Hrewsahgs: [current position] I don't understand why this variation is considered a mistake. J2 still gets captured after K1 atari.
caranthir: It's not that your move order isn't working at all, but: Opponent's strongest answer to D2 would be D3. Then they would ignore the K1 atari and sacrifice the four stones, living with the rest. D2D3 would end up being a bad exchange. ------- I believe the authors of Xuanxuan Qijing (or those providing the "canonical" answers to the problems) considered this minute aspect, relevant to the scenario where the opponent decides not to commit total suicide.
