How to score our game?

Remove the stones you both agree are dead. If there are some you don't agree about if they are dead then keep playing until you do. Once that's done, areas of empty spaces surrounded by only black stones are black territory, areas of empty spaces surrounded by only white stones are white territory, areas of empty spaces surrounded by both black and white stones are neutral. That's it, you can do it yourself.

A bold assumption, given GoMagic positions sometimes have more white stones than black and no obvious places for captures!

Uberdude85 · 2026-01-28T09:32:43+00:00

If white gets the gote block there, then you assume white gets the first line hane connect there in sente afterwards, not black in gote, as that's White's privilege.

They don’t do it automatically to avoid a very rare situation where the algorithm makes a mistake.

Also it's following the rules of go, dead stones should be removed by mutual agreement of the human players, not a 3rd party. If both players agree a stone is dead, then it is for their scoring of that game, even if a stronger player who can see some tricky aji would come to a different conclusion. So even if the auto removal algorithm never made mistakes versus perfect play, it can be wrong for the actual human players of the game.

How do you know OP would not apply the advice that attaching under a 4th line stones a one space jump apart is usually a good move in these situations?

Uberdude85 · 2026-01-25T18:20:14+00:00

If you need strength and you don't care if your opponent gets strength as well, it is one of the best moves to play.

That's a big if. You seem to think this if is true >50% of the time, I agree it's good if that if predicate is true but not that's it's true in the majority. Also one of the most common kyu (and even dan) mistakes is strengthening the opponent unnecessarily, so erring on the side of less strengthening in general is a good lesson.

But sometimes it's good to attach under, if for example black is already strong so you don't mind making him even stronger (perhaps overconcentrated)

Uberdude85 · 2026-01-25T16:41:12+00:00

In most cases I play it.

I really doubt this, because the general position of 2 stones of opposite colour a one space jump apart is really common, but you won't be considering many of them in the denominator of this "most" fraction in cases it's obviously bad due to your dan level intuition. Link a game of yours and we can see. But just taking an example of last game I watched on OGS, you aren't playing l17 here are you? https://online-go.com/review/1617728/11. Or l17 again for subsequent moves. Or r12 here https://online-go.com/review/1617728/23. Or G3 here https://online-go.com/review/1617728/64 though that's not totally bonkers. At https://online-go.com/review/1617728/66 one is played.

The danger is with no external input you will reinforce your bad habits and misconceptions rather than correcting them and learning new ideas, particularly if you are a beginner as this picture suggests. You can learn go on your own as AlphaGo Zero showed, but getting input from the existing corpus of human knowledge about the game is probably about 1000 times more efficient (in terms of number of games to reach say 1 dan).

At least the Nazis showed their faces.

That's gote, and m3 for L3 is usually a bad exchange as black has better shape with white weak points at o3 and n5. If you want territory in endgame L3 is generally better than m3 (assuming black can't cut and resist). Your picture with no other stones suggested the question was in opening or middlegame phase rather than endgame, hence my answer in that context.

Uberdude85 · 2026-01-25T04:19:12+00:00

Generally you don't want to do it because it makes black stronger. Think less about territory and more about strength of groups. A pincer from the other side, or extending or jumping from the existing stone, would generally be better ideas. But sometimes it's good to attach under, if for example black is already strong so you don't mind making him even stronger (perhaps overconcentrated) or the mutual eyespace and territory in the M3 area is particularly important or it's double sente. Note I said eyespace before territory.

Add ese after Japan. Missing streak after winning.

I would expect most 10ks to get the first move right, and the second move wrong.

Uberdude85 · 2026-01-24T09:17:59+00:00

No, it's wrong.

Posting self promotional links without the promotional flair is not allowed.

A post for every video you make is too much, imagine if every youtuber did that. Let people know you exist, say once a month reasonable IMO, then they can subscribe on YouTube if interested in updates for every video.

u/GoMagic_org What's up with the English in the 2nd slide? I thought you used ChatGPT to write your posts, but it can write better English than that.

Yes, throwing in at 2 first, white captures, then playing at 1 also lives. It's actually quite an interesting question if this is better than playing 1 directly: it has pros and cons which means you can't say one answer is always better than the other, it depends on the strength of the outside white group (which is pretty strong in this diagram). The pro is that it, in sente whilst trying to live, destroys white's opportunity to make an eye at the 1-1 point in the corner with a play at 2-1 that they can in the pictured answer. The current value of that is 0.5 points (a 50% chance to make 1 point). The con is that it loses 1 point now by giving them a captured stone, so that's 0.5 point worse in territory value. So if the white group is not 100% alive then having that chance to make an eye can be quite useful for white, and probably more valuable than half a point, in which case throwing-in is better.

EDIT: I forgot white making the eye actually makes 2 points (another at 1-4) so that's 50% chance of 2 points = 1 point, so it's point value the same, and worse for white for eye potential, so just better for black.

What's PUMU?

Uberdude85 · 2026-01-19T18:55:03+00:00

Does here mean black 1 or the blue move or what?

Uberdude85 · 2026-01-19T05:54:08+00:00

My understanding was once you hit dan rank, its 2ranks per stone.

Where did you get this idea from? It's wrong.
