Episode 23: Tesuji - Cutting

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

Over the last two episodes, we investigated tesuji.

I imagine you're starting to understand how important the top of tesuji is.

Today, we'll look at more sophisticated tesujis!

Let's begin today's lesson!

We're going to look at cutting tesuji.

Cutting plays an important role in tesuji.

You can't do anything if opponent's stones are all connected.

You can neither fight nor gain profit.

Therefore, people try to cut their opponent's stones apart, to create weaknesses.

The waist attachment tesuji which we learned last time, was one example of a cutting tesuji.

Today, we'll learn a number of other cutting tesuji!

This problem shows one example of a useful cutting tesuji.

This hane is sente.

It's an endgame play.

That means that if black hanes here, white can play the other side.

It's miai.

In this case, cutting here is a very good move!

After that, white can't hane here, because she's too weak.

Instead, she must capture this stone.

Then this atari is sente.

As we can see, black was able to play here, but white couldn't hane.

This is one example of a cutting tesuji for the endgame.

Let's look at some other specific examples.

I've prepared two example problems for you.

Let's look at the top right first.

Black's three stones are nearly dead.

How would you manage this situation?

How about peeping here and playing atari?

If black cuts, he can force white to remove his stones in a capturing race later.

But today's theme is 'cutting'. Can you guess the answer more easily then?

This cut is a nice move!

How does it affect the fate of black's three stones?

If white plays here, black can connect.

Black captures white's two stones.

If white ataris, this counter-atari is a wonderful response.

After that, black can double atari.

White dies again.

So, in this case, this cut is a good tesuji.

The important thing is that connecting here is sente.

Let's have a look at our other problem.

White's moyo is quite big, and these two stones are dead now.

This hane is often played as an endgame move.

White will block here, right?

Can you see anything now?

If you've already found white's cutting points, where would you cut?

At this point, this cut is the answer.

These dead stones make it possible to cut there.

Since white had captured black's stones, she must save her cutting stones.

If white ataris here, black can double atari.

But this move is even better. Black can rescue the dead stones.

White can't connect here.

Because of that, connecting here is the only choice for white.

Then continuing with this move forms a great tesuji combination!

This move is aiming at this atari, then white can't save her two stones.

Can white cut here? No, she can't.

Inevitably, white has to extend and give up her stone.

This hane looks ordinary, but in this case, it's a powerful move.

Therefore, white shouldn't block here.

Instead, this empty triangle is better.

Don't forget these cutting tesuji!

Let's move on to other variations.

They're different to the previous problems.

Since I helped you earlier, I won't tell you anything this time.

In actual games, you won't get any hints.

You have to look into white's position and find a tesuji.

Let's look at the bottom right. Can you feel something inside white's area?

Take your time until you find the tesuji.

If you can see it at a glance, you're talented at reading.

It seems like white's all connected.

But if you find the vital point, you can create trouble for white.

Have you found the answer?

In this case, cutting here is tesuji.

Since white's four stones are very big, white will want to atari here.

Then there's another vital point?

After this cut, you need to read another move.

Did you read up to here?

This combination is great indeed.

If white captures this stone, black ataris.

White has to connect. But how about this situation?

White is now separated.

How about another move?

If white comes out, black can atari here in sente.

It's the same result. White is still separated.

First of all, this cut is a nice move.

And second, this cut completes a tesuji combination.

As a result, white's bottom group is captured.

What if black descends first, without making any exchanges?

Can black capture white? I don't think so.

Even if black squeezes here, he can't win the capturing race.

Let me show you the sequence again.

These two cuts form an excellent tesuji combination.

Let's look at our other problem now.

I won't show you the answer. I hope you can find black's weakness on your own!

Can you see white's cutting point?

Do you think white's stones are well connected?

This cut is the tesuji in this situation.

If you saw this move instantly, your reading is very good.

Capturing this stone is what black anticipated.

As we saw earlier, the second cut forms a combination.

White can capture this stone, but black will split white.

If you can't find the second cut, the tesuji doesn't work.

If black hanes here, white will connect like this.

This hane isn't good either.

If you attach here without cutting, white will connect.

Black can't rescue his stone.

Therefore, black needs to cut here first.

In response to white's atari, cutting here is important.

Likewise, you can sometimes separate your opponent's groups by cutting.

Let's move on to the next examples.

Cutting tesuji help you split opponent's groups and gain huge profits.

This time, we'll look at a different type of cutting tesuji.

White's moyo looks big.

How can we use a tesuji in this situation?

This attachment and cut are a great tesuji combination!

If white ataris here, black counter-ataris.

After white captures this stone, black can connect and separate white.

Now the corner is in grave danger.

White can't play like this.

This atari is the best choice for white.

Instead of moving the stone out, this atari is a nice move.

If white captures, you can atari and start a ko fight.

Or, connecting here is also good enough.

This moyo looks large, but there's a weakness inside it.

Professional players classify the two space extension as thin.

This is because black can aim at such moves.

Don't forget this!

And this combination is also important.

Let's look at the top left corner.

This variation is from a joseki.

In response to white's approach, black played a two space pincer.

After that, white double approached, haned, and invaded at 3-3.

Then black blocked, and white connected.

This tiger's mouth is normal.

Then black exchanges this move.

Up to here, it's a basic joseki.

What if white connects here instead?

Some people might think there's no difference between the two variations.

But if you don't punish properly, you'll lose points.

You should know why this move is a mistake.

Let's focus a bit harder.

If white connects like this, cut here first.

If white ataris, she will lose the corner.

So this connection is inevitable.

After that, this push is a very powerful move.

Can white hane here?

Then black will cut again immediately.

Because of her weaknesses, white can answer firmly.

If white jumps here, this move is sente too.

White needs to defend her weak point again.

This kosumi is essential.

Let's compare this to the joseki.

Which one is better?

Can you compare these two variations?

For black, this variations is better than the joseki.

That's because his moyo is thicker.

Before pushing, black has to exchange this cut.

The result is favorable for black.

Because black's punishment was accurate.

Cutting often enables you to separate opponent's groups or gain some other profit through sacrifice.

In addition, you can punish opponent's mistakes and destroy their moyo.

Cutting is a fundamental element of tesuji.

I hope you worked hard on our lesson today!

1 Minute Summary

We've been studying cutting tesuji.

As I said before, cutting is a basic element of tesuji.

If you don't study tesuji carefully, you can't use them freely in your games.

I advise you to learn other patterns too, if you have time.

We've learned about sacrifice, the waist attachment, and cutting.

Aren't you more tempted to sacrifice your groups, attach and cut now?

That's what happened to me when I first learned tesuji!

And such curiosity will increase your Go strength!

Thank you!
