I was lucky to find 17.H15. I probably should have played on the left sooner.

Black's sequence leading to 16.o16 was very clever. but instead of getting drawn into that local battle, maybe it would have been better to play earlier in the bottom half of the board. For example,
|8.q17 would have made new threats on the bottom and would have made the threat of black R9 even stronger.

上のコメントの繰り返しです。

17.H15を見つけられてラッキーでした。もっと早く左に打つべきだったかもしれません。

16.o16につながる黒のシークエンスはとても巧妙でした。しかし、そのようなローカルな戦いに巻き込まれるのではなく、もっと早くボードの下半分でプレイしたほうがよかったのかもしれません。例えば
|8.q17は、下に新たな脅威をもたらし、黒のR9の脅威をさらに強めることになったでしょう。

|22.j15 23.j16 24.i13 25.g12 26.f12 27.i11 28.g14 29.k14 30.j13
こっちから突破できたのではないでしょうか

|22.j15 23.j16 24.i13 25.i12 26.h11 27.h10 28.g9 29.k14 30.j13 31.l13 32.l14 33.j14 34.k13 35.n14 36.k16
これだと難しくなりますが大丈夫そうに見えます

I missed |22.i13 23.i12 24.j15
Thanks to ゆう for pointing this out!
So Black was winning after all I suppose.

こっちに受けられる手があってやっぱりダメでした

それはふつうに
|22.j15 23.f16 24.h14
でも大丈夫なのでは?

After |22.j15 23.j16 24.i13 25.i12 then 26.g12 gives black more room.
Then if 27.k14 28.j13 29.j14 30.i11 is much easier for black.

So yes, |22.j15 also wins for black.

真っ直ぐ行くとこれで黒はうまくいかない気がします

本当ですね。

でも、|22.j15 23.f14 ?

例えば、 24.h16 25.d19 26.e19 27.f20 28.d17 29.e16 30.e15 31.e18 32.f18 33.g17 34.h17 35.k15

この図は勘違いしていました。普通に黒のシチョウが良かったです。

|22.j15 23.f14 24.h16 25.d19 26.i9 27.k9 28.i13 29.h11 30.d15 How about this? どうでしょうか?

Another branch is
|22.j15 23.f14 24.h16 25.d19 26.i9 27.h10 28.j7 29.l10 30.o6 31.m8 32.l6 33.n11 34.s4 35.o4 36.n4 37.q5 38.p3

は引き分けを避けることができます。そう、このバリエーションでは、23.f16よりも23.f14のほうが面白そうなのだ。

が、黒にとっては22.i13 23.i12 24.j15の方がはるかにシンプルだったことを念頭に置くべきだろう。
