@posetcay: I tested it with 3 different Katago models and none suggested that move to be significantly worse. Here is AI sensei as an example with 10.000 readouts: https://bit.ly/4gcdST9 As AI is prone to changing its opinion after finding another 10.000 or even 100.000 readouts, I dont think its fair to call M15 a bad move by any means.

C and A are both -0.1 moves for black. C is a very strong move, as it is also sente against whites group on the side. They should both be correct.
