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

I like the Korean proverb: "To help others is to help yourself."

In Go, when you take profit, your opponent loses points.

In contrast, when your opponent is successful, it won't be good for you.

However, the proverb teaches us how to live together.

Even though it's still hard to put into practice.

Go gives us lots of pleasure regardless of the result.

This game has a positive impact on players, like the proverb I mentioned.

Let's begin today's lesson.

Today, we'll look at a new fuseki.

The josekis involved are practical and are often played.

Last time, we examined this double approach.

This jump is favored by those who like building a big moyo.

It's often played by those sorts of players.

By pressing white's stone, black can gain considerable influence on the outside.

One precondition is that the ladder has to favor black.

Please remember this.

When there's a ladder breaker here, pressing like this is a bit dangerous.

In this case, white will push and cut.

It's very powerful when the ladder favors white.

Black can't extend here.

This extension isn't a good idea either.

After white breaks through, black's in trouble.

The white stone in the bottom right is still a ladder breaker.

As a result, black's separated.

This is the best way for black to resist.

White can easily escape with this atari.

The ladder still isn't favorable for black.

That's a problem.

Even though black can rescue this stone, white's corner is very big.

In response to black's jump, white can move his stone out.

So remember to check the ladder before playing this joseki.

When you're white here, the first thing you should consider is the push and cut.

However, the ladder favors black at the moment, so it doesn't work now.

What if white pushes and cuts anyway? You need to know the punishment.

If you still block, white will escape and take many points in the corner.

Don't forget to atari here.

It looks a bit strange, but it's the only response.

If white ataris, black will capture. It's a disaster.

So white must come out, and then push here.

If white plays here, to avoid the ladder, his two stones will die.

Therefore, he'll try to capture black like this.

White has to atari once more.

Now white has to block here, to save these two stones.

Black only has two liberties, and the ladder doesn't work right now.

So he needs to push first.

When white blocks here, it's time to think very carefully.

Black doesn't have time to extend here.

He has only two liberties.

Therefore, black has to sacrifice his stone like this.

Thanks to this exchange, black can always atari here in sente.

White has to come out, then it's a ladder.

But it's better style if black doesn't atari immediately.

This atari is even better.

If white comes out, then black can atari here.

Black's supposed to capture these stones with a turtle's back shape.

Undoubtedly, black's very successful.

So white can only push and cut if the ladder's favorable.

Therefore, white can't resist in this situation.

Because the ladder is unfavorable.

Instead of the cut, white has to push.

After two pushes, white jumps here.

In the past, black used to connect, or play a tiger's mouth like this.

But if white splits black, like this, the influence isn't very effective.

As many players know, black plays a knight's move now.

This is the key move in this joseki.

We'll look at some variations that can occur after the joseki.

It's easy for white to misjudge the situation.

Many players would be tempted to cut black like this.

Many cutting points are exposed.

If black connects here, white will cut, and the whole group will be in danger.

Some players would be satisfied with capturing this stone.

But it's penny wise and pound foolish.

Black will take this big point and exploit his large moyo.

A moyo made by both sides is incomparable.

Furthermore, the corner isn't completely secure.

We'll talk about that later.

Anyway, that means it's time to reduce black's influence.

Splitting here is normal.

Since black's moyo is bound to be erased, he needs to attack white's group instead now.

Black can't miss both points.

To start with, he needs to defend here.

Then white must jump, to look after his group.

Even without this move, the group is safe.

But once black plays here, defending becomes urgent.

Some people want to play here, but black will attack the top group very severely.

This is a vital point.

White has to beg for his life, making several bad exchanges.

Because of black's aim here, white has to defend.

But due to the bad exchanges, black can invade at 3-3 more easily.

The corner will be destroyed quite easily. It's very bad.

So remember to jump when black connects here.

Up to here, white's managed his groups very well, while black hasn't gained any profit.

So he has to get compensation by attacking the corner.

This approach move is the vital point of white's position.

White can't let black enclose like this.

He must come out.

After that, this knight's move is common.

This extension isn't good in this case.

After a forcing exchange, white will jump out, erasing black's influence.

This black group becomes something of a target.

If black tenukis, white will peep and jump.

It's no longer influence at all.

However, there's no proper defense.

To prevent it, black plays a knight's move like this.

This attachment is a typical mistake, made by many players.

It's a very bad exchange.

After black extends, many weak points are exposed.

It's no good.

Attach this way instead.

If black extends, white can block here in sente.

Black has to defend his weakness and prevent white's hane.

After that, it's time to secure the corner.

White can make many points in the corner.

In exchange, black can develop the left side.

Even though black's influence was reduced, he was also able to settle down inside white's area.

It's sufficient compensation.

On the other hand, white managed his groups quite easily.

If you don't like it, you may choose another variation.

We'll look at that in the next lesson.

Let's move on to life and death problems.

Today's theme is practicality.

This is a familiar variation after a joseki.

We looked at whether or not white can survive in black's moyo.

Last time, we investigated this kosumi and it turned out that black can't capture white.

Let's examine this attachment today.

We learned about this bump earlier.

This move is also conceivable.

If black connects, white will bump and he'll have more eye space.

So black should extend here.

Can white survive?

I've said before that you need to look for forcing moves when living on the inside.

In this case, this jump fits the bill.

Black has several choices. Let's try this first.

White can kosumi here in sente.

Black has to block, then white can kosumi again.

After that, white can live simply.

What if black tries to attach like this?

Black has to block here anyway, due to the weakness.

It's alive too.

It's too simple. Black needs to find another way to attack.

Some may question why black has to block here.

Following the proverb, 'the enemy's vital point is your own,' how about this kosumi?

Regardless of the result, you should always keep that proverb in mind.

White can't peep here because her stones are too thin.

Therefore, she needs to push.

Then white can push again.

When black hanes, how would you save this group?

Despite the wide eye space, white has to be very careful.

Instead of enlarging the space, white has to play here.

This move will always be sente.

However, there's no need to exchange it immediately.

This group is safe, with miai.

Other moves seem to be possible too.

But this leaves a vital point exposed.

If black plays here, white has to connect.

I taught you about the basic theory of life and death earlier.

In this case, white can't make a tiger's mouth shape.

So you have to reduce the eye space.

Therefore, this hane is the answer.

If white blocks, this is the most crucial point.

This looks like the vital point.

But that's an oversight.

In response, white will kosumi here.

Black has to play inside white's moyo to capture.

If black plays here, white will pinch.

It's seki.

Even though black might peep here, this move is sente.

It's seki too.

In this case too, black needs to think of where white will play.

Black failed because of white's kosumi.

So he has to kosumi first.

If white blocks, black kosumis again.

White will die after black makes a bulky five.

[Ed: Even if white forces at 3-4, black removes outside liberties, then makes an eye inside. White dies.]

Even though white captures black's stones, he can't live.

White can't play here either.

There's only one eye.

Therefore, white mustn't block like this.

So this tiger's mouth is the right move.

In general, an invasion allows the opponent to gain outside influence.

However, we're focusing on life and death here.

These skills will surely be useful to you in an emergency.

Thank you!
