White connects solidly. This keeps the liberty count stable, as far as the main semeai between Black's large group in the top right, and White's group on the left side, is concerned.
However, counter-intuitively, this will become a lost move in the semeai between Black's large group, and White's group on the upper edge, enabling Black to successfully choose Joachim's Ko-Semeai ( 257).

It will be obvious that Black permits three points of White territory locally, if he does not play the guzumi.

Due to White's solid connection, Black has got the opportunity to do without the guzumi, and to choose a more aggressive option, instead.

The Hanezeki Exchange ( - ) must be played earlier.

Here, White will gain one point by playing an unbelievable tenuki in the hanezeki in order to attack Black's upper left corner with a hane at .

Please refer to 503 for details why our previous order of moves was mistaken.

:
If Black answered with a move at , which is possible due to the additional liberty for his top right group, he would gain one point in the Capture Variation (Black + 6 then), but loose one point in the Semeai Variation (Black + 2 then).

White might choose the Capture Variation, instead, which will end two points worse for her, as known already from our solution.

Black wins by three points.

This is the same result as with our solution.
