After a long search for a move that gives Black a net gain of at least three points, I found this guzumi. It is, more or less, the only place where it is possible to destroy additional points of White's territory without taking liberties from Black's group in the top right corner. This move also gains one potential approach-move liberty ( 1095) for Black, which will be essential for the hasami-tsuke, discussed next.

If Black lives, then White loses three points () of territory, compared to Fujisawa Hideyuki's Capture Variation.

This effect will be sufficient to give Black victory by one point, even if the missing 71st Black stone is considered to have become an additional White prisoner.
