White pushes into Black's corner.

:
Black closes his corner.

Black does not have the time to give atari with or to descend to , instead, which both would result in the capture of White's stones in the corner.
He would be forced to really take White's stones off the board, therewith losing too many tempi in the Main Semeai.

:
White's hane into the corner aims at starting a ko fight.

:
Black captures the ko.

: (B 222fe ;  C 222ff)
White is ready to capture the hanezeki's tail, and so captures the nakade, hoping to use her moves in the nadade as ko threats here.

However, as Joachim discovered when analysing Black's later subvariation below, this strategy - often useful elsewhere - is not applicable here.
Black would ignore White's threat and capture her stones in the upper left corner, so ending the ko fight. Thereafter, he would win the semeai either with White's group in the centre or with her group at the left. Therefore, White would be forced to capture the hanezeki's tail anyway later in the game, providing Black with a comfortable win.

The same applies for White's ko threats in the left centre, which threaten to capture some Black stones there, in order to secure independent life for White's left-hand group.

There is only one option left for White for winning the game: She has to capture the hanezeki's tail just now, as her very first ko threat.

Black answers White's ko threat in the nakade.

However, as mentioned above, Black could do much better by ignoring White's very first ko threat.

:
Black, in return, uses his kikashi in the hanezeki as ko threats.

:
However, White's forced reply occupies an important liberty of Black's large group at the right, erasing his ability to win a semeai with White's group in the centre.

:
Black gives atari at the 1-1-point.

Simply descending to , instead, would lose this additional ko threat.

Black might consider pushing to at the top. This move would revert to the superordinate variation, after the sequence from to .

Ko: ; ; ;

:
White plays her last ko threat in the nakade.

:
Black is unable to use his push at the top as a ko threat, but he can still benefit by it, as it is sente.

Ko: ;

:
White threatens to capture Black's two stones in the left centre.

Black answers White's ko threat locally.

Playing at , instead, will have a comparable effect.

However, Black must not let White live at the left, as he will be unable to win the semeai with White's centre group.

:
Black's throw-in the centre threatens to capture White's single stone above immediately.

Alternatively, Black might consider playing the peep of , instead. White will answer locally, with .

Ending the ko fight by capturing with will not benefit White. She will lose a few points overall after Black's atari with . just because she will have to dissolve the hanezeki.

:
Black threatens in the upper right corner.

Please note that this is Black's only ko threat at the right side of the board that is not related to the (surrounding positions of) the hanezeki.

:
White terminates the ko by capturing Black's stones, as she is unable to answer Black's previous ko threat.

:
Black captures some White stones in the upper right.

:
It follows an amateurish idea of the ensuing endgame.

We are sure that ...

White will win the game by more than 15 points.
