Welcome to 'Becoming 5 Kyu'! I'm Shim Wooseop 7d.

Reading plays an important role in Go.

However, it requires a great deal of time and patience.

If you play a game without reading, it'll be meaningless.

If you put more effort into reading, you'll increase your strength.

And you'll be able to enjoy games with your rivals.

Let's begin today's lecture.

We'll focus on a basic fuseki.

Once you learn it, you won't suffer as much from unfamiliar openings.

I advise you to use what you learn in your games.

To do this, you need to understand some patterns.

There aren't many variations in this pincer joseki.

So you'll have confidence playing this way.

It's important for white to approach black's corner.

There are too many possibilities with a huge moyo. It's unpredictable.

So, in this case, you should fortify your moyo first.

Wherever white plays next, this solid moyo won't be affected.

After that, black should approach.

This is a simple, and useful joseki.

We've already learned about white's invasion on the right side.

With a 4-4 formation, stones are normally on third or fourth line.

Last time, we looked at white's third line invasion.

Today, we're going to look at an invasion that's common in handicap games.

I guess you've experienced this move many times against stronger players.

Personally speaking, I often play here in handicap games.

Because not many people know how to respond well.

Let's study how black should respond to this invasion.

To stabilize your groups, you may think about these attachments.

But you should erase them from your mind!

Except for in special circumstances, they don't make sense.

You'd better not think about them.

On the other hand, these kosumis are a lot better.

You should consider them first.

Black has two stones at the bottom, and one at the top.

Therefore, you should kosumi this way, strengthening this stone.

This is the move white doesn't want to see.

White has to avoid being enclosed.

In order to escape, white should push or kosumi.

Let's have a look at this move first.

Black should hane without hesitation.

White can't cut here, because this wedge is very powerful.

He can't separate black.

If white ataris, black will just come out.

Because of that, this empty triangle is inevitable.

Black mustn't be greedy here.

This knight's move intends to shut white in, but it's an overplay.

This is a good tesuji for white.

It's the right move order.

Some players might make this exchange first.

This tesuji is still best.

However, black can counter with the attachment in this case.

Therefore, jumping here first is meaningful.

If black tries to cut, white can come out.

It's a one way street.

These moves are all sente.

After that, white can cut here.

If black connects, it's a ladder.

Therefore, an immediate attack is impossible.

There's a famous strategy for attacking.

Have you heard of a 'leaning strategy'?

It's often used by strong players.

If you understand the idea, you can easily do it in your games too.

If it's hard to attack directly, you should lean against another group like this!

If white escapes, you can block here and it's sufficient compensation.

Black's gained more in the corner than he lost from white's invasion.

White wouldn't invade aiming for this variation.

In response to the hane, black simply answers here.

If white comes out, here's another popular move.

Black has too many weak points to enclose white now.

But he can shut white in after pushing first.

Because of the cutting points, this attachment is quite tricky.

This group won't easily die.

In this case, this cut is a nice tesuji.

Of course, white can capture black.

When sacrificing like this, you should add another stone first.

Instead of this atari, black can cut here.

If black ataris, there are no more forcing moves.

But after this atari, white has to come out.

So black will get more forcing moves.

This atari is always sente.

However, black doesn't necessarily have to play it now.

Instead of the empty triangle, this extension leaves fewer weak points.

In this case, the extension is good.

If black becomes solid here, this atari will work.

There's no need to exchange the atari now.

The life and death of white's group will be affected by black's weaknesses.

In this case, black can attack white as severely as he wants.

If there are more cutting points, like this, white will cut here.

After that, this counter-hane is a wonderful tesuji.

If black ataris, white can cut (with atari), then connect.

When white connects, black can't rescue his stone.

This atari isn't possible either, because this stone will die.

However, if black can extend, it'll be different.

This position is more solid.

This counter-hane doesn't work anymore.

In this case, this cut isn't possible either.

Black can capture here without any worry.

If white connects, black will connect too, and separate white.

These four stones are quite big.

This battle is favorable for black.

It's hard for white to escape.

If he can't manage to rescue this group, the damage will be enormous.

So we can see that white's empty triangle isn't a good way to escape.

How about this kosumi?

Since black can't enclose this group, he needs a leaning strategy.

When white tries to escape, don't forget to attach here.

Even if you answer all of the white's moves, you can still attack effectively.

This group is still very vulnerable.

This cut is a good combination.

This atari is fine in most situations.

However, this wedge is an excellent move too!

If white ataris, black can cut here.

Before separating white, black should make this exchange.

This atari is necessary.

Since white's group is separated, the ponnuki isn't very effective.

This group will become something of a burden.

How about this move then? This atari is always sente.

Or black can capture white's stone like this.

But this ponnuki looks quite good in this case.

So black should save his stone instead.

Then black has miai.

If you remember this kosumi, you can easily take control of the game.

Let's move on to the practical tsumego lesson.

This position appears quite often.

We've already learned about the 3-3 invasion.

Depending on the situation, black might block here, to secure the right side.

So instead of the invasion, white can peep here.

Connecting here is the most common answer.

Or black can block here. There are three possible choices.

This connection is a normal response.

White has to decide where to push.

If white plays here, black can hane or secure the corner.

This hane is a simple answer.

Pushing here now is a bit heavy.

Instead, sliding is a good move.

If black attaches, this move isn't good, because of the double hane.

White can easily live with the extension.

Followed by the tiger's mouth.

These two points are miai.

Let me show you another variation.

This hane allowed black to live so easily.

How about this move?

Thanks to the previous stones, white can make shape.

What if black shuts white in like this?

I guess you've seen this variation a few times, right?

After creating some weak points, white should attach here.

Other moves will make black thicker.

This combination is very useful.

So you can widen your eye space.

Because of the cutting point, black can't hane here.

In this situation, black needs to protect his weak points.

In life and death, making a tiger's mouth is often very important.

After this move, the group is completely alive.

This peep is another good invasion.

It's conceivable if you don't want to hurt your top group.

Sometimes other moves are played.

This connection is the simplest answer for black.

But black can also block here.

Let's have a look at this move.

If black connects, it's the same shape as on the left.

However, black can extend here now, aiming to make life difficult for white's group.

So instead of moving it out, white should invade again.

If black captures this stone, white can escape.

This peep is another good invasion.

Depending on black's answer, white can choose to rescue his group or sacrifice.

I'm looking forward to seeing you again next time.

Thank you!
