Beginner Exercise 166 / Solution

B3, B5 take away potential eye  
Coup de grace  



VanEvery - Shouldn't Black play B3 at B5 instead? Since the status is settled after W4, it seems a complete waste to put a third move into this. What is the value of B3 where it is?

unkx80: Do you understand seki?

Cabbage?: unkx80's reply is kind of unhelpful here. To answer VanEvery's question, if black plays B3 at B5 then white plays W4 at B3 and makes two eyes. B3 is therefore best where it is.

Dieter: This is a failure diagram. It serves to show that Black does not kill White this way but achieves at most seki. Discussing the merits of B3 and B5 is irrelevant for this problem, since B1 was wrong to start with and B3-B5 are merely the functional follow-up to the mistake B1 was.
