Hello everyone, welcome back to 'Becoming 5 Kyu'. I'm Shim Wooseop 7d.

Whenever you improve your Go skills, you'll also gain confidence.

Some Korean Go players like to bet on games.

Some even refuse to play without placing a bet first.

There are three types of dumb players in betting games.

Let me tell you about those who can't become stronger.

Firstly, those that never admit they're weak, even if they lose a lot.

So they become good targets for stronger players!

Secondly, weak players who get upset easily during games.

They are the best opponents for those who look for victims.

Finally, those that rush to raise the stakes.

They are generally greedy and rash.

You, of course, like all my students, wouldn't fall into any of those categories!

Let's begin today's lesson.

We'll finish another fuseki today.

We'll look at the basic opening which you should be very familiar with by now.

We've learned about many invasions in this sanrensei position.

You can easily imagine and play out this joseki in your head now.

We've reviewed this many times.

This approach is played to prevent black from forming a double wing.

Black kept expanding his moyo with this pincer.

To study the invasion, I start with this jump.

Before your opponent makes a double wing, you need to interrupt the flow.

Here's another joseki.

Up to here, white has a framework on the outside.

Today, we'll learn more about invading on the right side.

We've looked at this already.

We wrapped it up last time, remember?

All you need to remember is the kosumi.

Once you're familiar with this move, you can attack white with confidence.

Before that, we looked at the invasion on the third line.

We've studied this attachment, where black gets outside influence.

Today, we'll review an attacking move.

First of all, black blocks off the top.

The diagonal attachment is bad. This move is better when defending.

After securing this area, you can aim to attack white.

White has to decide whether it's a good idea to escape.

Let's try this jump.

In this case, black has to be wary of white's potential enclosure.

If black tenukis, white will play a knight's move and black will be shut in.

In Go, you mustn't miss such a vital point.

So jump out! Some players worry about this weakness and play like this.

This attachment is also possible in some circumstances.

However, this move doesn't attack either white group effectively.

This jump is the best response. But be prepared for white's peep.

Don't just connect now.

Remember to counter-attack like this!

If white blocks, black will cut and capture white's stone.

If white extends, black pushes through and profits from this exchange.

Therefore, there's no need to worry about this peep.

Don't forget this!

White needs to look after his weak group somehow.

For black, this answer is good enough.

White manages to escape.

Now black needs to come back to this corner.

This attachment is a great move for strengthening black's stones!

White should hane here now. There's even a proverb about this.

This move looks so awkward now. The black stones are inefficient.

In this case, black can play a tiger's mouth.

If white ataris, don't play here. It's an empty triangle.

Instead, you should start a ko, which you don't have to win.

If you're worried about the ko, just extend here.

White finishes the ko, but makes such an ugly shape.

When black attaches, white can't extend. This tiger's mouth is too powerful.

Because of that, white needs to play here.

In response, black can secure the corner easily.

Then white will defend.

If white connects like this, the moyo will become very large.

Therefore, black needs to continue to separate white.

This will lead to profits later on, even if that's not apparent now.

Black has also reduced white's territory and potential.

Even though black allowed white to escape, this is playable.

If white doesn't like this, white will have to think of something else.

Let's investigate whether white can live on the inside.

In this case, this peep is a nice tesuji.

Black must connect.

In this situation, white has two options.

If white chooses this move, black blocks on the other side.

When white plays here, this moyo looks quite good.

At this point, this peep is a well-timed move!

If white tries to capture black's stone, this hane is a good combination.

White can't respond like this because of this cutting point.

But, if he connects, black will shut white in.

Therefore, white has to connect here.

This exchange leaves some aji for later.

However, separating white is more urgent at this stage.

Black's corner is secure, while the white group is unstable.

So this variation favors black.

Therefore, white needs to think about another move.

The next move is played very frequently.

You need to push into the corner.

In response, black splits white.

This hane allows white to connect out on the left.

These moves are all sente.

Can you see a tesuji for white to connect here?

This is the tesuji. It's a knight's move from both sides.

This move isn't good. White will be in trouble if black wedges here.

If white ataris, black will counter-atari and the four stones will die.

After this move, black can't separate white.

Just remember to extend when black descends and you'll have nothing to worry about

With this progression, black will gain both territory and a large moyo.

On the other hand, white took some points in the corner.

The fuseki is nearly finished.

Remember, when white invades, the iron pillar is better than the diagonal attachment.

I hope you've learned a lot about strong positions from this opening.

Let's move on to life and death problems.

Today, we'll focus on practicality.

This black position is often seen in amateur games.

White can invade at 3-3.

We'll examine whether this invasion is possible or not.

So, let's start!

If there's a stone here, white can easily invade here.

However, is it possible without the supporting stone?

Many people would respond with this attachment.

Some people might play this kosumi, to capture the stone.

Let's see which move is better.

Let's look at the attachment first.

White can extend on either side.

Let's try this move first.

This is the simplest sequence.

White needs to push once more.

Then white lives easily.

In exchange, black acquired thickness.

But his right side was destroyed, so it doesn't seem so nice.

Let's try another move.

Some players might want to capture these two stones, to save this area.

So let's consider the double-hane.

White can't connect. Instead, white has to cut and capture black's stone.

When your opponent double-hanes on the 2nd line, capturing is usually good.

So, black captures these two stones.

Since black's stone is here, white can't move them out.

If white tries to, black mustn't block on this side.

Instead, he needs to push here first.

After that, block here. Now black has one more liberty.

Some might think this is better for black.

However, the 3-3 point is still open to invasion.

So black can't expect to keep many points here.

Meanwhile, white's captured black's stone in style. This is better for white.

Well, let's try another move then.

If black attaches, white will extend.

We saw some simple variations.

This extension is a strong move.

Unlike before, white can't come out along the right side.

White needs to think more carefully now.

The first thing to do is exploit your opponent's weaknesses.

Since black didn't protect here, white pushes here first.

Then this atari is necessary.

At this point, black can rescue his stone, or enclose white.

Let's look at this move first.

Of course, white will capture this stone.

This ko is impossible.

This ko is worth too much and there are no ko threats in the opening.

Therefore, white can't cut there.

After that, the hane is the only move.

Black can't block here, because of the double atari.

He needs to capture white's stone to remove his weak point.

Up to here, white only has 4 stones in a row on the side.

In theory, white is supposed to die.

However, if white can hane and connect on both sides, this group can live.

First, cut here to aim at black's weak point.

Some people are tempted to capture this stone.

But even after this cut, black's position looks solid.

Therefore, white shouldn't capture first.

In this case, cutting first is the right move.

Now, if white captures, it's double-atari!

So black has to connect like this and ends up with bad shape.

After that, white can hane and connect here in sente.

Black has to defend this cutting point.

As a result, white can play the hane on both sides.

So this group is alive!

But remember, white allowed black some influence on the outside.

So we should determine the value of black's moyo.

But today's focus was on the white group's ability to live.

And white managed to live inside black's moyo.

There's also another way to live.

The right side variation can be too complicated.

This move is more powerful than the other move.

After that, remember to leave aji by pushing here.

When white ataris, black blocks like this.

If white hanes, it'll end up like the right side did.

If you want something simpler, just connect here.

This move is also possible.

Now this ko isn't as big anymore, so white can cut here.

White has local ko threats, such as this hane.

This ko will remain a burden for black.

White has many ko threats.

This move is recommended when there are many ko threats.

Because of all the cutting points, black should fall back like this.

Since white has one outside liberty, she can slide as far as here.

White can choose between these two variations.

In conclusion, white can live after the invasion.

When you're behind in terms of territory, this will help you to restore the balance of territory.

That brings us to the end of today's lesson.

Thank you!
