This situation happened to me on a 19x19 board. I (Black) played on H7 to secure the group, but the AI review showed a decline of 43 percent in my winning rate after this move. I don’t know if it’s because it thought the group was already alive, or because it thought I can gain more profit elsewhere.
So: What is Black’s status here, if it’s White’s turn?
Hi,
As far as I can see :
Ok, so black must protect with another play at H7, but why did the AI think that this was a terrible move?
@Zuko_1, can you share a link to the actual game? I think it’s impossible understand the evaluation of the AI without the bigger picture.
It’s move 171
So it’s quite clear from the big zig zags in the graph that the AI thinks the fight in the centre is the most important thing right now. It’s worth giving up the corner to seal the kill on white’s centre group.
Yeah I guessed that was the logic behind it
Yeah, at that point the whole White center is pretty sketchy and about to die. Attacking it should certainly be sente and if sucessfull is way bigger than the corner even if it did die.
