Episode 19: Practical Test II

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

Your opponents can sometimes be naughty.

Especially when you've invested many moves to build a large moyo.

If your opponent invades and lives easily on the inside,

You'll feel annoyed.

To prevent this, you need to sharpen your attacking skills by working through this series with me!

Let's start today's lesson.

This is a practical problem.

And this is the most basic example when your opponent invades your moyo.

If you remember this, it will help you a lot. Let's have a look.

This is a fairly common situation.

Black deployed a Chinese opening.

Then white approached here.

This high approach is also possible. But let's look at this one first.

In this case, there are several ways to attack white.

I think you've seen this diagonal attachment several times.

This pincer is conceivable too.

And, finally, this is a valiant move. These three moves are black's options.

Where should black play?

Q. What's the best way for black to attack?

Hint: Make white's group *****.

As I said, black has many ways to attack.

I think many people would choose this move.

In a way, this pincer looks obvious.

If white jumps out, black answers here.

Since black has lots of stones nearby, white has no space to extend.

In normal situations, white might counter-pincer like this.

But, in this case, this jump isn't a good choice for white.

Instead, this attachment is a better move.

In response to this hane, white plays a tiger's mouth.

After black's extension, white can make shape.

Locally speaking, it's a joseki. So it should be fair for both sides.

However, this stone looks a bit inefficient.

Above all, white settled down in the corner too easily.

Considering black's previous investment, white lived quite comfortably.

Even though it's a joseki, the pincer isn't an appropriate choice for black.

Therefore, black needs to find another move.

Let's try this move then.

Since this moyo is large, it's tempting.

White will attach here.

This is the expected sequence.

Black can enclose this area.

However, it isn't very profitable for black.

There's still aji here. In addition, white can invade the left side later.

White lived too easily, so it isn't enough for black.

I think many of you found the right answer.

You've played this move many times, and pros also play here from time to time.

This diagonal attachment is the answer in this case.

If white extends, black plays a knight's move.

In response to this jump, black plays here, or makes an iron pillar.

This knight's move is more aggressive though.

White will attach and jump out.

Then black can continue to attack with this jump.

White has to jump out again, but this group isn't alive yet.

So black can keep attacking white like this.

Or he can tenuki and take another big point.

Since this group is still floating, white will have to spend more moves defending it later.

Because of that, white won't jump here.

We often see stronger players slide like this, and this move can be expected.

How should black answer then?

This attachment is a bad move.

White will hane and capture this black stone.

Black can separate white.

But if white pushes here, this group will get hurt.

Compared to black's profit on the left, the damage at the top is bigger.

Black failed.

This kind of slide is often played, so you should learn how to play as black.

In this case, this bump is the right response.

If white extends, block here. Then you can keep attacking white.

After that, black jumps and harasses white.

And black successfully closed off this area.

If white extends like this, black jumps and separates white.

It's very different to the previous variation.

If white jumps out, black blocks here.

Both of white's groups are weak now. So it's painful for white.

In response to the slide, remember this bump.

Q. What's the best way for black to attack?

Hint: Make white's group HEAVY.

A: 10 points

B: 3 points

C: 5 points

If black chooses B or C, white can manage her group lightly.

But if you make your opponent's group heavy, you can maximize the effect of your attack!

The sanrensei is an ideal formation for attacking.

How should we respond to an invasion inside that formation? Let's have a look.

Black was developing his moyo.

At this point, white invaded here.

Instead of this approach, white normally attaches or invades at 3-3.

This approach isn't a proper move in this case.

Let's punish it and show white why it's wrong.

Black has several options.

This pincer is one option. It prevents white from extending.

And this attachment can be considered as well.

This diagonal attachment is our first instinct.

And the iron pillar is possible too.

Since there are many options, you need to take some time to think about the proper answer.

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

Hint: The ******* stones are, the harder they are to sacrifice.

This is a practical variation, so I recommend that you memorize the answer.

Let's try this move first.

In response, white will invade at 3-3.

This sequence is a kind of joseki.

White can live in the corner.

Since it's a joseki, some people think it's ok for black.

However, white settled inside black's area in sente.

Now white will tenuki and take another big point.

Therefore, the pincer isn't the best choice.

When you have many stones, you need to think about a more aggressive move.

So how about this attachment? It looks aggressive too.

Then white will hane.

If black blocks here, white will atari.

After that, white can manage her group lightly.

Even though black secured the corner, white escaped into the center too easily.

So this group isn't a target anymore.

Black focused to much on territory.

You shouldn't usually attach like this when attacking.

I imagine you chose one of these two moves.

These moves are both correct answers.

This iron pillar is a common move.

If white jumps, black plays a knight's move.

This is a normal way to attack white.

However, I'd like to recommend this move.

After this extension, black should normally defend here.

But black has a stone here, so he can leave the corner for now.

Instead, this jump is a good way to attack.

Even if white attaches and hanes, black can easily manage the corner.

Black secured the corner, and white's group is still very weak.

There isn't a single eye, so this group will suffer greatly.

When you have a large knight's move enclosure, you should kick, and then pressure white like this.

Remember this!

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

Hint: The heavier stones are, the harder they are to sacrifice.

A: 10 points

B: 10 points

C: 3 points

D: 6 points

When your target is heavy, your attack will be more effective.

That's because it's hard to manage a heavy group.

This problem is from a pro's game.

This sort of situation sometimes appears in even games.

So it's worth studying. Let's have a look.

White haned here to manage her group.

Black wants to attack white's group now.

Since white haned, this move looks plausible.

Or black can approach here and take away white's eye shape.

And this attachment is also conceivable.

It looks too close to white's weak group. What do you think?

This is a practical variation, so you should learn it.

Let's think about which move is best for black.

Q. How should black attack white?

Hint: Focus on vital points and ****** when attacking.

This problem is harder than the others.

Let's try this hane first.

White will extend, then black has to push.

After that, black needs to keep enclosing white.

How about this? White lived easily.

Even if black hanes, white can survive with this tiger's mouth.

Meanwhile black gained influence on the outside.

However, there's a weakness here.

So the framework isn't that thick.

Since black didn't get much from the attack, it's a failure for black.

In this case, the hane isn't a good response.

So the answer is one of these two moves.

Let's see this approach first. I think it's the most common move.

Then white will jump out like this.

Black can't cut white, because this move is always sente.

Black should fortify his moyo, then white will jump here again.

I think it's playable for black.

However, I feel it's a bit loose. White escaped too easily.

In addition, white can make one eye like this, at any time.

So white wouldn't feel any serious pressure.

Therefore, black should attach here in this case.

It's true that it doesn't look that nice.

If white answers here, black ataris and extends.

Then white can't survive on the inside.

So white has to move out into the center.

Then this move is sente.

After black's jump, white has to push.

Now white doesn't have any eyes.

Therefore, white's forced to jump out like this.

If black continues to attack here, he can build a large territory on both sides.

This is an ideal example of attacking.

This kind of variation is often played, so you need to understand it.

Don't forget to attach!

Q. How should black attack white?

Hint: Focus on vital points and tesuji when attacking.

A: 5 points

B: 10 points

C: 7 points

Vital points and tesuji can destroy your opponent in short order.

So it pays to master certain patterns!

Today's problems were about responding to invasions.

If you memorize certain attacking combinations and patterns, your opponents won't be able to invade your moyo easily.

We'll continue with problems from pro's games next time.

Thank you!
