This is a game, I believe, from the 54th NHK cup (I have kifu saying it was in March, another in April). Someone posted it in reddit and it pinged my interest.
I was checking it on my mobile with Ah Q Go (sorry; my GPU died and I haven't gotten around to configuring Leela on CPU-only mode), and there are some things that pike my interest.
* The robot doesn't seem to register MV 271 as a blunder. It does register MV 272 as a winning move in the graph, but neither is in Ah Q's list of blunders or tesuji.
It's not that I need either in this particular case, but it looks like I'm missing something, there. On the workings of the program, at the very least.
But, also, there's some L&D I'm not sure about. Before the blunder...
All five lower groups are alive. I mean, there might be an option to kill the group at O1..O5 in exchange for something. Maybe. But I wouldn't count on it. I most certainly wouldn't be able to.
The inverted T at K4 is dead, a single stone from capture. That makes the while center White, alive.
Top right white seems very much alive to me, too. I don't see a way to kill it that is not all smoke and mirrors.
The one I'm not sure is White's centre-right group at M7..S7. I see it dead (I see no way to turn that twisted-4 into two eyes), but I'm not sure if there wouldn't be a way to win the race with the group at Black's "H" at R11..T13 and its left wormish cousin.
It looks like there are a lot of ifs for a game supposedly well in Black's favor... before that move.
Am I missing something or is it "just" that Leela's already read that rightmost fight and considers it in Black's favor?
Thank you. Take care
