White creates a ko
Scartol: I'm surprised no one has responded to this yet. I believe this is correct; black has to play in order to make two eye shapes; the throw-in at
then starts the ko. Black has the advantage, since he can immediately capture, forcing white to find the first threat.
If white tries to play on the top first, black will just extend and make two eyes (white can't push at A or black will immediately capture).
Isn't that a false eye?
Rich - No, because 3 is an illegal move - it's already totally surrounded, and it doesn't capture any stones. White has a ko threat at 'a', and otherwise black is absolutely uncapturable..
