Hi, here's something that happened in my last game, where I was playing black :
$$Wc
$$ ------------+
$$ O . . . . . |
$$ O . X . . . |
$$ O . X . . . |
$$ . O X . W . |
$$ O . O X . . |
$$ X O O X X X |
$$ O O X X O O |
$$ X O X O . O |
$$ O . O O O O |

[go]$$Wc
$$ ------------+
$$ O . . . . . |
$$ O . X . . . |
$$ O . X . . . |
$$ . O X . W . |
$$ O . O X . . |
$$ X O O X X X |
$$ O O X X O O |
$$ X O X O . O |
$$ O . O O O O |[/go]
I found this, black lives but white connects :
$$Bc
$$ ------------+
$$ O . 6 . . . |
$$ O . X 4 2 . |
$$ O . X . 3 . |
$$ . O X 1 O 5 |
$$ O . O X 7 . |
$$ X O O X X X |
$$ O O X X O O |
$$ X O X O . O |
$$ O . O O O O |

$$ O . O X 7 . |
$$ X O O X X X |
$$ O O X X O O |
$$ X O X O . O |
$$ O . O O O O |[/go]
Is there anything better for black ?

Is there a stone at S15 or not? The diagrams are conflicting there.

your second dig is differnet from first..
anyway..you can get seki or ko..
depends on ko threat..you may choose this option.

Assuming the first diagram is correct, what about:
$$Bc
$$ ------------+
$$ O . 3 . . . |
$$ O . X . 2 . |
$$ O . X . . . |
$$ . O X 1 O . |
$$ O . O X . . |
$$ X O O X X X |
$$ O O X X O O |
$$ X O X O . O |
$$ O . O O O O |

Your diagrams don't fit together. S15 differs.
Why not 5 at R19? Assuming Diagram 2 is correct

Sorry for the diagram mismatch, S15 is here, but only as the last play. I edited.

Reading calmly, I think black wins the semeai. It looked too dangerous in game.

Hi Lorill
Have you read enough ? because thinking of and beeing sure is quite different
Edit : I think black can get seki at best (white connect his 2 stones and has enough liberties to create a seki). But is there a way for white to kill black... i'm not sure.
