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

We've had 25 lessons so far.

This series consists of 30 episodes.

Since there's not much time left, we need to review what we've learned.

By now, you'll know many 4-4 variations.

This will make learning the 3-4 variations much easier later on.

Today, we'll look at the 3-3 invasion, which you know well.

This lesson will be good revision.

If you don't remember this invasion, you'll need to focus.

Let's begin today's lesson!

We'll start with our basic fuseki.

You already know many 3-3 invasion variations.

However, there are also more complicated ones.

Therefore, you still need to learn more about the 3-3 point.

If black pincers, white will take sente and approach again.

To build a big moyo, black needs to play on the fourth line.

This double wing formation is one of the best positions in the fuseki.

What comes to mind first when you see the double wing formation?

Many would consider the 3-3 invasion.

Therefore, we need to learn about the invasion.

Since the right hand side is worth more, black has to block this way.

It's one of the most common and easiest josekis we've learned about.

You can either hane or play here.

Let's compare the two moves.

After pushing, white hanes here.

This joseki is often played by beginners.

This is a basic joseki.

Let's try another one.

When white hanes, black has other options.

Black can double hane, or play here.

You need to choose the appropriate move depending on the context.

Let's look at the double hane first.

Capturing black's stone is the easiest option for white.

It's an exchange.

Some players make a mistake here.

They cut and capture these two stones, thinking that the corner is big.

In many cases, this strategy is good.

However, that's not the case with this double wing formation.

After white pushes here, the formation will be broken.

If black hanes here, it'll only isolate the stone on the left.

This double hane doesn't work because there's aji in the corner.

If white moves out like this, black will be in trouble.

If black tries to capture these stones, white will cut here.

When white pushes, black can't block.

Black will die.

So this extension is unavoidable, but white will push too.

Now this stone becomes a target for attack.

It's no good.

In this case, black needs another move.

So, when you have outside influence, this atari is the proper move.

If white connects, then you can capture the corner. It's very different to the previous variation.

White will capture this stone, now this atari is sente.

You can continue here, but it's not so urgent now.

Even if white ataris, you can connect and everything is fine.

Black creates a large framework in both josekis. So what's the difference?

At the top, black took sente, whereas he ended in gote at the bottom.

White haned and took sente but black has a very solid position.

Even though black gains sente at top, it's a bit thinner.

The matter of sente is important in the fuseki.

I think most intermediate players would understand both variations.

Let's investigate another variation.

When black double hanes, white has another option.

Capturing black's single stone isn't the only move.

This hane is the another option.

When black blocks, this crosscut is the key move.

It's a tesuji.

Black mustn't capture this stone. There's a critical cutting point here. It's double atari.

So, in this case, connecting here and this atari are both possible.

This move is more common.

It's a trade.

Because white's group is unsettled, defending is necessary.

Previously, black built a big moyo at the top.

In this case, white successfully ruined black's plan.

Therefore, white's hane is a plausible way of resisting.

It's a good option if you don't want black to have a large moyo.

Let's change the position.

We're going to look at some similar positions and see how black should play.

White hanes here.

At this point, this cut is a good move.

When black connected here, his moyo was erased.

In this case, this atari is possible.

If white moves it out, black will capture white's stone.

So white has to connect instead.

Here's the question.

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

The corner is big and black didn't get enough compensation.

The ponnuki isn't good enough.

When you atari here, you need to consider your stones along the side.

That's because of this move.

If it were on the third line, then the atari would be a good move.

But in this case, it's an overplay.

Let's see the difference.

After black defends, white has to move out.

Can black push like this?

To win the capturing race, black has to extend his liberties by pushing.

This extension is necessary.

After that, if black cuts here, he can capture the corner.

But what about black's original moyo?

It's completely destroyed.

Despite the fact that black captured the corner, it's a disaster.

Black's strategy is inconsistent.

However, if this stone is on the third line, it's a different story.

In that case, black should play like this.

Even though white extends several times, he can't go any further.

White's four stones are in danger and so is the corner.

If white rescues the corner, black will jump and attack white severely.

It's very successful for black.

So keep the position of your stones along the edge in mind.

We've gone through several variations.

There's another possible move, instead of the hane, at the beginning.

Strong players tend to choose this move.

They often play like this.

I'll show you the difference between the two moves.

White can bump, or attach here.

This attachment is more common though.

Black can't block like this.

White will bump, and black doesn't have a proper response.

So black has to extend. Then white hanes here.

Black has to defend his cutting point.

It's similar to the basic joseki.

Black's supposed to take gote anyway.

What's the difference then?

At the top, this move doesn't affect the corner at all.

At the bottom, this move is big, although it's not sente.

However, capturing this stone will be sente.

So these two variations are quite different.

If white connects here, black encloses the side in sente.

The main difference is that blocking there is very big later.

This push isn't sente.

But since it's still very big, either side might play there in the middle game.

Because of this aji, many strong players prefer the knight's move.

So we've just learned about variations of the 3-3 invasion.

Let's move on to life and death problems.

Today's theme is practicality.

We'll look at the invasion inside black's position again.

This attachment is one of black's options.

When white bumps, black extends.

In response, white needs to push and create weak points in black's shape.

Last time, we looked at the counter-atari.

But how will you answer if black just connects here?

If white pushes through, black can cut immediately.

If white connects, black can block and gets a solid moyo.

Therefore, white has to make a tiger's mouth.

When black ataris, don't just connect here.

After black blocks, white's group will be in danger.

Unlike in the variation from our previous lesson, this cut isn't sente now.

Therefore, this group is in trouble.

Since white can't hane on both sides in sente, this group is dead.

So white needs another move when black ataris.

In this case, this extension is a proper move.

Capturing this stone is sente.

Even though black blocks here, white has more space than before.

This hane is sente now.

There's a cutting point here, so black has to defend.

After that, white can live on the side.

But here's the trade-off. Living on the inside gives the opponent influence.

So before you invade, you need think about this.

If we only look at life and death, we can find a way for this group to live.

There's also another option, for those who don't want to live on the inside.

Up to here, it's the same sequence.

If white plays a tiger's mouth, he can live.

But some players don't like that variation.

What if white pushes through? Of course, black will cut.

White has to sacrifice his stones.

After that, he has to give up more stones.

Then, finally, white can get the corner.

Is the corner secure?

There's some aji in the corner.

Without the aji, the territory would be quite big.

But, this hane is annoying.

If white cuts, this atari is sente.

If white connects, black can atari once more.

So this extension is white's resistance.

At this point, black has a wonderful tesuji.

This is an excellent move!

If white answers like this, this attachment is a great combination!

It's a good strategy to sacrifice.

This atari is sente too, so black can reduce the top side very easily.

If white tries to capture the whole group, black extends here.

White has to defend the cutting point, then black blocks.

White can't capture the corner.

This push and hane is the best white can do.

Locally, the corner can't survive.

Since this move at 1-2 is a tesuji, black's group is supposed to die in normal situations.

But white has a critical weakness in this case.

White has to extend, but black will push again.

When white blocks, black will cut here.

After that, one of white's groups will die.

So white can't capture the corner.

Therefore, it turns out that trying to kill black is an overplay.

In conclusion, the variation on the right is the best result for both sides.

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

Thank you!
