Black plays an "extra late" guzumi, after the Crosscut Sequence has been completed.

:
White captures the nakade, forcing Black to live in the upper right. It follows an amateurish idea of the endgame.

White wins by two points.

We think that Black cannot successfully play the guzumi, after the Crosscut Sequence has been completed, if White is still able to live independently at the left.
