Tsumego From Games 104 / Solution

Sub-page of TsumegoFromGames104

Up to B9, Black lives. B1 sure is a surprising move. It can be found when desperately looking for a way to make B7 sente.

Var at W6  

3 against 2

Var at 2  

This is the strongest resistance by White.


The result is a approach ko for White. (W6 is the approach move.) If Black omits B9 in this diagram, White can simply fill a Black liberty -- no ko.


Black should accept the ko. If B3 here, he is short of liberties.

Var @ 2  

This is another variation where White cannot afford an attempt to kill Black, due to its sudden shortage of liberties, caused by the amazing 1-2 point throw-in.


If Black plays B1 and B3 first, he has removed liberties of his own, allowing White to play W6 in reply to B5. Now Black is short of liberties himself before he can inflict it on White.
