But, not playing the first throw-in does change the outcome! Here Black first forces twice with , and .

Please note that the above statement is true for the classical line of play only. There is no effect with the guzumi.

Please also note that the lower connection of , shown here, is not possible with Joachim's Ko-Semeai.

White needs one move to capture Black's upper right group. But she also takes a liberty of her own group with this move. White may be hindered to take this liberty, which turns every potential approach-move liberty of Black in the top right corner into a real one.

On the other hand, White can also enforce here (, , ) - at the cost of the loss of two of her liberties - that Black himself takes a liberty of his own top right group.

Black needs four moves to capture White's group. Playing the upper throw-in later does not profit Black. Indeed, he needed just three moves to capture White's group in the seki thereafter, but has lost an additional liberty of his group in the top right.
Relevant for the semeai is a "distance" of three moves (four for Black vs. one for White). This means that Black's group in the upper right now needs one more liberty than before with throw-in. This will minimize his potential to answer White's actions in the corner. For the professional solution, this has been shown with the variations for - ( 77).
To some extent, this is also true in our solution, despite the fact that - due to the guzumi - Black's upper right group has got an additional approach-move liberty. It is not really decisive in the very end, but this additional approach-move liberty is usually used to connect Black's hasami-tsuke in the upper right corner. This will not be possible here, so White will gain a territorial advantage of four points (by capturing the pivotal hasami-tsuke stone), reducing the margin of Black's win to one point only.

But, it is not correct with the classical variations to connect at the upper cutting point with now. Also, the throw-in with is necessary in the classical variations only, in which the guzumi is not played later.

This implies that it is mandatory for Black to return to the single throw-in.

White needs one move to capture Black's group.

Black needs three moves to capture White's group.

So the "distance", relevant for the semeai, has been reduced by one to two moves (three for Black vs. one for White).

If Black plays the guzumi (similar to our solution), the semeai in the top right remains unaffected, so White could have connected at the upper cutting point at , instead of at the lower one at , to get the same final results. Black wins both the Capture Variation, and the Semeai Variation, by three points. In the further course of the sequences, White will also occupy the second cutting point (), so this is simply a matter of a change in the order of moves here.
