Black must connect. Otherwise white captures two separate stones and makes two eyes.
But after black connects, white can capture the whole group and has miai: C19 or G19 to make two eyes…
sometimes my ranking of the puzzles I entered is inadequate. If you encounter such puzzles, please let me know. When ranking I often feel like a blind man in a dark room.
if you find an interesting puzzle collection on OGS, let me know so that I can offer puzzles from it in this thread.
You can also put those puzzles in this thread. I don’t mind if other players add puzzles.
Do you have solutions for Shusai’s puzzles?
Do they give some motivation for moves?
Sometimes I see something I don’t understand and wish there could be author’s thoughts about that.
Anyway any suggestions or explanation are welcome.

After first move we can understand that the goal is to save A18 stone and reduce or take the corner.
Actually white’s shape on the side is a bulky five which may be killed, so at first I thought that was the goal.
Anyway if black can’t save A18 he can’t think about killing white. So, let’s save A18 first.
It seems to me that white makes some wrong moves.
After black C19 why D18?
From the solution we know that it doesn’t work. But what about B18 or B19?
After white D18 and black E18, white C17 seems quite a odd move. It’s useless (black connects) and takes away a liberty.
While B18 and B19 still seem to work for me.
I then tried to proceed as white, trying to settle the group on the side but I couldn’t find a way.
So actually saving A18 kills everything.
I then realised that capturing A18 and connecting back for white isn’t enough to live: even with A18 captured, black can prevent white from making an eye in the corner.
Is that the reason for white’s attempt to come out instead of capturing?
It’s just too hard for me: even with solution I can’t really understand that puzzle.
I would love to know what the author’s motivations are, but unfortunately the captions in these books are in Japanese. So all we can do is discuss and speculate.
And to be honest I also don’t always understand why some moves are made and others not even considered.
Howdy, let’s start with an endgame puzzle for DDK-players. In the endgame playing moves in the right order is important. Go for the biggest move. And keep the initiative. Black to play.
This (almost identical) twin puzzles phenomenon is something that Shusai did in more cases; adding a stone or maybe two stones and thus creating (totally) new puzzles.
