The kikashi of Michael Redmond in the bamboo joint is a very interesting move that provides White with a difficult choice (and Black thereafter).

:
We will display White's options in the chronological order of our investigations.

@ :
White's atari is the "usual" answer to Black's kikashi, gaining some profit in exchange for loosing a move in the Main Semeai (= this line).

@ : ( 738b)
White's solid connection does not lose a liberty in the Main Semeai.
But quite surprisingly, both moves mentioned above do not work successfully for White, so she has to also consider playing elsewhere.

@ : ( 738c)
The tsuke of Yamada Shinji, in the main line of the Professional Solution gaining two points for White (compared with the "classical" atari at ), will neither lead to success.

@ : ( 738d)
This atari in the upper left corner starts the "classical" endgame and will result in a quite difficult choice for Black. However, White has no valid options for keeping Black from winning the game.

:
White's atari in the upper right loses one move in the Main Semeai, as it does not occupy any liberty of Black's large group.

:
This enables Black to play this large endgame move, successfully defending his territory in the upper left corner.

:
In order to simplify the presentation, we display only the endgame moves in the left half of the board.
Please note that – due to the initial defense of his upper left corner – Black will be unable to connect any of his hasami-tsuke stones . These will become both captured by White during the mutual occupation of opponent's liberties in the Main Semeai.

///:

The comparison of the final positions in the left half of the board (Professional Solution at the left) shows:

• White did neither capture Black's single stone at the top, nor his stone at the bottom, so losing four points ().
• At the upper edge, White lost one point of territory ().
• In the upper left corner, Black gained two points of territory ().

The comparison of the final positions in the right half of the board (Professional Solution at the left) shows:

• White captured Black's two hasami-tsuke stones, so gaining three points of territory () at the upper edge.
• White got one additional point of territory in the centre ().

In total, Black is three points better than in the main line of the Professional Solution.

Black wins by three points.
