    C11-D11-B11 also seems to work without exchanging atari, or am I missing something?
    d4rkm4tter:
    There is probably some advantage when the atari is exchanged, but I can't see why it shouldn't work without it. I added it.

    I agree with ZuzuGo: when the main line splits into 3 "corrects" variants F7, F8 or F9 for black, it seems only the solid connection F7 should be correct. In the two others white can atari and make an eye. If we're both missing something, should add a few moves to show the refutation.
    Ivan Detkov:
    Resolved.

    ZuzuGo:
    Are you sure F8 or F9 kills the white group? White can atari on E6 and then make a second eye on E5.
    Ivan Detkov:
    I couldn't follow your comment.
