After the wandering of the Hanezeki's Tail through the centre of the board ( / ), the Crosscut Sequence ( / ), and some initial moves of the Nakade Sequence (, Black plays the placement at in the upper right corner.

:
White's block separates Black's intruder from his allies below.

:
So Black starts connecting to the left along the upper edge.

:
Finally, White has to connect.

:
Black initiates the Guzumi Exchange.

:
The Main Semeai continues, taking a well known path.

And soon and so forth ...

:
White does not connect the Atari at her two single stones below the Nakade.

:
Black starts a Ko in the left centre, but which he will be unable to win.

:
White re-captures the Ko.
For the sake of simplicity, we will let White connect the Ko much later.

It does not make sense for Black to fight a Ko here, as White can use her moves in the Main Semeai as Ko-treats.

:
The Main Semeai continues.

:
Black lets White capture his three stones at the upper edge.

:
White captures now.

:
White connects the Ko in the left centre.

:
Black creates a Ko-shape at the right edge.

This shape is a bit tricky, so White must be on her guard. The order of moves matters here !

:
White chooses the Capture Variation.

:
Black re-captures.

:
White plays Joachim's Oki in the Hanezeki.

:
The time has come to capture the Ko at the right edge.
White must do so latest now !

:
For the sake of simplicity, Black does not start a Ko-fight here.

He would lose this fight anyway, as both sides have an identical number of Ko-threats (Black: to / White: to ).

White wins the game by 3 points (Komi = 1) !
