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

Have you heard of a book called the 'Encyclopedia of Joseki'?

When I was young, that book was popular.

It was peculiarly thick!

I wondered how people would be able to hold that book in their hands and read it.

There are many josekis in that book, more than 30,000 in fact.

However, about 20,000 of the josekis arise from the 3-4 point. Don't forget this!

The variations of the 3-4 point are very difficult and seemingly infinite.

We're going to learn about some basic trick plays today. Let's have a look.

In a one space pincer position, black can attach and extend.

It's one of several possible choices.

When white bumps, black plays a knight's move, which is a trick play.

It looks like a reasonable move, but there's a dangerous trick hidden behind it.

In response to this high pincer, this two space jump is common.

How should black answer if white attaches and counter-hanes like this?

We'll also look at this variation.

In response to this approach, white pincers.

Since the pincer is very tight, a battle could erupt early in the game.

With this sort of pincer, both players have more choices and more things to consider.

In this case, neither side has many choices, which could lead to early fighting.

We talked about this knight's move last time.

Today we'll investigate this attachment.

This attachment is also played when white's corner stone is on the 4-4 point.

Therefore, it's a basic and useful move.

Normally, white hanes, then black extends like this.

Then white jumps here, and black cuts.

It's a basic joseki.

This extension is a bit more complicated.

When white bumps, black extends.

Let's see some more moves.

White's previous move aims at black's weak point.

So black attaches here, to defend it.

After that, you should think about this extension, which is sente.

White has to hane or extend.

Then black attaches.

Instead of this, black plays a knight's move.

This looks like a normal move.

But it conceals a powerful aim.

To begin with, this hane doesn't work.

This is a typical example of failure.

Because of the exchanges black made earlier, there's a cutting point here.

Therefore, white can't protect both cutting points at the same time.

So white's in trouble.

So you mustn't hane in this situation.

Because black didn't answer, some players might be tempted to play here.

Instead of looking after these two stones, black will apply pressure to the corner.

If white attacks them, black will capture the corner.

These stones have already been used up, whereas the corner is valuable.

Black's already made 15 points, so this stone is precious.

Despite the number of stones, this white stone is much more important than black's two stones.

So white shouldn't push through like that.

This push helps black.

Let's compare it to the original variation.

When black extends, white should play a knight's move like this.

But no one would bump here.

So you can see how wrong white's previous move is.

So we've seen some bad moves.

How about pushing here then?

After that, this jump seems plausible. But that's what black wants.

White will be in big trouble.

In this case, this extension is a great move!

After that, this cutting point is exposed.

If white plays at 3-3, black will cut and capture white's two stones.

The extension plays an important role in this case.

As a result, these pivotal stones are dead.

What if white defends her cutting point?

Then think about the meaning of this stone.

Black pushes and cuts.

White can't let black capture her stone in a ladder.

It's a ladder and this stone is huge.

So white has to connect, then black pushes here.

If white moves out, black pushes again.

Do you remember the 'tombstone squeeze' tesuji?

When white blocks, it seems like black's liberties are too few.

If black hanes, white has five liberties.

Since black has only three liberties, he dies.

But, as you might know already, black can cut and sacrifice.

White has no choice but to capture this stone.

When black plays here, white still has to atari like this.

Black ataris and lets white capture his stones.

When black throws in, white has to capture.

That's why white can't get more than three liberties.

White's group dies. This is the very variation that black was aiming at.

Nevertheless, black's trick play looks plausible at first sight.

But this is black's aim. Don't forget this.

Many players answer normally, without any doubts.

But if you push and jump, it will lead to disaster.

When black extends here, white's already in trouble.

How should white answer then? Let's punish the trick play!

Remember to push one more time!

Surprisingly, there's another trick play here.

When black plays here, many players would defend the cutting point.

Then black shuts white in the corner, acquiring influence on the outside.

You need to be careful of this variation.

It's another trick play.

I'll show you the correct answer.

In this case, just peep here.

Because of the cutting point, black has to connect.

After that, strike at the head of black's two stones!

What if black cuts? Yes, white's two stones are dead.

But this jump is a wonderful move!

If black blocks here, white can atari and sacrifice her stones efficiently.

These stones aren't important now.

White's already exploited them thoroughly.

This extension is the best response for black. Then white tenukis.

White's territory is very big, so it can cover the loss of her two stones.

This is the perfect punishment against the trick play.

As I said earlier, you mustn't try to save these stones.

Because of this move, white will be in trouble.

In this variation, there are two trick plays.

The punishment requires you to sacrifice, and maintain a solid position.

Don't forget this!

What's the most common move after this approach?

I'd say that there are three answers.

Instead of a pincer, a defensive move can be considered first.

This move is called "Shusaku's kosumi".

Approximately 150 years ago, Honinbo Shusaku made this move the centerpiece of his fuseki.

It's retained its popularity to this day.

And this two space high pincer, and the three space low pincer are also common recently.

These three moves are the most popular responses.

Today, we'll look at this high pincer.

In response, this two space jump is the most common move.

When moving out into the center, a one space jump is normal.

On the side, a two space extension is common, when you already have a single stone.

In this pincer position, this two space jump is the most common answer.

Then white will usually play a two space jump too.

After that, there are many possible variations.

But how would you respond if white attached and haned like this?

It's another trick play and we'll investigate it today.

We need to become familiar with this move. It's more complicated than it looks.

Some players may become confused, and just cut.

But they'll face some problems.

This is a typical example of failure.

Black doesn't know how to play now.

He'll atari, hoping white will answer as he wishes.

If white comes out, black can push through and connect here.

If you come up with this sacrifice strategy, you're a good player.

However black has a one sided imagination.

White won't respond like that.

If you see this plan, perhaps you'll be impressed by your reading.

But white has a wonderful counter.

This counter atari is the move!

After that, the flow will change.

White's about to sacrifice her stones instead of black.

Black has to capture, but he can't win a ko in the fuseki.

Inevitably, he has to connect here. How does it look?

It's a rabbity six shape, which is even worse than an empty triangle.

This is the worst situation.

White will just connect here.

Black has to hane and push.

Then he needs to jump out.

White captures this stone. White's territory and influence are so great!

It's incomparable to black's moyo.

This is a disaster. It'll be very hard to recover from the damage afterwards.

What went wrong?

The atari? No, black had already made a mistake.

After that it was a one way street.

In general, white extends when black hanes.

Then black jumps and white cuts.

Up to here, it's a joseki.

If white doesn't follow this variation, it could be a trick play or an overplay.

Where was the overplay?

If you think this attachment is it, you're wrong.

This move is normal.

But this hane is a huge overplay.

If you cut here without thinking, you're already in trouble.

You have to be very careful at this point.

What's the right answer then?

If you cut here, you'll fail.

You'll never punish white's overplay like this.

You need to know this atari.

White has no choice but to connect.

After that, separate white.

If you don't rescue this stone when white cuts, everything will be fine.

Some players get into trouble because of this move.

In this case, just sacrifice your stone!

This atari, or this connection, is good enough.

Do you think this black stone is big? What about the corner?

As a result of the ponnuki, white got a bit thicker.

In contrast, black took the entire corner.

Black already secured 20 points, while white got five points at best.

Black's better. There's no need say it.

Therefore, white would think of this cut instead.

How should black respond?

In that case, you shouldn't play to capture white's stones.

That's white's intention.

White will sacrifice her stones.

All these moves are sente.

If white ataris like this, her moyo is quite good.

Therefore, you shouldn't capture white's stones.

At this point, you need to be patient.

This connection is the best response.

Some people might say that white can capture black's stone.

In that case, it's time to sacrifice!

After that forcing move, atari here.

There are a few more forcing moves here.

White captured three stones.

But it's nothing.

White only got a little more than ten points. How about black's influence?

It's a big failure for white.

So don't forget this.

When white cuts, don't try to capture white's stones.

After the atari, this connection is the key move.

If you know this, white's in trouble.

Remember this.

When your opponent overplays, you have to calm down.

If you rush to punish them, without reading, you'll get yourself into trouble.

That's because your opponent already knows the tricks.

Now it's time to review an actual game!

We'll look at a game played online, between two 7 dans.

In this game, they were playing the joseki we learned last time.

But the result was very different.

I'll point out their mistakes.

Black's 3-3 attachment is the same as the one in our last lesson.

After the cut, white extended.

In response, black haned.

Instead of defending the cutting point, white jumped like this.

It was clearly a mistake.

After that, both players exchanged mistakes. Let's have a look.

This 3-3 attachment is a territory oriented move.

We can surmise a little about black's style, based on that move.

I explained to you that white has several choices here.

Let's use our database analysis tool.

We'll look at how amateurs and pros would respond in this situation.

Let's see what the most common moves are.

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

Which move would they choose most often?

The majority of players bumped at A.

22% of players chose B, which is another joseki move.

How would pros play here?

The vast majority of players played at A.

As I said previously, B is an old fashioned move.

It used to be played fairly often, but not recently.

We can see that most pros play at A in this situation.

After the exchange, white has many choices.

He can cut, atari, or extend.

Where would Baduk N TV 7-8 dans play here?

The majority of players ataried at A.

26% of players chose B.

Also 26% of 7-8 dans played at C.

Let's look at pro's choices.

83% of pros played at A.

Compared to amateurs, not many players chose B.

However, 7% of players chose C, it's more than I expected.

In the actual game, white cut here.

After that, this extension is the only move.

I said that, when black hanes, white should connect here.

If the ladder favors black, he can block here.

It works when the stone in the bottom right corner is placed on the 4-4 point.

If white comes out, black has to block.

When white pushes, black should be able to reduce white's liberties.

However, the stone in the corner is placed on the 3-4 point.

In this case, the ladder favors white.

If the stone were on 4-4, the ladder would be favorable for black, but it's not in this case.

Black's in trouble now.

Because of that, white should've connected solidly.

In this case, black has to kosumi instead.

To defend the cutting point efficiently, black should push here.

After that, white captures the corner, and black ataris like this.

Up to here, it's a joseki.

But white didn't follow this variation.

This jump was a big mistake.

Consequently, black captured white's stone, and white jumped here.

At this point, black made a mistake too.

This push was problematic.

Instead, he should've just captured this stone.

White will capture black's two stones.

However, black's push and cut is a good combination.

Even though these two stones are dead, black got a nice moyo on the left.

It's successful for black.

Black's push was a mistake.

This hane was powerful.

Then black moved his group out and fixed his shape.

But these forcing moves were painful for black.

White's shape looks quite good.

Black was supposed to succeed here.

But this push was greedy.

He wanted to take sente, but it was wrong.

By capturing this stone, he could've got a larger territory.

When white blocked, black had no proper answer.

Inevitably, he moved his stones out, and this group became heavier.

However, white had a better move.

She should've sacrificed one more stone.

As a result, white could've connected in style like this.

But she just sacrificed one stone.

Because of that, she couldn't fly out like before.

After that, black looked after his group.

Then he invaded and attacked white.

White missed a good chance.

If she'd sacrificed one more stone, she would have had a better position.

It was a pity.

The moves I showed you in the previous lesson came up in an online game.

I don't think that's because I taught such moves to you.

However, it's clear that most of the variations we've seen are practical.

If you learn little by little, you'll be able to utilize them in your own games!

Thank you!
