: (96 222ac) It is much too late to play the guzumi, instead. : (99 222ae ; A 222ag) White might consider continuing with the "classical" hane at . She will still be one point better than in Our Solution, but nevertheless fail to achieve the optimal score of the subvariation below. The same is true for White's wedge at , which KataGo (2020) favours over the "classical" hane. White's score in the Semeai Variation will benefit by five points, because she takes more profit (for the Capture Variation) outside the Main Semeai area than after the hane. : : As usual, there is no need to choose the solid connection of here, in order to keep Black par with the Punishment Semeai Liberty Level. White would lose points unnecessarily. : : : Defending his lower left corner, with a move at , instead, is out of the question. Black would fall prey to the Punishment Semeai. ; : | |
: (A 222ah ; 114 222ai) The other one starts the endgame at the left side of the board with in the lower left corner. However, I found out that none of these two moves is correct, as White's unimpressive, and silent, move of at the top will achieve a final score that is one point better overall. For a reason that I do not understand, KataGo (2020) seemed to have overlooked this move, which erases White's weakness at the top, and also lurks into Black's corner. : ( B 222am) It is very likely that this experience was due to my weak hardware, as KataGo (2020) also favoured the correct move at not before a very large number of playouts for this position. | |
