Life In 19x19

It seems moves 52 (tenuki) and 53 (punishment) turned the game in black's favor. Then it became a lesson in how to win a won game.

A few statistical notes from GoGoD.

The opening up to Black 7 is fairly rare but goes back to 2010. Its last outing was in December when Joanne Missingham as Black beat O Meien in the PCK (Zhugang) Cup.

GoGoD has 7 games, and so far it's mainly been a Chinese affair. Not a single Hanguk Giwon player appears. Yi Se-tol may therefore have been trying to surprise Gu Li, and also avoid any opening preparation.

White 8 (kosumitsuke) was tried once before, by Kimu Sujun in Japan in 2011. Otherwise White has favoured making a Chinese shimari here.

Gu's White 10 was new. Shida Tatsuya had tried Q10 (right side hoshi) against Kimu Sujun.

I know I'm probably spitting in the wind, but could we be good fellows and try to avoid "jubango". It's no shorter than ten-game match (actually two Japanese syllables longer) and conveys far less information.

What is a Chinese shimari? Does that mean C11? Sorry for my ignorance.

Thank you for posting the game record !

I don't understand black 207...I would try to save the K2 group (with G1?). I must be overlooking something.

Great start to the jubango!

It's already safe, or rather if white captures it with h1 he can't answer black g1 to the left so loses the corner which is bigger. Also those moves black played instead were sente, and then he came back to g1 to save his lower side stones in sente and eliminate the opportunity of a trade.

Yes, very interesting shape there: the n6 hane outside seemed a rather painful compromise versus the natural l6 as l8 got isolated (cut elephant jump broken shape), but Lee did it to avoid giving white sentes around k8 which would fix up the h10 thinness and thus expose the f9 thinnness (according to Myungwan Kim's commentary). But as soon as white tenukied the sharp k6 made those cutting exchanges not look so good anymore (they weakened p4). I wonder what would have happened if white continued locally, say l5 or k6. Is white really so upset if black plays something like e11 to connect on dame with weak kosumi shape?

It's silly to call this ten game match a jubango. That is a Japanese word and neither of the players is Japanese! They are certainly not playing a Japanese 10 game match

Maybe not, but show me where either China or Korea has a strong history of playing many 10-game matches! Clearly they have stolen this idea from Japan, so why not keep the historic term.

In China, 10 games match was played quite often long before 10 games match during 1930-1950 in japan.

what do the sponsors call it? The video link from BadukTV: 古力李世石十番棋巅峰决战 2014年1月26日

as far as I know, 十番棋, is pronounced "jūbango" (in Japanese): from http://senseis.xmp.net/?Jubango

so far, I don't see anything wrong with calling it a Jubango.

10 game match was popular in Japan way before 1930, sorry.

The characters are a little bit different, but yes this is basically jubango in japanese.

That is correct. In that case we also shouldn't call the name of the game "Go", but rather "Baduk" or "Weiqi". And certainly we shouldn't use the terms "shimari", "kosumitsuke" etc. (and a "Chinese shimari" is certainly a contradiction in itself).
