I might be completely mistaken, but I thought the main thing that Go game commentaries provided (like all game commentaries) was entertainment. I'm not saying that some people don't study game commentaries, but I believe that the teachings are intended to deepen appreciation and enjoyment of the game. Not to improve skill.


It's infotainment. When you listen to a teacher in class, that's like a commentary. You typically learn very little there, but you are put on the right path: true learning only comes when you do your homework. But if she does her job well, you will be inspired and so pay extra attention to your homework, try harder, and even maybe do some follow-up of your own with a visit to the library. You will also be guided by being alerted to tricky technical details, and shown how to think. That's the info part. Appreciation and enjoyment are bonuses which lead to wanting more info, and so a virtuous circle is created.

I don't think there's much of a market for a book that begins "Guy walks into a bar and the bartender is a gorilla," although my Go Companion might contradict that. In any event, it's a much more limited market.

Contrary to John's experience to train intuition, replacing subconscious thinking by reasoning has enabled me to become stronger.


I've read a few books on the brain which (combined with my own experience) have led me form some opinions, but I freely admit I can't directly make those opinions stand up.

That said, my current understanding is that there is no such thing as subconscious thinking. It's more an intricate system of information retrieval which is triggered by various stimuli, which can include conscious thinking but also extraneous events such as an itch in your armpit or a fly buzzing round your head. Furthermore, what you get when you retrieve information triggered by conscious thinking is not necessarily what you expect. Various associations (such as that fly) may trigger extra data, either unwanted or actually rather interesting.

But because what is inside your subconscious brain is based on probabilities, you can control to some degree what comes out. If you work on life & death problems with intent focus, and then see an L shape in a game, the mantra "the L shape is dead" is likely to flash into your mind. But if you work on L&D on the train home every day while eating messy snacks to stave off the rumbling tum, chatting to your neighbour, checking your emails and keeping an eye out for your stop, what might pop into your mind in the game is not the "L shape is dead" but something like "Oh, I wouldn't mind a cheeseburger right now."

In your case, I suspect that you have the ability to work intently with great focus, and that leads to the information being stored in your subconscious having a high probability of being go related, and apart from that being new information, it will also reinforce whatever relevant information is already there. Whether that leads to becoming stronger on the board can only really be tested (for amateurs) by achieving a higher dan grade, but I would expect that it would make you feel more comfortable at the board when dealing with new situations. Your uncertainty would be reduced. Since "understanding" is a loaded word in a game that is rife with uncertainty, I would argue that it's better to avoid that word. After all, we don't talk of AI bots having any need to understand. Any feeling you may have that your rationality is controlling everything is a delusion. It's just a factor that helps determine what goes into or comes out of your subconscious.

Quote:
Numbers in positional judgement, endgame or semeais reduce (and sometimes eliminate) uncertainty.


I don't accept that for positional judgement, at least not in the way you do. I had a good real-life example last week of the problems with numbers. A teacher, who happens to be a mathematician, was taking a dance class for some beginners practising for a ball. There was an intricate move that was causing some problems because of the speed at which the move had to be done - as dictated by the music on his iPad. People were bumping into each other. So the teacher went to the iPad, twiddled some virtual knobs, and then came back and announced he had reduced the speed of the music to 96%. He instantly noticed the whirring eyeballs and blank gazes. Uncertainty has risen by a factor of 1.7358. And so sheepishly added, "Well, we've paid for the software so we have to get our value out of it." All he had to say when he came back from his iPad was, "OK, I've reduced the speed of the music a wee bit" (or say nothing) and the uncertainty among the beginners (which would be partly psychological, of course - nothing to do with numbers) then have been massively reduced.

As it happens, at the ball a few days later, with a live band, a glitch occurred in that movement in one set. The live accordionist spotted it from the stage, and instantly played an extra bar in the 8-bar measure. Just enough to solve the traffic problem. An iPad couldn't do that. Furthermore, the other musicians took their cues from that and all the experienced dancers in the hall also coped seamlessly with the extra bar, without having forewarning or any time to think what was happening. They just followed the flow of the music and relied on intuition to adjust their steps. I would guess many of them weren't even aware of what they did. In other words, they relied on intuition. Rational questioning would have led to collapse of the dance.

There are various factors other than "objective" rational thinking that affect our choice of moves. When we "think" something can be done in a position we are more likely to make self-serving moves. When we are under pressure, such as being in a kadoban, we might pull in and become too passive, or maybe we'd play unreasonably. Perhaps many of us have lost games where we had a large lead by playing "safe", allowing our opponent to catch up. We have a sense of risk when playing, perhaps connected to uncertainty, and playing to lessen risk is understandable. We are given advice to play moves we understand, which reduces uncertainty, but will we always understand the moves our opponent plays? So uncertainty is unavoidable.

To start with the obvious: the current territory count of the territory and territory-surrounding intersections is a number used in positional judgement reducing uncertainty by
assessing the almost settled part of the board and leaving only the rest of the board significantly more uncertain.

One question I have is if Lee Sedol actually wrote any of this. Ghostwriting takes many forms and it is sadly rather common.

My impression from reading Vol. 2 is that he wrote it. He points out his appreciation for help preparing the book. There is surely a professional writer and editor like with many books, but this book seems to genuinely be his. Here is a snip from the beginning.

Baduk was always on my mind during my leave, even though I didn't play. Fortunately, preparing these books filled the void admirably.

I want to express my gratitude to my family for assisting me in so many ways, Mr. Hong Taesun for gladly donating a camcorder to record my comments, [etc].

By the way, my impression is that the NHK Books from the Go Focus lectures are actually ghost written. But that is actually a good thing isn't it? The Go player has already prepared the lectures and given instruction. The only thing the writer does is write the main points and prepare the diagrams.

I had some cynical thoughts when reading "professional writer" but I'll let it be. The sniped is in Lee Sedol's name and certainly does appear somewhat personal. I was more interested if the commentary is Lee Sedol's or if there were helping hands. Maybe that is a ridiculous question if you have one of the books open in your hands.

Regarding NHK lecture series. I don't have them either but I don't see a problem with a second author or editor adapting a lecture into a book. Like you say it can be beneficial or the lecturer simply isn't interested in doing the work. It is too bad if this is not acknowledged properly, I take it that it is not clear.

AI analysis is not, repeat: NOT, objective. It may be helpful and provide a new view but this does not make it objective. AI can err and has erred, e.g., judged two very similar positions very differently or life and death status wrongly.


In this context, I merely meant that the AI is without emotional bias, not that it was the “objectively right” move. I realize that the word is used that way when discussing game evaluation, so it was a poor choice. Sorry for the confusion.

I fully agree that a bot, even a strong one, can have an algorithmic bias. And I agree with others in this thread that it’s possible for a move to be good for the bot, but not good for a human. But I am in some doubt that a move chosen by a player of Lee Sedol’s caliber during a game that is validated by AI analysis later was actually bad when he chose it. It could be, I suppose, that he couldn’t actually play the follow-up, or that his ideas of why it was useful was wrong and therefore he shouldn’t have played it to begin with. But I think it’s just as likely that it was a fine move in the flow of the game, but an emotional response (or incorrect re-evaluation) in later analysis caused him to incorrectly decide it was poor.

It's one of the most personal books by a pro I have ever seen. There will surely have been some help in editing but I genuinely believe the commentaries are his. The commentaries are also spiced up with stories by himself and his sister.

This is also why I find the comments so interesting, because (I believe) they show the emotional bias with which certain moves were played or even discussed in retrospect, as exposed by the more objective (I believe) AI.

I'm also trying to take Lee's strong claims more like his own positional judgment. And when you're the strongest player in the world, you're entitled to leave out the nuances of "in my humble opinion". As said, the exercise of reviewing it with KG is valuable to me.

If I may, a question for both you and Robert, one I ask because I haven't a clue what the answer is. I don't study, but you both do, intensely, and so may have some insight I've missed.

Neither of you seem to have reported any significant increase in grade. At most, I imagine it would be one amateur dan. You may feel stronger, but that's more about appreciating the game as a fan, rather than as a competitor.

But at the same time little Sumire is winning game after game and has already bounded up to 2-dan in a very short space of time (I'm assuming a pro grade promotion is harder to achieve than a low amateur dan). I pick on her because she has to spend a lot of time on schoolwork and sleep longer than adults, and so in some sense is comparable to amateurs as regards how much time she can spend on go.

Have you got any sense of what she's doing that you are not doing, or advantages that she has that you don't? I'd be reluctant to put much emphasis on DNA, or even on the nebulous concept of talent. Starting young must help, I suppose, but have you any sense of specifically how this might help?

I have not found many reliable clues in the literature (including chess). I have looked, because my next book (currently being proof-read) is entitled "Ogawa Doteki, go prodigy." I have incorporated there a brief survey of many other go prodigies. One that does seem to percolate through most biographies of top players is that enormous emphasis is put on ultra-basics. By that I mean something like tactics as pure tactics. Adult amateurs seem to bring strategy into the mix far too early and justify tactics in terms of strategy (or efficiency or positional evaluation). My feeling is that they are trying to run before they can walk. I'm guessing that youngsters don't find pure tactics as boring as adults do. In go there is also a great emphasis on even talented youngsters playing handicap games (where the handicap stones take out some of the strategic complications and allow tactics to flourish unencumbered. Western amateurs are, in contrast, notorious for avoiding handicap games, and many even try to insist on playing even games with stronger players. They seem to be in love with fuseki and out of love with tactics. But is it not likely to be true that you can't appreciate strategy properly until you have a really thorough stranglehold on tactics?

Outside of go, in talent shows, for example, young people described as "talented" are usually (?always) just perfect mimics of adult stars. Can we view mastery of "tactics as tactics" as go's equivalent of such mimicry?

But I am guessing. Hence the question. I'd like to put the same question (what have Sumire and her ilk got/done that you haven't got/done?) to any other amateur who studied very hard, with or without AI, and didn't get to the elevated dannage they'd hoped for.

Well, it's not entirely true: I do feel a change, backed up by regaining a solid 2d rank on both OGS and KGS. But indeed I have not gone beyond that, into the 3d-4d realm, whether or not I study a lot. And I think that's where my ceiling is really, if not 2d already, due to a mixture of talent, time spent/available and age.

- Talent: this is the hardest element to measure. I've seen people with a better capability of move selection, remembering tesuji, keeping their head cool ...
- Effort spent: these days it's about a couple of hours per week. Say 4 games, of an hour each and about the same time analyzing.
- Age: I believe both Robert and I are born in 1971.

Anyway I would never compare myself to a young Asian professional. That's just another game, in all meanings of the word.

On this part, I don't think I have ever shied away from tactics and have not spent too much time on opening/strategy. But I do feel that my tactics are not solid. As my mistakes series shows, there are still too many blunders and a laziness/incapability to read.

What I mean is that I don't play and so don't study to become stronger in competitive play. Most of my books are about go personalities and so much of my time is to do with researching their biographies and backgrounds. I accept that in the course of going through commentaries, say, I may become better at understanding aspects of go (in fact I'd be a bit worried if I didn't :)). But that's just a spin-off, and I don't think it translates into strength on the board. because non-go factors such as desire to win, concentration and general match fitness are all lacking. I am a go fan rather than a go player. A bee rather than a workhorse. I absorb go's nectar in the hope of being able to produce honey.

It's helpful to think of KataGo's opinions as being similar to that of a strong pro. Maybe prior to 2016, you had a favorite pro to study - maybe you liked their games or commentary. If that particular pro wasn't the number one player in the world, does it make their commentary invalid? Of course not.

That's because the "blue move" is not really what's important. What's important is the thought process used to try to get to a blue move. Even pre-AI there were out-of-date joseki that were no longer considered even for both sides. However, it's totally educational and valid to study those sequences and understand the reasoning behind the moves. Furthermore, those sequences just might be the correct sequences in certain circumstances.

One thing I've found interesting in listening to Inseong's lectures on various patterns is that he'll give the recommended sequence, but also show variations that aren't recommended for whatever reason. But he makes the comment that, "If you like this result as black, then you can consider playing it." So it's not really like, "Don't play this way because pros have deemed it inferior", but rather, "here are some different options you have and what kind of board position you'll likely get if you play it out".

This way of thinking is more useful. If you play a game and are in a tricky situation, understanding what options you have and making the game flow according to your plan is more important than a "blue" move. After the game, if you played out your non-blue sequence and lost because of it... then you can think about what alternatives you may have wanted to play.

tl/dr: the thought process and sequences are more valuable than the answer itself

Have you got any sense of what [Sumire 2p is] doing that you are not doing, or advantages that she has that you don't?


(Earlier, I have mentioned to have much improved due to replacing subconscious thinking by reasoning. This refers to my improvement from 5k to 5d, which was very fast to 1k, fast to 3d and reasonably progressive to reaching 5d in 1998. My 5d of 2022 is stronger, maybe 1 rank in terms of 1998. Therefore, the remaining question I am trying to answer below is: why has my improvement been slower since 1998 and not surpassed 5d?)

When I started go seriously, I was almost 21. Therefore, I missed the advantage of somebody starting as a child. If I had the chance, I could have started seriously at the age of 4.

I have not had the playing environment of an east Asian prodigy, who might have the chance to play equally strong human opponents every day. I had to travel throughout Europe to tournaments to have more interesting games.

While I could spend an average of 14h per day on go from 1993 to 1995 and a bit less to 1998 (obviously while neglecting university study), I studied go rules more than go from ca. 1996 to ca. 2006 because, for me as an advanced amateur mathematician, playing a game with ambiguous rules was unacceptable. We are aware of the importance of fundamentals and I take them more seriously than most: they start with the rules. Hence, my rules study time has been unavailable for go theory study time.

Eventually, the necessities of life caught up. Although my jobs are go-related, study during the job does not even remotely compare with separate study for improving. IOW, I have had too little time for the latter. If I had started go 17 years earlier and not studied the rules, I would have had very much more time on studying go for improving.

I have not seen any flawless IQ test so my IQ of 155 is just an approximative guess. The level is not bad but there are always more intelligent people with IQs around, say 170 - 190. Or you might say: greater talent. Go playing strength can be the result of time, effort (aka hard work), environment and talent. I could have invested more hard work but cannot compete with greater talent, except by even more hard work that I should have done. You know, instead of TV during the evening, solve another 100 problems.

When I compare the go skills of pros and myself, I notice two major differences: 1) their faster life and death reading, 2) their faster endgame value calculations. Both I might achieve by more hard work. When I compare stronger amateurs, they also make fewer blunders on average (where we speak of high dan blunders rather than fast server game fun) and have a bit better understanding of some other go aspects (example: they can use thickness better on average than I can). It does not matter enough that my understanding of some yet other aspects is better.

More talent would help but what really makes the difference is willingness and time / money to spend day and night, year after year on hard work of studying.

Like the athletes is international events. They train many hours every day for many years.

It is like I did for go theory research on rules, endgame, ko etc. There, I have achieved what might belong to world-leading standard. However, the time spent for it I have not spent on separately studying go directly for improving.

If my opponents have better advice of improving than more time, more focus and more directed hard work, please let us know! :)

OK. I'll consider it as coming from Lee Sedol. My reason for raising the question is that some Go books obviously have minimal input from the credited author or have otherwise become remote from this input in the English translation.

I tried to continue the discussion by sharing what I see in the first game with the help of KataGo but this thread is wandering off to other topics quickly.

It is hard to say much about the second game. It is almost error free in the opening and early middle game but almost every move from 150 - 181 is a bad point loss. Lee Changho wins this game despite making a -12.1 point move at 181.

I read your observations about the comments on the second game:

I don't understand what KataGo is telling me about move 22 but there doesn't seem to be any benefit in making the inside cut instead of the hane.

The 37 - 47 does seem to squander blacks advantage but I think mostly because 43 is an overplay.

Black's 83 - 101 action effectively gives white the lead, I am concluding that players didn't have close to the same assessment as KataGo because the game is B+0.3 at move 82 but white has a chance to be W+9.6 at move 100. You mention 99 - 100 as appearing in the comments but what I see in KataGo is Lee Changho almost throwing the game and Lee Sedol not completely taking advantage.

Then there is what I said above about moves 150 - 181. I wonder if there is any word on that in the commentary.

I think the most interesting comment that you posted from the second game, Knotwilg, is that Lee Sedol felt “white’s flow was unfavorable.” You can see from KataGo’s analysis that the game was pretty even at the point where he wrote this, but it sounds like he didn’t get the game he wanted. This bring us back to some of the earlier discussion on the first game: the overall result wasn’t bad, but perhaps it was bad for Lee.

This is, overall, an interesting way to look at professional commentary and how to play the game of go. Each of us is making choices, and we can try to direct the game toward one that is favorable to our strengths and preferences. I wonder how many of my clear blunders (which are many at my level!) come because I let myself be lead into a situation that doesn’t play to my current strengths?

Just to go back a bit... The opening post is about how Lee Sedol's judgment of a move or position may have been biased and how the judgment is sometimes different from AI judgment. Having looked again at Vol. 2 (I don't have Vol.1) I just wanted to point out that even if Lee Sedol's judgment is wrong (I don't think so), his judgment is not the teaching point of the commentary. Lee Sedol teaches techniques for making your own judgment (summarized):
  • Taking profit at the beginning makes the game easier to play, but giving away too much thickness may cause you to lose initiate. Maintain balance between profit and thickness.
  • If preferring thickness, do not fail to take the initiative using thickness.
  • Do not obsess over an area where the opponent did not respond. Punishing tenuki may not be big.
  • While being attacked, continuously aim at the opponent's weaknesses.
  • Escaping with poor shape may be better than settling quickly.
  • If you focus on playing too safely in a game you're winning, it might keep you from seeing good variations. Protect against weaknesses that might reverse the game without being passive.
  • Read and be confident if you attack in the beginning of the game.
  • You may need to play a bad move to defend a weakness in sente, but that might be worse than just defending in gote. Be certain about the benefits.
  • If you always play proper book moves, you may miss a practical move for your situation.
  • Judging a move to be absolute sente and missing the chance is a weak point for pros. It is not easy to determine the right timing for exchanges. It might be beneficial or might lead to a loss.

It should be no surprise that KataGo has different judgment from Lee Sedol. But KataGo cannot provide better judgment-techniques or even assess whether these techniques are good or bad.

Thank you for sharing so much. Both what you mentioned and didn't mention was interesting. I had hoped for some discussion of what an adult focuses on as opposed to a child (as I said in my question post, I suspect adults focus far too much on strategy), but at the same time I admit I did stress that my choice of Sumire as a comparison point was more to do with her having far less time to study go than post-school pros, and so seemed a better fit for us amateurs.

However, I am planning to post something soon about Sumire which I think will feed back into this discussion (though I will post that in the Sumire thread for the sake of tidiness).

I don't believe go is any different from chess, shogi or xjianggqi in that you should study closed positions, the endgame and tactics, first. Because the point of the opening is to get to the endgame so studying tactics may help one's opening, but not the other way around, probably :).

When I was a more wee lad, my view of any expertise was such that of course, I am completely incapable of understandiing anything to do with the subjective opening and of course must rely on the prophetic words of the pros. I just didn't even see how it was possible for humans to have developed an intuition for the opening, so the fact that pros have one to a significant degree must mean they have magic powers I must pray to absorb :), and I was specifically interested in reviews where different pros commented on the same game to see any differences in opinion, especially in the opening. Now it seems to me that those intuitions were based first on tactical consideration.

In chess and chess-like games, I had the opposite problem to Taranu sensei, which is that in go it was easy for me to have an intuition of where I wanted to play, whereas in chess I have no idea how any opening relates to somehow ambiguously helping you to capture the opponent's king/general. I mean what does pawn to e4 have anything to do with how I can eventually capture the other side's lead piece? Or protect my own?. So, in the case of chess for me I guess it's more obvious to do what the well-known chess saying says; study tactics and second half of the game first, and the first half of the game should take secondary priority or be studied afterwards, I guess.

A is the tendency. So this means playing moves in the opening that are not necessarily the best, but wanting to win through the pure willpower of intention, and this usually leads to fighting. I think this also makes both of us like reviewing games; at least An Youngill said specifically he likes to do so, and. This intention means However, I happen to be familiar with someone who shares an exact gene with him that I don't, and I know what it does. It means him nd I both complain about the structure of whatever pro organisation we may be in, but he is more likely to get very frustrated and resign, and get stuck on a solution that may not actually work, and be absolutely frustrated with bot's abilities to swerve him, in the opening haha . . .

Actually, I've studied people down to the likely precise set of genes in terms of behaviour, so of course I've seen other amatuers where I think, 'wow, their "style" is just or very similar to so-and-so pro'. Most strikingly a sister pair who's styles are basically Yu Zhiying and Choie Jeoung, and the proof was that their personality types were also similar, as I mentioned many years ago.

Choie Jeoung has a gene that probabilistic situations--exaclty as would be useful in the endgame and chaotics fighting, as An Youngill said she was good at. Yu Zhiyng has a realist personality element that overpowers any tendency of women towards fighting games. Does it mean that we interpret mindsports in the social category of our brains, for that would make sense for women to then be more aggressive in it while men are generally more catious? Interestingly, my tendency to start fights is regardless is apparently the hallmark of feminine go, and we all know what happened with Korea, and it's strange that I haven't seen this point belaboured more. Did the Koreans get stronger by playing more feminine go?

It's probably more important to find a pro with a similar personality type to you, and study them. This is a current limitation of AI, I guess. In that case Tasmin Jones was right, and I've now moved more towards her opinion; we should imagine as amateurs we have a style, even if it's one that doesn't exist yet. It's strange that I'm saying we should study pro games more like aesthetic art pieces, but I am. In fact, studying a pro game hoping to glean objective facts to improve is likely exactly what would guarantee you won't improve. his is the mistake I made because of my view of expertise as god-like, haha. Studying pro games subjectively, tapping into the emotional center of the brain, is likely better, and children probably do this better than adults, so that might exlpain Robert Jaisek's findings did do better relying on non-intuitive based study later on, but that's likely because his initial intuitions learned as an adult where only as good as most adult brains can make them, so an 'adult' brain, one that's tired of growing already, likely is more dependant on that kind of thing :).

So pro opinion in go can have as much to do with genetics as actual ability. And of course, which teacher you had, which go dojo you had, whether you learned go in the honinbo house or some other house that has their own fashion and dogma for the opening, in which case the point is very obvious. I think we amateurs think pros have moved on from those days, after shin-fuseki, but maybe it's a delusion, maybe not as much as we think!
