Takemiya Masaki (9Pro Dan): This is Go the Natural Way !

British Go Journal (Winter 1990)

British Go Journal (Winter 1990)

Long time ago, between 1983 and 1991 the Japanese Go Professional Takemiya Masaki (9p D) wrote for the British Go Journal (BGJ) about different topics, as the table shows (see bottom). The articles originally had been published in Kido Magazine which was for many years the Nihon Ki-in’s dan-level go magazine till 2000.

From 1988 on Takemiya presented in the BGJ different problems of Fuseki-s (openings) within the series “This is Go the Natural Way !” – naturally related to SanRenSei.

Three interesting problems Takemiya presented in part 7, being published in edition No. 81 of the British Go Journal (Winter 1990), as you can read in the PDF (free download here).

If you like to read the whole series, best you buy the book with same title which was published in 2008. “This is Go the Natural Way!“are the watchwords that the author takes as his philosophy of play in this unique volume, but the book could also be viewed as The Best Games of Takemiya Masaki.

yellow mountain imports sold this book originally published by Hinoki Press in the past at a reduced prize of 17.99 US dollars (original prize: 20.00 US$). There it is no more available. It might be a challenge to get one original print nowadays (ISBN 13 978-0-9788874-9-0).

yellow-mountain-importsWhen Takemiya published the material that has been translated by Bob Terry, he was Honinbo and at the top of his form. Few professional go players were serious rivals for him. And the ones who were are today considered as great players in the same way as he is, such as Cho Chikun, Kato Masao or Sakata Eio. All of these players and many more make appearances in this volume.

The twelve games covered (the list gives the White player first) are:

  1. Takemiya Masaki – Hashimoto Utaro, 1972-08-08, All Japan No. 1 Tournament
  2. Kato Masao – Takemiya Masaki, 1974-05-18/19, Honinbo League
  3. Takemiya Masaki – Rin Kaiho, 1974-03-28, Pro Best Ten Final
  4. Takemiya Masaki – Abe Yoshiteru, 1977-10-06, Oteai
  5. Ishida Yoshio – Takemiya Masaki, 1970-12-20/21, Nihon Ki-in Championship
  6. Hashimoto Shoji – Takemiya Masaki, 1969-05-22, Pro Best Ten
  7. Ishida Yoshio – Takemiya Masaki, 1974-03-03, Nihon Ki-in Championship
  8. Yamabe Toshiro – Takemiya Masaki, 1970-06-04, Nihon Ki-in Championship
  9. Ishida Yoshio – Takemiya Masaki, 1974-03-30/31, Honinbo Title Match, Game 2
  10. Takemiya Masaki – Rin Kaiho, 1974-01-23/24, Honinbo
  11. Takemiya Masaki – Honda Kunahisa, 1974-01-14, Meijin League
  12. Takemiya Masaki – Cho Chikun, 1981-05-26, Honinbo Title Match, Game 1

This is not merely a collection of brilliant games. Far from it. In fact, several of the games analyzed in this book ended in losses for the author. But that is not the key factor that Takemiya takes pains to explain. The laws were not in his strategy, but in the execution, and at critical points more experienced players edged him out for wins. Such as when Ishida Yoshio defeated Takemiya (4-3) in the 1974 Honinbo Title Match. One of Takemiya’s greatest games appeared in that match, but he ended up losing it and the match. He won the title two years later, but he would rather dwell on that earlier loss than recount the triumph that followed. The reader should examine that game published here.

Famous Go games: 1582 – 1959 (overview)

Tks to toomtam (c/o Go Association of Thailand) for this list he sticked together on 21st April 2001. Probably its not complete, but for a beginner like I am it gives some orientation how Go developed over centuries. Interesting to see the over dominance of Go Seigen (1914-30th Nov 2014) in 20th century. – What game do you know ?

Honinbo_Dosaku   Honinbo_Jowa   shunsaku
[f.l.t.r.:  Honinbo Dosaku (1645-1702), Honinbo Jowa (1787-1847), Honinbo Shusaku (1829-1862) ]

A more detailled and complete overview you might find on SL :  http://senseis.xmp.net/?FamousGoGames (latest edit: 1st April 2014).

Overview of famous games: 1582 – 1959

Year: White x Black; 
     Result; Why is it well-known?

1582: Nikkai, Honinbo Sansa x Kashio Rigen
tripple ko; at night after the game the emperor Nobunaga was killed. Since then the tripple ko is a bad sign. In the kifu there is no tripple ko, it is incomplete.

1625: Nakamura Doseki x Yasui Santetsu
W+; first move was on the side

1682: Honinbo Dosaku (Meijin) x Peichin Hamahika (4handicap)
W+14; first official international match, Peichin visited Japan, but he was crushed by the go-saint in four handicap

1683: Honinbo Dosaku (Meijin) x Yasui Shunchi (or Sanchi) (2handicap)
B+1; Dosaku’s masterpiece – 2 handicap lost by one point. Today’s professionals say that the fuseki is aged, that today even amateurs would play it better, but in the middle game Shunchi played a sequence of excellent moves. How Dosaku was able to catch up to 1 point difference is nearly incomparable.

see “Review by 1PD Francis Meyer” of 17th century game (Edo period)
with Honinbo Dosaku and Yasui Chitetsu

1705: Yasui Senkaku x Honinbo Dochi
B+1; Dochi’s surprising endgame tesuji brought him 2 points and win

1792: Yasui Senchi Senkaku x Honinbo Retsugen
W+R; Senkaku’s style – influence, Senkaku turned the game around with the fight

1812: Honinbo Genjo x Nakano Chitoku (Yasui Senchi)
B+R; move 69 looks nearly like a pass

1815: Honinbo Jowa x Hattori Rittetsu (Gennan Inseki)
B+4; masterpiece of Gennan against his irreconcilable rival

1820: Yasui Senchi x Honinbo Jowa
B+2; marked as the best game of Edo period although black kept the advantage of the first move and won by two points, Senchi’s amashi strategy is praised a lot

1835: Honinbo Jowa (Meijin) x Akaboshi Intetsu
W+R; blood-vomiting game. Jowa, who as a Meijin couldn’t afford to lose, had to face new secret trick joseki (move 33), that gave Akaboshi advantage. But Jowa then played three brilliant tesuji (68, 70,
80) and turned the game around. After a week of playing Intetsu kolapsed, started to vomit blood, and died in a few days.

1842: Inoue Genan Inseki x Honinbo Shuwa
B+6; the match of two players, who had the strength of a Meijin, but didn’t become Meijin. Jowa commented that Gennan was strong enough to become a Meijin but he was unfortunately born in a wrong time. In endgame Gennan was losing by one point, so he tried to live in the corner, but didn’t manage to do it and the difference raised to 6 points.

1844: Honinbo Shuwa x Yasui Sanchi
B+1; move 63 is a very strange shape, it is nobi where you wouldn’t expect it

1846: Inoue Genan Inseki x Kuwahara Shusaku
B+3; ear-redding game, legendary move 127 just next to tengen, with which Shusaku surprised Gennan as well as onlookers and reversed unfavourable game

1851: Honinbo Shuwa x Honinbo Shusaku
B+4; well-known for fans of “Hikaru no Go“, the first game between Touya Akira and Shindo Hikaru (Sai)

1852: Honinbo Shusaku x Ito Showa
W+R; confrontation of two generations, Shusaku (22) with white defeated Showa (50)

1853: Honinbo Shusaku x Ota Yuzo
W+3; with this game Shusaku forced Yuzo to handicap and won the most famous match of Edo period. Slow, but thick move 88 says: “Just this is enough to win”.

1895: Honinbo Shuei x Tamamura Hoju (Honinbo Shusai)
W+2; the move 92 is well-known tesuji with escaping to geta, which saves white stones

1926: Honinbo Shusai (Meijin) x Karigane Junichi
W+T; Kiseisha vs Nihon Ki-in, one of the most difficult games in history, very fighting and effective game (70 move semeai, etc.), it was demonstrated on huge boardsin Tokyo gardens, and cotributed to popularization of go.

1929: Kitani Minoru x Go Seigen
W+3; Go Seigen plays mirror go to move 65, Kitani plays surprising tesuji 114

1933: Go Seigen x Kosugi Tei
W+R; famous “16 soldiers” in style of new fuseki, Go absolutely crashed his opponent using his influence and attacking all groups

a mathematical approach with video animation and kifu (SGF) here.

1934: Honinbo Shusai (Meijin) x Go Seigen
W+2; “the game of a century”, Go plays new fuseki; diagonal sansan, tengen, hoshi; Meijin turned the game around with tesuji 160

1938: Honinbo Shusai (Meijin) x Kitani Minoru
B+5; the last game of Shusai, interesting because Jasunari Kawabate wrote a novel “Meijin” full of excitement about passing away of an old master

1939: Go Seigen x Kitani Minoru
W+2; first game from the most famous match of a new era (Kamamura jubango) between authors of new fuseki; Kitani started bleeding at move 128

see video lecture by Michael Redmond (9Pdan) in Sept 2014
of 1st game from Kamakura Jubango (1939-1941)

1945: Hashimoto Utaro x Iwamoto Kaoru (known as the Atomic Bomb Game)
W+5; the game was played near Hiroshima, when the atom bomb exploded (it was between moves 126 and 127), the position was destroyed but players assembled it again and continued playing

1948: Go Seigen x Iwamoto Kaoru
W+1(2); after the game there was an argue whether black has to fill in a ko when he has more threats

Large avalanche

Large avalanche Joseki (Source: SL)

1951: Go Seigen x Fujisawa Hosai
W+R; first match of two 9 dans in history

1957: Go Seigen x Kitani Minoru
W+R; encounter of two eternal rivals after 13 years brought excellent fight, often quoted game

1957a: Takagawa Kaku x Go Seigen 1)
B+R; Go Seigen played the big avalanche (joseki)

1959: Go Seigen x Takagawa Kaku (Honinbo Shukaku)
B+0.5; a ko dispute, white had more threats but had to connect anyway

1) … next days I will post a Kifu of this game we will see that white (Takagawa) played SanRenSei as answer to Go Seigen’s “Big (large) Avalance” (joseki).

New browser based GO Server online: LankeWeiqi 2.0 is up (Chinese, Japanese, English)

New Online Go Server appears behind the horizon…


All infos I got for now from the developer team that three enthusiastic Go players worked on programming a new GO server. A complete new version 2.0 is up since today (2nd Dec).

It is called LankeWeiqi or as short form LKGS (Lanke Go Server).
Similar to OGS (Online Go Server) which is owned by two software developers in the USA (matburt and anoek) following a merger with nova.gs in October 2013 the new Go server LankeWeiqi seems to be owned by the company Xining Vidoo Information & Technology Co. Ltd. and is purely web-browser based (without Java).

So another “…GS name” in the market of Online GO Servers beside the existing (e.g. OGS – Online Go Server, Pandanet-IGS, DGS – Dragon GO Server, KGS etc. …) ?? – For pure beginners this landscape might become little bit confusing. 🙂

These days this very new server with a .cc domain (registrated on Cokos (Keeling) Islands/Australia) is accessable and simply to surf via web browser (on my own I only did a test with Google Chrome). No extra desktop client must be downloaded as we know it from Wbaduk, Tygem and Pandanet-IGS (and best to do so with KGS). For now LKGS mainly is available with it’s front end in Chinese language. – The English version is being translated these days and up very soon so I was told today. Another language this server will be available is Japanese.

It is very teachable for Non Asians to learn the fighting oriented Asian style and visit specific Online Go servers herefor. This new Go server LKGS gives hope that Go players from Western world get the chance to meet Asian players as we know it from Tygem, Wbaduk and Pandanet-IGS but have a more direct inter-action, e.g. English based Chat communication (Rec.: On Wbaduk and Tygem mainly play Asians from Korea and China with very few Japanese and a regular English communication isnt possible for 95% of all games (by my own experience).)

The look and feel of the LKGS ENG frontpage (without login) for now:  http://lanke.cc/homeen.html


After registration and login which worked within seconds giving a uniquly User name, Nick name and password here the look and feel of the central menu, with the chat room (botttom left), games list (top left) and players overview (right side):


Some more features are “Class room“, “Discussion Group“, Club, “Go News” and a link to the  Quing Hai Go Association (Rec.: Qinghai Province is the fourth largest province in China.).  Some other features might be interesting too, e.g. Team Ranking lists.

Here two screenshots of the game pages, one still running, another just finished:


Screenshot-match2-1If you want give it a try on your own and you should not be confident with Chinese (as I am) use the “Translate to English” function of your browser (e.g. available in Google Chrome). It will show you following: http://www.lanke.cc/pages/userReg.html


(Rec.: Similar to OGS for registrating on LKGS there is not needed an email addess for completing the registration process (which I see it as critically if you should forget the password or the account should be hacked.))

You can find me on LKGS with same user name as you know me on most other online GO Servers (e.g. KGS, Tygem, Wbaduk, IGS and OGS): LinuxGooo .

Four San-RenSei Games as white – Can w win with Cosmic Style ?

Can White win with San-RenSei / Cosmic Style ?

… in tendency exists the opinion about San-RenSei that it is mainly an opening for black, and the chances for playing this fuseki as white to win are very low.

I dont agree totally… as I play San-RenSei – as black and as white. Being one stone behind as white makes it (little bit more) difficult to realize a SRS fuseki and placing the centre stone first to claim the big centre-oriented moyo. But its possible.. and I take it as challenge… and as a training wheel to play under difficult conditions.

Here four (4) games with San-RenSei I played shortly as white (10kyu) on OGS with following opponents:

1.) 2014-10-17… [Satomi][1], 11k… w+res
2.) 2014-10-20… [awe][2] (aka wow), 12k… w+19.5
3.) 2014-10-25… [brykim1][3], 16k… w+res
4.) 2014-11-06… [LeandroSilva][4], 16k… w+43.5

Tks to all opponents… more important than winning a game is to learn from, as it shows own weaknesses, risky situations and what has been missed to play for avoiding a loss.

Take yourself a view at if you like to learn more about San-RenSei:

1.) 2014-10-17: LinuxGooo (10k) vs. Satomi (11k)… w+res

Narrow fights and aggressive attacks as black did already with 3rd move on C14 instead first complete own Chinese fuseki on right sight very often self damaging. In Go first counts safetyness and to secure the living of own stones… greedyness is punished in GO as quickly its about fighting for own surviving ( own review as SGS here: Eidogo | OGS ).

2.) 2014-10-20: LinuxGooo (10k) vs. awe aka wow (12k)… w+19.5

I havent thought to win after black attacked left side… pushed white upwards with a wall on G8-G10. Black’s jump on J13 was little bit risky which allowed white to sneak in via G11. Shapes can only being played for specific situations, the knight move has its own weakness as we can see in this situation (see keima = small knight jump: http://senseis.xmp.net/?Keima and ogeima = large knight move: http://senseis.xmp.net/?LargeKnightsMove ).
Black’s tigre mouth D8-E9-E7 (another shape) I felt was insane and a hard attack… black missed to connect via D7 which gave white the chance for a huge left side. Black took many little risks in this game which was no urgent need. So black pushed himself into own weaknesses…

3.) 2014-10-25: LinuxGooo (10k) vs. brykim1 (16k)… w+res

The loss for black is simple to explain: Missing a group with two living eyes… running, running, running over the whole board (F3 – P5)… and then dying with white’s move 154 (J7) the chance for 2nd eye was destroyed. Too many weak groups and constantly playing in gote are often the reason to loose a game.

For your individual Go training pick up the SGF here:  Eidogo | OGS

4.) 2014-11-06: LinuxGooo (10k) vs. LeandroSilva (16k)… w+43.5

Black missed to recognize by time that white plays San-RenSei/Cosmic Style… and therefore didnt take care for the right timing to invade via its stone on M12 into white’s moyo. Two other mistakes supported white to expand into a huge moyo: (A) playing too defensive on right side which gave white a big inside wall Q4-Q7 – (B) Black focussed on bottom left corner with move 57 (D3) instead pushing white back on G4…

11/03/2014 (San-RenSei review): Can white survive inside black’s big moyo ? (Wbaduk)

… just back from Wbaduk playing there as black against an opponent of equal level (both rank 11k).

Its an interesting San-RenSei game as it looks on first view, that white managed it to split black’s left and top side with E14 and E15… but white had to survive inside black’s big moyo with two tiny small groups binding all its energy to survive there, while black herewith got a big wall with a huge territory area on right side. White was isolated by black’s strong base on bottom side.

White gave up at move 241. – Here it goes… 🙂

01/11/2014: an interesting SRS game between 1K (b) and 1D (w)

… as mentioned (see first posting in the category SanRenSei Games) you can collect and share on this blog SanRenSei/Cosmic Style (oriented) games which have been played on OGS or other GO Servers (e.g. KGS, Wbaduk; Tygem, IGS, DGS etcc …).

Tks to lemmata (2D player on OGS) informing me about another interesting SRS game I jumped in yesterday (11/01/2014) lurking… the result: b+timeout

1044024-203-usc-goodattack.sgf (2.0 KB)

The game was played between 1K (goodattack) and 1D (usc). Goodattack as black started with SRS on right side, untypically answered white’s attack on top corner with direct attaching on O16. Securing the corner via Q17 usc as white got the chance to occupy top side via K17… which stopped black to play own 4th Star point on K16.

Black instead expanded the left wing side of its base typically as written in the SRS books. Unusually black liked to cut white’s knight jump R12 – P11 instead playing straight P10 to protect own big moyo. In following white succeed to get a strong inside base B11-P8 plus occupying the centre with stone L9. Normally black should have avoid this under any circumsstances.

Black won by time out… regularly would have lost the game as white even destroyed black’s option on left side to build a 2nd eye around F9.

For your individual Go training pick up the SGF here:  Eidogo | OGS

(3) Round 3 (3rd game)… black shows some weaknesses on top side but very strong bottom side without playing O10 same white played aside D11 instead of D10 ([see also Ni-RenSei][4])

Seeking Balance in Harmony – Gu Li on the Three Star Opening (Sanrensei)

Gu-Li-fights-back-3rd-BC-Card-Cup-final-match-4There are many popular openings in today’s go world. Living Go legend Gu Li (9P) likes to use openings that have been popular in the past that aren’t used that often today. After some examination, he selected the three star opening, which matches his style in the 1st decade of 21st century.

A Modern Three Star Opening

Gu Li’s version of the three star opening is different from that of the famous Japanese player Takemiya’s “Cosmic Style”. Takemiya uses the three stars to create a moyo-type opening, whereas Gu Li’s style pays attention to both thickness and territory, creating a balance in harmony.

Double SanRenSei game (14th-21st Oct 2014) … w+19.5

Here a “double SanRenSei” match which had been played as correspondence game over seven (7) days (from 14th till 21st Oct) with the result w+19.5

Tks to wow (12k) for challenging me on 10th Oct. It was an interesting game as we both are SanRenSei / Cosmic style players (or less, try to become one in farer future). From beginning it was clear, that we both will open with classical SanRenSei star point fuseki.

Rec.: In tendency it is said, that playing SanRenSei as white against black as SRS then white can’t win the game as black can position first the “centrer stone” (mostly asymetric one coordinate beside K10/Tengen), same as it happened in the game black claimed its big moyo playing first on L10.

With the analysis of a bigger game database, e.g. Fuseki.info (Total number of games in database where both players are professionals: 78,476 / status: 21st Oct 2014)… during first ten (10) moves the statistics for white to win the game decrease to 40%.


Here the game: Black’s attack onto left side was tough as it pushed up white with a wall on G8-G10. Luckily white got the chance to block and to sneak in via G11 as black decided for a “large knight move” up to J13 instead H12.

In the endgame black missed to cut white playing simply P8 instead of M18, which gave white the chance to break through to right side. It was costly for black and gave white 10 points.

SanRenSei game (3rd round… CODECENTRIC Go Challenge 2014): Go bot CrazyStone (5-6D) vs. Franz-Josef Dickhut (6D)

codecentric go challenge 2014 (with total score of best-of-five competition)

Today we have seen an impressive, 3rd game with a very classical SanRenSei opening between 11 times National GO Champion Franz-Josef Dickhut (6Dan EGF) from Germany as white and the Go bot CrazyStone (5-6D) as black. This bot runs on a server with low capacity Dual Core 900 mhz processor.

1911f5428f83e623e2c5e1ba438344533e5413367234   191352331174edd3981e1d05f05fbe94118f9d53d08c

How did it make Franz-Josef to survive after his centre attack ? – With move 70 white still missed a 2nd eye to survive there.

Today this game has been re-streamed on OGS live from KGS. – Tks to the KGS team and tks to Remi Coloum for programming CrazyStone which is available for Windows PCs (buy it here). – And congrats to Franz-Josef for his fantastic game (and win) we have seen today taking all four courners and an exiting Ko fight which might have isolated white’s centre group.

status quo on 18th Oct 2014: Crazy Stone – Franz-Josef Dickhut: 1-2

– 10/04/2014: Crazy Stone wins by 1,5 points
– 10/11/2014: Franz-Josef Dickhut wins by resignation
– 10/18/2014: Franz-Josef Dickhut wins by resignation


Go is Asia’s most popular board game with many professional players in Japan, Korea, China and Taiwan. From the programmer’s perspective, go is also one of the most complex games. In chess, the program “Deep Blue” beat then human world champion Garry Kasparov as early as 1997. However, even the best go programs of today are still significantly weaker than professional go players.

But the gap is closing. In the last couple of years, the playing strength of go programs has leaped to a new level. This was due mainly to the incorporation of Monte Carlo methods into the traditional game tree search approach. Yet up to now, no professional or top amateur has played against a go program in an even contest, i.e. without a handicap of several stones in favor of the program.

Cuba-Mexico Tournament 2014…

Cuban and Mexican Kids Get Together for Go in Havana
(original published on Friday, 25 April 2014 09:18)

Cuba and Mexico held their first primary school go exchange this April at the Cuban Go Academy in the Eduardo Saborit Sports Complex in Havana. Five Mexican and seven Cuban primary shool students competed in a four-round Swiss System on the 14th and 15th (Monday and Tuesday), also finding time for a game of soccer on Monday and a beach house visit on Tuesday. Then after an instructional class, game commentaries, and a social event, the exchange concluded with a 13 x 13 pair go tournament on April 18 (Friday) in which the Mexicans took Cuban partners. The individual Swiss System, which made the Tuesday sports news on Cuban TV, was won by Carlos Manuel Alfonso Basabe (Cuba, age 9) while Diego Armando Luciano Cortes (Mexico, age 7) finished second. In the pair competition, Carlos teamed up with Daniela Luciano Cortes (Mexico, age 9) to take first place. The entire event appeared on Cuban TV again when sports commentator Yimmy Castillo covered it in his Sunday Pulso Deportivo (Sports Pulse) program.

Participants at the 2014 Cuba-Mexico primary school go exchange.

The Mexican players were accompanied by parents and by Siddhartha Avila (Program Director, Mexican Youth Go Community / Univ. of Michigan The Cultural Ambassador Go Program / GCAIP co-founder from Pipiolo Elementary School), who teaches go to primary school children in Mexico. During the five days, these grown-ups and their Cuban counterparts discussed topics of mutual interest, such as the educational systems in the two countries and methods of teaching go. The exchange grew out of a 2013 visit to Cuba by go players from the United States, who then met Siddhartha at the 2013 U.S. Go Congress and told him about the **Cuban Go Academy’s program for children of primary-school age**. Siddhartha contacted the Cubans, and the idea of an exchange was born. In organizing the exchange, the Cuban Go Academy obtained support from the Mexican ‘Pipiolo’ Center for Primary School Educational and Artistic Research, as well as from Cuba’s National Institute for Sports, Physical Education and Recreation (INDER) and from Cubadeportes (Cuba Sports).
This go exchange was the first of its kind in Latin America, and the organizers described it as a great success. In future years the Cuban Go Academy hopes to expand it to include more Latin American countries where go is taught to children. In the more immediate future, they are preparing for a ten-day visit in May by twenty Spanish-speaking Japanese players representing Japan’s Sociedad de Intercambio Internacional de Go (Society for International Go Exchange), and in the more distant future, they dream of holding a World Amateur Go Championship in Havana.

First Correspondence Game with SanRenSei finished (09/22/2014)

My last qualification game (of 5) I finished on 22nd September to get ridd off my provisional rank on OGS.

It was an interesting, extremly centre oriented game, where I overlet whole top side to white. The main fight took place in black’s moyo with the target to destroy there white completly, and same to kill white’s group on right side. I set on the right but same risky strategy to get the win b+58.5.

Tks to Jolly Joseki (7k) giving me the chance to play such a long correspondence game over 6 weeks.. it was very teachable for me.

With move 106 on G1 white managed a big thread with the attempt to connect its centre group. I accepted this attack by purpose, same allowing the invasion with white’s connection stone on N14 (move 84). White’s attempt to invade 2nd time with hane J8 after move 176 (H9) failed by misreading liberties (I know this very well in my own games, can happen).

09/21/2014: 1st regular ranked live game (San-RenSei/Cosmic Style) on OGS

Yesterday I played my first “regular”, ranked game on OGS after I have fixed my rank with 11k… what else: I played with a SanRenSei opening. (Rec.: Tks to bad guy Rikhon (9k/OGS) pushing me into it (whom I played later on 09/27/2014) as I had no real intention to play on Sunday evening as I play minimum 45 minutes games (+ 5×20 sec. bioyomoi)).

Tks to Dostoevskiy (9k/OGS) for giving me this opportunity. It was a very tough fight with a KO in centre, and a successfully living group by white inside black’s moyo. Therefor I had a very low expectation to win this game (result: b+15.5).

At move 198 the potentials for white were still 0.5 points winning the game. The endgame (yose) made 15 points black came back into the winning zone.

At all it was a uniquly game situation for me I experienced first time that way (after playing more than 300 SRS games).

08/13/2014: Game with large-scale framework strategy (Tygem)

This is a game being hosted on Youtube channel “LittleLamb Go“, a webcast (audio comments) on the Asian GO Server TYGEM.

The game is a demonstration of using a large-scale framework strategy (with San-RenSei opening (4 Star points) by black on right/bottom side).

In the game, both players have made several mistakes…

(P.S.: Tks to Françisa (8K/OGS) for the video link.)

Wrong Strategy against San-RenSei (two games as example)…

Does it make sense for an opponent to follow the strategy against a San-Ren-Sei player like this ?

1.) Surround the San-Ren-Sei player and his big moyo completly taking 2-3 corners
2.) after 1. completed then attacking from inside the big moyo

Here two games as example I played on Wbaduk with SRS fuseki against two equal opponents (18k) last days which show this situation. – In both games one as black and one as white the opponent died completly inside the big moyo.

(A) White attacks with move 114 on K6 inside black’s big moyo


…and so it ended deadly for White: b+61.5 points.

(B) Black attacks with move 117 on P15 inside white’s big moyo


…and so it ends deadly for Black: w+90.5 points.

Conclusion: Never attack inside a big moyo of SRS (which is secured as territory already) !

07/20/2014: game with Cosmic style (San-RenSei variation) between 5k (w) and 6k (b) on KGS

Today Sefo (9k / OGS) played as black on KGS (there as 6k) a game against 5k (white)… a wonderful example of a San-RenSei variation – as modern version (you might call it better “cosmic style“) with uniquly 6-4 opening. – Well done !

06/28/2014: Cosmic Style game with 9P (w) vs. 9P (Tygem)

Tks to GoPrince (5D/OGS) for sharing the “Cosmic Style” game… we just know that it was a 9PD game and probably being played on Tygem in June 2014.

players: fangchun (9P, white) – tenzaru2 (9P, black)
date: 28th June 2014

07/20/2014: correspondence game 12k (b) vs. 2D (w) with SanRenSei fuseki (OGS)

Tks to Marnoris (10k / OGS) for sharing… another game with SRS style. We can see black (12k) fails very early with move 15. He doesn’t end up the joseki sequence and tenuki in kakari in the lower left corner.

Black already resigned in this correspondence game (Fischer: Clock started with 1 week and incremented by 1 day per move up to a maximum of 1 week / Komi: 0.5) at white’s move 115.

07/17/2014: game with 2 x Three-Star-point opening by w + b (Wbaduk)

Another game on Wbaduk, both white (me) and black opened each with SanRenSei (2 x three-Star-point) … it looked strange how black defended its complete bottom side…. then started with an invasion to think, that hereby white’s big centre moyo can be damaged to take the won.


By purpose I didnt invade into black’ s territory as I wanted proof its possible to defend and winning the game. The top right corner stolen by black ws compensated by whitte to delete black’s bottom right corner. – And its invasion was cut on M12-N13 so black was isolated and fightes in white’s territory for surviving.

Instead the result says different: white won with 2.5 points (komi : 6.5)
