Episode 21: Practical Test IV

Hello, welcome back to 'Attacking Vitamins'. I'm Lee Hyunwook 8p.

There are many different types of attacks in Go.

First of all, you can seek to gain profit by attacking your opponent's group.

Or, you can attack more severely by playing striking at the vital points.

Last time, we looked at some of the more flexible attacking methods.

Today, we'll investigate how to bully or capture your opponent's group by hitting its vital points.

Let's get started!

Today's focus is on finding vital points.

With this technique, you can take your opponent's base away and attack more severely.

Let's look at the first example.

This is from a pro game.

White tried to settle down by extending along the right side.

You often see this kind of position in actual games.

There are a lot of ways to attack this group. How should black play now?

Since you've seen many problems now, you should solve this easily.

This knight's move is the first option for black.

And how about this capping play, or this attachment?

In general, attaching to a weak group isn't good.

These three moves are the options. Which one would you like to choose?

Q. What's the best move to attack white's three stones?

Hint: Knight's moves and ******* ***** are common when attacking.

Have you thought about the answer?

To be honest, I'm not sure if I can get the answer. It's actually a difficult problem.

Let's see this knight's move first.

White will respond here.

I suppose you saw this sequence in a previous episode.

After this exchange, black tenukis, and this is the most common choice for black.

However, it isn't always be the best move!

It's a bit slack in this case, because black let white settle down so easily.

Therefore, this knight's move isn't appropriate now.

Then what about this attachment? In response, white will hane here.

This extension is inevitable.

After this exchange, white can tenuki, or hane and play a tiger's mouth.

White managed her group very easily.

Originally, it wasn't alive yet, but black helped white to live.

This is the worse kind of attack.

In most cases, attaching to a weak group is a bad idea.

So this capping play is the best answer in this case.

This move in the center is the typical weakness of the diagonal jump.

But if you look at the position carefully, you'll realize that turning here is sente.

Since white can't cut this black stone like this, she needs to answer now.

Then if black plays a knight's move here, there's no exit anymore.

White can't get out here.

Inevitably, she has to jump out.

Now peeping here is important, because black can make white's group heavier.

After that, black takes white's base away by playing this hane.

White has not a single eye. In addition, the hane's very big in terms of territory.

If white jumps out again, black defends his moyo like this.

This is an ideal example of an attack, because black can easily make lots of points while attacking.

When you can play forcing moves like this, the capping play is better than the knight's move.

This is a more powerful way to apply pressure to white's group.

Q. What's the best move to attack white's three stones?

Hint: Knight's moves and 'capping plays' are common when attacking.

A: 10 points

B: 6 points

C: 2 points

You can't always attack your opponent in the same way.

If you look at the placement of the stones carefully, before attacking, your attacks will become more powerful!

This example is also from a pro game.

In this game, black took control of the game by punishing white's overplay.

Let's have a look.

We can easily see that this white group is weak.

Therefore, white should bump or jump like this.

However, white played a knight's move here, to get territory.

I think this move was greedy.

It's important to punish your opponent's overplays.

How should black attack these four stones?

Since the group looks flexible, it seems a bit hard to attack it effectively.

Black has several options here. Let's look at this hane first.

White can't cut here, because black can escape easily.

Because of that, this hane looks powerful.

How about this knight's move? It's the first move we can come up with.

And this is a kind of placement. Black could also consider playing at a vital point like this.

I gave you three options, but you need to read carefully.

Q. What's the best move to attack white's four stones?

Hint: Find a ***** point.

Have you thought about the answer?

To be frank with you, it's a hard problem.

Let's see this hane first. It's the most aggressive move amongst the three options.

Let me assess this move.

White can't cut here, since black can come out.

Now white's in trouble.

After white blocks here, black should push.

Because of the two cutting points, it seems like white's in trouble.

But white can connect here now. Then black should cut.

However, white will atari and destroy black's territory.

This is the expected progression.

Even though black got the corner, his potential on the right side was completely destroyed.

In addition, white gained a very solid position here, so it's a disaster for black.

Because of that, black can't really cut white.

So the hane isn't the answer.

Let's look at this knight's move, which is one of the best attacking moves in many situations.

In response, white will jump out like this.

Then black plays another knight's move, and white moves into the center.

Black successfully enlarged his right side.

However, white settled her group very easily.

Therefore, this attack isn't the best choice either.

If this knight's move isn't the answer, what's the best move in this situation?

This move looks somewhat nebulous.

Nevertheless, it's the answer.

Let's investigate the intentions behind this move.

It seems like white can simply jump out like this.

However, this hane is severe now.

Unlike the previous variation, capturing this stone is huge now.

Black can capture it without suffering any damage.

Because of that, white has to rescue this stone.

Then black separates these two stones.

In doing so, black develops a very good moyo at the top.

White can manage her group, but this moyo will become larger afterwards.

Black got a lot of profit with a powerful attack.

So white shouldn't jump out like this.

Instead, she needs to defend herself.

If white bumps here, this diagonal attachment is sente.

With this, black can develop his right side potential.

At the same time, black can continue to attack white.

Since white can't survive on the inside, she'll suffer greatly from black's attack.

Since this shape often appears in real games, you should remember this move.

Don't forget where the vital point is!

Q. What's the best move to attack white's four stones?

Hint: Find a 'vital' point!

A: 4 points

B: 10 points

C: 7 points

In response to an ordinary looking attack, your opponents will manage their groups easily.

But if you hit the vital point first, your attack will become more powerful!

This example is also from a pro game.

One player achieved a great success by discovering the vital point.

Let's have a look.

White tried to escape with an empty triangle here.

This attachment doesn't work well, because of this wedge.

So this empty triangle was inevitable.

Despite her bad shape, white had captured this black stone, so it was hard to attack her group.

However, if you can find the vital point, you can still attack the group very severely.

Let's look at some options.

This kosumi is the most common idea.

It intends to reduce white's eye space.

Since white tried to escape, enclosing white like this is conceivable too.

The last option is to slide here, but it looks a bit deep.

It could be an overplay, but we can think about it too.

It's time to solve the problem.

Q. What's the best move to attack the dragon?

Hint: Take your opponent's *** ***** away!

If you can get the answer, you're a strong player!

That's because this problem is very hard.

How about this capping play?

In response, white would try to get out like this.

And the problem is that black has too many weaknesses now.

If white cuts here, black has to connect here to prevent a double atari.

After that, white will capture this black stone.

Even though black enclosed the outside, white lived on the inside with lots of points.

The territorial loss is too big for black.

Despite the fact that black got influence on the outside, it's a failure for black.

Therefore, the capping play isn't appropriate in this case.

Instead, it's important to destroy white's eye shape at the bottom.

Let's look at the kosumi, then white will block here.

Even though black tries to attack with a hane, white can easily manage her group.

Connecting here isn't even sente, so this isn't a proper attack.

Therefore, it's impossible attack white with an ordinary move.

In this case, here's a vital point.

The biggest question is what happens when white tries to separate black like this?

However, black can push on the second line here now.

It seems like black's in trouble.

But now black can rescue his cutting stone.

If white blocks here, this placement hits the vital point.

Black wins the capturing race.

Of course it's a huge success for black.

So at this point, white can't extend anymore. Instead, she needs to capture the black stone now.

Then after this forcing move, black can connect.

Eventually, white lost her base. As a result, she had to escape.

In addition, black got many points along the edge.

Since this white group became very weak, black's attack was successful.

It's an advanced, but vital move.

By playing here, black took control of the game at an early stage.

Q. What's the best move to attack the dragon?

Hint: Take your opponent's 'eye shape' away!

A: 10 points

B: 7 points

C: 2 points

When attacking, taking away your opponent's base is important.

Don't miss the vital points!

The focus of today's lesson was finding vital points.

By doing so, you can attack your opponent's groups more severely.

When attacking, it's very important to remove your opponent's eye shape.

When planning an attack, try to discover your opponent's vital points.

I hope you found this lesson helpful.

Next time, we'll look at some other attacking methods with lots of examples.

Thank you!
