Го Сейгену 100!

Го Сэйген признаётся многими как величайший игрок в Го всех времён и народов. 12 июня он отметил свой столетний юбилей!

В своей книге ‘A Way of Play for the 21st Century’  мастер пишет:

"Я продолжаю изучать Го каждый день, ставя камни на доску. Вы можете подумать, что изучение Го не так уж важно для меня с тех пор как я ушёл из спорта так много лет назад. Но люди, которые играют в Го, понимают, что эта игра - внутренний друг и постоянная форма искусства. Так что я буду и дальше играть и изучать Го. Возможно, как и вы"

Многие игроки, в том числе и профессионалы, по сей день внимательно изучают партии Го Сейгена. 

По словам Youngil An 8P, Го Сейген создал новую парадигму игры и поднял понимание Го игроками на новый уровень. По ссылке можно прочитать комментарии Youngil An на памятную игру между Го Сейгеном и Китани Минору, его лучшим другом, состоявшуюся в 1940-м году. 

"Несмотря на то, что игра состоялась 75 лет назад, их стиль до сих пор ощущется как современный. Они сделали множество ходов, о которых обычные игроки никогда бы не подумали", пишет Youngil An.

This match was called the Kamakura Jubango, because it started at a temple in Kamakura, in Japan. When this game was played, Kitani was 31 years old and Go was 26. Before this game, Go was already leading the match 4-1. Kitani only won the third game, and if he lost again he'd have to take a small handicap from Go in the next game. That sort of thing is very embarrassing for a top pro, and the stakes were perceived to be higher than in the current Jubango between Lee Sedol 9p and Gu Li 9p. When I was an insei, around the age of 13~15, I liked Go Seigen's games the most. His moves were very special and his play from that time still felt very modern, even in the 1990s. Go's style was very different to that of other top players from that time. Other top players like Kitani Minoru 9p, Fujisawa Hosai 9p and Takagawa Kaku 9p played solid, but slow moves. However, Go Seigen's style of play was speedy and flexible. He was highly skilled in fighting ko, and he usually earned some points in every ko fight, which is very impressive. I replayed most of his official games at least three times, and I always felt that I learned something new from every single game. In the era when Go played, most games didn't have komi, so his play was always quite aggressive and speedy when he played White. I think the lack of komi for White probably pushed Go to develop his style further towards flexible and rapid openings. When Go Seigen became a pro, he played a game against Kitani. Go played Black and there was no komi. In this game, Go played his first move at tengen, and then mirrored Kitani's play until move 64 - when he thought there was a better move. Go took a clear lead in that game, but he made some mistakes in the endgame and lost the game by 3 points. At the time, Kitani was stronger than Go, so Go tried to make the game simpler. Perhaps he was also wondering how White could win a game of mirror Go without komi. In 2003, there was a poll amongst Korean pros, about who they thought the greatest player in the history of Go was. Lee Changho 9p took second place in the poll, and Go Seigen was voted the greatest player ever. Even though most of the pros who were polled had never played against him, they still regarded him as the greatest Go player, because they'd replayed his games. Let's have a look at the game. Go Seigen plays Black.]RE[B+Resign] ;B[pd] ;W[qp] ;B[dd]LB[dd:3][pd:1][qp:2]C[This two star formation was very rarely played at the time.] ;W[cp]LB[cp:4]C[On the other hand, this 'facing komoku' formation, with two 3-4 points, was already very common.] ;B[ep] ;W[eq] (;B[dp]LB[dp:7][ep:5][eq:6]C[This move is still common today.] ;W[dq] ;B[co]LB[co:9][bp:D][fp:B][cq:C][dq:8][fq:A]C[There are many other options for White here. For example, A to D are all possible.] ;W[bo]LB[bo:10]C[This double hane is an old fashioned joseki. It's very rarely seen these days. ] (;B[cn]LB[bn:C][cn:11][bp:A][cq:B]C[This extension was also quite unusual. Playing A to C is more common.] ;W[bq] ;B[fp] ;W[bn] ;B[op]LB[cl:B][cm:A][bn:14][fp:13][op:15][bq:12]C[Playing tenuki and moving to the bottom right is Go's style. It's very uncommon though in this sort of situation. Locally, A is the vital point for Black's shape (hane at the head of two stones), so Black would normally defend his shape with A or B now. However, Go played Black 15 instead because he placed a strong emphasis on rapid development in the opening.] ;W[cm] ;B[qq]LB[cm:16][en:A][op:15][qq:17]C[When you tenuki, like Black did with 15, it's important to follow through and tenuki again, at 17 for example. If Black had played at 15, and then gone back to respond to White 16 locally (at A for example) he'd only be taking a loss and his play would be inconsistent. In other words, if Black's not prepared to ignore White 16, then he should simply defend on the left side in the first place, instead of playing at Black 15. This is a very important concept in Go, and it's also related to the idea of fighting spirit.] (;W[gq]LB[cm:16][gq:18][qq:17]C[Jumping at 18 was big, because it reduced Black's potential at the bottom.] ;B[cg]LB[cg:19]C[Go wanted to reduce White's potential on the left side with this move. It can be hard to understand, but Go's way of thinking is that the exchanges in the lower left were forcing moves, because White's position was very low. Since he thought that, he treated his stones in the lower left lightly and developed his positions elsewhere.] (;W[ic]LB[ic:20][jc:A]TR[dd][cg]C[This splitting play is similar to A, but White was more concerned with the top left corner at the time.] ;B[pp] ;W[qo] (;B[rq] (;W[lp]LB[qo:22][lp:24][pp:21][rq:23][pr:A]TR[cn][co][dp][ep][fp]C[White's two stones in the lower right became less valuable, because Black chose Black 23 instead of A. So Kitani played at the bottom, and began trying to swallow Black's marked stones on a large scale.] ;B[ql] (;W[gp]LB[ql:25][gp:26]C[This was Kitani's solid style of play, but it's a bit slow. If you count the stones in the bottom left corner, White has four more stones, so Go doesn't care anymore if White captures all his stones there.] ;B[mc] ;W[fc] (;B[fd]LB[fc:28][kc:A][mc:27][fd:29]C[Go wanted to secure the corner territory efficiently with this attachment. If Black 27 was at A instead, Black wouldn't attach like this, because it makes White stronger, and he'd prefer to attack later. However, because Black 27 is further away and is more solid, Black's happy to take territory while also making White's stones at the top over-concentrated.] (;W[eb]LB[eb:30]C[White 30 was a nice response, which allowed White to go further into the corner.] ;B[ec] ;W[fb] (;B[cc]LB[fb:32][cc:33][ec:31][cg:A]C[This was the right move in relation to Black's stone at A.] (;W[di]LB[qd:A][ci:C][di:34][cm:B]C[Playing at A first is also conceivable.

Black doesn't atari at B, because he's potentially aiming to cut at C instead. When you don't know which move you'll prefer later, the best policy is usually to keep your options open for as long as possible.] (;W[dk] (;B[ej] ;W[cl] ;B[hd]LB[hd:53][ej:51][dk:50][cl:52]C[This atari wasn't just sente. It was a ladder breaker.] ;W[gc] ;B[fm] (;W[gm]LB[gc:54][bk:A][fm:55][gm:56]C[This hane was unavoidable, because of Black's potential move at A.] ;B[gn] ;W[go] ;B[hn] ;W[fq]LB[gn:57][hn:59][fo:A][go:58][fq:60]C[This move was necessary to prevent Black's atari at A.] (;B[ci] ;W[bk] ;B[gl]LB[ci:61][bk:62][gl:63]C[Cutting at 61 and playing atari with 63 was a good idea. The result up to here was playable for both, but since there's no komi, Black's still in the lead.] ;W[bi] ;B[ch] ;W[he] ;B[gf] ;W[ie]LB[he:66][ie:68][gf:67][ch:65][bi:64]C[This is Kitani's solid style of play again. He doesn't rush.] (;B[hm]LB[nd:A][ne:B][hm:69]C[This move was necessary, otherwise White would be able to play at A or B as a ladder breaker.] (;W[io]LB[io:70]C[This move feels a bit too slow, but it was typical of Kitani's idiosyncratic style of play. If you pause here to look at how solid White's lower left corner is, you'll get a feeling for Kitani style. Kitani's play is as solid as a rock, and he leaves very little aji and few ko threats for his opponents. Kitani was often able to exploit this kind of power by invading very deeply and aggressively later in the game. However, I think that playing on the right side would have been better for White.] (;B[np] ;W[mp] ;B[nr]LB[io:A][mp:72][np:71][nr:73]C[Since White defended at A, Go might have wanted to play at the bottom.

I felt that he was very confident about his moves in this game.

If White plays A next, Black will atari at B. Go won this game, and the overall score for the match became 5-1 in Go's favor. This meant that the handicap was changed. After this game, Kitani played two games as Black for every game he played as White (sen-ai-sen). This game showed the typical styles of both players. Go's moves were speedy and lively, and Kitani's were rather solid and firm. Go maintained his lead (no komi) from the beginning of the game through to the middle game. However his attack in the top right corner (starting with C) gave White a chance to complicate the game again. Nevertheless, White D was questionable, and E was the losing move, and Go quickly wrapped up the game afterwards. This is quite an old game. It was played almost 75 years ago, so you might feel that it's somewhat different to modern games. However, you can still see Go Seigen's brilliance in this game (F-H for example). I replayed this game when I was a young boy, and I thought that it was a kind of one sided winning game for Go at the time. However, when I reviewed this game closely again, I felt that it represented both players' unique styles well. I also felt Kitani's patient style of play and the power of his slow, but very solid moves more lucidly. It seems that this game was more complicated than I realized when I was young. I hope you'll enjoy reviewing this game, and will feel the greatness of Go Seigen on his 100th birthday. His style of play in the opening still feels quite modern in my opinion. If you have any questions or opinions, please feel free to leave a comment. In Korea, we call Go Seigen the living Kiseung (Go Saint). Happy 100th birthday Master!
