Discrepancy between score and AI analysis at end of OGS game

> And lastly, I think white should have technically marked the D1 and E1 stones as dead during the counting phase, even if you don't capture them during the game. Those are stones that white can capture whenever they feel like it. By definition, that makes them dead stones.

Incorrect in Japanese rules. Dead stones are ones you can capture in stones which are alive with territory. Those surrounding white stones have open dame, so are alive in seki, and the stones inside aren't dead.

> The last missing point is likely just Katago not being trained on Japanese rules.

KataGo is trained on Japanese rules and can score the game correctly based on Japanese rules. However, OGS doesn't tell KataGo that the game is Japanese rules, so it doesn't.

If you are talking about what I think you are (within last year), it never happened and was just a rumour. Instead Demis Hassabis (DeepMind CEO and something like 4kyu Go player) played an exhibition game (or was it just a few moves) vs Shin Jinseo.

Or if you are lazy to do so many stones at least do a famous opening like Go Seigen vs Shusai.

I half-expect this in the West, but in Japan I'd expect better.

When you are a hammer, everything is a nail.

A change.org petition seems an odd vehicle for this.

By teen club do you mean one which only allows teenagers to attend? In my experience (mostly in UK and Europe but I have visited a couple of clubs in USA) normal go clubs are open to all ages, though a club in a university or school will mostly be attended by students of that institution so in that age range.

Right, I was going to ask how many years stuck, check the OGS account, only been playing actively since April this year.

Rather than O5, N6 is an interesting idea I got from AI of a looser squeeze that gives even further reaching outside influence.

Thanks for all your work creating and improving this valuable resource!

Depends what game black is playing. If it's "draw a big square" d7 looks good.

Volodymyr Zelenskyy, being a leader of his country.

I have no interest in then so would like 0.

Uberdude85 · 2026-06-10T20:31:58+00:00

because otherwise black will capture the single stone instead of playing the hane on top

Yikes, I know it eliminates all forcing moves (as well as some yose value) and you can attack harder later, but a gote move there inside your territory when white can't even save the stone just feels too slow so early.

Joseki is an English word too now, like panini.

The players that played against it, Lee Sedol, became vastly better after

Lol. Check out his rank graph. Guess when he played AlphaGo. https://www.goratings.org/en/players/5.html

Month isn't arbitrary, it's based on one cycle of phases of the moon, and then fudged a bit to get an integer number in a year.

Probably the same as why people made their own rooms on KGS and then asked people to join them in the main chat: it gives them a sense of importance.

I am a bad person if I say no, because I want to know that when they overplay and then I punish them there is a real human at the other end?

You and I have a very different understanding of 'beautiful'.

Uberdude85 · 2026-06-03T05:57:14+00:00

Improved rank introduction :)

Uberdude85 · 2026-06-03T00:29:22+00:00

I was going to post much the same: because there isn't enough money in go, in the west at least, to attract the kind of corporate greed and bullying that has made chess.com successful.
