without any ideas or examples to back it up.

1) For an example to back it up, see above.

2) In the other thread, the purpose was just to give a hint, instead of derailing that other thread.

3) Since you want to see more typical 1d gaps related to fundamentals, see below.

*****************************************************************

- They know that they should avoid blunders, but their blunder rate is ca. 2 or 3 per game on average.
- They know that there can be different answers to a corner approach, but they do not always decide among tenuki, extension, pincer or blocking the corner. Instead they sometimes consider only part of these choices.
- They sometimes construct a moyo of intermediate size along an edge, thinking it would be territory and so omitting a reinforcement. Their strategy is spoiled when the opponent simply invades.
- They do not always do proper local move selection.
- They often rely on a proverb for choosing extensions, instead of verifying their connections tactically.
- They are sometimes unaware of endgame aspects relevant during opening and middle game. (Don't play just some move, but a move fulfilling a major purpose with also the best impact on the endgame later.)
- They sometimes choose strategies purely for fun, instead of verifying whether they can also be justified.
- In a tournament game, they spend 5 minutes on a life and death problem to verify death, but sometimes overlook ko.
- They are occasionally completely surprised by stronger players' sacrifice strategies, which they overlooked completely.

EDIT: typos.

There is no way for me to agree or disagree with idea that a 1 dan half understands the fundamentals. There is no consistent definition for 1 dan, after all. Also, even if there was, I suspect it is possible to come up with some definition of fundamentals so that the halfway point fits any desired rank within some wide range. But as for the list, I'm not sure all can be considered concepts. For some items, I don't think they mean anything as stated.

- They know that they should avoid blunders, but their blunder rate is ca. 2 or 3 per game on average.

This seems more about conditioning and practice than lack of a concept. What's the concept? Avoid blunders? One might as well say that winning the game is a concept. (And I guess it is, but is this worth stating?)

- They do not always do proper local move selection.

This is vague. Except for the "local" qualifier, this is like saying "sometimes they don't play good moves" which is not very interesting.

- They sometimes choose strategies purely for fun, instead of verifying whether they can also be justified.

Maybe a meta-concept. Also, are you certain this disappears at 4-5d? There may be a slow dissipation as rank increases. I could be convinced to hand you this one as a possible observation.

- In a tournament game, they spend 5 minutes on a life and death problem to verify death, but sometimes overlook ko.

Again, it is possible to distinguish concept from conditioning here? Is there a high incidence of 1 dans slapping their faces and muttering, "I forgot to look for the ko!" (This would be distinct from "I didn't see the ko!" which may be common enough.)

Just as a random comment, Guo Juan 5p has a series of lectures on her internetgoschool.com site titled "Typical Mistakes 5k-3d." Maybe for fun I'll look at them again to see how many were conceptual.

Having fun is all the justification you need.

All of your comments can apply to 4-5 dan as well, which is why I found your previous statement in another thread amusing.

RobertJasiek wrote:- They know that they should avoid blunders, but their blunder rate is ca. 2 or 3 per game on average.

What sized sample was used for this? What constituted 1d? What's a blunder exactly? I've seen definitions ranging from "a mistake below your level" which is extremely vague to "unforced error" which is much more tightly defined yet what constitutes an error is something we could get very caught up on, what is our horizon? Is a move our opponent shows to be in the wrong place 25 moves later an unforced error or are we only concerned with "near horizon errors" that are revealed within a handful of moves?

I'm curious. This strikes me as a very hard thing to tie down and have people agree on.

oren wrote:All of your comments can apply to 4-5 dan as well

But only in fast games, such as server byoyomi-only games. In slow games, 4-5 dan can apply the fundamentals properly. Not all 4 dans, not all weak 5 dans, but IMO all strong or experienced 5 dans. (Except those where the ranking system is down.)

My own experience combined with what I have seen from players around 1d strength.

This, or easily explained by referring to the fundamentals.

Of course.

If it's an anecdote you shouldn't phrase it as a declarative statement of fact.

RJ, Are you perhaps hinting that you will soon be publishing a work which will gear towards low level dans and near dan SDKs as a follow up to First Fundamentals?

I think Robert is hinting that all one dans should hire professional teachers (preferably Asian) as the logical next step in improving. Excellent suggestion. Thanks, Robert!

You know that I may answer such questions only in the Books forum.

No. Fundamentals can be learnt autodidactally (if you have years of time), from strong players (if you have them available), from the literature or from professional teachers of amateur or professional rank. IMO in general, so far available online information is not suitable and sufficient yet.

Yes.

This is vague.

No. Local Move Selection is a procedure known to those who care.

Yes. (Not for all 4d, not for all 5d, but...) The point is: strategies may still be selected by fun, but they are supported by understanding and verification.

Is there a high incidence of 1 dans slapping their faces and muttering, "I forgot to look for the ko!"

No, because a) not every game involves a local LD problem and b) they don't notice everything they overlook.

- They know that they should avoid blunders, but their blunder rate is ca. 2 or 3 per game on average.

I've just been processing a game between Go Seigen and Karigane. Karigane played a brilliant game but made two "blunders". One was called a "catastrophic mistake" and the other a "big slip", costing about 5 and 3 points respectively. He lost the games as White (no komi) by 6 points, which obviously implies Go also made some serious mistakes earlier on. In fact both sides did make several mistakes even though it was considered a truly brilliant game. A least the same sort of blunder rate can be found in just about any decent commentary on a pro game, no?

So, this implies Go and Karigane are really about 1-dan amateur, although the world regards them both as 9-dan pro. Since RJ claims to be about four stones stronger than a 1-dan amateur, he is therefore to be regarded as the fabled 13-dan pro of perfection. (Sound about right, I hear someone mutter.)

This is a good example of the folly of trying to stick numbers on everything.

However, forget the numbers and just look at the words, and I think we have to agree - even if it means a painful look in the mirror - that RJ's list is a pretty good summary of the sort of mess most of us make of go.

Since "blunder" is not used consistently with the same meaning by everybody, we can get wrong counts if we call small(er) mistakes by professionals blunders, but call only big mistakes by amateurs blunders.

Ok, "catastrophic mistake" qualifies as blunder, I'd guess. Study many games by those two players, and you will not find an average of 1 or more true (carelessly accidental and big) blunders.

In fact both sides did make several mistakes

"mistake" is not the same as "blunder". Blunders are a special type of mistakes, those that are made carelessly accidental and are big. Such as simply overlooking an atari on 15 stones, or forgetting to defend a very weak group because of having fetched a glass of water while otherwise perfectly knowing that the group must be defended immediately.

A least the same sort of blunder rate can be found in just about any decent commentary on a pro game, no?

No. Unless you simply count the word "blunder" in a commentary without checking what it means in every case.

So, this implies Go and Karigane are really about 1-dan amateur, although the world regards them both as 9-dan pro. [...]

LOL. Wrong assumptions lead to wrong conclusions.

This is a good example of the folly of trying to stick numbers on everything.

No, but it is a good example of having to check the meaning of what one reads.

Look up what anecdote means in the evidence sense.

Or it points to you not noticing blunders as much as strong players would. That is more likely.
