White can pincer out at B5 or cut at C4 to get E3 sente. It’s better to put more stones outside.

I think there is something wrong with this problem as R5 is wide open and black is alive by playing anywhere since O7 is one eye. Also moves like this do not make any sense:

Well, you may be right, you may be wrong in this. That is something way over my head.
Unfortunately for you the three times Honinbo Utaro Hashimoto is convinced that his solution does make sense.

I’m 99.99% sure the solution doesn’t make sense. I’ve never seen the original problem, but either the problem has an error or the solution has an error.

To start, what will White play when Black pushes at R5?

And why connect at R8 when you can just take the stone at T7?

Life or death

Seems like the answer is not set for this variation?
No moves work and nothing appears with the hint button.

Sorry, the answer was and still is there, but I forgot to mark it as correct (which I just did).
Thanks.
