Hi, > The most noticeable case of this is with Mi Yuting's flying dagger joseki. I'm not familiar with this. I found Hirofumi Ohashi 6d pro's explanation half year ago in HCCL ML. The following is a quote. ------------------------------------------------------------- https://gokifu.net/t2.php?s=3591591539793593 It seems that it is called a flying dagger joseki in China. This shape, direct 33 to lower tsuke (black 9th move B6) is researched jointly with humans and AI, but still inconclusive. After kiri (black 15th move E4), mainstream is white A, but depending on the version of KataGo, white B may be recommended. By the way, KataGo I'm using now is 1.3.5, which is just a short time ago. This kind of joseki is not good for Zero type. Ladder and capturing race are intricately combined. In AlphaGo(both version of AlphaGoZero and Master) published self-matches, this joseki is rare. ------------------------------------------------------------- I found this joseki in kata1_b40s575v100 (black) vs LZ_286_e6e2_p400 (white). http://www.yss-aya.com/cgos/viewer.cgi?19x19/SGF/2021/01/22/733340.sgf Mi Yuting wiki has this joseki. https://zh.wikipedia.org/wiki/%E8%8A%88%E6%98%B1%E5%BB%B7 KataGo has special option. https://github.com/lightvector/KataGo/blob/4a79cde56e81209ce4e2fd231b0f2cbee3a8354b/cpp/neuralnet/nneval.cpp#L499 > a very large sampling of positions from a wide range > of human professional games, from say, move 20, and have bots play starting > from these sampled positions, in pairs once with each color. This sounds interesting. I will think about another CGOS that handle this. Thanks, Hiroshi Yamashita
