Beginner Exercise 19 Solution
Difficulty: Beginner
Keywords: Problem
KarlKnechtel: The eye at a is already secured. White needs to make one in the space around b.
First, White chases Black around. With any other black response, White makes a sagari at any time to seal off the second eye.
White 5 threatens capture of more than enough eye space, so Black must capture.
White 7 threatens to capture again so Black fills in, but it's a connect-and-die - White 9 finishes the job since Black can't escape.
splice: Small technicality. Karl's comment: "White 5 threatens capture of more than enough EyeSpace[...]". As far as I can read, anything less will leave White with one eye. To wit...
So playing until the black stone is hit is not more than enough eye space, it's actually just enough. At least, the way I see it :)
unkx80: In the diagram entitled "Not enough", White 3 is wrong, but Black 4 is also wrong. White 5 lives. aigo: Following the same line of logic, White 7 is another mistake, it should go where 8 is to make an eye instead of capturing the black stone. unkx80: Yes.
Black 4 should be played here. Subsequently, if White a, Black throws in at 2 and the eye becomes false.
This way White has just enough space to make a second eye.
