 6k imagination) ;-) to account for the position presented in the book ;-) This is my second problem, so comments are welcome ;-)
