Hello everyone.
This is the 65th NHK Cup televised Go tournament.
I am the moderator, Nagashima Kozue.
Today is the third game of the first round.
A block.
Cho Chikun honorary Meijin vs. So Yokoku 9 dan.
Please enjoy.
After the nigiri, So Yokoku 9 dan will play first.
Komi is 6.5 points. There is no main time. Moves must be made within 30 seconds.
However, each player will be given ten, one minute periods of thinking time.
Good luck.
Now to introduce the players.

Now to introduce our commentator.
Ishida Shuuho Honorary Honinbo.
Thank you for coming
What will be the highlight of today's match?
Well Cho Chikun...
He can play any which way...
His strong point is that he can live with weak groups.
As for So Yokoku...
He played a really interesting opening with Cho U 9 dan.
Yes we were there for that.
Definitely was an interesting opening.
They're playing pretty fast.
The game has progressed pretty far.
So Yokoku is an active player...
The main point will be how Cho Chikun reacts to that.
He's used a period of his thinking time.
They could stand to make use of their time a bit more...
They played all these moves in no time.
The game has gotten to this point in a hurry.
So the game has progressed...
Very fast.
Let's talk about the lower left.
It looks familiar, but somehow not.
Yes. Is it joseki?
I don't think you can call it a joseki.
He's used one period of thinking time.
Now White just played the hanging connection.
The hanging connection...
It's the thickest move. Double hane was also possible.
Now will black push out...
White will turn on the 5th line.
It's the normal move.
Shoulder hit.
It's a move we've seen from Alpha Go.
We see this shape a lot in pro games.
It's a move that limits White's moyo on the left side.
White has to choose between pushing and crawling.
Let's look at the left side...
Black played the high double pincer, and then White attached...
You can jump into the 3,3 without hane-ing.
If you do that...
You can play here or here.
Black can hane. It's what was played in the old days.
Extend, then attach here...
Slide.
Turn. This is a commonly seen shape.
To continue on from here...
Here, and then this...
It ends up like this.
With these 3 moves White has gained a bit.
Up to here is solid.
That's the reason why...
Some would question the shape.
You can also attach.
Connect.
You can connect here.
The cut looks scary, but...
Of course, you can counter attack by cutting.
This fight is good for White.
You have moves like this in response...
White could play the bamboo joint.
You can double hane here.
Here...
Extend then cut.
Black loses the capturing race.
If you play from here...
Now there's a cut here.
Ah, the ladder is important.
Like this, you can cut here.
This is bad.
If you cover from this side.
There's a star point stone here.
I wonder...
The ladder is good for White.
That means double hane was possible.
He played solidly and played a hanging connection.
White played an easy to understand move.
He didn't fight back, just defended.
Black could cover, but then Black would be very busy.
He pushed...
He crawled.
Jump. Pincer
Attach.
They played this out very fast.
Will he cut or come under?
Locally speaking...
this is a joseki.
Looking at how fast So 9 dan is playing...
he must have really prepared beforehand.
I don't know what preparations he has made before hand.
For White, the normal move would be to connect.
Black would normally turn.
Cutting into the corner is also possible.
He'd take the corner.
Somehow...
So 9 dan
We can tell from the fact he's playing a fast opening...
he's inviting White to attack.
Cho Chikun might just do the opposite.
Geting attacked by the honorary Meijin.
This is the 43rd time he has entered.
Yes, the 43rd time.
How much longer will his streak continue?
Something to look forward to.
Extending at the top...
I'm wondering about it.
White has to worry about Black attacking at the top.
What would he do then?
He capped.
This makes it more difficult for Black to connect?
Is that the meaning?
Black's group at the top and his group on the left...
This move means he doesn't want them to connect.
Well ever since Alpha Go...
it's been a year or so since it appeared...
or something like that...
In a way...
Alpha Go's win has put professionals on notice.
It's play style...
It plays for the center.
He wedged....
Interesting.
It's common to wedge in between a one space jump when there is no capping move.
Black wants to come out...
White connects, Black connects...
The placement of White's capping stone...
Well...
Black's shape is a hanging connection now.
The bottom part is.
Then when Black connects...
The capping stone...
Well now that we're here...
White has a cutting point at the 3,4 point.
Black can cut into the corner.
Yes, cut the two stones.
Hane here would be normal...
The 3 White stones that are connected...
You can't say they're connected to the stones on the left. There are cutting points.
Right, there's two.
He could get cut in either spot.
Cutting right away would work.
After he cuts, we'll see how the game progresses.
Yes.
White wants to try and attack Black.
But White has cutting points as well.
How will he handle it?
Can he attack?
He doesn't need to think about spending a move to fix the cutting points though.
It'd be slow for White to simply connect to fix it.
The four stones at the top..
when they're inevitably cut.
It should be simple to survive with them.
From the way he placed the stone you'd think he was angry.
The next spot to play is the 8,4 point.
White will block. Black can force his way out.
Right, to separate White.
Black's group in the upper left could live at any time.
He decided to press down against White. Feels a bit cheeky.
This move came out pretty quick.
First this, then White pincered.
You could protect on the 4th line.
If you make White defend on the third line...
he decided that was good enough.
Normally you hane.
Cut.
Now block here...then this....
Connect.
Hane here. Now there is this cut.
Simple to capture.
The ladder doesn't work...
Maybe it does?
It works.
That means that Black cannot play that move.
When these stones get stronger...
the value of cutting here decreases.
Let's talk about when the cut would be valuable.
Black needs to be strong at the top.
When this is all played, now cut...
Connecting is difficult.
Now it's miai between getting captured and connecting out.
He might come from the other direction.
If he plays like this...
It'll take some time for this to get out and become safe.
White is the one getting attacked.
They're both playing with their opponent's cutting points in mind.
Now we'll see how this fight will turn out.
A professional wouldn't think about just pushing out to the center.
You are talking about the wedge?
Right, it'll never be played.
What does Black do after White connects?
Covering from the outside doesn't work.
There's a ladder.
The most natural move would be to connect on the 5th line.
Yes, where there is a cut.
Protect his cutting point.
If Black let's his guard down...
Black will have to worry about making eyes with his top left group.
So now White can atari and force Black to connect.
White will play the knight's move along the top.
Black's group in the top left may die.
When White ataris...
the shape could turn into a ko.
Black can block off the top side.
After White takes, Black plays the 7,3 point.
Cho Chikun is thinking about how to handle that.
We know what happens if White plays this and Black plays here.
White gets out.
Black has nothing left but this cut.
White can definitely escape.
Black is dying.
That's not an option.
What happens if Black decides not to connect.
and instead blocks?
Then when White captures, Black plays here.
If he cuts he lives.
If White connects...it's a ko.
Black can make use of the ko.
Black takes, then White answers.
Black blocks.
When White takes...
Play in the corner.
One more move here would live.
This sequence is a possibility.
He played atari.
There's a high probability that the sequence you just saw will happen.
The beginning of the game had a good pace.
And now, all of a sudden, we're at a point where they'll need to negotiate.
The Black group in the upper left....
it won't be easy to get that to live.
Black has ko threats.
White could connect and let Black live...
That would be unpleasant.
However...
We'll see if he fights out the ko.
He didn't fight out the ko.
He captured.
Well, taking the stone...
If White gets cut...
White's group on the right won't have to try and escape.
Is he going to play the 2,2 point...
or is he going to just capture? He's having a hard time deciding.
Will he go here, or over here?
Speaking of this move...
If he had connected..
when Black cuts here...
White descends, and Black is not unconditionally alive.
Which means Black comes here.
So that means it's better for this stone to be here.
Right, Black can squeeze White's liberties.
This is the difference.
Hard decision.
In the game he took.
When Black cuts here, you can see the eyespace here.
He definitely has eyes.
But, I think he could've connected.
So Black is deciding whether to cut or play here.
Yes, the 2,2 point.
Ahh, there.
White might grab the 2,2 point.
Ataring the 3 stones is sente. Cutting there is sente.
Actually...
Well, I'm not exactly sure.
Normally White should play on the 4,5 point.
Right next to where Black just cut.
This is tricky.
If he plays here, then atari.
Connect. Cut and capture.
This is definitely sente.
Will White pick this sequence?
White got cut in sente though.
He could play here.
This is patient. Then connecting here is definitely gote.
Black won't connect here.
Will he choose this?
The 2,2 point.
This would be pretty big.
That move is also effective.
Peep?
He peeped.
Getting cut in sente would be painful.
He'll connect.
He jumped.
He doesn't care about getting attacked.
When Black pressed the left side White group down...
Will he connect?
Well this has gotten interesting.
In other words...
Black can push here or cut. They are both possible.
These stones are very important.
If Black connects...
You can say that Black has been forced.
White could have peeped here first.
He must connect.
There is a possibility Black will push out.
He cuts...
Now this move is terrible.
This is quite tricky actually.
So therefore he covered.
He cut.
What is he up to?
Just connecting is not good.
Playing this means you didn't want to connect.
Right.
But then, what do you do instead? You can't just leave it.
Pushing in is an option.
At the head.
He covered again.
This is, of course, not a net.
He can push through in a lot of places.
White can push once towards the center...
Then cut off the three stones.
He wants to keep his left side group safe.
He got to this spot first.
He has to play the 8,2 point. He has to cut and capture that stone.
If he doesn't the corner will die.
So after this...
White will play on the 6,10 point...
Then advance towards the right.
Black has to block.
When he gets cut...
Then will he connect on the outside?
What will he do?
Will Black squeeze to cover the outside?
That way he can get thick?
He loses quite a bit of territory.
The question is whether or not it's a good idea.
So this was his aim.
White's group in the lower left...
He wants to make use of it.
His next move is tricky.
He should atari once.
White can hane underneath with his group on the left.
That would make it mostly alive.
So he's not too worried about eyes?
I don't think he's worried about eyes at all.
Let's talk about Black's group on the left.
For example, let's say they exchange this.
It gets captured in a net.
Kozue: This...oh right! Shuuho: Nothing to worry about.
Of course since there is a stone here...
the ladder is good for Black.
The atari...
is hard to fathom.
If you want to do something with this stone...
he definitely won't connect, he'll come over here.
Then here.
You lose this part but this part gets surrounded.
However with this, the shape is mostly alive.
There is room to live.
This looks like an approach move.
He'll throw away the two stones at the bottom.
and aim for cutting the left side.
He might be angry.
Cho Chikun.
This might be overplay.
He must extend.
Now cover.
Knight's move.
He should've just peeped from the beginning.
Now if Black were to connect...
If he extends the stones he just extended out will be captured.
He can't connect.
He could jump to the 5th or 6th line. Plenty of options.
Whichever he chooses, the stones should be fine.
Wow, what a move.
He jumped.
He is absolutely not allowing the cut at 7,11.
He's trying to protect his cutting points.
If White just cuts...
He'll move the two stones to the left.
Just now, had White played like this...
for example...if he jumps here...
Come out.
You have to come out.
If White cuts here...
If Black pushes out, White has this atari in sente.
Pushing out is difficult.
It's possible.
This move feels better than this move...
with respect to the cutting point.
Yes, if he comes from that side.
This stone is going to have a hard time getting out.
If he covers...
throw away a stone...
White can seal in Black and probably live on the side.
Kosumi.
Normally this would be unthinkable.
It probably just came to him.
This wouldn't happen usually...
Locally this is bad.
He'll take the left side and then figure out what to do next.
White wants a fight.
These two cuts are miai.
If he plays like this and then White gets out...
Letting these two stones get captured is unthinkable.
He must play there.
Cover.
Black's move.
Nothing feels right.
Taking here is sente.
So somehow nothing feels quite right?
It all depends on what is played.
Well let's say he adds a move here.
Black will play here...and we'll see what happens with White.
He could play over here first.
Telling Black "Go ahead and live please." He might do it.
Here?
He connected.
White has his work cut out for him.
Does White capture the two stones at the bottom...
or come out on the left side?
Hard decision.
Let's get back to what we were discussing before..
This variation.
When White plays elsewhere...
Like this then here.
The tail end would get captured otherwise.
Like this, atari is sente.
If he plays this, then this will happen...
Black might be able to make something out of this and White will die.
That means White will need to take care of this side.
If this happens, White probably won't play over here.
That's Black's plan.
Well, whether or not White captures...
This would be terrible.
Black is now captured.
He played from the three stones.
White played on the left side.
He's betting he can make life at the bottom.
He gets the left side though.
It's quite big.
So far, Cho Chikun hasn't been playing according to his style.
This is much more like his style.
Making life at the bottom.
Well, no choice.
After he seals..
He definitely won't try and save the left side.
After he gets out on the bottom.
This is a bit scary for White.
The bottom is worth a lot of points.
Can't be helped.
White will atari, Black will cover the outside...
Then White must add a move at the bottom.
I think he might attach at the 3,3 point.
Black will attack the bottom.
The bottom isn't comparable to the left side though.
When White is attacked on the bottom...
he should be able to pull something off.
Well, we'll see if he pulls something of at any rate.
This is atari.
Cover.
If White plays elsewhere the left side will be in danger.
He must add a move.
He can hane...
That would be normal.
The pincer attachment is also possible.
Well there's still a bit...
...of aji leftover.
It'll turn out okay.
It's hard to say if he's 100% okay.
5,13...the diagonal attachment...
Well, there it is.
The game will focus on Black's attack and how White will survive for a bit.
White will move out at the bottom?
No choice but to.
He might attach.
No.
He thought playing too close would make things difficult.
He can reduce.
The stone he just invaded with and the bottom White group...
If they connect then White can make life.
For example, if Black attaches above.
He definitely won't play that though.
He won't let White connect.
If the bottom gets captured...
then will White turn his attention to the right side...
and try to reduce it?
Here he should cut.
His move just now...
is it good or not?
The kosumi attachment was better.
This doesn't feel right?
He'll be happy to just...yes, atari is good.
Ahh, I see, if he cuts, then Black will extend.
Throw away two stones.
White would lose eyes.
Well, whether or not White is alive is a separate issue.
If Black connects.
White just has one eye.
The capturing race...
He's playing as if there is no way he'll lose it.
Whether that's true or not I'm not sure.
If White gets captured, Black is alive...
Black would live.
If he adds one move to seal in the White group on the left side...
At the 5, 13 point...
It'll be perfectly placed to take away an eye.
But, if White gets to turn then Black might not survive.
Black needs to grin and bear it and block from the outside.
Play here, and then cut here.
Then play here.
If he does this...
Throw in.
This is no good for White.
White has fewer liberties.
Like this?
Next is this.
Here.
Even if he takes away a liberty here...oh? This might work!
Here...
Black hanes.
3 liberties here vs. 2 liberties.
Here...
He can peep.
White loses.
If he loses he loses. He blocked.
Is White really secure?
He played here in the game.
He has to try and capture.
Playing here to capture won't work.
The capturing race is totally different now.
Black cannot win.
Black plays something here.
He probably won't try and capture.
He's definitely not okay.
White loses the capturing race.
Black descended immediately.
Capturing two stones may not change much.
White should be... (Kozue:) Is he okay?
It's impossible for White to win the capturing race.
Cho Chikun is mumbling to himself...
Black plays ate-komi...
To try and win the race you have to play here.
Block.
Now...
Just for example...there's a lot of different moves.
Hmm, instead...
This is easy.
Squeeze.
Connect, and then White captures...
Now it's over.
White only has 2 liberties.
It's impossible for White to capture Black.
Cho: This won't work.
For the capturing race...
he's trying to lengthen his liberties...
In any case, the vital point is the vital point.
The best White can hope for is mutual life.
That'd be a great success for Black, since his stones were dying.
Mutual life would be fine. But, I don't think that will happen.
I see.
Instead...
Exchange this for this.
Whichever direction is fine....
You have to take this liberty away.
This works. Black wins the race.
Even if he takes a liberty away..
As long as Black doesn't make a mistake, White dies.
Up to here.
If he makes a mistake, it could become mutual life.
Take away a liberty.
Now throw in.
Then descend.
Cho Chikun...
did he make a reading mistake?
When he ataris the four stones..
Ataris the 4 stones...
If he descends...
He might play along the side.
When the 4 stones are atarid...
What the heck is this?
There it is.
He must connect.
When he descends...
He has to take away liberties with something, like a kosumi.
Black, that is.
So the problem is whether or not this is mutual life?
He has to find some way to make it mutual life.
That's what he's wishing for.
Black gets sente.
He gets sente. Very bad for White.
So let's say he descends.
If you capture then White loses.
So like that, Black would win, so White must play here.
Take away a liberty.
Now take away a liberty here.
Black loses.
Yes, one eye vs. no eye.
If Black makes an eye.
Make an eye here.
Mutual life in sente.
Keep going.
White takes away a liberty here.
Black gets to live in sente.
Terrible for White.
IS this the best White can hope for?
This is all he has.
We'll see if he can pull through.
He's looking carefully.
White just connected.
Does Black have anything else?
Black should descend.
White doesn't have time to capture, so here.
If he plays straight away here then no eye here.
Black would lose.
That's no good. So...in the end this should be mutual life.
This is mutual life. There's no other options.
White has to grin and bear it.
Black can't capture White.
Well, White showed us that he could persevere.
Is there a way to win unconditionally?
Is he thinking about the hane?
He used another period.
We talked about the descent. If he plays the hane here...
If he ataris...
Which side should he atari?
Oh, well that's the same thing in the end.
The hane is a bad move.
If he plays that...
he can turn this into a ko.
So don't descend, here...well, maybe here?
Block
Here.
Throw in.
If you want to take away a liberty here you have to capture first.
Play here...
You don't have the liberties to play here.
White has to capture first.
It's a ko now.
He takes and now here is the ko.
He descended. Shuuho: He thinks mutual life is good.
He needs to make an eye. If he doesn't, he'll be the one who gets killed.
From Cho's perspective...
he probably feels like resigning.
Well, play a bit more.
This is mutual life in sente for Black.
Black's center is really strong.
Just when we thought the left was going to be White's territory...
White instead got attacked.
Black is totally in the lead.
This is speed Go. No telling what will happen.
He can't play elsewhere, he'll lose.
He needs to make certain he removes liberties.
It's important.
He has to throw in.
So now the White territory on the left, the upper left, is about 30 points.
Yes, 30 points.
Actually he lost 30 points. Before, it was about 60.
Black gets to live in sente.
There was a chance for mutual life in gote.
But he gets sente.
White feels like he wants to just resign now.
Not yet.
He might start a huge comeback.
He'll go for the stone in the lower right, I think.
He solidified from the left side.
Things haven't turned out in White's favor.
He can't let these 4 stones go, then there won't be mutual life.
He just needs to protect them.
You'd want to sacrifice them, it's just 4 stones.
Those stones are important for mutual life.
He didn't connect.
He can't let his guard done. If he gets cut...
Black will be in big trouble.
White's aiming for an all out fight.
If Black cuts, then extends towards the center...
The cut is impossible.
The cut in the middle is big for White.
White has his eye on it.
He still can't cut.
If he gets cut..?
Black's position is a bit scary.
He'd like to just extend to prevent the hane.
Well, I'm still worried about the middle.
The natural move would be to hane at the tengen.
Just as I thought, he played in the middle.
White has to move out with his group at the bottom.
He just came out.
If the two White stones at the bottom
could connect with the rest of the group above them...
that would mean White has a way out.
If that happens..
Black's group in the middle would not necessarily have two eyes. There would still be more game to go.
The whole group would be affected.
Black's entire group in the middle...
That is what White is aiming at.
He's going on the offensive.
It just looks that way.
White can attach at the 3,3 to do something with his stone at the bottom.
That area is not 100% Black's territory.
If White can manage to finagle something using Black's group in the center...
like if White can somehow live in sente..
White will attach at the 3,3 point in the corner.
If that happens...well...
The game may be far from over at that point.
White is trying to split Black's middle group from his group at the top.
Those 4 stones at the top. Kozue: Yes, he's trying to surround them.
Using the approach stone in the upper right.
He wants to take them all.
White has nothing to lose.
This situation is scarier for Black.
The game is good for him.
A fine move.
Solid.
Black's group in the center is the most important thing here.
Will he peep once here?
All of a sudden...is Black in trouble?
If White can make use of the two stones at the bottom...
making two eyes...
He's not totally dead.
He'll probably connect near where White just peeped.
Right.
Even if the game is good for him...
Two two White stones at the bottom could be cut off with a kosumi attachment or a knight's move attachment.
White wants to protect but...
Will he have time?
So if Black attaches on the star point at the bottom...
he can cut.
White can just do whatever.
If he jumps at the 14-5 point...
above the stone where White approached..
He'll attack the 4 Black stones.
Black is playing calmly.
White can't just play elsewhere.
His group at the bottom will be captured.
So capturing the stones at the top is not an option.
"Please, go ahead and connect."
White cannot save his two stones at the bottom.
Black should live now.
Now, the action moves to here.
So after he makes a few exchanges here...
he'll want to switch to the top to go after the 4 stones.
He has to try it.
There's a lot of ways to handle this.
He could hane on the second line.
No more thinking time for either of them.
He could attach here or here.
Black could descend, and now it's hard for White to sabaki.
So he played here.
If Black blocks then White cuts.
The hane underneath is also possible.
White can make sabaki.
This is a possible move.
Black can't let White make sabaki and then let him have sente too.
But maybe Black can't help but take gote.
If White plays something over here...
Kozue: It looks like they're captured. Shuuho: That'd be pretty bad.
Black needs to play at the top.
Black wants sente to do it.
What's important here is how will White sabaki and who will get sente?
Very tricky situation.
Well...
he's going to take sente no matter what.
White can extend from the stone where he played the attachment.
Black will play elsewhere.
Black will cap on the 5th line at the top.
Cho mumbling:No time left
He had no choice. Letting Black cover would have been bad.
Black can play elsewhere.
Capturing White in the corner is pretty much impossible.
Play it out a bit more eh?
He might hane at the 15,16 point.
Hane the two Black stones.
From the left.
Oh, he attached.
Normally attaching like this isn't good.
Depending how Black answers, the stone he just attached with might get captured.
Is he aiming at a severe move?
White won't let Black connect no matter what.
Black played the hane underneath.
If Black gets captured in this area...
He'd lose.
White blocks...
Then White plans on playing the tiger's mouth from that stone.
Is Black's group at the bottom in danger of being cut?
Black can protect.
Black is thinking that White's outside group could get weak.

Cho: 'Always 9, 9 ,9...'
It would be kind of pathetic if...
if Black''s turned directly from his two stones at the bottom.
At the point 15,16.
White could cover and Black would cut.
He's not going to do that.
It looks like a capturing race with White's outside group.
Maybe White doesn't play the tiger's mouth...
Maybe play in the middle...
On the 4th line..
Black might play the kosumi attachment.
White could try and save his two stones on the left.
Even if he does save them...
Even if he could save them it wouldn't mean that Black would die.
Now we're watching the deciding battle.
Black should connect here.
White can play on the top.
At 15...
Maybe he can push out some and push out...
He could play at the spot to the left of the star point.
It would then be a capturing race.
White can't win it.
He has to find a way to make use of it to survive.
I don't get this move.
He has to hane in the corner.
White will block...
Like a hane?
Then he'll block along the side...
White went there.
So White pushed and then Black will turn.
Then White will try to capture the corner.
If White wanted to try to connect under at the bottom...
White's hane seems to be sente.
White's hane on the second line, right?
It would threaten to prevent Black from connecting.
A hane here might kill everything in the lower right.
He'll hane in response.
White is alive now.
When Black connects under, White can cut.
Black can atari and then connect under.
White can then hane on the right side and descend.
White did a good job here.
Black's connection on the first line is thin.
The peep at 16-19 is gote.
There is a cut at the spot where Black connected underneath.
It isn't dangerous for Black.
May as well add a stone there.
So does White feel like he's in a bad situation?
Well he's not desperate.
There's still some hope.
White did reduce quite a bit of territory.
This isn't going to give him any more liberties
This capturing race is good for Black, right?
I don't think White can live in the lower right in sente.
Looking at the two White stones on the side there...
Black can block them off.
He has to or he'll lose the capturing race.
He played above.
The center just keeps going back and forth.
Wow.
Really thrilling.
He's going to try and capture...
Is he going after White's eyes?
I think White is pretty angry. No joke.
Black won't die.
Being forced to make eyes is painful, though.
But, White doesn't have any eyes.
After a few moves he will.
However, he can't just make life directly in that area. It's hopeless.
Hopeless, again?
Cho: Oh god that was a bad move!
Black will block...
He has to. If he didn't he'd have lost the capturing race.
White needs to make use of Black's group in the lower right to make eyes. He can't live otherwise.
Does he need to do something against Black's outside group?
Well, it comes down to whether the two White stones can escape.
That probably won't work.
He should just take away a liberty from White's 3 stones.
Black can play on the outside...
Black wins the capturing race.
Cho Chikun's mumbling makes it sound like he's in dire straits.
Well, that's how he really feels.
Is it sometimes not how he really feels?
He's in a really bad situation.
White can live.
It has to do with the cut he played earlier.
He's really desperate to live.
What an awful move...
So right above the star point there's an eye.
He can make an eye there but he needs to guzumi (make an empty triangle) first.
Professionals hate making empty triangles.
If he doesn't make an empty triangle he'll die.
The empty triangle makes use of the cutting stone.
If Black let's him cut through he collapses.
So he won't be able to make use of the cut.
As expected of Cho Chikun...
He's only thinking about living.
Which means...
He has no choice.
Playing that is painful.
This is threatening to make use of his one stone there.
If he leaves this cut open...
He must live. Well, he can extend once.
After Black connects, he'll need to add another move.
I don't think he's going to sacrifice.
Black could capture the White stones in the middle.
He probably won't and will switch to the top.
Who knows?
No helping it.
Black capturing the two White stones is big.
How will he protect the top?
Black could play the tiger's mouth.
He could naturally capure that way.
Capture all of the White stonesin the middle.
Yes.
He's buying time.
Black is thinking hard about what to do next.
With this...
Extend..
Capturing the entire top side is really big.
Looking at the move to descend at the top side of the board...
I think he'll play it soon.
On the first line? White will get there first..
Black could hane there.
Play it now.
It's sente for both players.
I don't think White can block if Black hane's there.
He won't be able to defend against the cut.
White hasn't given up on the group in the middle.
He wants to connect to try and get them out and make a comeback.
He won't let him come back.
This is unexpected.
This might be decided by territory.
Next on to the top.
Right, there it is.
He might hane on the left first before protecting.
He'll make one exchange.
White has a lot of territory at the top.
Black has the bottom, the middle, and the right side.
Connect at the 3,4 point...
The cut there was a good ko threat.
Leaving the threat there may have been big.
White has 70 solid points at the top all together.
It's comparable to the bottom.
Sliding here is big.
He's going to play the hane in sente to seal up the open area on the right.
The right side is secure.
Then he could play the 3,3 point.
If Black gets the 3,3 point, he'll be in the lead.
Black has the right, the middle, and the bottom. That's huge.
Black will kosumi in the upper right, and provided White can't break through in the middle...
Black wins for sure.
White can't break through.
Yes, there it is. The kosumi
White has 70 points if you count up everything.
Even if you just forget the right side...
the bottom and the middle are enough for Black.
White's moves in the middle are all White's right.
Black is winning.
Can he cut here?
He can push above that...
Doesn't work.
White cannot break through.
He should see that here.
He left it alone. He can't do anything.
White can play the empty triangle. It's White's privilege.
Not many places left to play.
They should be evaluating who is in the lead.
White can play the empty triangle and then extend.
He can then connect his stone in the upper right.
This is all White's privilege to play.
Are they going to play it all out to the very end?
Not many places left to play.
Turn in the center...yes...
Yes, the upper right.
It's 3 points reverse sente.
Now the next biggest area is the lower right...
The end game will be quick.
The shapes are all basically set.
There's a few moves left.
White can play ate-komi in the upper right.
Black can connect...
White can make a point, and now to the upper left, where there is a half point ko.
This is the half point ko.
Black connected.
Game over.
They both have big territories.
Black's territory is bigger.
Black captured a lot of stones.
Black really wanted to capture those White stones in the lower left, rather than just get mutual life.
It got dicey with the threat of the cut, just for a moment.
60 points.
49...
But...
White tried his best.
After 244 moves, So Yokoku 9 dan, playing Black, wins by 4.5 points
So Yokoku 9 dan playing Black has won by 4.5 points.
Looking back at today's game, what are your thoughts?
Black made sabaki here in the lower left.
He haned and came out to counterattack.
Black managed to make points.
And then there is this capturing race.
Black took sente, and the game was over.
After the lower right, White might have had a chance.
It got complicated.
Well, the cut here.
Cutting became a bad move and this was a huge loss.
Cho Chikun had to really think hard when there was the capturing race here.
He really tried his best.
The game was decided quickly. An interesting game.
Ishida Shuuho Honinbo, thank you for coming.
Now, let's go to the players discussing the game.
It was good you got sente here.
This helped him make shape.
There's a hane here.
This is almost dead.
It was so simple..
Wow.
Like this...
This.
Is this bad?
There's a ko here, so you have to do this.
I see.
This was a total loss.
I can capture these and throw these away.
Either is fine.
White is low on liberties.
You have to hane here.
Is there another move?
Huh? Yes, yes.
Black can resist.
I see, he plays here.
What happens with this?
Looks like White loses the capturing race.
This feels terrible.
This is definitely a ko.
You can't capture it straight out.
White's pretty low on liberties.
You can't get this whole side.
Man, this was stupid.
Just attach.
Cut.
Then here.
He'll block.
I give up. What the heck is this?
Is that so?
I thought this was annoying.
This doesn't work either.
This doesn't work either.
It's time to end the discussion. Thank you.
