unkx80: This is the solution.
There is death in the hane. Black reduces White's eyespace twice, and then makes the nakade (placement) inside, reducing White to one eye. It doesn't matter that
unkx80: Sorry but I did not notice the mistake in your description earlier. Your description suggested that Even running away at the first hane won't work:
Black has to be careful not to let White escape or make a second eye near the corner here. At this point, c is answered by a, and otherwise the pairs a and b, d and e, and f and g are all miai; Black kills. The instant that White seals off a 1x3 space (which Black will force with this line of play), Black must play at the middle of it. Even if Black leaves two stones in atari in the left side as a result, White cannot live:
Jasonred- There's no ko in this case, so wouldn't this be the time to play

One more way to resist, you say, since White still has liberties and a cutting point? Now White is too close to the corner. Things get even tricker here:
Now I think unkx80 has a point about protecting the cut first. Looks like I'm a victim of concurrent editing. ^^; unkx80: Of course protecting the cut first is better. What if I add a white stone in the problem at the 2-2 point?
So I'm feeling a bit dumb here. My natural affinity for symmetry had me consider this position first. I don't see the flaw. OK, after a lot of thought, I see the flaw. Immediate reply is here:
At this point White will get two eyes directly, or a four-point long eye which lives. Black d gives White a, trading b for c or vice versa. Black a, b, or c gives White d, which collapses to a four-point space - alive. -JoshuaRodman? Dieter: If Black b, White is more likely to answer at a, because this gives life with eyes and points. White d Black a gives a seki: no points. unkx80: If Black b then White can also play tenuki.
Didn't see this right away, until I started diagraming it as a possible solution. Ends with 2 eyes for white. Coyotebd
David Diamondstone: Actually,
With a and b miai for life, as explained by JoshuaRodman? above. This is a copy of the living page "Beginner Exercise 11 / Discussion" at Sensei's Library. ![]() |
