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

We've spent a lot of time looking at the 3-4 and 4-4 points so far.

Today, we're going to examine the 5-4 point.

5-4 is often played by strong players.

In fact, many weak players are intimidated when they see it.

However, there are also josekis for the 5-4 point.

If you learn about them one by one, it's not that difficult.

Because of the intimidation factor, many people hesitate to approach the corner.

I've prepared for some variations for them. Let's have a look.

Black approaches, then white plays here.

From the very beginning, white plays on the second line. It's provocative.

However, it's a typical trick play related to the 5-4 point.

We'll investigate this today.

This position arises from a simple joseki.

But if white attacks black like this, how will you respond?

Many people don't answer properly, so let's look at this too.

There are many ways to approach the 5-4 point.

This approach is the most common one.

Or, black can approach like this.

If he plays here, white will take the corner.

After that, black can simply extend here and he's safe.

Those who want to avoid complicated variations choose this approach.

But, in order to improve, you need to learn about other approaches.

In fact, white's position is slightly better than black's.

Therefore, this approach is usually played.

If white tenukis, black can choose any of the usual 3-4 josekis.

In this case, white has lots of options.

Among them, there are some trick plays.

How about this move? When I was young, I found myself in trouble because of it.

If you laugh at it without thinking, you'll get into trouble.

To be honest, this move is somewhat provocative.

Because of that, many players don't read and play blindly. Then they fail.

So be careful.

At this point, anyone would want to move out somehow.

Black mustn't play here. White will enclose the corner.

This can't be good.

It's nonsense.

This attachment isn't a good move either.

If white answers like this, black can separate white safely.

The location of this stone is weird now.

So it's better for black.

However, white will hane here.

Then, if white pushes here, there's no answer.

Black has to separate this stone, then white will push again.

Because of this white stone, black's in trouble.

Also, capturing this stone is good enough for white.

So don't attach like this.

Basically, these moves don't work, so black needs to come out.

How about this kosumi?

Since white's separated, it looks good for black.

But white can attach at 3-3, sacrificing his stone.

If black hanes, white can cut.

After the atari, white moves out. Then black's shape isn't good.

It's none other than the empty triangle.

It's no good.

If black splits like this, white blocks here.

Then black has to capture, and white wedges.

After this extension, it turns out that white's territory is overwhelming.

In contrast, black's moyo is flat.

This isn't good for black either.

Therefore, there's only one move in this situation.

You have to push here.

Of course, white will hane.

You shouldn't block here now.

White will extend and shut black in.

If black attaches, white blocks.

This side is blocked off. It's bad for black.

When white hanes, don't block here.

This attachment doesn't work either.

White will wedge.

After that, black can't expect a good result.

This is the only move at this point.

You have to hane here.

If white extends, this tiger's mouth is wonderful.

Black has to look after his stone, then push here.

After white's extension, you need to block and secure the corner.

Afterwards, black can aim to attack on one side or the other - it's miai.

This is unacceptable for white.

Therefore, this cut is the only move for white.

This move is quite tricky though.

Other moves are impossible.

This atari isn't good because black can't manage both groups at the same time.

So this cut is the answer.

When white comes out, don't capture this stone immediately.

This atari is a forcing move.

After that, white will pressure the corner. It's no good.

There's only one move at this point.

It's the push.

White has no choice but to extend.

Even if white pushes here, black can resist with the extension.

Therefore, one more push is possible.

How should black respond after white answers?

Let's move this stone out!

White can't rescue his stone on the edge.

These three stones are dead.

So, inevitably, white has to jump here and black jumps too.

For starters, black took the corner.

In addition, white is separated. So it's the right punishment against the trick play.

Don't forget this variation!

White might play differently.

What if he ataris here?

If black ataris, white will make a ponnuki.

And this ponnuki is very powerful.

Then how should black answer now?

In this case, remember to attach here.

White has to hane.

Then connect here. This creates a dilemma for white.

If white connects, black will sacrifice the used stone.

Black's territory is huge, despite white's thickness.

If white captures, black simply connects.

This corner is also big.

In response to white's atari, this attachment is the key move.

Don't forget that.

White can't play here.

She can't capture black's stones because of the cutting point.

So it's important to attach here.

If white extends, black has to push here, as I said earlier.

If white ataris now, strike at the head of white's three stones!

White has to capture anyway, but then the shape is worse than with the previous ponnuki.

Let me show you once again.

You're supposed to get into trouble if you're perplexed.

These two moves are essential!

It's so important.

If white pushes like this, just extend.

White can't cut, because then her own cutting point will be exposed.

If white extends, play a tiger's mouth and separate white.

It's better for black.

So don't get confused when you see that move.

These moves are an example of the natural flow of play.

Here's a typical 5-4 joseki.

It's the attachment, which is territory oriented.

Black hanes, and white extends here.

After this tiger's mouth, white usually answers like this.

Up to here, it's a joseki.

White's territory is quite big.

Therefore, it's playable for white.

Black's position is stable, so it's ok for both sides.

In the 1970s and 80s, this joseki was played very often.

Recently, many players jump here instead of playing the tiger's mouth.

This move is mainly played by pros and it's complicated.

So, if it's confusing, I recommend you play the tiger's mouth instead.

However, white has many trick plays in this situation.

I'll show you some.

This is the first one.

Since black can't crawl along the second line, he has to come out.

Crawling is what white wants.

So black has to play here, then white has to kosumi.

After that black pushes and white jumps.

After playing at the vital point, black jumps and stabilizes his group.

This is a joseki.

But some players might try to enclose black here.

It's a typical trick move.

It's not too difficult, though.

Here's an example how black meets disaster.

After these exchanges, some players atari here.

They expect white to connect here, so they can atari and capture white's stone.

But white can counter-atari!

Black has to capture this stone, then white double ataris.

White captures a stone, and the damage here is approximately 30 points.

By the way, a 30 point loss is rarely seen in patterns arising from the 3-4 and 4-4 points.

However, it's kind of normal with the 5-4 and 3-5 points.

Because of that, weaker players are afraid of these points.

They know how terrible the result can be if they make a mistake.

So you need to play carefully.

However, this trick play is no big deal.

Push here first.

White has to block.

Then push again.

At this point, this atari leads to disaster.

But, if you cut here, there will be no problem at all.

If white ataris, you can double atari!

White can't play here because it's self atari.

Then black captures. Of course, black's ponnuki is much more valuable.

Because exerts greater influence over the center.

Therefore, white should connect here instead.

After that, black can extend and the territory is quite good.

During that time, white got nothing.

In contrast, he has to defend his cutting point.

Black takes sente, so it's very successful for him.

It's the perfect punishment.

This is a common trick play.

There's one more thing you should know about.

This large knight's move is quite tricky.

Because of the distance between white's stones, this attachment is tempting.

If white hanes, black can pinch here in sente.

After that, he can come out and it's good enough.

But in this case, white will hane on the inside.

Black has to cut, then white ataris and connects.

If black looks after his stone, white plays a bamboo joint.

Black's group is too weak to attack white.

So this hane is inevitable. White will jump out and black's two cutting stones are floating.

It's no good.

Let's have another look at the large knight's move.

This attachment is impossible. So what else is possible?

Let's look at this again.

It's a one way street.

When white connects, this stone is isolated.

Here's a vital point.

But this atari is a well timed move.

If black hanes, this ponnuki is very powerful.

If black moves it out, white connects here.

Subsequently, black has to turn, then this hane is also powerful.

This isn't good either.

So the attachment is a bad choice.

I'll teach you about the right answer.

If black tenukis, white will kosumi and black's group will be in trouble.

The enemy's vital point is your own - This tiger's mouth is correct.

If you know this, there will be no problem.

If white tenukis, black can separate white safely.

So white has to answer.

Then you can tenuki.

Being first to occupy this big point is great in this case!

White can't attack the corner properly.

If white jumps, black pushes and exchanges this move.

If white connects, black can tenuki again!

This group is still alive.

It can't be captured.

Because black can tenuki after the tiger's mouth, white's large knight's move isn't good.

There's no profit or aji after that move.

Let's look over the sequence again.

If white plays the long knight's move, tenuki after making shape in sente.

Because of this stone, white's influence isn't that effective.

Therefore, if there's a stone around here, this move can be good.

Otherwise, black can occupy this point first.

Don't forget the tiger's mouth!

Once you know how to answer, these trick plays aren't scary anymore.

That's a characteristic of the 5-4 point.

Those who play at 5-4 want you to be afraid and confused.

Don't be afraid, and play as you've learned today.

Then you'll never be in trouble.

Now it's time to review an actual game!

We chose a game played between two 7 dans.

As their rank shows, they are strong players.

However, they made some mistakes during a joseki.

Let's have a look.

Up to here, they played perfectly.

At this point, black extended.

But the extension was problematic.

It's not a joseki move.

So the result wasn't good. Let's examine it.

This approach is common.

It creates good balance with black's top right corner stone.

After white's attachment, black bumped and haned.

Pros also play like this very often.

Therefore, I'd say it's a practical sequence.

White extended. Recently, pros tend to atari here.

After white's connection, black extends.

Or, this tiger's mouth is also common.

However, black chose to push instead in this game.

This is called the 'large avalanche joseki'.

After white's hane, black cut and extended, and it was excellent so far.

At this point, white has two choices.

However, this push is generally played.

After exchanging the cut, black blocks here.

Then this is the expected sequence.

However, they didn't play like this.

Instead of this, white turned here.

In the past, this move was popular.

But at some point, players started to push the other way more frequently.

That's because of the change in the komi system.

In the 1970s, players often pushed like this.

After komi increased from 4.5 to 5.5, players tended to push on the inside more often.

That's because the inside push focuses more on territory.

When white turns here, how do players usually respond?

Baduk N TV developed a database analysis tool.

The players are Baduk N TV 7 dans.

Which move would 7-8 dans choose in this situation?

Let's have a look.

Two thirds cut at A.

However, one in three choose B.

The important thing here is that the next move will change the flow of the game.

And one of these two moves is a huge mistake.

Let's investigate this position.

If black plays a tiger's mouth, white will atari here first.

Then if white blocks, the corner will be captured.

It's a big problem.

The corner is too big.

It's terrible for black.

Therefore, the tiger's mouth doesn't make sense.

Of course, black has to cut here.

After that, white extends.

Then black defends with a tiger's mouth. This is the right sequence.

Then white ataris and double hanes.

After that exchange, black cuts here before capturing white's three stones.

Up to here, it's a joseki.

Since there are no mistakes, it's even.

But the players didn't follow this sequence.

In the actual game, black extended here.

So white blocked here, and now it's too late to rescue the corner.

Cutting here is of no use now.

Inevitably. Black blocked and enclosed his corner.

After that, white extended here in sente.

Let's analyze the result. The top left corner is very big.

Later on, white can reduce black's moyo like this, while expanding his at the bottom.

Therefore, it's very successful for white.

The sequence in the game was a failure for black.

As I showed you earlier, this cut is the proper move.

White can't atari like this anymore.

Since the vital point is here, white's five stones will die.

White has only two liberties.

Therefore, white has to sacrifice her stones instead.

White extends, and black plays a tiger's mouth.

In exchange for the sacrifice, white can play some forcing moves.

After that, both sides capture each other's stones.

This is the best sequence.

I hope you understand this joseki.

This is a variation of the large avalanche joseki. Please try to learn and understand it.

When building a big moyo, sometimes you're afraid of making a mistake.

Because you think the consequence of the mistake will be huge.

Because of that, some players stick to easy josekis.

They usually know a limited range of josekis.

Even if a joseki is long, learning about it can be beneficial to you.

Through that process, you can improve your strength.

In addition, your reading and other skills will be enhanced.

Thank you!
