Episode 26: Life and Death I

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

Starting today, we're going to explore life and death!

Along with learning tesuji, life and death is the best way to improve your reading skills.

We'll focus on practicality throughout the series.

And you'll also get to experience some high level problems.

Let's begin today's lesson!

Some of you may have solved the proverb related problems in 'Level Up to 7 Kyu'.

I imagine that you learned some useful skills at the time.

However, I recommend that you now free your mind from what you learned.

In other words, you need to learn to apply your skills in a more versatile manner.

Then you'll be able to read more than you used to.

Let's look at this problem first.

White has to escape from the prison created by black.

This problem is from the Xuanxuan Qijing, a classical tsumego collection.

How can white escape?

Let me show you the answer.

First of all, white has to push. Black can't block here.

If white pushes, black can't stop white because of his weaknesses.

So this extension is the proper move.

Next, let's make an empty triangle like this.

As we saw earlier, this move lets white escape.

So black has to extend here again.

After that, white needs to push at either of these points.

Subsequently, white cuts here. This is the answer.

This push is fine, since the position is symmetrical.

First, black has a weakness here.

So he needs to connect.

Then white ataris and pushes.

If black blocks, white can cut here.

With this atari, white can successfully escape.

When white cuts, black has to defend his weakness.

After that, white can rescue her group with continuous ataris.

Is this kind of answer familiar to you?

Probably not, so you need to think flexibly.

Let's move on to this one.

It's white's turn. What's the best way to capture the corner?

Can you see the answer?

I've tested some players with this problem in the past.

Some of them tried this move.

And other people played here.

What's the best answer?

The best way to capture these four stones is to tenuki!

You don't need to play in the corner. This group is already dead.

It can't be rescued.

Black can't live.

Even if black hanes, it's still dead.

If you know this, you won't waste a move capturing this dead group.

We're going to look at some practical problems.

In addition, we'll investigate how the examples could arise.

Let's explore some practical life and death problems together!

What's the definition of a practical life and death problem?

As the term implies, the shape often appears in actual games.

It's useful for us to solve as many problems as possible.

However, practical situations are more helpful.

Even if you solve hard problems, it will be useless if you can't utilize them.

Let's see look at this problem.

We may face this kind of situation in our games.

After white's approach, black attached and played a knight's move.

This attachment is played by pros.

Do you know when they play like that?

When white can play here? No, it's the other way around.

In most cases, there would already be a black stone around here.

After white extends, black will jump.

In handicap games, I aim at the 3-3 invasion very often.

Or, after playing here, these invasions can be other aims.

Anyway, white can invade black's corner later.

If you don't know the proper answers, you'll lose many points in the corner.

This move is the safest, but you'll lose a few points.

Depending on the situation, it's a possible response though.

Do you remember learning about this shape?

Here's the vital point.

Therefore, white doesn't make this exchange yet and tenukis.

Isn't it too passive? How about separating white like this?

Yes, we can!

After that, white needs to rescue her group.

If it can't survive, white will lose many points.

Let's save this group.

First, white needs to widen her eye space.

If black blocks here, it'll be hopeless.

In response to this block, exchange this push.

Now here's a problem.

How can white live in the corner?

I advise you to think laterally.

Where would black play to capture this group?

After this exchange, here's the vital point.

The enemy's vital point is your own - so this move is the answer.

Locally, this group can't live.

Because of this placement, white can't make two eyes.

Is it dead then?

We need to think on a larger scale.

If black insists on capturing the corner, white has a good counter.

This cut works now.

If white cuts here, black can't manage both sides.

Because of that, white's kosumi is a nice move.

When white plays here, black has to defend his cutting point.

If black exchanges this first, white can descend here.

So both sides reach a compromise.

In response to the 3-3 invasion, black can descend here.

This move intends to apply some pressure to this white group.

After white's kosumi, black should defend with a knight's move.

Here's another example.

Suppose you defend here at some point.

Do you think white can still invade the corner?

No, it doesn't work now.

Black can capture this stone by descending here.

Black no longer has any weaknesses.

Don't forget this.

Let's investigate black's possible answers.

In response to the 3-3 invasion, black has several choices.

These two moves aren't everything.

Black can separate white with an empty triangle.

In doing so, you can aim at this white group.

Otherwise, you should block here instead.

Let's examine this move now.

Do you think white can survive in the corner?

This push is possible.

After this bump, white hanes, then plays a tiger's mouth.

It's a ko.

In response to black's atari, white starts the ko.

This sort of tiger's mouth usually aims to make a ko.

When rescuing your group, the tiger's mouth is generally good.

There's another option too.

This kosumi is also fine.

This attachment is the strongest response for black.

Here's your second puzzle. How would you save the corner?

Will it survive, die, or just make ko?

In this case, 2-2 is the answer.

So this group is alive now.

If black descends, white makes an eye.

She's got two eyes.

How about this placement? It looks like a vital point.

White will play a tiger's mouth here. Capturing black's stones will lead to ko. It's no good.

In this situation, descending here is good.

If black connects here, white can live.

Black's empty triangle is played occasionally.

In response, white can make a ko with the push and tiger's mouth.

And the second choice is to kosumi and live in the corner.

Isn't the second option better then?

Well, in response to the kosumi, black will wedge here instead.

This group can survive anyway.

White can easily make two eyes.

If you're satisfied with this, it's ok.

But if you'd like to aim at black's weakness here, I recommend the push.

Or, you can peep here as well.

In that case, making a ko is still a good choice.

In summary, white has two options.

In response to the kosumi, black has to wedge and block here.

Remember both variations! Let's move on to our next pattern.

We're learning about practical life and death problems.

Let's try this kosumi.

As with other variations, black intends to separate white.

After this move, black can exchange this tiger's mouth in sente.

So black can attack white.

How would you manage your stone in the corner?

First of all, you need to block here.

If black pushes first, this group will simply die.

After this move, you can aim at this weakness.

Because of that, black must play here.

If white answers here immediately, black will block.

Do you remember the shape I showed you at the beginning?

As you saw, this group is dead.

Remember this shape. White can't rescue it.

So it isn't a good idea for white.

Before blocking here, white needs to exchange some other moves.

This knight's move is good. Black has to block.

After that, you can block here.

Capturing this stone is tempting.

White has no hope of making two eyes on the inside.

However, this weak point is exposed!

If white cuts black, these stones will die.

It isn't good.

In other words, this point is sente.

Inevitably, black has to defend his weakness like this.

In response, this hane is a great move!

It aims to atari and cut.

Exchanging this isn't too bad.

But omitting the exchange shows a more sophisticated technique.

Black has to connect, then this pinch is a nice move.

In this case, white can exchange these moves. It's fine.

Black has no choice but to connect.

Now let's try this tiger's mouth. Do you think this group is alive?

You need to become familiar with these sorts of life and death shapes.

To state the conclusion first, white's alive.

This stone plays an important role in this group's life.

This throw in is a good move though.

If white captures, black will play at 1-2.

Even if white can make this exchange in sente, she can't avoid a ko.

White has to capture this stone to make one eye.

But she can't completely rescue the corner. It's a ko.

If white connects here, the entire group will die.

Thanks to this exchange, white can make a ko.

However, white shouldn't capture this stone now.

Instead, this move is the best answer.

Black can't capture the corner.

He can't remove any of white's eyes.

So white can rescue the corner with this extension.

What if black descends here first?

Can white capture this stone now?

Be careful not to do so. Black will play at 2-2 and kill white's group.

Instead, white needs to secure one eye.

Here's her first eye.

Black can't play here, so he has to capture this stone.

In the end, the corner can't be captured.

Sometimes you might face this kind of position.

If white has a stone here, she can survive.

Otherwise, black can hane and attack this group.

White can't fall back like this now.

In response to this blocking move, this placement is good.

If white can hane here in sente, the result will be a ko.

Otherwise, the corner is dead.

If white connects here, black descends and captures the group.

You should become familiar with these shapes.

After this knight's move, the hane is a good exchange.

And after this tiger's mouth, the corner is safe.

Today we've learned about black's attack after separating white in the corner.

If black doesn't have any influence nearby, white can survive in the corner.

However, you should review the moves we looked at today, so you can rescue or capture the corner.

1 Minute Summary
