Which joseki mistake led to this position…
Suffice to say that White never used any time.
And he didn’t resign for another 180 moves…
bugcat (B) vs 4k
I find (4) questionable, but the bot doesn’t really stamp on White’s WR until (10).
#23 is in the wrong place, isn’t it?
I am quite confused by all these exchanges, so I’ll focus on the most irrelevant detail : what does 19 mean? And why 20???
Nah, that’s the real (23). (19) was a throw-in with the aim of reducing Black’s eyespace, but perhaps it should have been at (20) or just reserved as a ko threat.
Number 23 is on a stone which was already on the board in the previous image.
When 22 pushes, the stone that connects is on the star point, isn’t it?
Ah, yeah. Good catch.
