Hi everybody!
Today, a match of third round of 44th Osho's challenger qualification.
A match between Habu Yoshiharu Meijin and Murayama Satoshi 7th Dan.
Sente is Habu Meijin, but we will analyze from Gote, Murayama 7th Dan's view.
Lets analyze from Gote's view.
Here, both advance Fu of Hisha's head, probably it will be a Yokofudori.
It is a match of November 11th, 1994.
It is Yokofudori.
Here, the most common is to play 33Kaku and fight like this,
but in this match he played 88KakuNari and exchanged Kaku.
For DoGin, he played 76Hisha, bringing the match to a double Yokofudori.
This variant make the match very aggressive.
How will it become?
Advance Gin, and confront Hisha.
At this moment, if he swing here, there is the 15Kaku applying an Ote Hisha.
With this Gote would already lose.
So, he offered the exchange.
DoHisha, DoFu.
Dropped 46Kaku threatening the Kyosha.
Here, he could play 55Kaku threatening both Kyosha.
But there is the 28Fu.
In the sequence he could take the Keima making a Tokin,
this would be too strong, so he has to take it, but it would be followed by 25Hisha.
threatening Kaku and Gin, so, even if takes Kyosha, he would lose his Gin.
So, 55Kaku wouldn't have good result.
So, for 46Kaku, he played 82Kaku.
Then, DoKakuNari.
Followed by 55Kaku. Now, he is threatening Gin,
so, in the last sequence, he would be able to take the Gin.
In this match he played 85Hisha, first.
Here he threatened Kaku and Keima, and was answered with 86Hisha.
If he takes Kaku, Gin is undefended, and to make a Ryu would be very good.
Takes.
He made the Gin to advance and dropped 28Fu after that.
I doubt which position is better, but he considered this case was better.
So he played like this.
So, takes Gin.
Takes Keima.
Flees Gin, followed by Tesuji, 38Fu.
He wants to make more Tokin.
Here if he plays DoKin.
He could 26Kei.
With this...
With this, to not lose the Kin, he would have to advance, but there's the KeiNari.
When he flee Kin, the Gyoku's defense was weakened.
So, he ignored 38Fu and attacked with 81Uma.
Followed by 39.
Here he moved Tokin. To promote the Fu looks more natural,
but if he flee, like this.
At this time, this form seems to be better.
Because he can sacrifice the Tokin.
And if he takes with DoGyoku, could play 29Hisha.
And the possibility of this move with Ote is a big advantage.
If he promote the Fu, I don't know if he would flee, but in this case,
The sacrifice wouldn't have any effect.
He tried to take the advantage and played 39Tokin.
So, DoGin. Well, even with FuNari he could take with, DoGin, too.
But, like this, he limited the possibilities.
DoKin.
So, he played 55Kaku.
Then, he try to decide with 72Gin.
Well, for Gote it would be good to be able to flee to this side.
For 72Gin, he plays 37KakuNari.
Then, Gyoku flee.
And make Ote with Keima.
Maybe, the sequence 85Hisha with 86Hisha, was played to make this Ote possible.
Then, flee.
59Uma.
76Gyoku.
75Gin.
Then, DoGin.
DoFu.
Then, 66Gyoku.
In this 66Gyoku, if I'm not wrong, nowadays the 85Gyoku seems to be considered better.
But as this match was played on 1994, at these days...
We can say that the theory used now was based on this match results.
Nowadays, if I'm not wrong, with 85Gyoku they consider that Sente has the advantage.
But even though, this sequence is very hard.
In this match...
Was DoFu, followed by 66Gyoku.
Here, he played 62Kin, followed by 63GinNarazu.
Then, 86Hisha.
Defend in the middle of path with 76Fu. This part is very hard.
Well, here he could take Uma, but this would delay the attack.
Then, he plays DoHisha, to try to decide it.
65Gyoku, followed by 64Fu.
55Gyoku, advance Fu.
DoGinNarazu, then, takes Kin.
Then, plays 71Hisha.
Here he defended with 61Gin, but how would it be if he had fled like this?
If he goes up like this...
There is the 45Kei.
And how would be the match in this situation?
Well, with this 71Hisha,
When he make Ote with Gin, and he goes up it's possible to take 73Kin with the Hisha.
Would it be it?
So, with 45Kei, Sente seems to be in advantage.
Then, he defended with 61Gin.
He followed dropping 53Gin.
Draw Uma back, followed by 46Kei.
This part, Sente seems to be better, but I'm not sure.
Then, he plays 65Kin. Interesting. This Kin is a move of Attack and Defense.
If plays DoGin, he can take this Gin.
And this side become much more sake. Interesting.
For 65Kin, he moves to the side, followed by 53Kin.
Then, DoGinNarazu, so, jumps Keima.
Followed by 35Gyoku. Looks dangerous to flee to this side.
Then, 34Fu.
Then, plays DoKei. If it was DoGyoku, could drop 25Gin.
Is that so? Let's see...
If it was 25Gin, Gyoku goes back.
With this, I doubt if he is caught... Ah there is...
Could play like this.
There is some other way to play?
Well, if he play like this...
Goes up, and takes Gin, how would it be?
With this, this side can drop Fu, followed by 24Gin.
And even if he play 63Kei, could play DoUma, DoUma, and finish dropping Fu and Gin.
So, the sequence with 53Uma, it is Gote's victory.
So, with Uma...
Followed by 34Fu and DoKei.
Drop 26Gin, must to play 24Gyoku, 15Gin.
35Gyoku, 26Uma, 46Gyoku.
Then, retreat 76Ryu.
In this position, he abandoned, giving up the victory to Murayama 7º Dan.
In this position, looks like, he could defend with 56Kei.
For 56Kei, could he take it?
Is there some better move? Ah, there us this option. That's true...
Like this, 55Kin, DoGyoku, 65Ryu, 46Gyoku, 35Ryu, and it is over.
So, for this Ote with 76Ryu, if drop something at 76, could take it.
Ah, sorry, can't drop 54Kei. Even with 66Kei, would it be 55Kin?
If he play 66Kei, how would he answer?
Well, he would win, taking this piece?
Is that so?
As it opens up this escape route, it is a bit fearsome, but he could win taking it.
Take, is it right?
Is there any better move?
I believe he wins taking here.
Well, if covers with Kin, he could simply take and play 55Kin to finish.
Well, even with 56Kin... In this case...
Well, could take it, too.
Well, looks like, instead of finish it directly, he would win with this side safe.
Well, this variant seems to give the victory for Gote, too.
Then, he abandoned after see the 76Ryu.
Well, maybe he didn't defend because he considered that he already lost.
This match was pretty aggressive. I believe they studied a lot for this match.
And this match influenced a lot to define the Joseki.
Making this match very important.
Thank you very much.
