Beginner Exercise 56 / Solution

Sub-page of BeginnerExercise56
Main line  

The descent at B1 is key for life. If W2 makes a placement, then B3 and B5 forms a seki. This is the main line.

// Isn't B5 unnecessary? -Heikki

JoelR: It is necessary. If White gets W5 and the point to the left of B3, Black's left side is in atari.


If W2 plays the hane, then B3 divides the eye space into two eyes very nicely. White cannot cut at a because of shortage of liberties.

Black's failure 1  

Descent on the wrong side. The points a and b are miai for the kill.

Black's failure 2  

B1 doesn't live. White kills with W2 and W4. Black can capture W2 by playing at circle but this only creates a false eye.

Black's failure 3  

B1 is a greedy move that fails. W2 followed by the throw-in at W4 reduces Black to only one eye.

What about this? Failure.  

I thought maybe I had seen something when I started to run these through, but soon answered my own question. B1 is no good either.
