In the history of Go in the 20th century, Master Lee Chang-ho and Wu Qingyuan were recognized for creating a dominant chess player of their own time. Master Wu Qingyuan beat all the top Japanese Go masters to relegation in the Juban Chess Game. Lee Chang-ho jiudan, in his career, reached the finals of the World Series 28 times, winning 17 world championships and 11 world runners-up. Such achievements are also unprecedented, and can be said to be unprecedented. In Lee Chang-ho's time, the chess players who played with him had a common feeling: it was despair. A chess player once described his match with Lee Chang-ho like this: Lee Chang-ho is always half a step in front of you, feeling that a little force can be surpassed, but no matter how much you try to surpass him, he is always half a step in front of you. Such a half-step is very desperate. Because you've done your best, but he's still half a step ahead of you until the end of the race.

In 2017, in the first round of the human-machine war between Ke Jie and Alpha Dog, Alpha Dog won with a half-eye advantage. After the game, the top professional chess player commented that although the result was that Alpha Dog half-eyed won over Ke Jie, the gap between the two sides seemed to be very small. But the actual alpha dog's lead has been several eyes, and the alpha dog has adopted the most secure way to win: winning the game without making trouble. So, though looking at both sides the level is very close. But in fact, Ke Jie did not have any chance.

When Li Changhao first debuted, Ma Xiaochun, the leader of Chinese Go, said that he and his opponent had a 52% winning rate, which brought a lot of hope and despair to domestic chess fans, and for a whole era, Li Changhao was the nightmare of Chinese chess players. It can be said that the national Go fever set off by Nie Qisheng was almost extinguished by Li Changhao.

Ma Xiaochun's self-confidence is not a blind self-confidence, but a kind of self-confidence based on the comparison between Lee Chang-ho and his own chess style. Many of the top chess players felt this way, including Lee Chang-ho's master, the Emperor of Go, Cao Xuanxuan Jiudan. Cho Hyun-hyun Jiu-dan also did not appreciate Lee Chang-ho's chess style. But what is valuable is that he did not interfere with Lee Sung-ho's style of chess. What makes Cho Hyun Hyun Jiu Duan more depressed is that even if he is, it is very difficult to win Lee Chang-ho's game of chess. And I still can't figure out why I can't win him? If you want to talk about Go talent, I'm afraid that except for Wu Qingyuan, no one admits which player's Go talent can be above Cao Xuanxuan.

In this way, Lee Chang-ho defeated all the chess players of his generation with his "turtle speed Go" and won the almost superstitious worship of Go enthusiasts around the world.

So why is Lee Chang-ho so strong? Many people believe that Li Changhao's layout and strength are average, relying on the official divine skills of the world to reverse the situation. Is this really the case? Fortunately, now that there is super AI, you can finally use AI to get a glimpse of why Lee Chang-ho is magical.

Some Go enthusiasts analyzed lee chang-ho's seventeen-crown final chess game through kata dogs. The statistical indicator is the 50th lot winning rate. In a 5-and-a-half-mesh match with black and white, the initial win-win ratio of black and white is 55:45. Black paste 6 1/2 mesh match, black and white initial win ratio of 49:51,Black sticker 7 and a half mesh match, black and white initial win ratio of 41:59. Based on the initial win rate, when the 50th lot win rate is higher than the initial win rate of 5 points, the layout is considered successful and marked in red. If the difference between the winning rate and the initial winning rate is within 5 points, it is considered to be equal. The win rate is lower than the initial 5 points, and the layout fails, marked in green.

A total of 54 games of chess, analysis results: Lee Chang-ho layout successfully 30 games, layout failure only 13 games! The layout was successfully reversed by 6 innings, and the layout failure was successfully reversed in 8 innings.

If you don't consider the first two Toyo Securities Cups (when Lee Chang-ho was still young), then the success and failure ratio of the layout is a terrifying 28:8!

It can be seen from this that Li Changhao's strength and the level of officials are only a part. The layout, which far exceeded the average of its contemporaries, is also extremely important. The main reason why the layout brings advantages, and then relies on the official shengong to transform the advantages into victory, is the main reason why Li Changhao is strong.

Lee Chang-ho is 13 sets behind in layout, and can win back 8 sets, with a success rate of more than 60%, indicating that Lee Chang-ho's strength in the middle game is also very strong, and his ability to stir chess is also first-class.

Before the emergence of AI, the layout of the game between the top masters is good or bad, it is difficult to quantify the data, so almost all chess players think that their layout is better, few chess players think that their layout began to fall behind, in fact, when playing with Lee Chang-ho, after 50 hands, 78% of the chess players have fallen behind. But the player may not feel it yet, or even feel good about himself. In fact, it has fallen behind, but it is not judged that it is already backward, and the strength of the central market cannot suppress Li Changhao, and the fineness of the officials is not as good as That of Li Changhao.

That is to say, Lee Chang-ho's technique is very comprehensive, there are no shortcomings and dead ends, and his understanding of Go is: life is like chess, and you must not be greedy!

Lee Chang-ho's Ten Tips for Go in his book "Don't Be Greedy":

1. Do not be greedy: the more greedy you are for victory, the more you will not be victorious;

Lee Chang-ho's understanding of Go is very similar to AI, so Lee Sedol said that in his view, Lee Chang-ho was the god of Go at that time, that is, AI.

The fundamental reason why Lee Chang-ho can achieve such great achievements is that his understanding of Go is close to AI and surpasses his contemporaries.
