Endgame Problem 9 / Solution

Sub-page of EndgameProblem9

The informal analysis

[Diagram]
Solution  

W1 is the solution, not a.

[Diagram]
Solution  

What is so painful for Black is that W5 is practically a sente move during the endgame phase. After B6, then White can tenuki, so White has reduced Black's territory in sente.

[Diagram]
Variation  

B2 does not work either. Black loses even more this way.

[Diagram]
Failure  

W1 is considered a failure in this problem. After B4, if White saves the two stones at a, then it is gote. Nothing more than an itch for Black.



The more formal analysis

[Diagram]
Almost sente  

Bill: W1 - W3 is fairly large, about 8.7 points.

[Diagram]
Large gote  

W10 connects at black+circle.

B1 is almost as large, about 8.4 (8.5 points when White is komaster). So White will often be able to play here with sente.

Later B5 - W6 is sente, and even later B9 - W10 is sente.
