During the sequence that creates the hanezeki in the lower right corner, after all of the partial groups have been cut off from each other, there are several moves that deserve attention, and explanation. We did not find sufficient commentaries in the professional sources, so we tried on our own to better understand this very special, and strange, formation.

First of all, there is Black's classical move at . Please note that Black - in the professional solutions - has not played immediately the cut at instead, which would enable him to build an eye in this area, so gaining quick life for his large group in the upper right.

Next comes Black's first throw-in at , not commented in the professional sources, but badly needed - at least in the classical solution - to spoil White's shape, and to reduce the liberties of her group above by one.

Black's second throw-in at , condemned by Fujisawa Hideyuki ([LIT. 2; page 43]; he played this move at , instead), in the eyes of other professionals an unnecessary early loss of one point, remained an amateurish idea of mine until the publication of Cheng ([LIT. 5; page 375]) in 2010. This move does not affect the outcome of the final semeai, but gives Black a small territorial advantage, thus making it the technically correct move. The second throw-in was also confirmed by Professor Prof. Jeong SooHyun in 2011.

Finally, there is the forcing exchange of , , which is unnecessary, and just losing a ko-threat after the second throw-in. However, it must be played (as , ) in the classical professional solutions, again not affecting the final semeai, but preventing a small territorial loss for Black, thus making it technically correct there.
