Tsumego From Games 60
From a game between two 2 kyus on DGS in July 2005.
tderz: This very interesting problem derives from a game of a befriend 2 kyu on DGS.
As in real life - this problem has several stages.
- probably white does not need make another move right now, because white a and b are miai for an eye, the other one being in the corner.
- However , if you imagine an exchange of a for b, then the point c is very interesting, almost problem-like, because it can connect to either d or e (there are several problems like that in the literatur), if black had not a weakness at f anyway and there would be a second eye around e.
- Hence, White wants to make a move in that corner for a more important rason, white has his eyes set on the black h16 group (because the white center group has a dead shape).
- Can white find a sequence wich - prima facie - kills hat group?
- If Black obviously resists - what could happen next?
- What different results could these "next" be?
(after the solution for a killing sequence one will discover the further implications)
