(A 648ap) Black might consider pre-empting White's following kikashi in the hanezeki by giving atari at , instead. However, he will no longer win the Capture Variation, while not gaining overall (compared to the correct line of play below). : She could play her kikashi in the hanezeki, instead, which is absolute sente. We included this forcing exchange , at the very beginning of the following subvariations for if necessary. : ( D 648ay; E 648bn; F 648br)
However, Black has to play at , instead, closing the hole in the left centre, and simultaneously occupying a liberty of White's group at the left.

: ( A 648cj) Black has sufficient Main Semeai Liberties to spend, so White will not choose Dany's Sacrifice. However, with the knowledge about Joachim's Final Ko in the Semeai Variation, White will now choose Dany's Sacrifice. This will reduce Black's Main Semeai Liberties by two, and so inhibit the application of Joachim's finding. White will play her kikashi in the hanezeki, instead. | |
: ( A 648ck) However, with the knowledge about Joachim's Final Ko in the Semeai Variation, Black will not play this move, but continue with the Main Semeai, instead. White did not want to pre-empt Black's atari by playing her own kikashi , . Unnecessarily, White would lose one point in the Capture Variation, while still being unable to capture Black's large group in the upper right in the Semeai Variation. : | |
