It seems to us that - as long as the Crosscut Sequence in the upper left centre is not yet completed - White will be unable to win on territory (i.e. without resorting to a ko), even if Black does not follow the course of our solution. In the end of 2014, Joachim brought a long-forgotten idea back into our consciousness.
We will use a sub-variation of Joachim's Ko-Semeai as an example for our explanations ( 270); the principle shown should also be applicable for playing the guzumi slightly later than "usual"). Herein, Black started the Crosscut Sequence without having played the guzumi of beforehand, and then played the hiki of , instead of closing his upper left corner. We have reached the position, where White's group on the upper edge securely lives, and Black's large group in the upper right has the option of getting a second eye for life.

Black's only chance to win is to save his nakade stones on the left edge.

White is in a dilemma now. With Black's nakade, White has not only lost a lot of prisoners, but also a lot of internal liberties of her group on the left side that is not alive yet. This means that White is unable to follow the course of our solution by initiating the Main Semeai between Black's large group in the upper right, and her group on the left side. White would be forced to capture the hanezeki's tail "early", so losing the game decisively.

Thus, White must live on the left with , letting Black also live on the right. The hanezeki in the lower right will remain stable.

Let us now compare the result here with the Capture Variation of our solution, wherein Black's group in the upper right also lives.

White did not lose the 26 points that are associated with the dissolution of the hanezeki, after capturing the hanezeki's tail with a move at .

On the other hand, White did not get the 19 prisoners that are associated with Black filling-in the nakade on the left side. Additionally, Black gained five points by capturing White's three stones in the lower left.

In the upper right, Black now lives independently, with about six points of territory (2 * , 2 * ).

White will not get another approximately six points (, 4 * ) while occupying the liberties of Black's large group.
This means that - only considering the areas discussed so far - White is about ten points worse off than in the Capture Variation of our solution, adding to a total lead of 15 points for Black.

The only area remaining for achieving compensation for White is the upper left corner. Reducing this corner by about 15 points means at least capturing a large part of Black's groups there, it not even killing the entire corner. This aim is not achievable here, so White will clearly lose the game on territory.
