Hello, it's time for 'Punishing Trick Plays' by Kim Seongryong.

We looked at the 5-4 point last time, and a Go fan sent me some feedback.

He said, "the 5-4 point is too complicated. Do I really have to approach?".

Well, some players just play one side or the other instead, and that's playable too.

However, if you don't approach, you can't learn more josekis.

If you skip over learning something, you'll have trouble keeping up with future lessons too.

So I advise you to learn things one by one. In the end, you'll understand a lot more.

I hope you'll be able to master the 5-4 point with my help.

Let's look at today's theme.

After black approaches, white plays a knight's move.

This attachment is the most common answer.

And white has many possible continuations.

However, this bump and block can become very tricky.

Here's another thing. When white cuts, some players might extend here.

We'll examine these moves.

I'm often asked whether or not black should approach the corner.

Many people don't want to approach the 5-4 point.

That's because there are many more complicated josekis.

That's my opinion.

How about approaching here then? That's a simple move.

You'll be able to avoid complicated variations.

Because white will want to take the corner territory.

Then black extends here.

That's the easiest way to deal with the 5-4 point.

However, white's position is better than black's.

So I recommend that you don't play like this.

If you don't mind taking a small loss, you can choose this approach.

But this approach is normal.

Or, if you don't want to approach, you can also play on the side.

But white will enclose the corner and get a good shape.

So I advise that you approach here.

This knight's move is the most common response.

Many people hesitate about the next move at this stage.

There are two ways to answer.

These two attachments are both possible.

This attachment is played more often.

This bump is one of the answers white can choose.

After that, she cuts here.

And this hane is also possible.

Today, we're going to look at the bump.

This tiger's mouth looks natural.

However, it's something of a trick play and we'll investigate this move today.

White normally cuts or hanes earlier on, and those are joseki moves.

Generally speaking, they're simple, so many players make those moves.

But how about this move?

Since it looks normal, some players would connect here without any doubt.

But if white hanes, black's answer isn't easy.

You need to be aware of this.

This connection seems normal and reasonable, but white will pressure black with the hane.

Surprisingly, black's already in trouble.

There are many ways in which players get into trouble.

Sometimes moves natural, but they're actually trick plays, like this one.

You need to be careful of this kind of move.

White should cut here instead.

In response, black ataris and captures these two stones.

By sacrificing those stones, white can play some forcing moves.

This is a common 5-4 joseki.

After these exchanges, white plays a tiger's mouth.

Then this peep is sente.

After that, black tenukis and the joseki is finished.

But now, white just blocks, without sacrificing any stones.

As I said, black mustn't connect here.

Because then this hane is very powerful.

Black has to hane, and white will extend.

This push is inevitable. White will extend again.

Black's locked in the corner.

White's influence is much better than black's territory.

There's a similar variation, which is a joseki.

In this case, black's territory isn't bad.

However, in this case, black has to crawl along the second line twice.

So this is a great success for white.

The answer is simpler than you might think.

But if you don't know this move, you can easily end up in trouble.

Other moves aren't possible. If black extends or hanes, white will cut and capture this stone.

So black must save this stone.

But connecting here isn't the right way to do so.

In this case, you need to descend here.

If you know this move, there's no problem.

White shouldn't block here.

Black will come out and it's a lot better for black.

What if white hanes, as in the previous variation?

Now it's different. Black can push here.

If white blocks, black can cut immediately.

White has to extend. But when black plays here, white's position becomes awkward.

If white defends here, this peep is black's pleasure.

After that, black will pressure this group, then both of white's groups are in trouble.

So it isn't good for white.

White may play this tiger's mouth, to make better shape,

But black will still cut and it's still not easy to respond.

When black extends, white's shape still isn't good.

Because of the potential throw-in and squeeze, white has to defend.

And then pressing here is still good.

After that, black plays a knight's move.

In addition to taking the corner, black's able to separate and pressure white. It's better for black.

So white won't follow this variation.

This cut is the answer for white.

After this move, there are no more trick plays.

Black has two choices.

If black ataris here, white blocks.

After black captures, white plays a tiger's mouth.

This is a joseki.

After the peep, black tenukis.

In some cases, black can also atari this way.

After exchanging this forcing move, white jumps.

Look at this variation closely.

After white cuts, both ataris are possible.

Instead of connecting, black has to descend here. It's very important.

Remember this move.

It would be a mistake to think that white's tiger's mouth is a simple move.

Don't forget to descend here!

After black's attachment, white bumps here.

I said earlier that the joseki move is the cut.

Then black ataris and captures white's stones.

Never atari like this.

Once white turns here, she has 3 liberties.

Since black has to connect here, it's a big problem.

It's nonsense for white.

So, when you atari, you should be careful.

Don't get confused about which side to atari form.

After that, this exchange is normal.

Then white ataris here.

It's a joseki.

This is relatively simple.

However, black also has a trick play here.

I'll show you.

Instead of the atari, this extension is tricky.

If you're not familiar with basic tsumego, you'll be in trouble.

Blocking here isn't good.

Black will atari and capture white's stones.

Unlike the previous variation, white can't enclose the left side in sente.

Now this hane isn't sente anymore.

So it's better for black.

This is what black wants.

But, in fact, this move can be punished.

This hane isn't good either.

After black captures white's cutting stones, these two points are miai.

It's no good.

This shape is related to a basic life and death problem. First, white has to extend here.

In order to rescue these stones, black must come out here.

After that, block here.

In response, black will hane.

After white hanes, black will connect. Now we've reached a crucial moment.

Because of her cutting points, white can't extend here.

Black will cut.

After these exchanges, black will push and cut.

White has no proper answer.

If white moves this group out, black pushes.

It's a ladder. White's in big trouble.

[Ed: Even without the ladder, white still can't manage.]

Because of the cutting points, many people make a mistake here.

Some would play the tiger's mouth. It's no good.

It's a typical mistake.

If black hanes, white's three will stones die.

And, because black already came out, white's influence isn't very powerful.

In contrast, the corner is large.

Since many players don't answer properly, some people try extending there.

There's one thing you have to know.

It's very simple, so if you learn this you'll never be in trouble.

But if you can't come up with this move, you'll have a big problem.

In this case, you have to choke black's group of liberties from the outside.

If you can play this move, everything will be ok.

Black will hane like this.

He has no other move. This move is impossible.

If white hanes, black's entire group will die.

When black hanes, you need to play this tesuji.

Black has to connect, then hane here.

Black can't play here, because he's short of liberties.

Capturing this stone is inevitable. Then just connect here.

Due to black's shortage of liberties, he has to capture here too.

After that, it seems like white has fewer liberties.

Both sides have the same number of liberties, but black has one eye.

Since white can't play here, she dies, right?

To my surprise, some players just give up here!

But, in this case, there's an excellent move!

You have to know this tesuji to deal with black's trick play.

It's one of the unique aspects of the corner.

This move at 1-1 is possible!

Tesuji like this are one of the things that make Go fascinating.

If white pushes here, thinking she can increase her liberties, she'll never succeed.

No other move is possible now.

Without making any other exchanges, white can capture black like this.

When white blocks, there are two liberties.

It's a ko, and there are no ko threats in the fuseki.

So this black group is captured.

Black's trick play intends to gain approximately 10 points.

But, if white answers properly, he'll lose about 30 points.

If you punish the trick perfectly like this, you can gain 30 points right at the beginning of the game.

Let me show you the whole sequence again.

Don't forget that the move order is very important here.

Let's have a look.

First, you need to extend, and then block here.

Black will hane and connect, to expose white's weaknesses.

Instead of this tiger's mouth, connecting here is the strongest move.

Don't forget this!

Now here's the most important move.

When black hanes, remember to attack black with this move!

With this move, you can reduce black's liberties as quickly as possible.

After black connects, you have to hane.

Black has to play here, then remember to exchange this move.

After that, throw in here. This is the right sequence.

If you can play like this, black will collapse.

Since there aren't many stones on the board in the fuseki, there are no big ko threats.

Therefore, black can't withstand the ko.

Josekis are created during the opening, so black should be in trouble.

I hope you'll learn to play like this and will crush your opponents if they try the extension!

Then you'll gain 30 points from at the beginning of the game!

Now it's time to review an actual game!

We'll look at an online game played between two 6 dans.

There was a very complicated variation (for their level) in the opening.

I think both players knew it.

They played well, but there were better responses.

I'll show you some sophisticated techniques today!

Playing the elephant's step (diagonal jump) like this requires confidence.

Unless you understand what you're doing, it's hard to manage the continuation.

White separated black first.

In fact, that was ok.

But there's a better answer than this.

Later on, white made a mistake, which allowed black to live with many points.

After that, black took control of the game.

Let's examine how white should have played.

In general, the 3-3 invasion is the most common continuation.

This elephant's step is sometimes played by strong players.

Or, those who saw this move in a game might try playing here themselves.

In fact, this move is dangerous.

So I recommend that you don't play like this until you know what you're doing.

This push is the move which black should be most careful of.

How would you respond to this?

In this case, you need to block here.

White will cut here, with fighting spirit. Then black ataris and pushes.

After that, black can take control of the corner.

In exchange for one stone, black destroys white's moyo.

This is the main reason why black plays a large diagonal move.

But it's very dangerous to play this move without understanding the followups.

Please remember this technique!

White can also try to separate black like this.

You need to be able to deal with this move.

In this case, black has to separate white too.

When black pushed, white extended here.

That was a small mistake.

White should have haned instead.

After that, black pushes here.

When black blocks, it's important to atari like this.

After exchanging the atari, black connects here.

It's a compromise between the territory and influence.

The result is even.

Let's have a look at the sequence again.

Separate white first.

After that, white should hane here.

Before blocking, black should exchange this move.

For the safety of the corner, white should play a tiger's mouth.

After the atari, black connects. It's a joseki.

Don't forget this sequence.

Unless you're familiar with these variations, you can't play the large diagonal move.

Here's another one.

In the game, white separated black. But there's a better move.

Because of this move, the large diagonal move isn't played very often.

In this case, this attachment is good.

If black hanes, white extends.

It's similar to another joseki.

But, unlike the other joseki, white's in an attacking position.

Black doesn't have a place to extend to.

Black has to push and attach here. Then white will fortify her moyo.

This variation is better than the normal joseki.

The result is good for white.

So black shouldn't answer like this.

Instead, he needs to block here.

Then white plays a tiger's mouth.

If black connects white will extend here, and look at black's position.

Black's group is certain to be attacked!

In contrast, white's stones are placed at key points.

White's got territory, thickness, and potential for attacking black!

It's very bad for black, of course.

So he has to hane and attack white's stone.

After that, white ataris and captures.

White's position is a lot better than black's.

Therefore, the large diagonal move is rarely played.

It's a move for special circumstances only.

To be honest, black's choice in this opening wasn't appropriate.

This attachment is much more powerful than the other two moves.

The previous variation was favorable for white, so this wedge is an alternative.

It's important for white to enclose the corner after exchanging the atari.

After that, black jumps here. White can't push because of the atari.

Therefore, white has to connect.

When black connects, this peep is a well timed move.

Then both sides defend themselves.

This is the best sequence for both.

But, if you don't know this, your group will be chased, as in the previous variations.

Let me show you the sequence once again.

This wedge is black's best response.

Because of the ladder, white can't atari here.

No one would play like this.

So white has to atari and protect the corner.

This jump is an important move.

This atari would be a bad exchange.

White will block and black's group will be attacked severely.

After this jump, white connects here.

Unfortunately, white has to time to peep here.

Now, if white tries to attack and black cuts, white will be in trouble.

So white defends first and black makes a base.

If you don't understand this sequence, don't play the elephant's step!

The proverb about poking at the 'elephant's eye' (the center of the large diagonal move) doesn't apply in this case.

Instead, I recommend that you play the variation we've just looked at.

There are some moves which are intended to confuse an opponent.

So, in some cases, you might become confused.

But if you follow the right moves, from books, proverbs, and lessons,

You'll become stronger and won't be tricked anymore!

Thank you!
