White captures first

[Diagram]

Even worse for Black


Author: Confused


Hikaru79:

[Diagram]

Why not White 1?

Does W1 not also work? It forms a good empty triangle with enough liberties to kill the three stones. Here are the variations I've come up with:

[Diagram]

White to win the capturing race.

If B1, then W2 kills. If black tries B1 at W2, then W2 at B1 and all is good.

[Diagram]

White to win the capturing race.

If black plays B1 directly, then W2 creates a shortage of liberties.

I guess I am missing something... can anyone say what? ^^;

Oh, never mind. I figured out my oversight.

[Diagram]

White fails to win the capturing race.

If B1 plays on the edge like so, there is not much white can do about it. I've found my mistake ^^; If you feel you should delete my above attempts, feel free. But maybe these should remain here at the end as an example of a move that DOESN'T work :P

NEW EDIT:

[Diagram]

Perhaps this works?

Actually, after more consideration, this DOES work, assuming there is no black stone interfering on the first or second line until you have enough space and/or liberties for a geta. Once the stones reach there, it is obvious what happens next.

So is this an alternate, although not-as-good solution? Or am I STILL missing something?

Failure for White

JoelR: This atari seems to close this line off.

Hikaru79: Oh wow... how totally obvious ^__^;; Yup, I see. Sorry about that, it was stupid, even for me :P


HolIgor: A little bit more advanced.

[Diagram]

White captures first

White 6pt + 1pt sente yose = 7 pt

[Diagram]

Black captures first

Black 7pt + 1pt sente yose = 8pt

Altogether it is 7.5 points miai. This is the size of a monkey jump.

White is rather secure in the corner. Black is rather secure on the side. Capturing the stones in gote in fuseki or midgame is rather small. This is just a big yose move.

A little bit more advanced yet

[Diagram]

A correct shapy move for black

Take the vital point immediately instead of descending to the edge.
