Becoming 5 Kyu, Lesson 7.

Welcome back to 'Becoming 5 Kyu', I'm Shim Wooseop.

In previous lessons, we looked at a specific, basic opening and its variations.

Today we're going to study a new basic opening.

Studying basic openings is very useful.

You'll be able to use them in many of your games.

Now I'm going to show you a new basic opening.

Again, we start with a star point formation.

Many weaker players prefer playing on the star points in the opening.

This approach is same as in the previous lessons.

Previously, white enclosed the corner and black extended.

Today we'll study the pincer.

To easiest and simplest way to respond is to play at 3-3.

This joseki is very popular and easy to play.

I'm sure everyone has seen this variation up to here.

Now, let's focus on the next move for white.

Many players approach here, to try to build the lower side.

But there's a flaw in that plan.

After the exchange in the corner, white should play on the 4th line.

If white followed joseki, white would play on the 3rd line.

But then black can press white down like this.

And white can't use the influence on on the left side effectively.

This is why white should play on the 4th line in this situation.

Ideally, white would like to convert the entire lower side into territory.

But this shape has a weakness.

Black can invade here later.

It looks plausible but there are still some weaknesses.

So this isn't a good way to use white's thickness on the left side.

Let's go back and see what happens if white approaches from the other side.

Black should be wary of white's influence and just enclose the corner like this.

Now both players follow a basic joseki.

We've now played out two basic josekis.

We don't need to play on the lower side anymore for now.

Black needs to turn his attention to the top, which has the most potential.

White plays on the 3rd line because of black's shape in the bottom left.

Again, both sides follow a basic joseki here.

So far, it's all fairly simple.

Now white needs to decide where to play.

The only corner that hasn't been played in is the top right.

As you can see, both the top and left side are the same.

So white doesn't need to play at the top inside black's influence and ask for trouble.

Approaching from this side is much better.

Black plays on the 4th line to create balance with his 3rd line stones in the top left.

White has many options here now, such as jumping into 3-3 or sliding with the knight's move.

But no matter which way white plays,

after white defends the right side,

black will get to come back and play on the bottom side first.

Black also can play a smaller extension.

If black approaches here, black's single stone here still has some potential later.

It's a dilemma for white. White doesn't want to reinforce but he needs to.

So white doesn't approach the top right first because it's gote.

White should extend on the lower side before black gets there.

And white can aim to attack the bottom right later.

Black shouldn't play at the bottom, but in the unoccupied corner now.

Black encloses like this and he's also satisfied.

This is the basic opening form form today, which we'll use to study some variations.

We'll focus on black's position at the top.

We're going to study invading and attacking in this position.

The black stones at the top are well placed to work together.

So where should white invade?

If white just follows joseki, without accounting for the surrounding stones,

white can come under attack from both sides.

White is completely outnumbered here, 3 against 1.

There's a special way to play in your opponent's area of influence.

I'll show you some options for playing here.

This attachment is one idea.

White can also play here.

This looks strange but white can also consider playing here.

These three different moves are the most popular approaches in this sort of situation.

First, I'll show you the easiest option.

This move has been popular recently and leads to easy variations.

If you watch a lot of games, you might have already seen it.

But you also need to understand each followup move.

When white plays like this, what do you think the best response for black is?

Playing 3-3 isn't good enough in this case.

This might look odd but it's a really good response.

Depending on white's subsequent play, black can block on either side.

It's better for white to extend to the left and for black to block the corner.

Then white plays the large knight's move.

And white gets settled.

Of course, black can invade like this later.

But it depends on the situation.

Anyway white successfully reduced black's area.

And white's shape is quite light.

Now black can consider playing somewhere else.

But there's still some bad aji in the corner.

The left side is big but this extension is more valuable to black.

So what about the bad aji in the corner?

This attachment is a good tesuji and black's in a spot of bother.

It would be too upsetting for black if white connected on the 1st line.

If black blocks now, white can extend from down here to attack.

Black can think about descending to keep white separated.

Actually white can't cut right away, because it's a ladder.

But there's a good tesuji for white in this shape.

It looks a bit strange - white attaches here.

Try to remember this unusual move and use it in actual games.

So, what's the meaning of this?

Let's examine the variations if black hanes on this side.

White can just counter hane.

You see, black can't block directly, because there are cutting points.

And capturing a stone doesn't work for black either.

The 2 black stones in the corner would be captured.

So white will eventually take the corner and settle down.

White's tesuji works very well.

Next, what if black just extends like this?

White is needs to think about life and death inside black's shape.

But actually, white doesn't need to think too much.

Now white just cuts straight away.

It's similar to before but now there's no ladder.

After white connects, capturing the corner and coming out are miai.

It's out of question to concede the corner to white.

White's tesuji makes it difficult for black to play.

Now that you've seen these variations,

you can see that black needs to extend on the right as soon as possible.

Now black would be ok even if white attaches like this.

Black just lets white connect and block. There's no problem anymore.

Therefore, extending is essential in this formation.

In other words, black needs to extend to indirectly reinforce the corner.

Black has another option too.

Let's think about if black wants to build big moyo at the top.

In that case, a pincer would work well.

You may worry that white will split black.

But compare it to if black just defended the corner immediately.

White would have been able to extend as far as here.

But now it looks like white just kosumied and black played on the vital point.

So in this case, white has to play at 3-3.

Black blocks.

And white still can't play here.

The two cutting points are miai.

So white just reinforces the corner like this.

Now white can run out if black descends on the right side.

So black seals off the top and white plays to live.

The result is that white takes the corner and black builds influence.

When you choose this variation, you need to consider the situation at the top.

Usually, white doesn't play to live right away.

If black tries to kill the corner, white can make a ko.

Even if white loses the ko, white can play twice somewhere else.

So now we have studied some invasions and their followups.

There were two ways for black to respond.

Protect the corner or build a moyo at the top.

I hope you will find these useful in your own games.

Now let's move on to life and death.

We'll continue to study the same shape from previous lessons.

As you know by now, splitting black is the best way to reduce black's moyo in this position.

Then black approaches and white extends two spaces.

Black attaches here to make white over concentrated.

And black encloses the corner with a knight's move.

We have studied life and death in this situation.

Today, we will examine the strongest move for black.

3-3 is always a conflicting point for both.

In our previous lesson, we studied this descent.

We also looked at this empty triangle to try to kill the corner.

But ultimately, black couldn't kill white's corner stone.

So now black needs to think about how to best attack the lower white group.

Today we're going to study this move.

This move seems more threatening to white's corner stone.

White might feel momentarily panicked!

Now, white's answer is very important.

Most importantly, white has to block the corner to keep potential for eye shape.

White doesn't need to consider other moves.

However, what if black blocks right away on top?

What can white do?

Look carefully. Black also has weak point here.

So, what if white plays an asking move?

But if black connects below, white will be in trouble.

White has to cut and start a capturing race.

Do you know this shape? There's a really famous tesuji here.

Black attaches here and wins the capturing race.

Even though white extends, black just fill white's liberties.

Now black has 3 liberties while white has only has 2.

White can't get more liberties.

So black captures white with this attachment.

Therefore, white can't cut right away.

What do you think white should do here?

There's a proverb, "the opponent's vital point is your own."

So white should play where black attached earlier.

Now if black descends, white can try to cut.

It's not quite the same as before, because now white wins the capturing race.

Black has 3 liberties and white has 4. Black will die.

So black has to reinforce here.

The hane is better than a solid connection here.

And white plays to live like this.

In conclusion, black can't kill the corner by blocking.

But black can weaken white's group on the lower side.

Black can get some profit by attacking white.

So - I want to stress this again - remember that black can't kill the corner.

White has this empty triangle in mind to live against black's block.

So black needs to plan the best way to attack white at the bottom, after white lives.

We'll look at this in our next lesson.

We'll also study some other moves in this situation down here.

This brings us to the end of Lesson 7.

I look forward to seeing you next time.

Thank you.
