As we discovered recently (early 2014), White will be able to also win the game with initiating a "fake" Punishment Semeai by capturing the hanezeki's tail.

However, contrary to the main line, White will need support from the top left corner here. Therefore, we do not consider this sub-variation to be technically correct.

:
White gives atari inside Black's eye, so the life of Black's group depends on ko again.

:
White has this winning ko-threat in the upper left corner that Black is unable to answer.

:
White captures the left-hand part of Black's top left corner in sente.

@

:
Now, White captures Black's nakade stones, too.

Black would have been able to save these stones, but sacrificing the entire top left corner would be approximately ten points worse.

White wins by ten points.
