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

There are many trick plays related to the 3-4 point.

We've already examined some variations that start with attachments.

However, there are many trick plays that can occur when a pincer is played too.

There are various types of approaches and pincers.

Today we'll look at pincer attacks on high approach moves.

Many trick plays are derived from them. Let's have a look at today's topics.

In response to black's high approach, white pincers.

Some people like this pincer because they hope it will lead to unexpected profits.

That's because there are many complicated variations after this pincer.

When black plays a large knight's move, this large diagonal move is a kind of trick play.

We'll investigate it.

This attachment is a common move.

But when black bumps, this empty triangle is another famous trick play.

Let's look at this move too.

When black approaches, this pincer is played quite often.

After that, this jump is possible.

However, the majority of players choose this large knight's move.

In general, people who play here know the normal joseki very well.

But, instead of this attachment, some people play here.

It's a definite trick play in this pincer position.

When I was young, and getting stronger, my opponents would sometimes play here.

However, when I first saw this move, I was very confused.

You may want to separate white, like this.

But then, when white splits black, this pincer is well placed.

Black is likely to experience a failure here.

This push is powerful. So black can't expect a good outcome.

The placement of the pincer is too good. Black should choose another move.

Obviously, black has another choice.

This move is possible, and it's the proper answer.

When white pushes, black mustn't block here.

Now these two stones are in trouble. It's no good.

Therefore, you should come out like this instead.

White will split.

My teacher taught me a simple move for this situation, in case of confusion.

So I'm showing you this move now. If you feel uncertain about this position, remember this move.

Black can simply hane here.

If white descends, then capture this stone.

Then this sequence can be expected.

Well, it's slightly better for white.

So, to become stronger, you need to know another move too.

This hane requires a bit of courage.

If white falls back like this, the exchange is very profitable for black.

If white blocks, black doesn't have to answer in this case.

If white moves it out, you can capture these stones by jumping here.

However, once you hane here, you have to respond when white descends.

If black tenukis, white can extend.

If white plays here, black's entire group will be under attack.

White will be able to take the corner, so be careful.

As I mentioned, you should master the hane to become stronger.

White shouldn't block, because it's gote.

White has to defend the cutting point, and the corner is secure.

Therefore, white should descend here.

After that, white will play here. This is a crucial moment.

Many players kosumi here.

But this knight's move is a nice response. White doesn't have to rescue these two stones.

After black defends, the corner doesn't look that big compared to white's thickness.

White can develop large frameworks on both sides. It's an ideal variation for white.

If black tenukis, white will jump here.

It's not even clear which side is attacking now.

Black may have to capture white, by playing many moves in the corner.

Moreover, black's whole group could find itself in trouble.

So you need to learn the proper response.

I've seen some players kosumi here.

It's a bad move.

Just to start with, black can't escape anyway.

Some play here, to try to gain more points in the corner.

But then white will kosumi and live in the corner. It's terrible.

This attachment is the best move.

It's a lot better than this kosumi.

Because black still needs to spend another move in the corner here.

Instead, you should choose a move which completely captures the corner.

The answer is this attachment.

If white plays here, black pushes, then blocks.

If white extends, there's no need to defend the corner anymore.

The difference between these two moves is huge.

White can't increase his liberties when black attaches.

So white should attach here instead.

Black hanes, then white crosscuts.

After that, this atari is a proper move.

Subsequently, white plays some forcing moves.

Up to here, it's the best sequence for both sides.

The corner is worth about 20 points. It's quite big.

Please learn to play the correct sequence.

It's one of the most complicated variations in the pincer position.

So you need to be well prepared for this move.

If you know how to deal with this, you can play the large knight's move without reservations.

Remember to separate white like this.

If you know how to counter it, you won't be tricked here.

When black plays this large knight's move, there's another famous trick play.

As expected, white attaches here.

After exchanging this hane, black bumps.

Here's the joseki I learned many years ago.

At that time, black played a tiger's mouth here and it was considered to be joseki.

After that, white hanes and then extends along the bottom.

It hasn't been played recently, because it's better for white.

Instead of the tiger's mouth, black pushes here.

Then he plays a tiger's mouth like this.

After white extends at the bottom, black tenukis and this is a newer version of the joseki.

In contrast, this isn't regarded as joseki anymore. It's old-fashioned.

This joseki is relatively simple.

This empty triangle is the trick play.

If you haven't seen it before, you might feel confused.

Let me show you white's intention.

When this liberty is open, white can't cut black.

If white does so, black can atari here.

Even if white kosumis, black can resist.

I'll show you the expected progression.

As I've said many times before, crawling along the second line isn't good.

So white can't expect a good result like this.

However, white has another move.

What if white plays like this?

When white double hanes, black's cutting points are exposed.

If black falls back, white's already successful.

Compared to the joseki, white's better.

Let me explain why.

If black plays a tiger's mouth, white will enclose black.

This move isn't sente anymore.

In this case, this knight's move will be very painful for black.

Therefore, black can't extend like this.

Capturing this stone isn't good either.

White will cut and separate black.

Black's two stones became useless.

It's a huge failure.

Let me show you the proper response. You'll need to learn about this sequence.

Otherwise, you'll suffer every time white plays like this.

Remember to cut here first.

When white plays here, connect.

White has no choice but to cut.

This atari is obvious. And this is a crucial moment.

You must extend here, nothing else is possible.

If you plays a tiger's mouth, there's no answer after white extends.

This knight's move doesn't work.

Because this attachment is an excellent tesuji!

If black extends, the entire group dies.

Black can't connect here either.

It's a disaster.

Therefore, you must extend here.

At this point, this tiger's mouth is the only possible move.

White has to be careful too. He can't live if black hanes here.

So this hane is necessary.

Black shouldn't connect like this.

After this throw-in, white will jump.

When black secures one eye, white can't connect here.

Because this throw-in is a nice move.

After the atari, white can't save this stone.

If white hanes here, a ko will start.

Since white has no ko threats, it isn't good.

Because of that, white has to look after her corner.

So, after this exchange, white shouldn't play here.

Instead, she needs to push and connect.

It's a vital point.

Then black has to capture this stone.

After that, white can rescue her group.

However, black has a better move.

In this case, this move is nicer.

That's because white enclosed black in the previous variation.

Black can move out this time.

It's a one way street up to here.

This move is impossible, because black can throw in and then white will die.

Therefore, white needs to connect here.

Living like this isn't a good idea.

Instead, black should clamp here.

Because of white's cutting point, white can't separate black.

Inevitably, white has to rescue the corner.

Then black captures this stone. It's better than the previous variation.

This is the perfect punishment against white's trick play.

Even though the sequence is long, you should study it.

Then white won't get away with playing like this against you.

Now it's time to review an actual game!

We'll investigate an online game played between two 8 dans.

Both players made mistakes in the opening.

There was a variation which we studied. Let's have a look.

When you have a stone nearby, like black's stone at the top, there are several possible ways to play.

Black chose to pincer and this attachment was a strong move.

Later on, white made some mistakes. Let's have a look at that sequence.

There was a peculiar shape in this game.

Look at the top left corner. Black played at the 3-4 point.

In the top right, he played 4-4. This isn't the sanrensei, nor the Chinese opening.

It's an ambiguous move. But black chose it anyway.

Well, I'd say it's still a playable formation though.

After that, white approached here.

There was a black stone at the top.

This should affect black's choice of joseki in this corner.

Normally, the simplest response is the knight's move.

But, in this situation, black has more choices.

We used a database analysis tool.

And we looked at 20,000 games played by Baduk N TV 7-8 dans.

Let's see what the most common moves are in this sort of situation.

39% of players chose A, while one quarter played at B.

And the rest of the players chose C, D or E.

The most commonly played move is A.

Let's change the group. We're looking at 9 dans now.

The percentage of plays at A has increased.

15% of players played at B.

14% of players chose C. That's more than I expected.

Professional players wouldn't attach at C.

It can be seen again that amateur players like the attachment at C.

Not many players simply answer at D.

The knight's move isn't often played in this kind of position.

Let's see the actual game. Black chose the most common move.

Normally, white invades at 3-3 now.

Then black blocks here and builds a big moyo on the outside.

He'll keep expanding the moyo afterwards.

White will approach, and try to erase black's influence.

It's clear that black's playing for thickness, and white's playing for territory.

This is a common variation, but white didn't follow it.

Instead, she jumped, and this is also possible.

Normally black jumps, then white presses here.

The sequence up to here can be expected.

Black gained territory in the corner this time.

In contrast, white got thickness, limiting black's potential.

However, black chose rather a severe move.

He attached here.

If white extends, black will jump.

And this is also possible.

However, white made a mistake in the actual game.

After she jumped, black attached.

Then this hane was a very bad exchange.

Instead, white should've bumped and played a knight's move.

Or this kosumi, or this attachment. Anything would have been better than the hane!

Black blocked after white haned.

And this atari was another bad exchange.

Because of the hane, white couldn't connect here now.

If black jumps, the aji in the corner is significantly weaker than before.

Let's analyze it again from the beginning.

At this stage, it's the same as white if had pushed here now.

But, if white doesn't push, she can at least jump here now.

That's why she had to play another bad exchange.

In conclusion, this hane was bad.

Because of this, white had to atari.

Consequently, white helped black to secure his moyo.

Black easily made 30 points at the top.

On the other hand, white still couldn't attack black's stone properly.

How about this move?

After exchanging these peeps moves, black will jump out.

This attack isn't powerful at all.

Black easily consolidated his moyo at the top.

In contrast, white's position wasn't solid enough.

So, when black attaches, this bump is the only move.

After that, this kosumi is good enough.

Or, this attachment is also powerful.

If black pushes, this cut is a well timed move.

There are so many forcing moves.

White can easily fix up her shape.

So remember the proper answer!

We've been studying trick plays related to the 4-4 and 3-4 points.

3-4 seems more complicated.

But 4-4 can also be confusing sometimes.

Since the 4-4 point is most common, you should learn about as many variations as you can.

And, as you become stronger, you'll face the variations of the 3-4 point too.

So you need to learn about both points.

If you can understand many variations, you'll improve a lot.

Thank you!
