Hello everyone.
Hua Yi Gang 8-Dan
I'll be commentating the LG Cup, semi-final match between Lee Chang Ho and Cho Hun Hyun.
Cho Hun Hyun's demonstrated his strong point in this game, which can be described as being witty and refined.
Let me quickly describe the content of this game.
6th LG Cup, semi-final match Lee Chang Ho 9d (Black) vs. Cho Hun Hyun 9d (White)
Up until the key stones, common plays are the approaches in the direction of the 3-4 point...
...or from here, high, or low or Chinese opening...
...or defending the corner.
In this game, Lee Chang Ho (B) approached from this corner.
This approach, we can't say that it's unplayable, perhaps it's just a form of experimentation.
On the upper left corner, a joseki was played.
After the joseki, a low approach...
...then a high pincer, both are normal moves.
Leaning-keima. This leaning-keima seems to be more popular recently...
...in comparison with this jump.
Now, if, Black crawls, White stretches.
Following this variation, you need to be wary of the possibility of a 3-3 point attachment underneath.
If White manages to attach on the 3-3 point, White would be pretty comfortable.
But I think it's unlikely that White can attach now, but has to first play around here.
In the actual game, Black pushed through and separated.
White's tsuke out of his position is a basic joseki.
Black straightforwardly embraces the White stone, very solid move.
If Black wanted to play more aggressively, he could have stretched.
If you stretch out, an aggressive style of play would be to follow here.
This is the normal joseki.
And there are others who descend here. This is Kobayashi Koichi's style of play.
If you dare block, then i'll jump.
The variations following this are too many for me to cover in detail during this commentary.
That stretch would also be an advantageous move.
But, Lee Chang Ho (B) chose to play solidly by embracing the stone here.
White played a hane here.
Another variation would be to atari...
...then play over here.
But on the opposite side is the opponent's star point...
...and there's a worry that the opponent will stretch out.
But if it's our star point, then it'll be more advantageous for us.
So White plays here.
This is Cho Hun Hyun (W)'s decision.
Let's look at how Cho Hun Hyun plays.
A keima here.
When Black follows up with a keima into the corner...
White will not kosumi here. That's a modern style of play.
White feels that a kosumi here is too small, when exchanged with Black's extension.
Because sooner or later, you're going to have to invade the bottom.
If you were to invade then, you're going to be live with a lot of trouble.
If that's the case, why not invade now?
White invades.
You have to pay the price too, as this lets the opponent kosumi.
You play an extension.
After the extension, this keima becomes very powerful.
Black will become quite uncomfortable.
Thus, Black kosumi.
Only then, does White atari.
After sente is achieved, the left side is now urgent.
Big move, that White must play.
If Black manages to check your extension, it becomes an extremely large move.
Black can only obtain either the top or right area.
Hun Hyun holds regard for the corner's significance and...
...immediately secures the point.
Black sees the hane and decides that furtively developing on the right would be risky,
so settles for defending the territory on the top.
Now, it's almost like when you played the keima, the opponent disregarded it,
and let you play the kosumi with sente.
And White, of course, has nothing to be dissatisfied with and is comfortable.
Jump.
So this for Cho Hun Hyun has been a very satisfying exchange.
Generally, this next move is considered crude.
But Cho Hun Hyun's Go is very practical.
He immediately peeped at the jump.
This is, a typical example of a crude move.
Crude moves are okay, just so long as it's effective.
This move, Black must block.
If Black doesn't block, and White crawls,
Black's mood is soured.
Subsequently, there would be all sorts of problems.
If Black hane, White's response with a clamp is possible anytime.
Black cannot resist by descending, as that allows White to run out.
All the territory would be gone.
And there are still other ways to play.
After there's a stone around this area, it's not impossible to just directly cut.
The aji is horrible.
So Black blocks.
White immediately follows up with a block of his own.
This block is also a very big move.
If White doesn't block, where will Black play?
Black will not crawl, but will play here.
This for White is quite painful.
If you block, Black will push through.
The situation becomes severe - do you dare to block?
If it goes like this, Black gets to play a sente move worth over 10 points.
This is worth a lot.
With the board so wide open, let us appreciate the situation.
For example, a keima on the right seems big.
This shape looks correct.
But this move should not be played now.
Even this keima here looks big.
Typically, this move is also worth over 10 points, but he blocked on the left instead.
Let us appreciate this. This move is very important, thus the emphasis.
Before the block, he played a clamp there.
Black definitely has to take action around this area.
If Black jumps, White will hane.
Gote move.
He plays a sacrificial move then jumps out.
White has no choice but to capture.
Capture.
Protect.
Black's play is also considered normal.
White presses.
White comes out.
Black reinforces.
Both players are considered to be playing normally, White's large chain of stones linking up to the left.
It's obvious now that the point of focus should be the right side.
Black cannot neglect playing a move and allow White to develop such a large piece of territory.
Tsuke. This is a strong move.
This is a reduction move, and also an urgent move.
If you were to invade at this point, it won't mean that it'll die...
...but if White plays a horizontal stretch out, you will get attacked...
...and the chance to develop territory on the top will be reduced.
This horizontal stretch is an urgent move.
Black must tsuke.
If we're just discussing about shape, if you want a firm and steady shape, then you should play here.
This descent can be considered a foolproof shape, a correct shape.
But, Black welcomes this move too.
If you were to play a wedge, Black will atari.
If you were to play below, you'll only get to increase a small piece of territory.
But by increasing your small piece of territory, Black also gets to gain some of his own.
So it's not a worthwhile exchange.
Let us see Cho Hun Hyun's response to this tsuke.
You can't descend, and you can't play a horizontal stretch either.
What's the difference between this and when Black was further away?
When Black was further away, White's shape is tidy.
But when Black's over here, when White responds like this...
...this shape, i'm at a loss for a proper description.
What shall we call this shape... I'm afraid we can only call this White shape...
A shape that wants to cry, but can't produce tears.
Even if you want to cry, you can't.
Why is it?
You can't connect, because when you connect, what happens to this stone here?
6th LG Cup, semi-final match Lee Chang Ho 9d (Black) vs. Cho Hun Hyun 9d (White)
This stone is going to go on strike!
You would not have shown respect to the purpose of this stone.
So this is definitely unplayable.
Notice, this hane is an urgent move.
You can't play here, nor here.
A hane on the bottom is worth even less of a mention, Black has many responses, maybe even this works.
You have restricted White to the bottom and now White feels very uncomfortable and difficult to continue.
Hun Hyun, in the actual situation, plays here.
If you were to stretch,
Black provides a typical example of a heavy shape.
This is a bad shape.
Of course, a stretch is possible, or a tiger's mouth connection.
Play an honest move and let this head move out.
And this also gives Black bad shape, making it heavy.
It also takes away Black's ability to create territory on the top.
So please pay special attention to this area as it's very important.
Appreciate the fight in this area.
So he also wants to hane, this is urgent.
Hun Hyun plays lightly and atari.
And sends you back.
This seems very weak...
...but it doesn't matter, all he really wanted are these 3 stones...
... and it seeks to reduce at the top.
This move looks as if it's trying to make life, but it's actually worth more than 10 points.
Also a very satisfying move.
Black has to play here.
If he doesn't, White atari, and after the capture, White jumps.
This shape is too good for White.
So Black moves here, in preparation for the atari and restricting White's movement.
Hun Hyun seizes territory.
Not only is this move big, White is now definitely alive.
It even aims to connect, and has foreseen that Black is going to atari here.
Even after the Black atari and capture, White shows complete disregard.
This is yet another very powerful move.
If you were to ignore this move,
White will play a covering move on the lower left corner and this area is settled.
This area has sizable amounts of territory.
So Black considering how to head out, is to be expected.
This move, after some consideration...
...it's possible, that even we play the most unbearable and crude move...
...and continuously kosumi out to the center...
...it still might be better than the move played during the game.
Let us see, in the actual game, Black played a keima here.
It looks very good, but when White plays a keima on the 2nd line, this is a good move.
After White presses, Black starts to feel a little uncomfortable, and cannot stretch.
If you do, if White pushes through, you'll be at a loss on what to do.
If Black retreats, the shape is good for White. If Black blocks, White may immediately cut.
Lee Chang Ho sees this, and realises he has no good moves left.
So he reinforces by jumping here.
White plays a hane at the head.
This move is decisive.
Black finds it difficult to continue.
And in the real situation, this was played, and Black heads out.
Some have asked, could this move be played, but this move has problems.
Seems as though it's faster to head out this way, but when White squeezes,
then when Black connects here,
or maybe this move.
After the White atari,
And with the White retreat here...
Notice, where is the weakness in this shape?
If there is a tiger's mouth shape, you don't push through where the "mouth" is.
You come through from here, and now Black's position has soured.
What can Black do?
There's a wedge coming, and if Black connects,
when White pushes through,
the eye space is gone.
In other words, when White retreats, it's sente.
All you can do is atari, and there's nothing to be proud of over there.
So why not, play like what was played in the game...
This was the move in the actual game.
This move shows the essence of the preparatory move made before.
This sort of move is where Cho Hun Hyun is strong beyond compare.
He attached here.
Let us think about this move.
If White were to just push through like this, then Black would play like this.
But with the attachment here, if Black plays over there, it's meaningless.
With the other move, is it even possible?
Obviously, it doesn't work.
So this attachment here, is a great tesuji.
White destroys Black's shape by pushing through.
Look at how formidable Hun Hyun's moves are, even this area here has grown some flesh!
He played beautifully.
Black has no choice, but to just keep moving.
Jump out, and look towards attacking here.
White plays at the point of territory.
Black has to atari.
Hun Hyun plays decisively and exchanges the stones...
...causing Black's shape to become awry.
After Black atari, White doesn't even capture out of convenience,
And plays a decisive and interesting move.
With this lone move here, Black has to take some action.
It has to prevent White from having a keima like this.
This is a vital point of growth for both sides. White has a big move.
If Black has to protect this territory later on, it'll be unbearable.
When Black plays there, White isn't too displeased, and plays a reducing approach move.
Hun Hyun plays very well here. And he starts to reduce.
Black presses, White doesn't reinforce.
This hane, Black doesn't dare to cut, because after a few moves, Black's lower left will still not be alive.
So Black would rather play here.
White surrounds the territory in the center.
This causes Black to make life.
This is a harsh move, threatening to throw in immediately and cut the stones in the center into two.
He played there, forcing Black to play below.
It goes without saying that White gets profit in the center.
Hun Hyun's started the end game, by straightforwardly reducing here.
Both players started an intense battle here.
Escape.
Jump.
No choice but to push through.
White doesn't want to lose sente so peeps first to retain sente.
Both players played out a tiger's mouth.
Pay special attention to the shape here.
Black's shape seems thick and seems to be attacking White, but if he tries to connect, it doesn't work.
This is because when White plays there, it gets sente.
So when Black plays here, it fails to connect.
Over here, it's the same, it also fails to connect.
If you really wish to connect, you need to play a crude move over here.
But this shape looks heavy, and the opponent gets to move into your territory.
After analysis with my teammates, we feel that Lee Chang Ho has no choice but to atari here.
After the atari, White has no choice but to protect around this area.
Maybe there's a cut here, but I didn't examine this in depth.
Lee Chang Ho's actual move is definitely problematic.
He bended over here.
After White stretches over here, Black's game starts to deteriorate further.
After this move, the stones in the center develops more and more problems.
You have to protect.
He will cut quickly.
Subsequently, this group of stone's liberties will look tight.
Above, there's also a possibility of an atari.
So there's no choice but to connect here.
Cho Hun Hyun's move here has some problems.
He attached.
You wouldn't dare to push through.
This was played first, this is a good move.
After this move, Black's group of stones in the center gets captured by Hun Hyun.
This attachment is useless.
White plays an honest connection.
If you stick, you'll get blocked, unsatisfying.
White captures.
Only then, does Black connect.
Notice White's play, as it's only then does White capture this stone.
Take out.
Cho Hun Hyun's fight here results in gaining of the center and the loss of 4 White stones on the right.
But overall, White has gained a large advantage.
White hane when Black retreats.
Black needs to surround territory, so he surrounds it here.
This peep here is delightful.
Black doesn't have anything to trade for this.
The key here is that White still has the chance to keima into the territory.
Black has no choice but to play there.
Only then does White reduce here.
Black has to retreat.
White hane again.
Black resigns here.
After a resignation, observers like us need to analyse the situation.
How much of a difference in points was there?
The conclusion was, just based on the board, Black clearly wins by 4 to 5 points.
This LG Cup competition, Black has to give a komi of 6.5
So White should win this game by at least 1.5
Let us review which areas of the game are still under contention.
It's obvious that Black has to retreat.
White has a free chance to push through here.
6th LG Cup, semi-final match Lee Chang Ho 9d (Black) vs. Cho Hun Hyun 9d (White)
There are some who after the descent here, will cut, and when Black connects, White can play here.
With this one move, White has robbed Black's territory in the corner.
So there's a big difference between having this stone on the first line or not.
This sequence here would be worth 8 points.
White has a better alternative here with a cut here.
After that move, the next biggest area in the board is over here.
This is because Black can attach underneath here, this move is quite big.
White kosumi.
After the kosumi, the atari here is worth 10 points.
Why is it worth 10 points?
Because after the atari, there's a hane.
This takes away 5 points from Black, and you have obtained 5 points, for a total of 10 points.
So this sort of move, is White's right.
This area over here, sooner or later, will be played out like this.
After the kosumi, Black will connect, and it's likely that we'll end up with this board position.
White then follows up with this.
Black will seal off this area and get those 8 points.
Black, on the board, will still win by a few points.
This is the situation.
However, these two players, know the opponent like they know themselves.
Lee Chang Ho felt its no longer neccessary to play any further so he resigned.
This has caused some rumors that Lee Chang Ho didn't want to fight any longer, or if he had some other uses for this, but I think this is impossible.
These two would not give each other any quarter on the Go board.
And this is the end of today's commentary. [ Subtitles: Heretix (KGS) ]
