White pushes at the upper edge.

:
Black has to give atari at the upper edge.

:
White occupies a liberty of Black's cut-off stones.

She could have connected at at the left edge as well, not affecting the final outcome of the game.

:
Black captures.

:
White recaptures.

:
Black gives atari again.

:
Now, White connects at the left edge.

:
Black starts the ko fight in the upper left corner.

Ko:

:
White utilises her connection at the top as a ko threat.

:
Black has to capture White's single stone in the right center, in order to avoid me-ari-me-nashi in the Central Semeai.

:
Black gives atari at the upper string of White's left-hand group.

:
White captures the nakade.

Immediately capturing the hanezeki's tail, instead, would lose two points unnecessarily.

:
Black throws-in at the left edge, giving atari at White's stones above.

:
White has to capture the hanezeki's tail just now.

If she mistakenly answered Black's ko threat by capturing with at the left edge, she would lose the ko fight in the upper left corner, and the game as well.

:
Black recaptures.

With the exception of some initial moves, we have reached a change in the order of moves with the previous subvariation.
In comparison, Black captured an additional White stone in the upper left corner, but lost one point of territory in return, so the net effect is zero.

Please refer to an earlier subvariation ( 222cw) for details of the succeeding endgame.

White will win the game by six points.
