Life In 19x19

Hello,

[edit]In endgame,[/edit], this seems to be a common move (at least in handicap games). does anybody has a few documentation on this ? is there a sensei page for that situation ?
I think a or b are fine for black, but I would like to study that position a bit more... so any comments welcome !

Hi oca, usually happens much earlier than the endgame.

Hi Edlee,

oh... ok... I'm still a bit confused with what is an endgame move and what is played more early then the endgame... this would be more endgame is it ?

Hi oca, yes, and not only endgame, but aji keshi.

A voice in my head screams clamp clamp clamp, but I can't really find a conscious way to do it

I was thinking that was a good move... mainly because black cannot block at a

So I think that would endup like this which looks not that bad to me...
Does black get too much here ?

Also the peep at 3-3.

Why not ?

Maybe that would endup like that ... (I saw the main line in a book)

Hi oca, yes, B has those options.
But if W does not hane on the first line, W has even more options in the corner.
So if W does the first line hane too early and gets the result in your second diagram in post 7, W fixes all of B's weakness for B, and removes all of W's options in the corner -- thus, aji keshi.

ok thank you Edlee, I will explore the 3-3 invasion in that situation too.

I looked at that, but what about this variation?


I really can't find a satisfying variation for black

As it is, atari on the outside, if W lives, fine, ponnuki on the outside. And I doubt it lives anyway

Thanks, I thought white was alive, so it seemed bad for black, since R4 was played with the intention of getting some points in the corner.
