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

When I first started studying Go, there weren't many Go books.

So I read almost every book published, and read them over and over again.

And sometimes I used to study extremely high level moves that appear once in a lifetime.

However, those moves weren't useful in actual games, and I've forgotten all of them.

Do you think it was a waste time or was it a good way to learn Go?

It is up to you to judge for yourself.

But I think, at the time, I had a much more passion for learning and my Go skills improved quickly back then.

I hope you can find some passion when watching my lessons.

I always stress that studying the opening is highly applicable to actual games.

So you need to study the opening to learn good strategy.

Remembering some basic patterns can also help.

White can just enclose the corner when black approaches.

When white pincers, black already has a plan.

It's the 3-3 invasion, which is one of the easiest josekis.

Some players spend a lot of time during the opening.

But, even though you might think for a long time, it's really hard to find better moves, because there are too many possibilities.

So I recommend that you just play some good openings that you're familiar with.

Do you remember that I stressed that white shouldn't approach from the left side here?

It seems to build a big moyo, but it's a fragile position.

So you should be able to remember that white should approach here.

And black just encloses, with a low position against white's strong influence over there.

Then they just complete a basic joseki here.

You don't need to think hard about where to play here.

Now there are no weak groups, and now you need to think about where the biggest place is.

The top is the widest place.

White could pincer, but white just encloses here and it's easy.

Black has 2 options here, to play for territory or a big moyo.

But, normally, black doesn't try to build a big moyo here.

There are already white stones on the right that would reduce black's moyo.

So in this situation, black just takes territory, which is more certain.

They played easy josekis on both sides.

Next, the top right is the last big place for both.

However, both sides of the top right are miai.

So white doesn't need to rush to the top right.

Look at the bottom, black and white's positions face each other.

Whoever plays there first will take a big advantage.

Therefore, white should extend here now.

Even though white got to play at the bottom first, black has sente now.

Some weak players get cold feet when white approaches there and reinforce the corner.

It's safe. I understand that feeling, but you'll be letting white take another big point.

In fact, black's safe enough in the bottom right, so black should play in the top right.

Of course, black can play in this direction too.

But the top right corner is still open and the top is still incomplete.

So at this point, black plays 3-dimensionally, creating more potential for the future.

If white doesn't play here now, black can build good moyo with one more move in the corner.

In other words, if black plays like this, white should invade right away to break up the moyo.

This is black's plan, black gets white involved in a fight.

This is the basic sense of playing the opening.

Let me re-emphasize the important thing about this position.

The fight between black and white here is the most important factor in this opening.

Let's continue to look at this invasion and how black can answer it.

As we've already learned, white plays unusual moves when inside black's strong moyo.

If white approaches normally, white will be attacked fiercely by black.

We already seen this move.

And this knight's move.

Today I'm going to introduce this attachment, which may be the last option locally.

Attaching may lead to an immediate fight.

So both black and white should play carefully.

If one makes a mistake, the loss will be very serious.

There's also a kind of joseki for this fight.

It's possible to play joseki by heart, even though we don't really understand.

But if you can learn and understand every sequence in this fight, it will be great!

If that's too hard for you though, you can just remember how to play for now.

Ok, when white attaches, black has 2 options locally. Hane on the inside or the outside.

Firstly, let's examine the hane to protect the corner.

Actually, this hane is more common.

And white normally extends towards the side, rather than descending.

At this point,

Black could connect, extend or push. 3 possible moves are available.

Normally when you're uncertain, connecting is the safe option.

You see, these 3 stones are really strong.

But look at the distance between black's stones.

Normally you want a 2 or 3 space extension. Now it's quite over-concentrated.

So black had better descend in the corner and get territory now.

White can push here in sente, because black didn't connect.

Usually black extends here.

Pushing again wouldn't be sente anymore.

White needs to extend, but can white extend 3 spaces from a 2 stone wall here?

It doesn't work well here, because black would jump in right away.

So, when you're in the opponent's camp, you need to play safely.

This result is easy and satisfactory for both.

Black gets quite a big territory in the corner.

White settles down safely in black's camp. It's the easy way for both.

Now black gets sente and can go to another big place.

I think you can remember this and play this way in actual games.

However, the surrounding position could be different.

So black might connect here, and what can white do next?

Now white can't play here in sente.

Black could respond here, but black doesn't need to, because black's shape's already strong.

Black would play here to attack white and get more territory.

Therefore, white needs to extend here now instead.

This is also easy, right?

Later, black can attack white's group starting with this push.

White might have an aversion towards playing the hane and just extend.

If white just extends, black gets profit in the center in sente, and feels satisfied.

But white would hane with fighting spirit.

Then black might hane here in sente.

White's almost alive and gets some territory here too.

I'm going to show you a useful tip for this sort of shape.

Black's shape is already strong here, so black shouldn't hane.

White makes good shape with the extension.

That is to say, it's a vital point.

This clamp is a good tesuji.

Always keep this sort of idea in mind.

If white just connects, black can block off the center.

Compare this with the shape I showed just before, it's absolutely better for black.

Perhaps white will be angered by the clamp.

What if white resists like this?

Black can cut and capture 2 white stones.

And also, black could aim to attack white's whole group like this.

You see, white doesn't have much eye shape now.

Therefore, when your shape is strong, you can play strongly like this.

We examined some possible moves.

In short, these ways of playing are simple and easy.

The result is ok for both. But you may feel it's a bit too flat to play.

In the next lesson, I'll show you more powerful ways to respond

Now let's move on to life and death.

The 3-3 point is often the focus of life and death problems.

We're going to study this shape today.

It's derived from this formation - when white invades at 3-3 now.

Then white hanes and connects simply.

Black blocks, and white plays a knight's move to settle in the corner.

And black blocks off the side, becoming strong there.

Now white needs to connect and it's the correct move.

But the problem starts after white's tenuki.

Just suppose that black's outside is reinforced.

I also sometimes tenuki here when I play with weaker players, to probe their ability.

And I observe whether they know how to play precisely here or not.

If black fills even one more liberty, it's easy to kill [this is the shape from lesson 9].

In that case, white can't atari against the hane.

However, when this liberty is open, it's much harder to play here.

I'll give you an answer which you should remember.

As I've said previously, when there's no tiger's mouth shape inside, reduce eye space.

In particular, hit 2 stones on the head if you see a chance,

Rather than playing the hane on the other side.

If white just bends, white will die after black hanes here.

So what can white do?

White can atari directly, which is unusual.

First of all, I'll show you the correct move for black after this.

It's neither cutting, nor poking.

It's quite fabulous. The placement is the correct answer.

Sometimes you need to remember this kind of move, because it's hard to find.

Anyway, now white must connect here in order to continue the struggle.

But, after black connects, white can't make an eye here.

The headbutt invites an atari, and white dies.

And the other way doesn't work either.

Now this white group will die after black's hane.

Is this clear to you?

The bent four in the corner is dead, remember?

So, what can white do here? White can create a ko fight.

White can a make a ko like this.

The life and death of white's group is dependent on this ko fight.

As long as white lives, even if it's ko, try to make the eyespace wider.

Just playing atari now lets white live. After white connects, black has no answer.

If black bends, white just hanes.

And if black plays here, white can make a seki.

But black also has a move up his sleeve.

Black throws in and makes ko.

If white just connects now, black can kill this group.

So this fight in the corner leads to ko in the end.

This is the correct answer, I mean, the best way for both.

Now let's review this shape.

We saw that when white blocks, black should make a placement inside.

However, many players tend to poke here. White only can connect.

And then they play inside, where there appears to be a vital point.

It's no wonder anyone thinks like that.

White might play here.

And black needs to remove eye shape.

White's next move is really important.

If white widens her eye space, black hanes in the corner.

It's a ko fight at best.

You can check, it's ko.

Even if white ataris black's 2 stones, black will fill the outside liberty.

You see, white can't play like that, it's a bent four in the corner.

Let's go back to when black removes eye shape.

White can throw in first.

It looks like a ko fight after black hanes.

But white captures here.

Next white can atari here and live.

That is, white throws in first.

Then blocks tightly.

If black connects here, white can fill this liberty.

In conclusion, black should make the placement before pushing.

That's also an important point in this life and death problem.

But what if black cuts here?

Actually this also leads to ko.

When white blocks, connecting is out of the question.

Black wedges and it becomes ko fight.

This is also a ko, but it's different.

If black loses this ko fight, white can damage black's territory.

But look at this, even if black loses this ko, black won't lose much.

Can you see the difference?

You need to remember to make ko like this, even if there some other ways to play.

If you can play like this, stronger players won't tenuki anymore.

When you study Go, you need to learn some things with certainty and show it to your opponents.

This brings us to the end of lesson 10.

Thank you!
