Mistake - Black loses
Note that for Black to connect at
leads to a hideous loss, because of a shortage of liberties. (Yes, I assumed this was the answer until I gave it more thought.) -- Bignose
What about this elegant move (
)? White can't break in.
Kris: I think there is a move worth one more point - but of course, Black wins in either case.

Lucky
Lucky: Black can play any of the marked points a-g with the same result. If White captures three stones...
... after
Black can connect. Black wins by 7 points.

Ko
White takes ko and has more threats (see HolIgor sequence). So White connects the ko and Black wins by 6 points. Black has lost a point.

Shouldn't this be the next move?

White response
Playing
here is the same as connecting at
in the initial diagram. White could play
, capturing the four black stones. If Black responds with
,
captures all seven stones.
