Hello, everyone.
This is the 63rd NHK cup television Go tournament.
I am the moderator, Nagashima Kozue.
This is the 16th game of the second round.
B Block.
Cho Chikun 25th Honorary Honinbo vs. Kobayashi Satoru 9 dan.
Please enjoy.
After the nigiri, 25th Honorary Honinbo Cho Chikun will go first.
Komi is 6.5. Each move will be made in less than 30 seconds.
Each player will be given 10 periods of 1 minute byo yomi.
Have a good game.
Now to introduce the players.
25th Honorary Honinbo Cho Chikun playing as Black.
59 years old. Born in South Korea.
Studied under Kitani Monoru.
Plays for the Tokyo branch of the Nihon Kiin.
He beat Tanaka Nobuyuki 2 dan in the first round.
He is now in the second round.
Kobayashi Satoru 9 san playing as White.
56 years old, born in Nagano prefecture.
Studied under Kitani Minoru.
Plays for the Tokyo branch of the Nihon Kiin.
Has played in the NHK cup for 13 straight years.
This is the 30th time.
Seeded for the first round.
He is starting from the second round.
Now to introduce the commentator.
O Meien 9 dan. Thanks for being here.
What will be the highlight of today's match?
25th Honorary Honinbo Cho Chikun has the most titles.
Yes that's right.
During the time where he had the most titles, he lost to Kobayashi Satoru 9 dan.
They played against each other in the Kisei match for three years running.
They really have a special relationship. They are both special players in their own way.
I think that feeling will show up on the board.
I think it will be a spirited game.
Now then....
He approached, he blocked... here...
4 star points.
All stars.
This opening has been popular recently.
This has become kind of my theme.
I have different thoughts on the subject.
So approaching here and here...
It's one way of playing and it's quite common.
I didn't expect Cho Chikun to play this.
Really?
Yes a bit shocking
Then the 3 star point formation and then the pincer.
If Kobayashi Satoru were playing Black then I'd understand.
Looking at the board, if you asked someone, they'd say it's Kobayashi Satoru playing Black.
I think it's interesting that Cho Chikun is playing this opening.
Let's talk about the win/loss ratio between these two players.
Cho Chikun has 31 wins to 29 losses.
This is actually their 61st game against each other.
I see.
I thought that Cho Chikun was in the lead.
I thought that was the case, but they are almost tied.
You'd think the player with the most titles would be clearly in the lead.
It's kind of unbelievable.
Well...
Back to the game. The bottom has become a running fight.
The game will progress from here.
For a while, the running fight at the bottom will be the main focus.
O - 9 dan, earlier you were saying that it's rare for Cho Chikun to play this opening.
It is rare.
Seeing him play like this...
I was thinking it might not end up so well.
Playing like this...well...this might be...how to call it? "Fresh?"
It's interesting. I'm happy.
Well, in the first round...
The order may have been different.
Cho Chikun used the 3 linked star formation. He won with it.
Playing the 3 linked star formation, like he did in this game...
with two approach moves...
the meaning of it is a bit different.
The focal point is the upper left, the approach move there.
Just looking at this...if this happens...
Black is being attacked.
This stone may be useful if a fight breaks out in this area.
It's something he can aim for.
This would be if White wanted to attack right away.
Using this stone in a fight would only happen some time in the future.
So aiming for something far in the future vs. being at a disadvantage right away.
The Cho Chikun I know, I think he thinks that playing this right away might not be good.
Whether this is useful or not remains to be seen.
Both players are thinking very carefully about whether or not the approach here is a good move.
Kobayashi 9 dan has used his thinking time.
Well, looking at this area from White's perspective.
White doesn't want to forcefully attack Black on this side.
He'll want to do something to make use of the weakness over here.
He has a bit of room here.
If he played something here White would be busy.
Well, you want to play here.
In the game he played from this side.
Blocking like this is a good move.
Against this two space jump, this shape is commonly seen.
This move does aim at Black's weakness.
We'll play from Black's perspective.
This move would be good but here...
I'd be worried about something happening. This move would be thicker.
I think either this or this.
I think Cho Chikun will play something like that.
He's used his thinking time.
They're both students of Kitani Minoru.
They've also played many games against each other.
They think each other as special opponents.
When they were studying under Kitani Minoru they lived together for awhile.
Their relationship is closer than most Go players.
Kitani Minoru is his junior (kouhai) and Cho Chikun may be a bit intimidated by him.
Shoulder hit.
The shoulder hit is a clear cut move.
I'd play it too.
In order to make the upper left work I would play so that there wouldn't be any weakness.
You want to be in a position to attack.
I actually want to play Black.
Cho Chikun won't play moves that are normally played.
It makes me really happy.
Do you think that Cho Chikun's style has changed?
For the most part...
It hasn't for some years.
He focuses on a lot of small things to win.
He prefers to play hard and win quickly.
It feels as if all of the Black stones are working together.
There are times you think your stones are doing their job, and the opposite actually happens.
You can plan how to use your stones, and then it turns out the way you want.
However it's not always straight forward. That's the way I was taught.
Whenever I play Cho Chikun, he teaches me a lesson and shows me my stones don't work the way I think they do.
He can play a full board fighting game.
He'd be happy to play that.
Hmm, the peep here. White doesn't just want to directly connect.
The moves from here on out are going to be subtle.
If he doesn't connect then Black pushes through.
He might play a one space jump to the right.
That's the kind of move...
That's the kind of move you want to play.
The move does fend off a possible attack.
If you White were to play a knight's move on the space that is one to the left of the peeping stone....
Black's position would be difficult to play.
That's the reason he peeped.
He decided quickly.
He doesn't have a lot of time. This is a short game.
He decided this was playable.
Now their groups are cut.
The fight at the bottom will get even fiercer.
This won't be a simple game.
They basically skipped right over the opening.
The fighting has begun.
Now we have the fight in the middle with the two White and two Black stones.
That is the crucial point. You can't throw those stones away.
They will be playing a lot of moves before that is resolved.
Look at White's crawl...
The next move would be for him to hane.
He played on the vital point.
He played solidly.
This fight looks to be even.
Well, about Black's move he just played, where he pulled back.
It has a bit of a heavy feel to it.
The stones are close together.
Yes, that's right.
It shouldn't be a problem if Black's stones are stronger than White's.
Now, for White...
The move you want to play is to attach here.
However, there is the hane.
Now what happens? That's the problem.
Is it bad to just block?
Here...you want to avoid playing here.
Ko isn't good. If you connect these two points are interchangeable.
But....
It's hard to make eyes.
I feel like White is under attack.
I think this would be a difficult game.
Jumping here would be normal.
After he protects how do you counter attack?
Can you fight in this area?
There isn't a move to stop Black?
Well, this is here, so it's not certain.
Well play here, and then go back.
Pushing through and cutting..
White is okay.
However this works now.
Now the cut works.
This will be captured next.
He won't peep right away.
Since the peep does work, then maybe this move isn't so good.
So this is a difficult game too.
Well, what about the diagonal move?
It's a thick move.
It might work.
Is it too slow?
It does come out solidly.
This part is difficult.
Diagonal attach.
This is a fierce move.
I didn't see this coming.
He has a plan with this move.
This move shows that he has confidence in this fight.
He's limiting Black's options.
Could he have jumped?
Black's extension is what you'd normally want to play.
How does White defend against it?
I feel it might be painful.
Oh? He's playing there. This is the vital point.
Wow.
Now we've arrived at the critical battle.
The real fight has begun.
This move is hard hitting.
So if he pushes through and cuts at the star point...
If he pushed through and cut he probably could win the capturing race somehow.
This is big.
So now cut.
White plays this, and Black tries to capture.
You can play lightly now.
White can make sabaki.
Black can atari here. If White connects then...
There's a cut here.
Now he's captured. Only two liberties.
Is this okay?
If you take then you play like this...
Here you need to have Ko threats.
There aren't any.
Like this, White managed to settle his group.
The question is if Black extends.
There might be other moves for White than descending here.
Does just connecting work?
Black adds a move here.
Attach.
Like this...
This is even.
If Black can win the race that'd be great.
If White had played here then Black would like to force with this move.
By attaching.
Then attach here.
Before playing a forcing move here...
Another fierce move.
Giving up those stones would be painful so he played this.
They're fighting head to head.
He must have read out that this works.
He might regret playing this down the line. However, it doesn't seem like he's in trouble.
Black will get cut, and now we'll see if Black has a good move.
He'll be pondering this for a bit.
If Black fills in a liberty then he should be able to win the capturing race.
I don't think White will be dissatisfied though.
I saw this variation once he played the diagonal attachment.
White sacrifices the two stones on the right.
Yes, he loses the capturing race.
He's captured.
White can fix his shape after he throws away those stones.
He decided the result wasn't bad. Very calm.
I would be really careful.
As Black? Yes.
This is what White wanted.
The right side is solid now.
Black is settled.
Now White is also....
In the middle...
White has gotten himself into the center.
White still doesn't have enough eye space.
Black can still attack.
They've quickly used their thinking periods.
White lost quite a bit of territory here.
He has forcing moves. Here and then descending, then the hane...
Then descend. This does make some eye space.
There are some moves that can do that.
Then White jumps. This White group is stronger than this Black group.
He can make up what he lost elsewhere.
When Black plays something like this...
White won't attack. White will have to make eyes.
The fight at the bottom is now how to attack this whole group.
This is a crucial battle.
They're both trying to figure this out.
So then this might get attacked soon.
There it is.
Just jumping wasn't aggressive enough.
Now he'll attack the Black group on the left.
White also gets out into the center.
White thought that this was important.
Now he's moving his group into the center.
That's the direction he's heading.
O 9 dan, you participate in a study group with Kobayashi, right?
Have you played him?
Actually in study groups we focus on going over games I've played.
We don't play.
When I have a question about the game Kobayashi Satoru is there to help me.
It happens a lot.
He does a thorough job.
What are your impressions as to Kobayashi's style?
Well let me think.
He knows a lot about Go.
But the jump he just played...
It's sort of...
I thought he would play somewhere else.
This move here?
I thought he'd play here and then this.
Then pressing down would be better.
This would be easier.
I thought he'd try this.
Well, over here, letting Black jump here, the center is scary.
White is okay over here.
I thought he'd settle his shape over here.
Like this, the next move is difficult.
He simply jumped.
I was thinking to myself to play this and then see how Black responds.
Severe move.
Severe?
Well looking at what Satoru san just played.
Now that he's played like this it means there's no need to play the sequence I showed.
They're heading towards the top anyway.
There might be a move that could disrupt his connection.
I think that nothing horrible will happen if he doesn't protect.
You mean in here?
When you have these jumps, if there are stones around...
A move like this...
Like this and this, then...
White is connected.
If you really want to cut then there is the wedge.
If he plays here then this...
Like this?
You can cut like this.
Let's say you play from this side...
This move works.
Then like this.
This move has to work or none of this works.
In any case, White has some eye space at the bottom.
He's not going to cut.
It doesn't work.
In any case, this part becomes territory.
White doesn't have much choice.
He played.
He's protecting the cut.
He's protecting against the move I showed you earlier.
Playing there prevents the cut.
Looking at Black on the right...
His territory there is big.
He has some moves he wants to play there.
White might not be able to do anything about it.
The next move...
Now what will Black do?
If he doesn't protect is he cut?
If he doesn't play, there is this wedge.
Because there is this wedge he protects here.
Black is forced.
If you play here there is still the wedge.
If you cut now...
Come out. Cut.
Black can get out.
He can jump on this side.
This move doesn't quite work. It's hard to play.
This move is also difficult because then this works.
Probably he's thinking about playing elsewhere.
He already has a lot over here. He's thinking about somewhere else.
He's still using his thinking time.
He's deep in thought about what to do.
Well earlier you said that after they cut each other that this area was the crucial point of the game.
The situation has changed.
White threw away two stones in the lower right.
He took a loss in territory.
Now Black has a large knight's move on the right.
Black then got capped on the left side.
White has lost quite a bit of territory.
He's also thinking about throwing away the group in the middle.
White would need to play another move to kill them.
If Black adds another move elsewhere...
he will be in the lead.
Playing elsewhere feels natural.
He doesn't want to be captured.
He's going to try and save those stones and make something happen.
Depending on the way the game goes, the moves on the right may factor into the fighting.
Playing elsewhere would have the opposite effect.
It's a question of whether Black can fight.
Speaking of the push and cut, from White's perspective...
He jumped.
He gets out ahead.
Black has some reinforcements at the top should this turn into a messy fight.
He shouldn't have a problem if White doesn't attack him.
His approach move at the top is acting as reinforcement.
It might turn out that way.
I think they're even.
They both have unsettled groups.
In any case, as long as they play solidly. Keep your groups stronger than your opponent's.
That will decide the game.
Where are the big points?
Somewhere in this area?
Actually I think here.
If I were playing...
I'd think this would be a good move. I'd play it.
I worry about these stones the most.
Same goes for Black.
If I'm behind, I would still play it and say I made a mistake earlier.
I'd play this no matter what.
This move is also good.
I want to play here.
So he played here and then Black jumps.
For example, keep jumping...
Play something over here.
Now we'll see if Black has the advantage if the game goes like this.
However, now that I look at it...
White's group here isn't alive.
I don't think there's anything to do about it really.
Large knight's move.
Well these stones have eye space.
Even if Black comes through here.
White might have trouble making eyes.
I didn't expect a move like this...
It feels dangerous.
The lower right doesn't look good.
I think this move is brave.
So White is saying "If you're going to attack me, do it."
He's not afraid of being attacked.
He can't make eyes though.
Let's say he plays over here.
For example, the peep here.
White connects when Black peeps.
White plays here in response.
White has no eyes.
If Black plays here then he has to make eyes here.
While he's doing that this side becomes territory.
I'd be scared.
He might play this move.
In the game he played here.
In this case play here.
This is complicated.
This is easy to understand. He's running away.
He got cut off from the center.
He's not completely alive yet.
You don't want to be cut off from the rest of the board like this.
For example how about this?
Extend.
This would be alive for the most part.
There's one eye here, and then here...
One eye yes...
This move makes eyes even if Black plays first.
Just playing moves to make eyes isn't good.
I'm not sure if it's good or not.
He played elsewhere.
Now he peeps.
White is daring him to take away his eyes.
Everyone has their own way of evaluating the situation.
It looks like White has his work cut out for him.
This makes the kosumi in the upper left really big.
If Black were to get gote...
Black has a burden to bear.
Even if he puts pressure on the White stones...
White just needs to live and then play in the upper left.
If Black gets gote and White gets to play the diagonal attachment in the upper left, then the balance of territory will shift.
That is the difficulty from Black's perspective.
If he plays here, then here...
Yes right there.
If he plays here then there is a double peep here.
Peep here too.
Then cut.
White is connected.
White can fight back.
So now, here...
He'd prefer to fight with this.
Now White comes back.
I think he's considering something like this.
Locally speaking...
He could play something here...
There are possibilities here.
Now White can come through.
This doesn't work.
So there's a problem.
They both don't have much time left.
There is still a lot of fighting to do.
This is the main conflict.
You don't want to use up all your time.
Black is thinking about how to defend against White's push.
It's a tough choice.
In any case no matter what he does it shouldn't be bad.
However, the differences are subtle.
It's difficult to decide which move to make.
White still needs two eyes though.
Who knows if he'll be able to.
Cho Chikun is out of thinking time.
Well that's both a good and bad point of Cho Chikun.
He thinks carefully during fighting.
He likes to see who will blink first, and then see who is standing when the dust settles.
He's not going to play until he is satisfied with the move he chooses.
He doesn't want to back down.
When he isn't sure what to play he won't make a decision until he's sure.
He's thinking about connecting right next to the White's peeping stone.
He's also thinking about whether White can break into the right side.
He's going through all of the moves.
Thinking about whether there are other moves.
There are many options.
He connected.
Spirited move. He is trying to resolve the fight directly.
In doing so he may take a loss.
Locally speaking this should resolve the fighting.
Black has to protect against the double peep.
So the move I showed you earlier on the board...
Where Black extends to protect the peep.
He might kosumi instead.
Like a tiger's mouth?
He's thinking about that.
They both have their pluses and minuses.
There?
From the outside?
Peeping there...
Will he extend to block?
If White connects?
This is Black forcing White.
There was a chance for White to extend.
My bad luck.
White extending to block might have been a bad move.
If he plays a tiger's mouth...
it might make his own shape weak.
I see.
This is good shape.
This effectively surrounds.
For the moment.
This might be risky.
You can't play this unless you've read it all out.
If White gets cut...
Like I showed earlier, if White is cut then he'll play a knight's move into the Black territory on the right.
Black won't cut.
White can't leave the cut there forever though.
White wants to play one more knight's move.
There it is.
This is what he was preparing to do.
This move will limit Black's options for his next move.
Now what next? Black is thinking about his next move.
He doesn't really have time.
I feel like White eating a stone wouldn't be bad.
Start with the double peep.
Peep, connect, then cut.
I really like taking stones.
I'd be happy to capture.
Taking a stone would make his stones stronger.
He'd get closer to living.
There it is.
I don't think there is anything about this that'd make White unhappy.
I'd take the stone and then I'd switch to the upper left.
The game could progress that way.
This all happens because of the peep.
White is still a long way from living though.
Do this before taking.
This is reasonable.
Make himself stronger before cutting.
There was a possibility of a wedge there.
This is going to be a long game.
If White can break into the right side...
He has a lot of different moves to do it.
There are still weak points.
Black gets sente.
Now the upper left.
This will help out the stone in the upper left.
It aims at connecting.
White has managed to survive.
There were other moves that White could have picked to survive with his weak group.
I think he's pretty tough.
Attach?
This is the shape.
Next will be the hane.
That is the shape.
The way White is playing makes me think he thinks the position is good.
So Black will hane in response to the attach?
White might double hane and then Black will have a hard time responding.
There could possibly be a ladder.
Well, we'll see if that actually happens.
It'd be strange if he doesn't hane back.
If Black just connects and doesn't do anything else.
White's hane might be a bad move.
Yes, he might descend instead.
Black might show some fighting spirit and cut though.
I think White will make good use of the cut.
The result of that would be...Ah!
Coming in from this direction?
Responding to this move is easy for White.
If he connects then Black will push through.
He'll get cut.
Yes, that's difficult to say though.
He needs time to think.
White didn't have to do anything..
There are various spots on the board White would like to play.
He wanted to save this move for later.
If Black cuts from this direction
white connects and now he can cut.
Now here and then connect. Nothing special here.
This is a forcing move.
Connect, and then here.
This splits Black.
This would be painful for Black.
Normally you think of cutting here.
Let's think about this one. Connect and push through.
Which one, this one?
There are two spots aren't there?
If you play here...
Play here and then these two stones die.
So therefore cut and then this...
Extend.
Like this?
Then something here.
The atari here is a great move.
Now White doesn't have an eye.
Also this atari is left over.
This shape is scary for White.
What about the game? One more time?
You have to read this all the way through.
Neither of them have any thinking time left.
Connect here and then over here.
What about this?
At this very moment White doesn't look good.
Therefore...
There is a possibility he won't connect at all.
So take...
So no ko, just connect.
Then something like this.
Does he play here?
Is he okay?
If he blocks then he comes out.
This would be perfect.
So what about this result?
Taking this Black stone is big. Will he play it straight away.
He connected.
We'll just have to wait and see what happens next.
How will this all end?
Kobayashi Satoru has some way of dealing with this. He has a plan.
Some good way of dealing with this.
I thought the fight was over, but now it's getting exciting again.
Of course.
Neither of them just connected.
So they cut.
Cho: No time left.
Will Black cut and try to capture?
Simple.
So simple.
He could've played the atari.
Cut and atari, and then cut again...
There was a chance for him to get out with the atari.
Yes, moving out with the stone that White had captured previously.
The game has taken another turn.
But....
The stone that White captured could run away.
This was unexpected.
Yes, the stone that he was sure was captured...
It'd be scary for it to run out.
There it is.
If this was his plan...
He should've done something else.
Maybe he should've played something different.
That's what I'm thinking about.
It seems that Black has taken some damage.
Yes, that could happen.
Black feels good.
This is an exchange of territory.
What happens if he plays the knight's move on the right side right now?
He can run away. White takes these two stones.
Well the situation is clear now.
Cho: I don't get it.
I feel like we're in another world.
Exchange of territory (Furikawari).
Whit has also come into the right side.
Well, big moves are big.
I can't really say anything about it.
Can White be cut? Yes.
I'm not sure it really works though.
Black's position on the right side isn't settled yet.
White can play the knight's move and get in with one move.
White can capture at the top.
It's a move you want to play.
If Black plays there...
Yes, White gets captured.
I like taking stones.
When I take them I look happy.
White just directly connected.
So Black should do something at the top.
If Black runs away at the top, who will be ahead in territory?
The upper right...
it's now Black territory.
Well, he did capture but...
The corner isn't settled yet.
The lower right can be reduced.
White has the lower left.
On the right side, White has a way of coming in. It would be a very good move.
Another unexpected move.
I thought he'd cut.
I thought he'd play elsewhere and focus on the corner.
That would be normal.
Playing elsewhere is not that fantastic.
I thought he'd attach to protect the corner.
That would be normal.
The lower left Black group is not settled yet.
It's not that weak.
It's won't be an important area for a bit.
Cho wants to go afer the White stones in the middle a bit more.
Right in the middle.
He might have been able to go in deeper.
He wants to reduce in sente.
White can hane and capture.
He wanted to keep pushing in.
There it is.
That is the vital point for the shape.
Now what will he play?
One space jump.
He's lightly jumping in.
Black will block.
White will jump into the 3,3 point.
Now he'll live on the inside.
It's possible for him to cut off the Black group at the bottom later.
Black has captured two stones but he's doesn't have two eyes.
Depending on the situation.
It could be very effective.
Neither of them have much time.
They're playing and really pressed for time to think in such a complicated situation.
White must play in the corner.
White wants to live in sente.
Black can push at the spot just above the 3,3 point.
Push and cut?
I don't think Cho expected White to just push through.
By playing there, White is also cut.
He didn't think it'd be played.
The eye space isn't clear?
Things have gotten interesting.
Exciting.
He must cut.
He blocked in an unexpected way.
If White connects, then Black will push through?
Right, White connects, Black cuts.
If he connects at the point where Black is peeping..
Then he'll cut. Then it's a forcing move.
Awesome move.
The timing for the diagonal attachment is just right?
Black must capture the two stones.
He'll connect at the peep.
I'm not sure what will happen next.
Now that Black is cut on the right...
If he plays, he can definitely make two eyes.
But the move he just played, if he does that...
He went right in.
Does White have two eyes?
Black made a mistake.
The move he played was a mistake.
Black doesn't have a move in the corner.
Both of Black's groups are not alive.
The bottom will live.
It's cut though.
Right there. Black is cut there.
White must answer.
Black will live on the bottom.
It doesn't look like White can win a capturing race if Black cuts.
White will need to add a move and then Black can live on the right side.
Doesn't White get sente?
Sente is big...
After Black lives...
Cho: Terrible.
I'm not sure if White is alive yet.
It doesn't seem like it.
White can play something in the lower right corner. This would be very big.
I think it'd be helpful.
I think on the whole White was successful.
All of a sudden...
White's group in the lower right...for the most part...
It seems alive.
Yes, it does.
White needs to connect the top part of his group with the center part.
Black will then live on the right side.
Does White have something in the upper right?
Block.
Black can find a move to live on the right side.
There is a wedge there.
Capturing those two stones with one move would be thick.
Cho: Horrible.
Cho chikun is mumbling again.
He thought he had a move in the lower right and then it didn't work.
He lost some territory.
Locally this is a failure for Black.
Now what will White do?
What will White do? Oh? Go for those two stones.
That move means he has a lot of confidence.
White no longer has any stones in danger.
White is doing better and better on territory.
If he keeps it up and wins...
Should be simple.
Who is leading?
White took those two stones and now everything is alive.
All of White's stones are connected.
They're connected in the center.
If Black were ahead it'd only be by a little bit.
Now that I think about it, Black is in a bit of trouble.
Black has big territory in the upper right.
If White gets a move there...
It might all go away.
How would White come in?
Maybe he can't at all. I may have went too far there.
He can reduce with a knight's move.
White was aiming for this move.
Now that White is thick, he should have some good ideas.
Black has to defend.
If this attach works, White will be in the lead.
This was a forcing move.
Normally you play on the 5,2 point...
Gives you some breathing room.
If you descend your opponent will attach...
Pull back.
So now does Black want to go into the 3,3 point in the lower left?
The 3,3 point becomes possible if the outside Black group is strong.
This game is difficult.
With the diagonal there the 3,3 invasion doesn't work.
Pulling back there might mean he wants to play the diagonal move later.
He's thinking about the corner in the lower left.
White is playing very carefully.
The upper left is still unfinished.
Add a move to the top...
The game is far from over.
White sliding into the upper right is a big move.
Well...maybe there is something more important than the upper right...
Maybe he'll just jump into the 3,3.
The lower left corner I mean.
Then White will descend...it may not work...
Right. Play there.
Black cannot really invade the 3,3 point
Locally Black could live.
He should have a move to remove the possibility of Black invading the 3,3 point.
So he can take away Black's eyes and...
This also protects against the 3,3 invasion.
Black doesn't have any eyes at the bottom.
This looks effective.
It's hard to respond to this?
White wants to erase the aji in the corner.
This works too.
White can slide into the upper right.
In theory.
How many points does Black have?
I thought around 60 points.
What about White?
I think White has about the same.
That's the feeling I get.
He'll pincer the stone to protect the corner.
Now he has up to 65 points...
It's Whites turn now.
Now to play in the upper left and connect the stone.
I think White is a bit ahead.
White is going for Black's eyes.
He expanded his territory.
Black needs to play a move to make eyes.
Play a diagonal attachment in the middle.
That should about do it.
Making another eye is not difficult.
White would block his hane.
He peeped.
He wants to get out.
Light play.
A light move.
Now Black's peeping stone is totally captured.
Black still isn't clearly alive.
He needs another move.
That would make him stronger.
White connecting in the upper left corner is sente.
Black is thin in the middle. He could get cut.
He should connect somewhere in there.
It feels like we've seen the power of Kobayashi Satoru's reading and judgement.
Well, maybe I'm going overboard.
We still have to carefully watch what happens next.
Descend.
White doesn't have to work so hard.
Strange isn't it?
You didn't expect White to get so much?
I'm actually not sure how many points White has in the lower right.
Lower right...
It looks to be 8 points.
Black could reduce it to 7.
This is good news for Black since this worked.
Big move.
Connecting on the left side is also big.
Jump and connect.
For Black, the hane at the top is also big.
Force with a peep...
Settle the right and then connect.
For the most part I think I can calculate what will happen.
There are a lot of subtle things happening on the board.
Black extends...
What about White?
Does White play in the middle part of the upper side?
I think he should've connected at the star point.
This is an interesting move.
What does he do from here?
It's hard to say if it's a good move.
He won't be able to cut off White's group.
White can connect in the middle.
White needs to connect underneath on the left.
White wants to connect at the top in sente, but probably can't.
This part is difficult.
Now hane in the upper right corner.
The shape should be finished.
This was really great for White.
Black has quite a bit of territory.
Is this the best way for White to play?
Is it a close game?
Yes.
They're playing fast.
Well they may have it all worked out already.
There are so many subtle things going on.
Up until now...
things have progressed as I've expected.
I'm not sure what the correct endgame sequence is for the lower right.
Do you block here?
Will White be okay?
If Black just connects then...
White gains a little bit, doesn't he?
So then, don't connect, do something else?
I wonder if there is another move.
You want to do something.
There are subtleties to this. I'm not sure.
Oh, let White have the next move.
White will then...
He might show some fighting spirit...Oh, he blocked.
Back to the hane.
Kobayashi Satoru must have calculated that White is ahead if Black connects.
Black could have really paid for that.
White didn't do anything.
Black just connected so nothing happened after all.
The lower right...
I calculate it's worth 8 points.
Black gains one point.
7 points?
Black gains one point White loses one point.
Black hanes on the first line and then connects.
White can now atari.
White can do that but he needs another move.
It's sente endgame.
He haned.
Is there a move to get into the center?
This is big too.
So now White will play in the upper left.
Hane on the first line?
The next big move is...
Yes.
For Black the 1,3 point...
I think he has to hane.
Most likely.
There it is.
Is this a special move?
He has to hane.
Now for something worth 2 points.
Yes.
2 points in gote.
That'd be best.
The "ate" on the 5th line..ah?
Ah, I see..
White doesn't need to add a move on the left side.
Now it's just dame and playing inside the corner.
The move would finish things. It's not super important right now.
It's not a big problem, but it can get confusing when you think about it.
White's territory in the middle has been reduced.
Well, playing the ate, then the atari, and then connecting. There's nothing wrong with it.
Atari and then reduce.
No mistake.
Now the way is clear for Black.
Cut, and then connect.
Earlier I was worried it might not work.
Black's group on the bottom is low on liberties.
That could mean territory for White.
Yes.
Ko fight?
White played in the upper left.
Half point ko.
Does White have more territory?
Not yet.
The lower left...
How many ko threats are there in the lower left?
The lower left...
So whoever wins this ko wins the game?
Feels that way.
In the lower left...
The lower left?
Crawling near the 3,4 point komoku stone...
They could be...(ko threats?)
I think so?
The number of ko threats is important.
I feel that Black will win.
Peeping is better.
So peeping is better, huh?
Is it the best move?
If it works the peep is better.
After pushing..
That's right...
Black wins the ko.
White has ended the ko.
White...
White backed down.
Connect.
The rest is just dame.
35 to 41.
Cho: I played an awful move.
After 263 moves, Kobayashi Satoru 9d wins by half a point.
Kobayashi Satoru 9 dan has won by half a point, playing White.
Looking back at the game, any thoughts?
It looks like Kobayashi Satoru counted very well.
He just let the ko go. He knew who was leading.
This really was a great match.
From the beginning there was a running fight.
White settled in the lower right corner.
After that he didn't back down.
He kept his lead up until the very end.
Yes.
The game was great.
Cho might be really upset at his mistake, but up until that point it was very close.
This was a half point game.
Kobahyashi 9 dan pulled it out in such a close game.
Thank you for commentating.
Today's result, Kobayashi Satoru wins by half a point and proceeds to the third round.
We hope you look forward to it.
Goodbye.
Today, "my move" is move number 62.
Looking at this board position, White is under severe attack.
My opponent left an opening.
I was aiming here to fight back against Black.
Black tried to protect.
So I played here, aiming at this vital point.
This one two combination worked very well.
Then this...
Then I pushed and cut.
I can't say that the game was good for me here.
I managed to get out of a very tight situation.
