Keima protecting the cutting point

    Keywords: Shape

The keima connection is an efficient shape. It assumes any cutting stone can be captured, typically with a ladder or possibly a loose ladder.

Example

Ladder 1

Ladder 2


[Diagram]

Net?

unkx80: Extra line?

Yes, why not ? ;-) we could also be in the center and not in a corner even if these rectangular shapes are much seen in corners

unkx80: Okay... I added the white+circle stone. These diagrams are a bit confusing for me.

[Diagram]

Safe

Careful, not to put the black+square group in atari.

[Diagram]

Unsafe

[Diagram]

Still safe

Chaz: Capturing via ladder this way instead of via a net works (provided the ladder is good) without Black first playing at X, regardless of how many more lines are between this position and the top of the board.
