hey folks were back Chris Garlock with
Michael Redmond our latest AlphaGo
against the world we are rapidly closing
in on the halfway mark we of course are
gonna be doing all 60 of these amazing
games and Michael I believe we have a
new player today is that right yes
today's player is Mi Yuting he's a nine
dan and he's about 20 years old at the
time of this game and he was a nine dan
I think was promoted in 2013
mm-hmm when he won the MLily cup so
he became a world champion in 2013
basically so in China they promote you
to nine dan for that -mm-hmm he was how
old when he became a world champion like?-
that
would be three years before this so
17 -so young -yeah they're young and he's
famous for a complicated version of the

今日の相手は新しいね？
今日の選手は羋 昱廷九段です
当時二十歳

九段になった。
ー何歳で世界チャンピオンに？ー
これの3年前なので
17歳か-若いね-そう、そして彼は

Japanese: 
複雑な変化を打ち出したことで有名です
私の定石解説動画ではあえて解説しなかった変化です
ー今日はその変化が出るのか？ー
今回はナダレ定石です
羋 昱廷は黒です
AlphaGoの好きな布石を逆に使った
通常alphagoは右上に星を打っていたので、
上下逆ですが
同じことです
AlphaGoのケイマシマリは意外
こう打つと思った

English: 
three three the direct 3-3 joseki so
he he sort of invented the most
complicated variation of it which is the
one that I did not do a video about -and
we're not going to see that today are we?-
no, but he's gonna play the avalanche joseki
of course everybody's playing
avalanche it's why not -so Mi Yuting has the
black stones you can see he's playing
the opening that Alphago likes -yes- it's
sort of inverted from usually alphago
starts with the star point in the upper
right corner right so it's it's it's
backwards like the upper half of the
board and the lower half are backwards but
that's okay and AlphaGo
plays a knight's shimari, that's sort of
interesting because I thought AlphaGo was
gonna play it this way so

English: 
it's it's different and okay black if
you have a computer program maybe it's
gonna tell you to jump in here or black
could play something like this this is a
common move that human players play also but
Mi Yuting tried the shoulder hit
and I think already he has the idea that
he's going to try to force the
Nadare because I'm actually going back
a long ways for alphago if we go back to
the game AlphaGo played against Fan Hui
the european go champion hmm
there was a variation of the avalanche
joseki in which some people including
myself thought that maybe alphago have
trouble with these complicated josekis
look like alphago might have made a
mistake but that was for alphago that
was even before the Lee Sedol version
so it's a long time in the past of
alphago's development but maybe

Japanese: 
コンピュータプログラムを使っていればここで黒の三々入りと出るだろう
あるいはこのように打っても普通
羋 昱廷はカタツキを打った
彼の考えは
ナダレ定石に導こうとしている
だいぶん前の話ですが、AlphaGoはFan Huiと対戦しました
欧州囲碁チャンピオンです
その一局で
ナダレ定石の変化があって
alphagoは複雑な定石を苦手としているという印象があった
それはalphagoが李セドルと戦う前のバージョンだから
alphagoとすれば大昔の話だが

Japanese: 
羋 昱廷はAlphaGoの理解を試す考えがあったのではないか
ナダレ定石
実際ニューラルネットワークシステムを使用するAIは
部分的な結果に関しては曖昧
結果を示さない
全局的な判断で評価値を出すから
部分的な戦いはどうだったのか
理解するのが比較的難しい
コンピュータが間違っている意味ではない
-ブラックボックスのようだ-さて、
白は三々に飛び込んだ
この碁は珍しく

English: 
Mi Yuting had the idea that he could test
test alphago's understanding of the
avalanche joseki because we already had
the idea at that time that maybe
alphago maybe computer programs in
general using this neural network system
were having trouble focusing on local
variations and it's actually true to a
certain extent we do have trouble
getting local answers out of the
computers because they always deal in
full board positions they always give
the score according to the full board
position sometimes it's pretty hard to
get the message as to what was good or
bad about a local fight, doesn't mean
that the computers don't understand it
means it's hard to decipher basically
- a bit of a black box - yeah
white jumps into the 3-3 point so
actually in this whole series this is
going to be a very unusual game firstly

Japanese: 
alphagoは序盤早々から地を取る
黒も大ゲイマで三々入りを誘導した
そして黒、つまり人間が、
評価値が高い
高いといってもほぼ互角という意味ですが
黒ツギ、白ハイ、黒ハネ
これはは当時の流行。
今は黒ハイが主流かな
白2線オサエを打たせない意味です
このようになって
白は隅に一手かけるだろう

English: 
because alphago is going for territory
here also very early in the game and
also and black is sort of inviting that
with this move the large knight's move here
and also there's the fact that the black
player the human player is going to have
fairly good winning percentage, in that  I mean about even, it doesn't get so
good for the human but it's gonna be
about even for a long time into the game
a relatively long time so Black
connected here white crawled and black
played the hane this is a variation of the
joseki that was played a lot at the time
in modern games you often see black crawl
instead of connecting and that's to stop
white from at some point playing 
covering on the second line so if black
crawls then something like this could
happen and then white would probably go
back to the corner anyway because
covering at this point would be a very

Japanese: 
黒からオサエが大きいから
古い定石はこれだが
白は2線にオサエて問題です
だから黒ハネ、白ブツカリとなって
人間の間で流行っていた手順です
黒の厚みが右辺に向かっている
白はキカシを打ってから
昔からあった大ゲイマシマリ対策です
囲碁AIはこのツケをよく打つ
AlphaGoも後で打つようになる
このマスターというバージョンは
呉清源が使った打ち方です

English: 
big move for black to play next in the
game he just connected white crawled and so
if black does continue with the old
joseki which is this one and white would
be able to to cover here and maybe make
some trouble with this kind of fighting
in into the side so he plays this hane
white bumps against black and here this
is exactly the same as the humans were
playing it at the time and black has
this nice influence pointing towards
the right side of the bord or towards
upper side depending on how you view it
white plays these forcing moves and
we're gonna see an old-fashioned way to
deal with the large Knights corner
enclosure because we have been seen a
lot of computer programs play this right
and we've been seeing in the later
versions of alphago we saw AlphaGo
playing this move too but in this master
version AlphaGo was actually going to
play the move that was this is a move
that Go Seigen liked to play so it's

Japanese: 
何十年にもわたって
使われてきた白の打ち方です
形を決めて辺のヒラキを打つ
一応機能している
32手目ですが黒の評価値は48.5％
KataGoによるとその数値になった
半目か、1目半の差です
細かい
他の碁と比べて32手まで細かい
善戦している
ー私がAIと打つときの目標は
少しでも細かい碁にしようと、

English: 
been around for decades it's an
old-fashioned variation where white
place these forcing moves and then can
extend on the side and you can see it is
functioning fairly well for white towards
the right side at this point we are 32
moves into the game and blacks winning
percentage is 48.5%
according to KataGo at least the time I
did it and that's like maybe he's going
to win by half a point or one and a half
points I mean maybe he's gonna lose by a
point or one and a half once it's that
close
it's very close this is the closest that
any of the games of been at 32
moves into the game so this is pretty
impressive I think -yeah yeah I mean when
when I when I play the AI my goal is
just to keep it close as long as

Japanese: 
最後は負けてしまうがー
ここで羋 昱廷はナダレ定石を意識しているようだ
alphagoがナダレ定石に対応できるか試そうとしている
カカリから黒オサエなら普通だった
つまり全体を見ると
右上の黒は固い構えで
白は右辺を荒らして
碁盤の右側は
大場を打ち終わって価値が低い
急な攻めもないし非
だから左辺が焦点です
右上の黒が固いから

English: 
possible I know I'm gonna lose but keep
it close-  so now he pushes and this is
where Mi Yuting is seems to be trying to
set up the avalanche I think he's trying to
test alphago and see if it can deal with
the avalanche because otherwise but he could
have just played an approach move here
and covered this would be the more
normal way of playing since in this game
the reason I say this is normal is
because black has this very solid
position in the upper right corner and a
strong position here too while white has
split the right side if we look at the
right half of the board in general the
value of this whole area of this whole
area here it has been reduced by the
fact that it's pretty much filled with
stones and none of them are really that
much in danger and so it would be very
normal for black to be focusing on the
left side of the board just the fact
that these stones pointing out here are
so solid the upper side is not as

English: 
important and so with this move in itself I
don't really like the direction of
blacks play which is heading towards the
upper side which black could have given
to white with little loss just the
fact that black is so solid here it
means that black could have allowed
white to play in that direction and if
White's moves in that direction would not
have been so effective so that's why I'm
suggesting it's more natural for black
to be playing this way on the left side
of the board not something like this
this is what I would like to play and I
think it was getting a good score with
the computer programs too but I think he
just wanted to test alphago's
understanding of the avalanche joseki
and AlphaGo could have avoided
the complicated variations by playing
for instance something like this but it
turns out AlphaGo went right into the
most complicated avalanche joseki so we
thought we're gonna see if it knows how

Japanese: 
石の方向としては
右辺に向かうのは疑問
右上の黒が固くて
白は上辺を打っても効果が少ない
上辺を白に与えても損が少ない
だからさへんを囲えば自然だと感じる
私ならこう打つ
囲碁AIの評価値もよかった
だから彼はalphagoをナダレ定石で試そうとしたのではないか
そしてAlphaGoも簡明に打つなら
こういう手もあった
しかし難解定石に突入した

Japanese: 
そしてすぐに
alphagoは定石から外れた
定石よりいい手を打った
当時は定石を知らないのかと思っていたが
実は定石を超える手だった-Wow-
白のハネは
シチョウに取らせない工夫
白ハイとなって
黒は今のところ
この石をシチョウに取る手はない
白のこの一手は簡単に取らせない意味だった
この変化は
以前あったナダレ定石の変化
100年近く前に

English: 
to deal with them and almost immediately
alphago is gonna play a move that is not
the joseki -oh yeah- and it turns out this
is probably better than the joseki-  oh no
I was thinking oh it doesn't know that
joseki after all and I think he had made
a mistake but no this looks like it's
better than the joseki -Wow-
so white plays here this is to stop
Black from capturing this stone in a
ladder so White's gonna play this one
forcing move here -mmm- and black jumps out
white plays the forcing move here
and went white crawls you can see for
the time being black has no way to
capture this stone in a ladder so that's
that's what that white stone here is
doing is it's making it a bit more
difficult for black to capture that
stone and this is actually a variation
it's very similar to a variation of the
Avalanche joseki that came out at the
beginning like almost a hundred years
ago it was a bit less than a hundred

Japanese: 
呉清源がナダレの新変化を打っていた
まだ定石がなかった
呉清源の新手に対していくつかの変化が生まれた
そしてそのうち今の定石になった
これは消えた変化の一つで
私たちは白失敗だと思っていた
しかしこの局面では有効です
隅の白地が大きい
黒の中央は発展しない
白の評価値は60％
黒40％
盤面で黒2、3目勝ちか

English: 
years ago when Go Seigen started playing
these variations and no one knew how to
play it and they were inventing all
these new josekis to deal with this
innovation that Go Seigen had done and
so there were a number of variations of
the avalanche joseki that finally settled
 down into a set joseki
that we everyone plays now and so this
is very similar to one of those but we
didn't think it was so good with white
crawling so much on the second line it
turns out in this board position at
least it's pretty good for white the
corner territory here is pretty
important and blacks not gonna get
enough out of the center so yeah that
was a big surprise at this point of the
game white is more like is pretty close
to sixty percent actually so it is
getting good for white so black is
somewhere around forty percent only
winning by two or three points
on the board and in his next move he's

English: 
gonna make what I'm gonna call the
losing mistake actually this game I
think it went to a half point so this
was a half point game in which alphago
was way ahead but it gave away most of
its lead in the end game and so that was
I was very annoyed about that at the
time I think this might have been one of
the games that I did a commentary for
you -hmm
and on the aga website I mean the
YouTube site but this was a point where
when black extended and white got to
extend here putting pressure on these
black stones here this was a point where
White's lead is expanding its it's very
close on the board Black has 37% when you
present it's according to Katago
so what black should have done is black
should have played this and this is
something that people picked on picked
up immediately like this was obvious to
people watching the game and in the after
game analysis we didn't need a computer
program to tell us about this move
actually

Japanese: 
黒の敗着を見せよう
実は半目になったんだけど
終盤でAlphaGoが大損をするのです
当時私はイラついた記憶がある
私が解説したかと思う
AGAのYouTubeチャンネルで
黒単ノビだったので
ここのノビを打って白優勢が拡大した
盤面勝負で、黒の評価値が37％
黒はアテを打つべきだった
当時も皆気が付いていた
生で見ている人も、局後の研究でも
AIに頼るまでもなく分かっていた

Japanese: 
-mmm-hmm-この交換は黒の権利です
それだけ打ってここにノビがよかった
白はもう一回ハイを打って、
白は2線をたくさん打っている
当時は黒がいいかと思っていたが
実は少し白有利です
盤面で黒2、3目です
私は計算できなかったが
KataGoを信じます
白はノビを先手で打てたのです
変化では上に黒石が並んで
白は2線を打たされていた

English: 
-mmm-hmm- Black can play this exchange it's
gonna be forcing white has to answer and
then black can extend here so it would have been better for black to have that
exchange in White will probably crawl
once more and you can see black is
forcing white to crawl a lot on the
second line on the side so we thought
this was gonna be okay for black it
turns out the overall position is
slightly better for white and so alphago
is saying that black can only win by two
or three points on the board it's not
something that I can calculate so I'm
gonna I mean KataGo was saying that I'm
willing to believe it but I it's not
something that I would be calculating
during the game in the actual game when
white gets to extend here black had to
answer that and just at that difference
there were in the variation I was
showing you with a line of black stones
and with white being forced to play on
the second line in this case white is up

Japanese: 
外の黒の厚みが
だいぶん違います
盤面勝負だから黒は苦しい
さっき言ったように、、AlphaGoはヨセでリードの大部分を返した
難しかったのは
逆転のチャンスがあったのか？
実際はAlphaGoが終始優勢だったようです
最後に何目も損をする
ー楽しかった
よくそこまで研究した
AlphaGoの新手が出たし
素晴らしい！
皆様楽しかったか？

English: 
on the third and fourth line there's
just a significant difference there in
the strength of black's outside thickness so
the game continued like this but it was
already very difficult for Black
now it's very close on the board but as
I was saying alphago gave most of it
back in the endgame and so this is the
one one of the games were it's sort of
complicated trying to figure out whether
the human actually had a winning chance
because it did end up being a half point
but I think that alphago stayed ahead
throughout the game when they entered
the endgame it was like it was close
before komi but AlphaGo gave most of
that away -this is this is really cool I
mean to see you know I just like you
that is so you know so well know so well
researched and alphago coming up with a
you know a different move that actually
adds to that that's that's pretty cool
that's gonna excite you as a go
historian yeah excellent well folks that
