My program found another odd alternative. On 118, rather than make the seki at b1, black can play G8, b2, g7, f7, g9, f9, h7. It looks like this makes the upper right a semeai with a ko, and black has a ko threat at b1, and white has no ko threats. For example, continue with j7, j8, h9, j6, j5, d9, j7, b1, a1, j6, any white move, g6
The semeai is complex enough that I can't tell if this is correct, but the program reads it this way. To avoid this fight, white must answer g8, then black plays b1 to make the seki.
