Ko fight example from a pro game - 7
unkx80: The following game between Takagi Shoichi (Black) and Lin Haifeng (White) may be an example. There is no commentary regarding the ko.
unkx80:
cannot play at
, or it will result in White a, Black b, White
, resulting in a capturing race that Black cannot win.
unkx80: I guess that the aim of starting this ko is to get both
and
for compensation.
unkx80: After the White cut, Black's framework at the bottom vanished in no time.
is needed to settle the large dragon.
Dieter: As a minor remark, I believe responding to
is much better than
.
Dieter: In order to understand the strategic concept, we must evaluate what happens if White does not use the ko. Suppose White kills locally, then
leaves bad aji, because a now is sente (small reading exercise). Or will
be played at b?
So I think part of the purpose of the ko was to eliminate the bad aji at the top, by forcing Black to play the threat at
(two diagrams ago).
unkx80: I don't claim to fully understand this game, but I suspect
will be played at b. Then when White cuts at
, Black may give up the two stones.
Dieter: I understand the reasoning, but doesn't a clean capture of the upper left, as would happen if Black gives up the 2 stones, simplify the game even more?
