Thank you! Yes exactly, there are some outdated diagrams.

Let's have a look and edit where needed.

JosephDye: I can't get an activation email for making a new account (2025-05-16 04:27) [#12586]

I can't get an activation email for making a new account. Is there an email I can contact about this?

xela: Re: Reply to xela (2025-05-16 01:29) [#12585]

Ah, now I see what you were trying to say. In context, it appeared as though the quote was supposed to explain why the pincer is not popular. But actually, you wanted to explain that pressing is now the most common response. Yes, I'm fine with your proposed text in that sense.

However, I think the page needs a more comprehensive revision: there's two other diagrams ear the top of the page with "common replies" and "other replies", and those diagrams are out of date (if they were ever correct in the first place). I might have a closer look on the weekend if I can find some time. And of course you're welcome to keep editing :-) Thanks also for adding the pro game examples.

Hi xela, this time I do not really understand your point.

It is true that the low pincer lost popularity at some point, before AI.

In the age of AI, pincers have generally lost popularity.

However, this particular pincer is still played, with new variations being developed. The pressing move is the most common answer nowadays.

Thus, maybe we can keep the text like this:

In Fuseki Revolution it is said: "Since the advent of AI, the view that a pressing move is always an effective answer to a pincer has been established". That is, in the age of AI, a would be the go-to move.

(where a is the knight's move press in response to the pincer)

xela: Why did *this specific pincer* become less popular? (2025-05-14 02:31) [#12583]

I'm about to delete the following paragraph from the main page:

In Fuseki Revolution, Theme 20 - Why has the pincer lost popularity?, it is said: "Since the advent of AI, the view that a pressing move is always an effective answer to a pincer has been established". That is, in the age of AI, a would be the go-to move.

(where a is the knight's move press in response to the pincer)

As I understand it, this is about pincers in general. It explains why the 2-space high pincer, which was very popular immediately pre-AI, has almost disappeared from pro play, and similarly the 1-space low pincer. But the 2-space low pincer had fallen out of fashion much earlier.

5.58.81.171: art of 9x9 book superhuman edition (2025-05-01 13:08) [#12582]

Guys, could you send me a link to this book or tell me how to properly open it on GitHub? ( It opens, but not all pages load. [ext] https://github.com/9x9go/superhuman ) Usually, pages from part 1 load, but from part 2 and part 3, no pages load. I would really appreciate it."

Shouldn't the second player get a chance to preemptively turn her move into a response to the opponent into the other game?

Jono64a: Re: The KBA site seems to be down for everyone (2025-04-18 20:09) [#12580]

It wasn't just a matter of changing m.baduk to baduk. There were a few other code changes needed, but at least the article number remained the same:

Articles:

Unkx80: Re: The KBA site seems to be down for everyone (2025-04-18 15:14) [#12579]

Although [ext] https://m.baduk.or.kr/ is down, [ext] https://baduk.or.kr/ works perfectly fine. In my mind, the "m" prefix in "m.baduk.or.kr" indicates a version of the site for mobiles, but these days it is possible to create webpages with a responsive design that renders well for both desktops and mobiles, so mobile-specific sites are increasingly becoming redundant. Of course, I agree that they could have done better by redirecting URLs under "m.baduk.or.kr" to the new home.

For some reason, I am not able to do a exact string search on SL using "m.baduk.or.kr", so I have no idea whether a URL that used to use "m.baduk.or.kr" can be mapped to "baduk.or.kr" or something else. Additionally I don't understand any Korean so I don't know how to navigate the KBA site.

Jono64a: Re: The KBA site seems to be down for everyone (2025-04-18 01:19) [#12578]

Looks like they have a new site. Fortunately, for many broken links, there is a simple fix that keeps the old ID number. So copy-pasting the new site URL over the old fixed many KBA broken links all over the site. A responsible website admin would make sure that old links redirect to new ones, to avoid broken links galore on other sites linking to it (and presumably boosting SEO ranking).

Approaching from the other side does not help  

Playing B1 does not help. White answers with W2 and black cannot play at ``a`` because that would be self atari. So black still needs to play at ``b`` allowing white to win the capturing race with ``c``.

23.92.1.151: Is the right answer truly c? (2025-04-14 05:28) [#12576]

Approach moves make a difference  

I simply changed the "a" and "a" for r and u.

If black is playing, r would be the correct solution, not c.

77.14.48.217: Birth date 5 may or 6 june? (2025-04-13 20:01) [#12575]

1st and 2nd paragraph give contradicting dates of birth. John Power's book Invincible says 5 May, Wikipedia says 6 June. Which one is it really?

Jono64a: The KBA site seems to be down for everyone (2025-04-13 19:47) [#12574]

I have found that links to the usual KBA site [ext] https://m.baduk.or.kr/ from here are broken for some time now. So I checked with [ext] https://downforeveryoneorjustme.com/, and sure enough, it was:

“It's not just you! m.baduk.or.kr is down.”

2001:067c:2d50:0000: Hikaru no Go as a chinese series? (2025-04-11 23:40) [#12573]

While searching for episode 76 of Hikaru no Go on Youtube, I stumbled upon a real movie series, apparently from China. They have subtitles, besides Chinese also English. I still didn't watch it, but when you look beginning at position 8:40, it really seems to be the story.

I see; thank you!

222.205.46.129: bug with the website (2025-04-04 02:50) [#12571]

There is something wrong with the website, so "PWD" and "Bin Go Weiqi" are closed for a day. ("PWD" is "bingoweiqi.com" and "Bin Go Weiqi" is "bingoweiqi.com/bingoweiqi2012" so closing "bingoweiqi.com" will close both.) I hope it can recover tomorrow.

Mysteryflight: Re: info about the table (2025-04-03 23:29) [#12570]

You need to know about responsibility games. Those games in the table are the last games before the rank is promoted. For example, the 3rd round of the preliminary tournament of the 2nd Jincheng Professional Weiqi Open Tournament was the last game Qiu Yuran played as a 5p Go player (in group 26), and he rose to 6p after this game, "70" means his average scores reaching 70 (not less than 70 but less than 75), "responsibility game amount" means the amount of the responsibility games whose scores are calculated to get the average scores, and there are 23 responsibility games whose scores are calculated, which he played as a 5p player. Although he needed 24 responsibility games by rights, his average score could have reached 70 even if he had lost the 24th one, and that's why he only needed 23. The total amount of responsibility games can be larger than the amount mentioned above. For example, Qiu Yuran played 29 responsibility games as a 4p Go player. I think there can be a program to calculate the biggest average score when the responsibility game amount needed is guaranteed, but I don't really know its whole operating mechanism.

47.37.21.60: rectangular6 (2025-04-03 15:41) [#12569]

Shouldn't rectangular 6 in the corner get a mention as unsettled?

Malcolm: Re: rectangular6 (2025-04-03 10:47) [#12568]

The text above the table mentions that things are often different in the corner; and there's nothing saying the table is an exhaustive list - even though it does seem to aim to be close to one. So I don't think it's really necessary to add it. (Also, I don't feel this table is particularly useful or easy to read either...)

However if you feel strongly about it then do feel free to add it.
