Life In 19x19

I'd say the main characteristic of the tournament scene of the past few years has been the rise of the teenybopper. Looks like things are changing now.

Below are the top ten ranking lists for the three CJK countries in 2010, with ages. Although the Korean and Chinese lists still have a youthful air, teens are now becoming like hen's teeth. Japan remains the country of Gaudeamus igitur, veteri dum sumus, with not a single teen in the top 20. On the other hand, they are the only country to have a woman in the top ten.

KOREA
1. Yi Se-tol 27
2. Pak Cheong-hwan 18
3. Ch'oe Ch'eol-han 25
4. He Yeong-ho 24
5. Weong Seong-chin 25
6. Kang Tong-yun 22
7. Yi Ch'ang-ho 35
8. Kim Chi-seok 21
9. Pak Yeong-hun 25
10. Cho Han-seung 28

Plus two more teens in the top twenty. The top oldie is Cho Hun-hyeon (25th) at 57, and next is Yi Ch'ang-ho.

CHINA
1. Zhou Ruiyang 19
2. Xie He 26
3. Kong Jie 28
4. Gu Li 27
5. Li Zhe 21
6. Wang Xi 27
7. Tuo Jiaxi 20
8. Jiang Weijie 19
9. Chen Yaoye 21
10. Gu Lingyi 19

There are no more teens in the top twenty. Zhou Heyang (15th) and Chang Hao (17th) are the oldest in the top twenty, at 34 .

JAPAN
1. Cho U 30
2. Yamashita Keigo 32
3. Iyama Yuta 21
4. Takao Shinji 34
5. Hane Naoki 34
6. Kono Rin 29
7. Yamada Kimio 38
8. Xie Yimin 21
9. Cho Chikun 54
10. O Meien 49

The CK lists are based on their country's ranking systems. The Japanese list is based on tournament winnings. Cho U made 90 million yen in 2010. Mimura Tomochika in 20th place made 7 million yen (not a lot). There were no teens in 11th to 20th places. If anything, while there was much less gold, there was even more silver.

I'm amazed Cho Chikun stays competitive at his age.

Especially when you see his picture here:

He looks like the crazy uncle that everyone avoids at a party.

My Cho Chikun anecdote: after the end of the second day of the 1999 Kisei (where I got my avatar photo with Takemiya), I was leaving the hotel in Paris where the game was played, and he and someone else came running up to the elevator I was in alone. I didn't know what to say, so I just bowed, and he bowed back.

*snip*

I dunno, when I see that picture I find it more plausible, the 'crazy uncle' look seems to include some vitality. He doesn't look 64 to me.

Maybe I'm biased because I think his hair is awesome.

Cho is one of a kind. Very free and wise looking!!!!!!!!!

Maybe because Cho Chikun is 54 years old, born in 1956.

Cho Chikun has always reminded me of Columbo (TV detective played by Peter Falk) -- unkempt but brilliant.

The reason why is obviously because the level of competition in Japan isn't very high.

nice troll

I've seen the term troll used a number of times on this forum but I'm not sure exactly what it means.

I'm serious. There's no way that he should be in the top ten at 64(let me give you that one more again. Sixty. Four.), if the country he's playing in is sufficiently competitive.

This is what a troll is.

I recognise that my post could or would inflame some. But my intent was not to provoke. I simply could not let emeraldemon's post go unanswered. And it most assuredly was not off-topic.

Half the people on this forum seem to be mathematicians, ask any of them what affect age has on mental functions. And yes, I'm aware that dimunition of capability is different from person to person. But to imagine that at 64 Cho Chikun is around about the same strength as Yi Ch'ang-ho at 35 seems to me to be far too implausible to be credible.

Thus my earlier conclusion.

This discussion has been had before. In the first case, why do mathematicians have the primary authority on the impact of age on performance in Go? First you'd have to show that math and Go are similar enough for comparability. There are different kinds of mental functions, you know.

Different academic fields can have very different ages of deterioration, not that any of those are more or less likely to be relevantly analogous. Unless specific studies are going to be conducted or other evidence is provided to back up these claims, I find your certitude far more problematic than the notion that a professional Go player could remain competitive at 54 (noting Vesa's correction), simply because Cho Chikun does in fact appear to be performing competitively. That is far better evidence than wishy-washy anecdotal inference based on comparisons between an academic field and competitive board game or your initial declaration which didn't even include any supporting remarks.

Rin Kaiho made the semifinals of an international tournament at the age of 58 or 59 in the year 2001. Cho Chikun won an international tournament in 2003, at the age of 47. Cho Hunhyeon won one at the age of 49.

You simply have no idea what you're talking about.

To spell it out a bit more, even if age has a pronounced effect on mental function, so long as there is a range of variation, you can infer very little from the fact that one older player does well in his nation (note that Cho is very much an outlier in Japan). Maybe you could ask those mathematicians about statistical inference.

Btw: I do think that Japan's level is definitely lower than China and Korea, though various attempts to quantify it haven't been as dramatic as you might think. But a bad and overstated argument for a true conclusion is still a bad argument.

You realize that Japan is also the country with the oldest professional system... and thus have more pros at that age, right?

China got its first pros during the Nie Weiping era, and Korea got its first pros during the Cho Hunhyeon era.

That's 80's and 90's, before that, there were no pros in either country.

Compare that to the Japanese, who had a pro system in place before that. Obviously, there were more pros at the same age in Japan than in the other countries once all three had a pro system, including the dominant ones like Chikun, Kaiho, Kobayashi, Takemiya, Yoda, etc.

There was a higher concentration of them than the other countries, so it's not that unheard of that we seem a percentage of them rank high competitively even now.

Especially when you consider how dominant Cho Chikun was.

To just say that, "Oh hey, Japanese people have an old guy in their top 10? They must suck,"

is an ignorant statement of quite a large magnitude.
