[Diagram]
White creates a ko

Scartol: I'm surprised no one has responded to this yet. I believe this is correct; black has to play B2 in order to make two eye shapes; the throw-in at W3 then starts the ko. Black has the advantage, since he can immediately capture, forcing white to find the first threat.


[Diagram]
Black's squeamishness punished

If black plays the wimp and tries to run from the ko, he'll just die outright.


[Diagram]
White's misstep

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).


[Diagram]
False eye?

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..
