Cho U took the lead in the Meijin title match against Yoda Norimoto. 3 Chinese player and only one Korean qualified to the semis of the Smasung cup. Nong Shim cup started this year with little success for Korea.

In the top ten Gu Li moved to the second, Pak Yeong-hun dropped 3 places and Cho Hun-hyeon is back at the tenth.

JP Morgan cup is a new international tournament. Strangly there were no playersfrom mainland China in it. The first two round were held this week. The semifinalists are Pak Yeong-hun, Yi Ch'ang-ho representing Korea, Yamashita Keigo from Japan and O Rissei representing Taiwan.

Gu Li became the challenger for the Mingren title. Yoda Norimoto leads 2:1 in the Meijin title match against Cho U.

There are some changes in the top ten. Yi Se-tol edged Gu Li for the second place. Kong Jie moved to the fourth ahead of Ch'oe Ch'eol-han, Pak Yeong-hun moved one place up ahead of Wang Xi too. Cho-Hun-hyeon moved 2 places down to 12th and Song T'ae kon returned to the top ten. Recent success in the Ruisei helps Takao Shinji to hold the highest place among the Japanese, one ahead of master Yoda. Mimura Tomoyasu is also close. This seems a little bit unjust on Cho U, Hane Naoki and Yamashita Keigo, yet they lose a little bit more this year.

Chang Hao and Ch'oe Cheol-han won the semifinals of the Ing cup with the same score 2:1. Yoda Norimoto won the first game of the Meijin title match against the challenger Cho U.

The first 8 places remained unchanged. Yu Bin and Cho Hun-hyeon returned to the top ten replacing Song T'ae-kon who lost the semifinal of the Ing cup to Chang Hao and Cho Han-seung. Interesting that Yun Chun-sang's good results in the Korean LG cup and Korean Dream league continue. He stays in the first 20. Cho Hye-yeon at 51st is higher in the table than Rui Naiwei (53rd)

Samsung cup was the latest big tournament. Korean and Chinese players had a lot of success, each country having 4 representatives in the quarterfinals. Yi Cha'ng-ho dropped out at early stages. In the Toyota Denso cup the remaining two are Yi Se-tol and Chang Hao. In the Fujitsu cup Pak Yeong-hun beat Yoda Norimoto in the final and became the youngest 9p player ever. In the Chunlan cup the finalists are Zhou Heyang of China and Yi Ch'ang-ho of Korea. In the Ing cup tboth China and Korea have two participants left.

In Korea Yi Ch'ang-ho beat Yi Se-tol in the Wangwi title match 3:2. Cho Hye-yeon won 4 in a row in the BC card cup beating quite strong male players. The most interesting Korean tournament at present is the Korean Dream league with planty of the high profile matches.

In Japan Cho U retained his Honinbo title and Yoda Norimoto defended his Gosei title. Yamashita Keigo is recovering from a slump. He made it to the Oza title match and will play in the challenger's final in Tengen-sen. Chinen Kaori will challenge Kobayashi Izumi in the female Honinbo title match.

The changes in the top ten are quite significant. Cho Hun-hyeon is pushed out by younger players. Wang Xi moved up to 6-th. Though Yi Se-tol lost the Wangwi title match to Yi Ch'ang-ho but that was close. Good performance in other competititions brought him back to the 3rd place. Gu Li continues his impressive run. Korean youngsters complete the top ten. The unexpected player in the top ten is Yun Chung-sang. His success comes from a series of wins in the Korean Dream league. Intersting whether this is an indication of greater success. Yamashita Keigo moved up 11 places. Cho Hye-yeon is 56th at the moment while Rui Naiwei is 48th.

19.06.04

In the quarterfinals of the Fujitsu cup Yoda Norimoto managed to defeat Yi Ch'ang-ho. Yi took revange in the Qinda cup though. After that Yi beat Kong Jie as well.

Yoda Norimoto won half a point in his Kisei league game against Yamashita Keigo, but lost the 4th game of the Hininbo title match. Cho U lost a Meijin league game to Yamashita Keigo and endangered his randez-vous with Yoda in the Meijin title match as Kobayashi Satoru is at 5-2 as well with one match remaining for each.

Changes in the top ten are small. Ch'oe Ch'eol-han lost a game in the fresh 10 tournament and lost his second place to Gu Li. Cho Hun-hyeon won an important game in the looser's section of the KBS cup and moved a little bit up. Mok lost to Pak Yeong-hun in the dream league. On a deep losing streak O Meien moved to 68th. The best of Japanese, Yoda Meijin is 20th.

In two and a half month since the last rating a lot of different things happened. First of all Yi Ch'ang-ho loses match after match to Ch'oe Ch'eol-han. Chinese did very well in the Asia cup. The first tree rounds of the Ing cup determined the semifinalists, two of which come from Korea and two from China.

Yamashita Keigo lost Kisei title and O Rissei defended Judan title.

In the table the highest of the Japanese, Yoda Norimoto, is only 21st. Ch'oe Cheol-han moved to the second place after his successful onslaught on Yi Ch'ang-ho in Kuksu, Kiseong and Ing Cup. Cho Hun-hyeon moved to the ninth place. His curent results are not very good. Yamashita Keigo is 35th at the moment after a streak of 8 loses in a row.

Yamashita Keigo is on a big slump. He loses a game after a game. Mimura Tomoyasu defeated Kobayashi Koichi in the Honinbo league. He moved to the 12th position in the rating table. Last year was rather successful for him. He scored a win against Yi Ch'ang-ho, won the NHK title and is 3:1 in the Honinbo league now.

Qiu Jin is leading in the Mingren title match with 2 wins against one loss. Rui Naiwei started to lose to women. The winner of Jeongganjang Cup is Pak Chi-eun this year.

The changes in the top ten are small. Cho'oe Ch'eol-han moved to the 7th position and Wang Lei dropped two places.

It is interesting that Mimura Tomoyasu moved to the 12th. He has a good run and I'd expect him in some title matches soon. Yamashita Keigo moved to 23rd after one more loss (to O Rissei).

As the new Meijin league starts Yamashita Keigo record in the previous tournament is depreciated. He moved down in the table.

O Rissei managed to kill Kong Jie's group in the Internet China-Japan game and Japan lost by 1 to 4 only.

Cho Hun-hyeon won the Myeongin league to face Yi Ch'ang-ho in the title match, but lost to Yi in the dream league and to Ch'oe Ch'eol-han in the Kiseong. Kobayashi Koichi won Ryusei and scored a win over O Meien in the new Honinbo league.

Yi Ch'ang-ho unexpectedly lost a game to Mimura Tomoyasu in the Asian TV cup. Yu Bin and Qiu Jun do well in the Mingren.

Chang Hao moved to the 22nd. He loses a lot recently.

August was a vecation manth for me. In my absence Yoda Norimoto won the Gosei title. Yi Chang-ho retained Wangwi title. Gu li defeated Song T'ae-kon in the China-Korea tengen match. Kim Chu-ho grew to the fifth place. He is another example of a young and daring my system overestimates. There is only one Japanese in the top ten and there are 4 Chinese players. Kong Jie continues to show impressive results. Gu Li and Wang Lei play wonderfully as well. Song T'ae-kon went down seaching for his proper place as more games mean more losses for him.

Yoda Norimoto won the second game of the Gosei title match. Cho U lost a game in the Kisei league. Song T'ae-kon got into the KBS final. The 5th stage of the Hao Mao cup was without major surprises for the leading players.

I retuned to the simple quadratic fuction to compute the rating, so some of the changes reflect the change of the procedure. These changes are not very significant.

Chinese resumed Hao Mao cup. Almost all favourites won their games. Liu Xing lost though and moved to the 11th in the overal standing. Cho U became the new Honinbo and is back in the top ten. Cho Hun-hyeon lost the first game of the Wangwi title match to Yi Ch'ang-ho and moved a place down. Gu Li is now fifth.

Cho Hye-yeon has four wins in a row in the Korea cup. And She beats young Korean guys, very strong players. She is 76th in the rating now, which is very high for any lady excluding Rui Naiwei.

New Kisei league started with Cho Chikun's win over O Meien. The previous year Kisei league is history now, which affects some players that performed either well or bad in the league.

Yamashita Keigo scored wins in the Meijin league and NEC cup. He is 6:0 in the Meijin league with two rounds to go, yet Cho U and Rin Kaiho keep the pace> Rin Kaiho scored a win against Ryu Shikun and stays at 5:2 and one game to paly. Cho U is 5:1 with 2 games remaining.

Yoda Norimoto goes well in the Honinbo prelims though he lost to Yamashita in the NEC cup.

Song T'ae-kon made it to the final of the winner's half of KBS cup. Yu Ch'ang-hyeok beat Yi Ch'ang-ho in the Paewang final for the second time.

The same playes occupy the first ten places in the rating table, though there were some permutations. Recent loses made Yi Ch'ang-ho's lead smaller.

As China cancelled the games due to SARS the battles in the Korean and Japanese domestic competitions continue. Among the big results in Korea one can mention Yi Se-tol's loss to Song T'ae-kon and Yi Chang-ho's win over Pak Yeong-hun. Mok Chin-seok seems to be back on track.

In Japan Yamahita Keigo lost to Yokota Shigeaki, Cho U defeated Yoda Norimoto. Cho Chikun lost to Kobayashi Satoru.

Cho U lost the first game of the Honibo title match to Kato Masao. Takao Shinji won a game in the first round of Oza. This win brought him back to the top ten while Cho U went a little bit down. One cannot say that Cho U's opponents weak so far as he played in all leagues against the strongest of the Japanese go, but the title matches are tougher perhaps. Song T'ae-kon changes places with Yamashita Keigo. Their ratings are very close and minor disturbances can result in switches.

At the moment there are 3 Japanese players in the top ten. They all belong to the new promicing generation and have to prove their high positions but maintaining good international record.

The main event of the week was Asian cup won by Japan. Japan beat Korea 4:1. Taiwan beat Korea as well. This is a great success for the Japanese based players. No wonder that they moved up in the table.

Takao Shinji failed to qualify for the Kisei league but stays in the top ten despite the loss as all Japanese players advance. After 3 wins in the Asian cup Yoda Norimito returned to the top 20. Currently he is at the 14th spot.

Takao Shinji lost the fifth game of the Judan title to O Rissei. He went down to the tenth place in the table. O Rissei is 34th. Despite the fact that he kept the title his win/loss ratio for the last year is not great at all. He lost too many games to come close to the top ten.

Gu Li plays well in the HaoMao cup. Yu Ch'ang-hyoek has beaten Yi Se-tol in the final of the KT cup.

The main event of the week were the first two rounds of the Fujitsu cup. This time 4 Japanese and for Korean players qualified to the quarterfinals. Chinese players performed badly and thus lost a little as a group in the rating table.

Takao Shjinji won the fourth game of the Judan title match against O Rissei tying the series. The next game will be decisive. Yamashita Keigo beat Cho Chikun and Cho U defeated O Meien in the Meijin league games.

Yi Ch'ang-ho won the Kiseong title again edging Cho Hun-hyeon 3:2 in the title match.

As the result the Japanese players moved up. Cho U, Takao Shinji and Yamashita Keigo occupy places from 6th to 8th.

Cho U won a game against Cho Chikun in the Meijin league. O Rissei has recentlyimproved his results significantly. This weak he has beaten the current leader Rin Kaiho in the Meijin league.

Kim Chu-ho is now at the 8-th place in the top ten. Takao Shinji moved down to the 12th. Kim Chu-ho is the last example of a player with very short but very good record in the database. He is a promising player but his true place will be seen after more clashes with the top.

Gu Li qualified to the Tianyuan title match with Huang Yizhong. Cho U Keigo and O Meien won their next games in the Honinbo league keeping the competition open. Rin Kaiho leads in the Meijin league but the competition there is still very open as Cho Chikun and Yamashita Keigo have all wins as well and Cho U has only one loss.

The changes in the top ten are not significant. Takao Shinji lost a place to Cho U, Gu Li moved one spot up and Pak Yeong-hun is back, both at the expense of Kong Jie.

Yi Se-tol won a KT cup game against Cho Hun-hyeon. He establishes himself firmly as the world number two. Later the same week Yi Se-tol and Yi Chang-ho won a game apiece in the International LG cup.

Cho Chikun won a NHK cup game against Cho U. Despite the change of generations in the Japanese go, Cho Chikun is still a very strong player. He slid down because of the losses in the Meijin and Oza title matches as well as poor result in the Honinbo league, yet he wins a lot of games, which allows him to keep in the second ten.

Yamashita Keigo won Kisei title defeating O Rissei 4:1, yet remains at the 14th spot. Takao Shinji went a step down because of the aging of his results.

Pak_Yeong-hun lost a Paewang game to Rui_Naiwei and Chang Hao lost a TianYuan game to Hu Yaoyu. But Gu Li shows good results.

Obviously, Takao Shinji is not a better player than Cho Hun-hyeon yet, though he moved to the 5th place after winning yet another game against Kobayashi Koichi. Yet, Cho Hun-hyeon loses a lot recently and as long as Takao Shinji continues his winning streak, he will remain at the top. The Judan title match against O Rissei will show who is who.

As the result of his current exploits in the Xinren Wang Kong Jie moved into top ten to the 9th place. Chang Hao dropped out. Despite a new win in the Kisei title match Yamashita Keigo remains 12-th. Song T'ae-kon continues to win and keeps the fourth position.

In China Gu Li and Chang Hao lost semifinals of RIKOH cup to Liu Xing and Kong Jie. This means that Gu Li is now 11th in the table while Chang Hao is tenth. Pak Yeong-hun returned to the top ten and occupies 9-th place.

In Japan Cho U, Yamashita Keigo and Takao Shinji show good results in the leagues while Cho Chikun's loss makes him 1-4 in the Honinbo league, which means demotion. Takao Shinji defeated Yamashita Keigo in the challenger's final of the Judan cup and moved one step higher in the table changing places with Cho U.

Cho U has defeated O Meien in the Honinbo league in a very important game that can be decisive in determining a new challenger for the title match. Yi Chang-ho has won the Kuksu title match and beat Cho Hun-hyeon in the first game of the Kiseong title match. Yamashita Keigo lost the third game of the Kisei-sen to O Rissei.

Yi Chang-ho is first to reach the level of 200 games in the database.

Results of the Japanese selection tournament for the next Fujitsu were added to the database. As the result Cho U has two more losses and Takeo Shinji several wins including that over Cho U. He is a new entry to the top ten. His game againts Yamashita Keigo for the right to challenge O Risei judan should be very interesting.

Cho Hun-hyeon defeated Wang Lei twice in the Samsung cup final yet his recent losses did not allow him to go higher than his opponent in the rating table. Yi Chang-ho wins over Cho Han-seung in the Kiseong title match 2:0.

Cho U lost a Kasukei game to Hane Naoki and went down quite significantly. Yamashita Keigo defeated O Rissei in the first game of Kisei final but this win did not improve his position much as O Rissei had a terrible ratio of wins and losses last year and his rating is not high.

I was much interested in the outcome of Takeo Shinji vs Cho Chikun game in the loser's final of Judan tournament. Takeo Shinji moves up in the rating table fast but to be higher than Cho Chikun he had to win some games againt him. Takeo won this game and will play Yamashita Keigo in the challenger's final. It is possible that after Kisei title match against Yamashita O Rissei will be forced to play Judan title match against him as well. It is possible though that Takeo Sinji will have a try on the title.

Cho U lost a Meijin league game to Rin Kaiho. The first game of the Kuksu title match between Yi Ch'ang-ho and Cho Han-seung ended with Yi's win.

As the result Yi Se-tol went up to the second place, Wang Lei is the third and new Chunwon Song T'ae-kon in the fourth. Gu Li moved above Pak Yeong-hun and Chang Hao returned to the top ten after beating Yu Bin in the RICOH cup quarterfinal.

This defeat put lost two places in the table to him. He is fourth now. Yi Ch'ang-ho had two wins, however, Yu Ch'ang-hyeok has a good winning streak and Yi Se-tol won as well.

Cho Hun-hyeon lives through a very difficult stage of his carrier as the bunch of young players challenge him in the finals of all possible cups. Currently, he lost the challenger's final of the Kuksu to Cho Han-seung 0:2, is tied with Song T'ae-kon 2:2 in the final of the Chunwon title and lost the first game of the Kiseong challenger's final to Yun Chun-sang, 1d. No wonder that he slipped from the second place in the rating table, a spot that belong to him for such a long time.

Cho Chikun lost the Oza title to O Meien and moved down to the 21st place. Cho U continues to win. This week he defeated O Rissei in the Meijin league. Yamashita Keigo lost a Gosei game and is at the 13th spot.

Chang Hao won the Lebaishi cup again beating Yu Bin, who dropped a place moving to 11th and letting Gu Li into the top ten again.

This was a very bad week for Cho Hun_hyeon. He lost the third game of the Chunwon title match to Song T'ae-kon and the first game of the challenger decision match for the Kuksu title to Cho Han-seung. This made him to fall to the sixth place in the rating table. He has never been this low from the start of the rating. On the other hand he defeated Pak Yeong-hun in the Kiseong semifinal pushing the latter to the 9th position.

Cho U won again. This time he defeated Cho Chikun in the Honinbo league. Cho Chikun, however, beat Chang Hao in the China-Japan Agon Hayago match. Cho U remains the second in the table and Cho Chikun is at the ninteenth place.

Hane Naoki defended the Tengen title beating Cho Sonjin 3:0, Cho Chikun tied the Oza title match with O Meien but lost a game in the Honinbo league to Ryu Shikun. Kobayashi Koichi had two wins in the Nong Shim cup but then lost to Hu Yaoyu who collected 3 wins. In Jinagling cup Wang Lei continue to impress winning games after games. Meijin league started with Yamashita Keigo beating Takemiya Masaki.

Kim Meyong-wan entered the top ten by winning a game in the KT cup. He is one of the players with few games in the database but a good record in one of the tournaments that the systems favours very much. Another one is Takao Sinji who moved to 17th place, one place higher than Cho Chikun. Takao has a good run this year and he is a guy to follow. Perhaps, his position in the rating table is a little bit to high (as well and Song Tae-kon's or Kim Myeong-wan's) but the future will show.

Wang Lei moved to the third position. Gu Li dropped to the 11th.

Other interesting events of the week included O Meien's victory over Cho Chikun in the 3rd match of Oza title, Hane Naoki's second win over Cho Sonjin in the Tengen title match, Chang Hao's win over Yu Bin in Lebaishi Cup title match.

He stays at 8th place. After his 0.5 point lost Cho U went to the third below Song T'ae-kon who won again in the BC card cup.

Yamashita Keigo won the winner's final of the Judan cup play off and returned to the top ten. Yu Bin is in the top ten (9th position) or the first time, due to his success in the Lebaishi cup play off and despite a lost to Wang Lei in the Jiangling cup. Wang Lei is currently fifth.

The big event of the week was the quarterfinal stage of the Samsung Cup. This year Chinese are very successful in this tournament. Three Chinese players made to the semifinals and the only Korean survivor was Cho Hun-hyeon. Another big game was Yoda Norimoto's win over Cho Chikun in the Meijin title match.

Song T'ae-kon was 1:1 this week which allowed him to keep the third spot. Cho U made it to the Meijin league and with this win he keeps the second spot even despite the recent loss to Cho Chikun in the final of Agon cup. Yamashita Keigo lost to Cho Sonjin in the Honinbo league and moved down to the 12th place. Pak Yeong-hun defeated Mok Chin-seok in the second round of Kiseong and moved up to the 8th spot.

The main event of the week was the Korea-China-Japan New Stars Cup. China won the tournament beating Japan and two Korean teams. But ratingwise this tournament was a success to the Japanese. They did quite well while their team was not so packed with stars as the Chinese and Korean first teams. This means Japanese young players moved up in the rating and although Cho U did not play in this particular tournament he played the members of the Japanese team a lot during the last several years. As the result he moved yet higher to the second spot. This is not strange as his record in the current cycle of tournaments is impressive 29-6. Song T'ae-kon won two games and lost once. He keeps the third spot at the moment. Yet, as before, his high position is rather a promise than the established fact.

Elsewhere Song T'ae-kon won a game against Kim Chu-ho in the BC card cup. So, he is 3:1 for the week. Cho U beat O Meien which helped him to get to the second spot in the rating. Yi Se-tol won the Fresh best tournament. Cho Chikun beat O Meien in the first game of Oza-sen title match and Rin Kaiho in the Honinbo league. He is bouncing back. Gu Li beat Yi Ch'ang-ho in the Jiangling cup and returned to the top ten. Pak Yeong-hun moved out of the top ten due to poor performance in the New Stars Cup. Wang Lei had another win in the Jiangling cup confirming his leading position among the Chinese.

New Honinbo league started with Cho U's win over Ryu Shikun. The results of the old league lost their values a little. The result is that Cho U moved to the fourth position in the rating. Yamashita Keigo, however, lost a challenger's final game to Cho Sonjin by half a point. Thus, the young generation can't come to the title matches yet. Cho Chikun won the third game of the Meijin title match and remains higher than Yoda in the rating table. Has he started to bounce back from the losses of the last several months?

Cho Hun-hyeon set up a randez-vous with Song T'ae-kon in the Chunwon final. That would be an interesting series from a point of this rating.

While observing Meijin game on IGS some people said to me that "no way Song is number 2" and that "my system picks raising stars". I have to agree that the system picks raising stars. I consider this feature to be interesting because it makes the rating dynamics. During the last year I had Gu Li and Pak Yeon-hun overestimated and followed with interest their games. Now Song T'ae-kon is at the second spot. His Chunwon title game with Cho Hun-hyeon becomes more interesting for me.

Song T'ae-kon continues to win. He is in the final of the Chunwon cup now and if he beats, say, Cho Hun-hyeon there, there is a chance that the king would change. Of course, being the number one player for a long time is a matter of stability, so the future will show.

Yoda's win in the second game of the Meijin title match puts him above Cho Chikun. The later has a very bad spell at the moment. This could mean that he is either going all the way down or will bounce back to the top in the nearest future.

One can clearly see the change of generation in the Japanese go. This new generation is considered less talented, so they are not fast to seize the titles yet the age of the older players shows. Cho U and Yamashita Keigo are now in the leaders of the rating and very probable contenders of the next issues of the big titles. Slowly Takao Shinji reached the rating of the players like Kato Masao, Kobayashi Koichi, Rin Kaiho.

The previous month brought significant changes in the top ten. Yi Ch'ang-ho keeps the first place but the second place unexpectedly went to Song T'ae-kon. This is a new name. He is 2d in Korea and nicknamed as 9 dan killer. Since his record in the database is short his high position in the rating table is a fluctuation. But he has a win over Yi Ch'ang-ho to his credit while with Yi Se-tol he is 1:1. He is a guy to watch.

Two players show magnificent stability during the last several month. They are Wang Lei, Chinese 8d, and Cho U, 7d, playing in Japan. They have the highest rating among Chinese and Japanese, respectively. But with them the win/loss ratio is extremely good with very strong opponents. Cho U is the holder of a minor title only, but I think that at the moment he is the strongest in Japan. Wang Lei takes over Chang Hao as the leader of Chinese.

The second highest among the Japanese players is also young. He is Yamashita Keigo (currently 11th in the table). With 6:2 result in the Meijin league he could not get to the title match though. But I think that my rating shows that he has a great potential to win titles. This applies to Cho U as well.

There are seven Koreans in the top ten. An Cho-yeong recently plays title matches with Yi Ch'ang-ho. And though he looses them but being a runner up in the title match with the worlds number one help keeping the tenth position. Mok Chin-seok on the other hand became less consistent recently and therefore went down to the teen positions. Gu Li is the same story while Yu Bin's record improved.

Rui Naiwei, the strongest female player is currently 76th. She rarely beats top men nowadays while wins over other ladies are not that valuable.

The game of the week was a Jiangling cup clash between Wang Lei and Chang Hao. Having won this match Wang Lei became the first among Chinese and the 6th overall. A man to watch is Wang Ji who makes fast progress to the top but the number of his games in the database is not large. It is difficult to judge yet.

This week was bad for Cho Chikun. After losing a game to Cho Sonjin in the Kisei league he left the top ten. The tenth spot now belongs to Pak Yeong-hun. Cho U continues to win and move upward in the table. Ch'oe Ch'eol-han lost and went down two places.

The week was bad for master Yoda and Mok Chin-seok. As the result Yoda dropped out from the top 10 and Mok lost one place to Chang Hao. Cho U is a newcomer to the top ten. His standing compared to other players improves slowly but very steady. It is interesting to note that there is a slight trend to replace the top Japanese players with new generation. Cho U, Yamashita Keigo, Yuki Satoshi are steadily going up and though they cannot boast many titles yet but their average performance is better than the results of some of the title holders.

Wang Lei continues to win and keep his position in to ten. Ch'oe Ch'eol-han kept his place too, but for him, so far it is a fluctuation to be proven yet.

Two Japanese players with the highest rating lost last week. Cho Chikun lost a Meiin league match to Yamashita Keigo and Yoda lost an opening Kisei league match to Ryu Shikun. As the result Yoda dropped of the top ten. Another interesting match of the weak was the third game in the Honinbo title match won by Kato Masao this time.

In the Jiangling league in China Gu Li continues to lose and go down in the table while Wang Lei wins and comes closer to Chang Hao, the highest among the Chinese.

As for the Koreans, Yu seems to increase his lead over Cho Hun-heyon in the fight for the second spot. It is interesting that An Cho-yeong is the tenth in the table and yet he has negative win/loss difference. The reason is that most losses were incurred to him two years ago while his recent results are rather impressive.

A sudden change in the top ten with Japanese going up and Chinese down needs some explanation. The players in the range from 7th to 19th place have very close ratings and their position changes by a place or two after each win or loss. At the same time relative positions of the players of different countries are affected most by the international tournaments. Last week Hane Naoki beat Huang Yizhong twice in the China-Japan Tengen competition. This result plus O Meien's win over Pak Hyeon-hun in the quarterfinal of the Fujitsu Cup brought Japanese players to the top of this compact pool.

Kobayashi Satoru lost at last. But a loss to Yi Chang-ho in the quarterfinal of the Fujitsu Cup did not affect his rating much.

Another important factor that determines standing in the top ten is the performance of very young Korean stars. At the moment several young players played to few games to determine there positions with some precision. At the same time they have good wins under their belts. Ch'oe Che'ol-han raised to the seventh spot due to a win over a newbie to the pro world.

Yu Ch'ang-hyeok and Cho Hun-hyeon are very close to each other and change places frequently.

Gu Li dropped from the top ten for the first time, not because of poor performance this particular week but because his excellent last year results become history. Cho Hun-hyeon is back at the second place and Chang Hao is now the leader among Chinese.

Lower in the table Kobayashi Satoru is at the 11th spot. His record for the current year in the database is 8-0, while according to the Nihon Kiin homepage his real life record for this year was 15 wins, no losses last time the page was updated. Quite a return.

Mok Chin-seok loses a lot recently and dropped in the table a little. Kobayashi Satoru dropped back a little as one of his game became dated.

The difference of rating in closer to the tenth place is not large and the players change places often.

Cho Chikun lost to Sonoda in the Gosei semifinals and went even further down in the table. Kobayashi Satoru is moving up fast though. After his return from the exile he has 9 wins with 1 loss in the database. Perhaps, he loses in other competitions but in the competitions on which this rating is based he entered the top ten.

Each round of the Jiangling Cup adds a lot of games between Chinese players and their ratings become more reliable.

Asian TV cup was a Korean matter with Yi Ch'ang-ho winning again.

Yi Se-tol lost a game to a new Korean kid Hyeo. Cho Chikun is now 5:0 in the Meijin league while Yamashita Keigo lost to O Meien. Jiangling cup was the major contributor to the changes in the ranking of Chinese players.

Pak Yeong-hun not only performed well in the Fujitsu cup. He has also beaten Yu Cha'ng-hyeok. This allowed him to get closer to the top 5 Korean players.

Seo Neung-uk went down but not because of a loss but because the start of a new Kiseong league depreciated his old results.

The battle between Cho and Yu in the LG cup final, though fierce did not change much the high standing of both opponents.

As the result Japanese players moved in their bulk moved from the second to the third ten. Yoda moved down to the seventh place and both Cho Chikun and Kato Masao left the top 10.

This was the week of surprising results from China. New Mingren started with early exits of the favourites (Chang Hao, Gu Li, new Tianyuan Huang Yizhong). Thus everything is in a state of confusion in Chinese kingdom and till the new heros rise the old guard lost their high positions in the rating.

Master Yoda could not get the third place this week. He won the NEC final game against O Rissei but quickly lost afterwards, so could move only one place up. Other Japanese players moved up because the Chinese leaders failed. Kato Masao and Cho Chikun, however, had very important wins in Hobinbo and Meijin leagues, respectively. Kato is now 5-1 and Cho 4-0 in "their" leagues. Intersting to note, though that they both do not so good in the "other's" league.

Yu Ch'ang-hyeok lost in Paewang and Cho Hun-hyeo beat Mok Chin-seok in the new Wangwi league. This helps Yoda to keep the fourth place.

An Yeong-kil, though, lost a Paewang game. His rating suffered also from the fact that a new Wangwi league started and the old one, where he performed excellently is depreciated.

After retaining Kisei title O Rissei is the third among Japan based players at fourteenth. He used to be the highest of the Japanese last summer but a crushing defeat at hands of Cho Chikun in Oza title matched spoiled his rating.

Yoda continues to win and Cho Chikun continues to lose. Yu Ch'ang-hyeok and Yi Se-tol changed places.

A good winning streak for Yoda Norimoto. He moved to the 9-th place. Seo Neung-uk lost a game in KT cup, a competition that gave major contribution to his high position, and dropped out of the top ten.

Chinese qualifications to Toyota-Denso Cup was the competition that effected most the top ten. Gu Li and Kong Jie failed to qualify. As the result Gu Li lost his third position to Yi Se-tol and Kong Jie is now 16-th. Yu Ch'ang-hyeok continue to win in Paewang. O Rissei won the first game of the Kisei title match. Before the Oza title match he was the most highly placed among the Japan based players, but a crushing defeat from Cho Chikun forced him into the middle of the second ten. Victories in Kisei match could mean his return to the top ten club.

Ma Xiaochun won Mingren title 13-th time in a row after a victory over Chang Hao (3:2). This brought Chang Hao down one place in the top ten. Ma did not make top 20 though. He can win games but he loses a lot too.

New Myeongin league started and thus all results of the previous league lost value. This effected mainly Cho Hun-hyeon and Yu Ch'ang-hyeok, whose last league performances were excellent.

Yu Ch'ang-hyeok is back to his winning habits. Cho Chikun won another one but for Kato Masao it was a bad week.

The great winners of the week were Yi Ch'ang-ho (Myeongin title) and Hane Naoki (Tengen). Cho Chikun, O Rissei, Kobayashi Koichi, Yoda Norimoto won their games as well.

One change in the top ten. Cho Chikun moved higher than Yu Ch'ang-hyeok. Hane Naoki moved up to 20th place. O Rissei is now the second among Japanese, higher than Kato Masao.

2.12.01

No chamges in the top ten during this week. The main competitions were Nong Shim cup, Chunwon and Tengen finals. Yu Ch'ang-hyeok lost another game. He's having a bad spell. Still, he holds 8th position. Pak Yeong-hun's win in the third Chunwon game is not confirmed yet - the sgf file of the game record shows that he hold black.

25.11.01

The week was good for Gu Li and Kong Jie that made a final pair of RIKOH cup. Cho Chikun scored two wins. Yi Ch'ang-ho beat Yi Se-Tol in the the KBS title games.

The week was bad for Pak Yeong-hun (two losses) and O Rissei who seems to lose his form.

As the result Pak Yeong-hun moved to 12th place, out of the top ten. His previous high position might have been a fluctuation.

Top ten consists of 6 Koreans, 3 Chinese and 1 Japonese.

18.11.01

This week was awful for Yu Ch'ang-hyeok (Korea, 9d) and very good for Seo Neung-uk (9d). The latter won their game in the second round of KT cup. He defeated Yi Ch'ang-ho in the first round of the competition. His other game this week was won as well which allowed him to move to the third spot. This result can be a fluctuation because the number of Seo's games in the databease is not large.

Yu Ch'ang-hyeok moved to the ninth place. Very low for him.

Cho Chikun won a title beating O Rissei 3:0 and moved to the 10th place, higher than other representatives of the Japanese go. O Rissei's win in the last year Oza match became devaluated, so he dropped down strongly.

Top ten consists of 7 Koreans, 2 Chinese and 1 Japonese.

11.11.01

The algorithm of rating calculations was improved. Now the game term in the evaluation function saturates for large differences in opponents' ratings. With this change stronger players are not punished for playing weaker opponents if they win. Look at description of the system for details.

As expected the ratings of strong players with many games (some of which were with much weaker opponents) increased. Yi Ch'ang-ho remained at the top and his teacher moved into clear second position. Gu Li went down several places.

On the battle field, however, a significant event was Yi Ch'ang-ho's loss of mini-match to Chang Hao, who moved into fourth position as the result. Cho Chikun missed his opportunity to move into top ten losing a Kisei play-off game to Ryu Shikun.

Some older results were added to the database. They don't effect positions of leaders much because of the aging, but they contribute to the reliability of standing of the players in the middle of the table.

4.11.01

The last week was a week of important games. Yoda Meijin retained the title, Cho Chikun won the second match of Oza title match, Pak Yeong-hun won the first game of Chunwon final.

I have changed almost all Korean names to McCune-Reischauer form. About 40 duplicate names were eliminated. For the Koreans playing is Japan the spelling was not changed.

During this process a serious mistake was found in the data. The record of one of the Cho_Chikun games with Ryu Shikun by mistake stated that Cho won with 20 stone handicap. Correction of this mistake brought Cho several spots down in the table. But his recent wins over O Rissei brought the latter down too. Now the highest place among the Japanese belongs to Kato Masao who won a Honinbo league game this week. He remains the only representative of Japan in the top ten in company with 2 Chinese and 7 Koreans.

Seo Neung-uk (9d, Korea) jumped in the top ten. Strangely the database does not contain many of his games, otherwise his results are very good and he is a contender for the second spot judging from his raw rating. Of course the question if his record in the database is representative of his level of play remains.

28.10.01

For some games in the database the colour was not known. A new column was added to show the performance of the players in those games. 

LG cup quarterfinals was the major event of the week. Now it is all-Korean affair. A win for Cho Hun-hyeon moved him to the third spot in the table. 

Kobayashi Koichi is back in the  top 20. 

21.10.01

It took me almost half a year to enter all results from the http://www.kyoto.zaq.ne.jp/momoyama/news/news.html

web page in small portions. This is the first time I publish the results though I had a privilege to observe how they change as tournament after tournament was added. 

Yi Ch'ang-ho. There is no doubt about who is the strongest. 

The next to spot came as a surprise. But these are young people to watch. They don't have many games in the database and hopefully the data are representative. Gu Li and Park Yunghun did well is several tournaments but they did not play other players from the top 20 very often, though both have celebrities among their victims. 

 The next 3 places for Korean top players are not strange and the order is dynamic, depending on the current success or failure. 

Cho Chikun is still the highest among Japanese despite the loss of all his major titles. His record in the lightning games remains good and a win in the last week Oza match contributed. 

O Rissei is the second representative of Japan. Nothing strange in it. 

Chang Hao is the best among Chinese if one considers Gu Li phenomenon more as a promise.

Kato Masao did not win any major titles recently but his performance is incredibly consistent. He does not lose at early stages of the tournaments as a rule and performs well in leagues. 

The second 10 are close to each other. Their relative positions are dynamic. 

Ma Xiaochun was a disappointment. His record was not that good last 2 years. Thus only 24th.

Rui Naiwei was the biggest disappointment. He win/loss ratio is great but most wins were against other ladies. Her recent performance against men was not good and thus only 54th spot.
