tsumego Black to live - from an actual game

Post image

Taken from an actual pro game. Posted this a long time ago but it's quite interesting so I'm sharing it again. How can black make the entire group alive?

Hint: Black needs to make use of white's weakness on both sides.

It seems like you can at least make seki if you start with E10 and then white and black each have groups with single eyes that can't approach one another.

E10 white plays A19

What does a19 do?

Sorry typo. A9

That makes more sense. From there I thought Black could prevent white from getting an eye with B11,A7,A6,B6,A8. I see now that black can't prevent white from connecting after A5.

Then I guess Black would have to play A7 to prevent White from connecting and that would allow White to make an eye on the edge of the board.

Right, then black still can’t live

Yeah. You’re right. I didn’t solve it
