In a series devoted to seeking the weak points of bots, Ohashi Hirofumi pointed out a mistake with Black 177 in the position below (White has just played the triangled stone).
This was a Golaxy self-play game where it is being trained on various komis, 6.5 here. Black played A and lost the game (after 304 moves) by half a point. Ohashi said (without explanation) that if Black had played B it would have won.
As you can see, the game has already been pretty wild, it's only halfway through and it got even wilder, with a huge trade. I don't think I've ever seen a wilder game, in fact. Yet Ohashi was pretty matter of fact about claiming that was a mistake, and he just added that this version of Golaxy mustn't have been perfected yet.
This was Part 3 of the series, with more to come, so you can infer the pros have found other alleged weak points, too. Ohashi covers Lizzie, Elf and Golaxy.
Without trying to read it out, that situation seems to me to be possibly going to end as a seki (both w and b get an eye) but playing A might, in some way, allow white to initiate a ko to avoid connecting, while playing B will force white to connect, costing one point.
