Episode 22: Tesuji - Waist Attachment

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

A game of Go is divided into the opening, middle game and endgame.

We've already learned about joseki and fuseki, which are opening skills.

Once the fuseki ends, you may find that you sometimes have no idea where to play.

From that time onwards, you need to rely on reading.

You can draw large frameworks in the fuseki.

And you can reinforce them with accurate reading in the middle game.

If you think about this for a while, you'll understand how to manage a game.

In order to improve your reading, you should learn tesuji.

If you study tesuji, you'll understand Go better!

Today, we're going to look at the waist attachment.

The term 'waist attachment' refers to this kind of move, which cuts across white's knight's move.

Suppose there's a black stone here.

This isn't the waist attachment, but this one is.

And now both sides will fight against each other.

Let's imagine black has a stone here.

This is just a push and cut.

On the other hand, this is the waist attachment.

This kind of move is played to cut your opponent's groups.

Let's look at these examples to better understand the concept.

Let's have a look at the bottom right corner first.

This variation is from a 3-5 joseki.

In response to this approach, white answers here.

After black blocks here, white tenukis, then black extends.

Actually, white should have played a kosumi here, to protect the corner.

But what happens if she tenukis?

This is the waist attachment.

Let me highlight this move.

Where should you play after the attachment?

As I said earlier, cutting here is the answer.

If black blocks here, white's stones will die.

So white has to capture black's stone.

Let's exchange the atari here first.

After white ataris, black cuts here.

If black's thick in this area, he can block here right away.

Otherwise, this extension is also fine.

Later on, black can harass white with this placement.

This is a life and death problem, so we'll come back and look at this later.

The main point is that there's still aji in the corner.

And by sacrificing this stone, black can shut white in.

White probably won't like this variation.

So defending with this kosumi is necessary.

Let's compare the two variations.

As we just saw, this combination is a good punishment.

White's forced to capture this stone.

Compare this with the joseki.

Of course, this result is much better for black.

By sacrificing one stone, black can enclose the corner.

Now let's look at this example.

It's a practical position.

Black approached white's enclosure first.

After that, black played a knight's move.

Generally speaking, this move is very thick.

Let's investigate why that is.

In response, white jumped here, and the corner looks big and secure.

However, white's position has a weakness.

This attachment is a tesuji!

White has to separate black, then black cuts here.

White has to capture black's stone. How about this atari?

Then black will atari and separate white.

In order to connect, white needs to play here, but it's no good.

Therefore, this extension is the proper move.

Black can't save his stones like this. They're dead.

However, he can sacrifice them and harass white.

This move is wonderful!

If white falls back, black will connect and gain many points.

In addition, black built a solid wall on the outside.

It's a big success for black.

How about this move then?

Then black connects, to sacrifice his stones.

In order to capture black, white has to reduce black's liberties.

At this point, there's another nice tesuji.

This first line placement is excellent!

Can you come up with this move on your own?

If white separates like this, black will play here.

Attaching here is common.

But, in this case, black was also able to exchange this move, which is a bit more profitable.

Though it might seem small, it's better for black.

Anyway, the main point is the waist attachment.

And this move completes a wonderful combination.

Both moves are good tesujis.

Remember both moves so you can profit from these tesujis in your games!

Now let's look at the last example.

White's group is very weak.

To apply some pressure to this group, black played a knight's move.

Many of you would play a tiger's mouth and extend here, to look after white's group.

But before playing like this, you need to look at the position closely.

If white plays like this, black can shut white's group in.

Where's the tesuji?

As we've learned, this attachment is the answer.

White has no choice but to capture this stone.

This atari is a forcing exchange for white.

But then this counter-atari is great.

White has to capture this stone, then black can cut here.

Since white's group is in danger, she can't start the ko.

If white falls back, black connects here.

How about this variation? White survived in the corner.

However, black's position became thick and solid.

So it's a success for black.

All the examples we've seen today are based on the waist attachment tesuji.

In addition to learning this tesuji, the followups are also important.

If you master them, you'll be able to take profit or seal your opponent's groups in.

When your opponent plays a knight's move, look at the position carefully.

Let's see some other tesuji!

We're going to investigate another example of the waist attachment.

White peeps with a knight's move.

If black connects here, this move is sente too.

Black has no choice but to connect again.

And after this extension, black's entire group is in danger.

The knight's move aims to cut here.

It's a nice move because it removes black's eye shape.

If black connects, white will extend here after playing another forcing move.

White's attack is very severe.

How should black manage this situation?

The waist attachment can also be used in this case.

Before connecting, playing this move is wonderful.

Let me highlight it.

If white cuts now, her stones will die.

Inevitably, she has to capture this stone.

Then black ataris here.

To sustain her attack, white has to capture this stone.

After that, black can play a tiger's mouth here.

In the previous variation, white played two forcing moves, then extended here.

But, thanks to the tesuji, black took sente.

After taking this vital point, black escapes from immediate danger.

Now let's look at this position.

This is based on a joseki.

As an endgame play, white can slide here.

If white just plays this knight's move, black can simply attach.

We saw this move once before. Do you remember?

How about this bump?

After black blocks here, white can peep later.

In addition, white got sente.

In this case, this attachment is a nice move once again.

Black's aim is to sacrifice his single stone.

Then black can atari here in sente.

Which side gained sente? Black did.

So he can defend his moyo.

Or, playing another big point is also possible.

The waist attachment on the second line can help you to take sente.

This is another characteristic of the waist attachment.

Here's a final example.

After this initial approach, white approached here immediately.

In response, black pincered.

This is a common trick which stronger players sometimes play.

After exchanging the peep, white tries to enclose black immediately.

Black has to push and cut.

However, this double atari is very bad.

If black captures this stone, white can enclose this area.

White can develop solid influence on the outside.

In response to this atari, white sacrifices her stones.

Black's territory is large, but white's influence is massive.

This is a common trick play.

You can punish white by playing the waist attachment!

Cutting here is what white wants.

But attaching here spoils white's plan.

What's the aim of this move?

In the previous variation, black gave white huge outside influence.

In this case, if white extends, black can suppress this white stone.

After that, white can't shut black in.

What if white hanes here?

If black cuts, it will be the same as before.

But this counter-hane is a wonderful move!

If white cuts, black connects and moves out like this.

In order to rescue her 4 stones, white needs to play around here somehow.

But black will atari and block here.

This hane is sente, and white's bottom group is in trouble.

How about this push then?

After this extension, white has to atari here, because of the ladder.

Then black blocks here.

White's group is too weak to fight.

So this combination is very good.

Now white has no proper answer.

If white pushes here, black will move out and it's the same.

And in response to this extension, black captures the cutting stone.

It's a huge failure for white.

This attachment is the perfect punishment!

If stronger players play like this, don't forget to attach here.

After that, just smile.

This is the end of our lesson on the waist attachment tesuji.

1 Minute Summary

Today we learned about the waist attachment.

It can help us to make shape, to attack, and to rescue groups.

So it's a very useful move.

However, there's one important thing you should remember.

After attaching, don't forget to cut immediately.

If you don't cut, the waist attachment won't be useful.

In many cases, this attachment is good.

But you need to remember some things.

Firstly, think about whether you can cut here or not.

If not, it's too early to play the waist attachment.

Secondly, if you want to fight, you have to check the potential ladder.

This stone mustn't be captured, because it's a very important cutting stone.

Because of that, you need to consider the ladder before cutting.

Sometimes, the waist attachment is played as a sacrifice.

In those cases, you can cut and atari like this.

But if you want to fight, you have to check the ladder.

So those are the two things you should consider before attaching.

First, check the feasibility of the cut. Second, read the ladder.

And a third possibility is that you sacrifice this stone, atari and extend.

If you know all of these techniques, you'll be able to use the waist attachment effectively.

We'll explore more tesuji next time!

Thank you!
