StephaneLamy: 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.
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.
