Episode 22: Practical Test V

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

This is the 22nd episode of this series!

Today, we're going to solve problems based on what we've learned in previous lessons.

That way, you can check out how much you've learned!

Today's problems are from pro's games.

They might be difficult, so I hope you're ready for it!

There's one Go proverb which says, "when attacking, destroy your opponent's shape."

As the proverb advises, you should try to ruin your opponent's shape while attacking.

In the following problems, you'll have to find a vital point. Let's have a look.

There are only few moves on the board.

White played a knight's move here, to take some territory.

Now black needs to attack white's three stones.

However, since these two stones are also weak, attacking white won't be easy.

I'll give you some hints. This is the first choice.

This knight's move is always conceivable when attacking.

Or, you may also think about this move.

Later on, black can aim at separating white. This is also conceivable.

How about this attachment? Black could pressure white like this.

It's a difficult problem, so I advise you to think carefully.

Q. What's the best way to attack white's group?

Hint: Hit the ***** point of your opponent's group.

One difficulty in attacking white is that these two black stones are also weak.

Therefore, black shouldn't attack white hastily.

Because of that, this problem is difficult.

Let's look at the knight's move first.

In response, white can escape with a knight's move.

Or, after attaching here, this counter-hane is a strong move.

In this way, white can counter-attack.

Because of this white stone, the ladder is unfavorable for black.

Since black's position is too thin, black's in trouble.

How about this hane instead?

After cutting, white can rescue her stone like this.

The ladder still favors white.

Black has to atari on this side, then white can capture this black stone.

As a result, white can manage her group easily, while black has many weak points.

Therefore, it's a failure for black.

Since black's position is thin, the knight's move isn't the answer.

How about this attachment then? It looks more aggressive.

In response, white will hane.

This sequence can be expected.

After that, white will push here.

If black hanes, white will hane too. Because of this weakness, black has to connect here.

Then white will play a tiger's mouth. What do you think about the result?

As we can clearly see, white managed her group very well.

In contrast, black's position still looks vulnerable.

In the end, the attachment made white's group stronger.

Because of this, that move isn't the answer either.

In this case, you need to find a move which destroys white's shape.

Here's the answer.

What if white jumps out?

Then black can play a knight's move and separate white.

If white gets separated like this at such an early stage, she'll be in big trouble.

Since there are many black stones, white's groups will be in danger.

Therefore, white should defend here.

After this, black still shouldn't play the knight's move here.

As we saw earlier, white will counter with this attachment.

Or, she can also bump and cut like this.

Since black's very thin, it's a problem.

When attacking, you need to be mindful of your own weaknesses.

Since white defended earlier, black should strengthen his group too.

After that, white will jump out and black can chase her group slowly.

This is more natural. Black can get make good shape in the center while attacking gently.

This is one of the most basic principles of attacking.

Before defending, it's better to hit a vital point.

That way you can get profit first. It's an advanced attacking technique.

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

Hint: Hit the vital point of your opponent's group.

A: 7 points

B: 2 points

C: 10 points.

If you miss the vital point, you opponent will establish good shape.

As a result, you won't be able to attack anymore.

If you study life and death problems and tesuji, you'll learn to spot vital points more easily!

When attacking your opponent's group, you also need to discover your own weaknesses.

In this problem, you need to decide whether to defend by attacking or not.

Let's look at the problem.

Currently white is trying to manage her weak group.

Since there's a weakness here, white should defend with a knight's move.

But white played here to defend more efficiently, forcing black to answer here.

Because of the cutting point, one might think that black has to connect here.

After that, white will jump out like this.

However, this looks like an unsatisfactory result for black.

Do you think it's still OK to play here?

Or can black push and cut like this?

Since this stone can't be captured, it's another possible option for black.

One other option is to jump here and attack white more severely.

These moves look cool.

These are the three choices for black. Please think about your answer.

I'd say this is a difficult problem too.

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

Hint: Prepare to counter instead of ********** to your opponent's move.

Have you thought about it?

White just peeped here.

Let's look at this connecting move first.

After this, white will jump out.

If black pushes here, white will sidestep like this.

After black pushes again, white jumps out. These two stones are light now.

It's clear that white has managed her group very easily.

So this isn't the answer for black.

Compared to the stones black invested, the result isn't satisfactory.

Therefore, connecting there is too slow.

Next, let's look at pushing and cutting immediately.

If white blocks here, black will cut immediately.

And this cutting stone can't be captured right now.

However, what if white peeps here?

Because of this weakness, black has to connect. Otherwise, white will push through.

Even if black captures white's three stones, white gains more in the corner.

Therefore, black can't let white play there. Inevitably, he has to connect here.

Then white ataris and connects.

Interestingly, black's two stones can't escape because of the net.

Of course, it's a disaster for black.

Because of that weakness, black can't push and cut immediately.

In this case, black should attack the entire group. This is the answer.

If white tries to escape, black plays a knight's move.

This cutting point looks a bit frightening for black.

But black can continue to attack, or defend here.

The corner is very safe now.

By attaching here, black can easily secure the corner.

White can survive on the inside, of course.

However, since black got thickness on the outside, he can attack white's other group with this kosumi now.

Since black shut white in and got influence in the center, the attack is successful for black.

Even when you have a weakness, you can still attack very severely in some cases.

This kind of aggressive strategy can sometimes lead to a successful result.

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

Hint: Prepare to counter instead of responding to your opponent's move.

A: 4 points

B: 6 points

C: 10 points.

If you follow your opponent around the board, you'll lose control of the game.

Sometimes you need to play patiently, but that isn't always the case.

Be prepared to counter-attack!

This time, we're going to look at how to attack when you have a thick position.

There are no weakness this time, so all you have to do is attack.

However, when we have a large moyo, we often don't know how to attack.

Let's look at the problem.

These three stones are floating in the center.

It's impossible for white to make eyes at the bottom.

And black has no weakness at this point.

So all he needs to do is to attack white's group.

But, as you can see, this area is very wide, so it's hard to decide how to attack.

Here's the first option.

As we learned earlier, peeping can be good when it makes white heavier.

This is one of the moves you'd come up with first.

It's one way to attack white.

How about attacking white from a distance, like this?

This looks a bit ambiguous, but it's also conceivable.

And I imagine this move is our first instinct.

Black can also attack white with this capping play.

These three moves are the options white could think about.

All of them are good moves, but you need to find the best one.

Let's think about the answer!

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

Hint: Try to stop your opponent **********.

Since all the options look plausible, I think it will take you quite some time to find the best answer.

Let's look at this peep first.

If white connects, black will attack the group by jumping out.

Since the group has become heavier, white has to try to escape. But black will cap here.

In this way, black can continue to attack white.

If white escapes like this, black will cap and aim at this attachment later.

This move will separate white.

So white's in trouble now.

If white connects submissively like this, it'll be wonderful for black.

However, white's more likely to push here instead.

Black has to extend here, then white can push again.

After these exchanges, white can escape with a knight's move.

Since white didn't connect here, black may have to cut and capture white's stones.

Even though black can capture the three stones, white can jump here in sente.

As we can see, the profit is very small in the end.

Compared to the stones black spent, he didn't get enough compensation from his attack.

Therefore, this attack is a failure.

Instead of connecting, white can manage her group lightly like this.

So peeping isn't a good idea in this case.

Therefore, black should aim at the entire group. Let's look at this move next.

Of course, white will jump out here. In response, black can attack the group with a knight's move.

But white will jump again, and this white group is quite solid.

Because of that, white can easily connect.

Black could continue to attack like this, but white's group is more or less safe now.

Therefore, it's hard to say that this is a serious attack.

It's more like chasing and enclosing the center.

However, there's already a stone here.

So I'm not sure whether black's influence will work effectively.

Because of that, this attack is too soft.

Black must prevent white from connecting his groups.

Therefore, the distant attack is the answer.

If white jumps, black pushes here.

After that, if black attacks with a knight's move, it's hard for white to connect to this stone.

Connecting to the other group is difficult too.

If black plays a knight's move here, white won't easily connect.

Since white can't easily live on the inside, all black needs to do is shut her in.

With this attack, white will be in for struggle.

This move prevents white from connecting easily, so it's the best answer.

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

Hint: Try to stop your opponent connecting.

A: 10 points

B: 7 points

C: 5 points.

If your opponent can live or connect too easily, it's better not attack at all.

Prevent your opponent from connecting, so you can attack more severely!

We've just seen some problems from pro games.

I don't suppose it would be easy for you to guess pros' moves.

But I thought these were good examples, so I prepared them for you.

Next time, we'll look at some problems from amateur players' games.

These problems will be easier, so don't worry if you found today's problems too hard!

Thank you!
