Episode 30 - Life and Death V

Hello everyone, welcome back to 'Level Up to 3 Kyu'. I'm Lee Jihyun 3p.

This is the final episode of 'Level Up to 3 Kyu'.

Let's begin today's lesson!

Our final lesson lesson on practical life and death will focus on the large knight's move!

The large knight's move focuses on speed.

However, it's thinner than the small knight's move and the one space jump.

We'll investigate that thinness today.

Look at this position. In response to white's approach, black made an iron pillar.

By the way, approaching here is more or less sente in this case.

Black should defend his moyo like this.

What if black tenukis?

The vital point of this position is in the middle, here.

How about blocking like this?

White can easily connect under.

This can be regarded as a success for white.

Let's try this move then.

However, later, white can move her stone out like this.

And above all, this exchange in itself is profitable for white.

White can hane and play a tiger's mouth later.

She's got a lot of options.

So blocking here isn't good.

If black wants to attack white, this extension is the only move.

In response, white will push and hane.

Connecting here is sente.

After that, white slides here.

Black has a critical weakness here. If white cuts, it's hard to manage black's groups.

So connecting here is inevitable, then white can live in the corner.

Here's the first question.

If white tenukis now, how can black punish her?

Is this group supposed to die, or can it survive with a ko?

This kosumi is the answer.

White can't rescue her group.

If white plays here, black strikes at the vital point.

After that, white can't make two eyes in the corner.

This push is sente though.

If white tries to save the group, black reduces white's eyespace like this.

If white keeps expanding her eye space, this placement is the finishing blow!

This move move order doesn't change anything. Black will still hane.

This group can't survive.

Even though it looks loose, this kosumi is a wonderful move.

Therefore, defending here is essential.

However, some players are afraid to cut here.

So, many of them are worried about black's counter-attack.

Well, the battle may be complicated.

In addition, you might worry that nearby stones will affect the fighting.

In that case, there's a good tesuji for you.

In response to this extension, we saw white push and hane.

But playing this move before making those exchanges is brilliant.

Remember this!

If black blocks here, now it's time to push and hane.

Black has no choice but to connect.

After that, just extend here.

It's practically the same as this kosumi.

With this move, white's completely alive, while black has yet to defend his cutting point.

Thanks to this exchange, white lived in sente.

Therefore, black should choose another move.

This jump is a better response.

Then white connects.

Can you see this empty triangle? It's a tesuji.

To prevent that, black must spend one move here.

You should remember both of white's options.

And you should also remember that if white tenukis, black can capture him with the kosumi.

Anyway, white can invade and reduce black's territory.

Because of that, black should jump here.

He wouldn't need to do so if the position were one point narrower.

But since this position is more vulnerable to invasion, black should defend.

In this way, black can develop a solid position.

Remember this vital point and let's move on to our next shape.

This is our second example.

Black enclosed the corner with a kosumi.

Once white approaches, she can aim to invade here.

In this position, white can invade at 3-3 at any time.

And white can reduce black's territory in this case too.

What if black pushes from the outside?

Unlike the previous variation, white can't aim at this cutting point.

However, white has an advantage.

If she jumps, she can live in the corner.

And, at the very least, white can make a ko.

Black's corner is destroyed in this case, so it's unacceptable.

Therefore, black should block here, protecting his corner.

By playing there, black can minimize the damage.

If white has supporting stones nearby, she can move this stone out like this.

After exchanging this hane, white can bump here.

Then this jump completes a good combination.

What if black pushes and cuts immediately?

In this case, this hane works.

So black can't capture white.

This works better when you have some stones nearby.

If not, you can exchange this move and wait for the right time to continue here.

Instead of cutting, black should attach like this.

If black can't attack white's group effectively, this aji is very strong.

What if black shuts white in like this?

How would you respond?

As we've learned many times, 3-3 is the vital point.

Black can never capture this group.

Let's try some moves.

It's worth noting that this kosumi is sente.

And white can play many other forcing moves too.

Even this attachment is sente.

Black might try to reduce white's eye space like this.

In response, this attachment is a good move.

If black hanes, white cuts here immediately.

Black can capture this stone, but white will break through into the center.

If black falls back, white can easily manage her group.

She's made many points in the corner.

Let's look at this position again.

After this approach, white can invade here anytime.

For black, blocking here is the best move.

This way, he can see how white responds and answer accordingly.

This is the best result for both sides.

Those are the essential things you need to know about the large knight's move formation.

Don't forget that the large knight's move is thinner than the knight's move and one space jump!

Therefore, black should defend after white's approach.

The last thing we're going to investigate is a life and death problem which appears after a joseki.

I made this up a little to create a problem.

Do you know how this shape is formed?

This is based on a 4-4 joseki.

White double approached.

It means that black's tenukied once already.

In response, black should attach here.

Then, after blocking here, this is the joseki.

Each move has its own purpose.

And I added these white stones.

So this problem is derived from this joseki.

Black should defend the corner with this hane.

But if he tenukis, how can white capture black?

I hope you'll find the answer!

To kill this group, you need to find the vital point.

Reducing black's eye space isn't a good choice in this case.

This attachment hits the vital point.

How should black respond?

If he descends here, this move is sente.

This connection is necessary, then white can connect under.

So black dies instantly.

Black must try another move.

This counter-attachment is nice.

It seems like black's situation is hopeless after white's atari.

However, with this move, black can make a ko.

If white connects here, black will live.

After this atari, he can hane.

In other words, black only needs to win the ko once to rescue his group.

So is a ko the answer?

No, it isn't. White can capture this group unconditionally.

How can white kill the group?

In this case, this placement is a wonderful move.

Let me show you why it's good.

If black answers here, white can connect under.

After that, black can't make two eyes.

Then how about separating white like this?

However, this hane is another good move.

Black has to block, but this cut continues a nice combination.

After black captures, white ataris again.

Because of this double atari, black has to connect here.

After this throw in, white ataris.

Black can capture these three stones.

Even if black enlarges his eye space, he can't survive.

White can tenuki, because this group is already dead.

Eventually black has to capture white's stones.

Afterwards, white's placement will kill black.

How about inducing a ko by connecting here?

Will it be a ko?

No, white doesn't have to do that.

After that, white can still capture black.

It's not much different to the previous variation.

Let's review this problem again.

Instead of this attachment, this placement is a better way to attack.

It's hard to see, but this is a vital point.

So black can't save his group.

Therefore, black has to defend his corner.

That's why this hane is the last move of the joseki.

Do you understand why black has to play there now?

1 Minute Summary

Today we learned about the large knight's move with a focus on life and death.

I expect that you'll now understand why the large knight's move is considered to be thin.

And you'll also know how to invade and take advantage of that thinness.

In addition, you should know why black has to defend his corner at the end of the joseki we just looked at.

So you'll be able to punish your opponent properly if they tenuki.

This brings us to the end of 'Level Up to 3 Kyu'.

I hope you've learned many useful skills from these lessons!

We've studied fuseki, joseki, tesuji, and life and death problems together.

They're similar in nature, so the best approach is to study them simultaneously.

So, in the future, don't forget to study all of them at once!

Sadly, it's time to say goodbye to you now.

I hope that these lessons have helped you to become stronger!

Thank you and goodbye!
