Beginner Exercise 56 Solution
  Difficulty: Beginner   Keywords: Problem

[Diagram]
Black first to live.

Karl Knechtel: Don't be greedy. The descent seals off enough eye space for Black's two eyes. White's hane won't work here: B3 is all that is needed to divide the space as White can't cut at a (because of shortage of liberties)).

unkx80: So far so good. How does Black respond if W2 is played at B3 instead?

Karl Knechtel: W2 at B3, B3 at W2, W4 at a appears to make seki... and any other B3 response would seem to let White connect underneath. So I suppose this is the main line.

unkx80: Yes. I reproduce the main line below.

Main line

Wont black die if it become like this??


[Diagram]
Black's failure

B1 fails here; it allows White to throw in. Black's eventual eye space will consist of (at most) the marked area, and White can play W4 at the squared point to kill that space (though I don't even think it's necessary immediately).


[Diagram]
Black's failure 2

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