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

This is the last episode of 'Punishing Trick Plays'.

We've looked at the 3-4, 4-4, and 5-4 points.

We've also studied trick plays that appear in handicap games.

There are lots of tricks in Go. I know well over 100 trick moves.

Among them, I selected 50 to 60 useful examples for you.

I advise you to focus on today's lesson and review previous lessons.

If you look over them again, it will help you to become stronger.

Let's look at today's theme.

In response to white's knight's move, black attaches.

Instead of playing the hane, white simply extends.

After black attaches, white wedges.

We'll investigate this move today.

In this case, white attaches here.

When black hanes, white usually cuts on one side or the other.

Instead, she pushes here. We'll examine this move too.

If you watched the last episode, you'll probably remember this.

Because of the top right corner stone, the ladder is unfavorable for white.

So when black attaches, it's hard for white to hane.

Instead, this extension is the proper move.

Pushing here is necessary.

White can't block here now.

Because this cut is very powerful, and black's corner is stable.

So this hane is impossible.

This extension is the proper response.

What if black tenukis and splits here?

In that case, this attachment is severe.

White will bump or extend like this.

It's a nasty forcing exchange for black.

Because of that, black wants to attach here first.

After these exchanges, black tenukis.

This is black's intention.

However, white can try to resist.

How about bumping here?

This cut is conceivable.

White wants black to fall back like this.

But then white's cut becomes profitable.

Let's compare the two variations.

If white pinches now, black will connect like this.

But in the previous variation, it's as if black answered here.

That's a bit unprofitable.

So if white cuts here, black has to connect.

In response to white's hane, black captures this stone.

However, this isn't today's trick play.

This wedge is the move.

How would you respond to this?

Here's the most important thing.

Can black capture this stone?

If black connects here, white will push first.

Then white will capture these two stones.

It's a trade and it's slightly better for white.

Black could play like this though.

Later, this hane is sente and black's shape is fine.

So it may be playable.

Here's another way to play.

Some players choose to capture white's stones like this.

If white cuts, black has to come out.

Some players will be confident because of the ladder.

That's true. The ladder favors black.

Because of this black stone, white can't capture black.

In addition, she has a cutting point here.

White can't extend because black will push and separate white.

Therefore, white has to atari on this side.

After that, she can enclose this area.

Black should answer here, then white can block here too.

This is the best answer when the ladder favors black.

Here's another typical mistake.

Many players atari here.

This is too passive.

If white connects here, many weak points are exposed.

Black can't resolve them with one move.

If black plays a tiger's mouth, white blocks here.

It's a big loss.

Let's analyze this exchange.

After white wedges and connects, black should defend around here.

Because of this move, black can't easily develop his group at the bottom.

Even if black plays a knight's move, white can shut black in with this attachment.

Black has to capture this stone, so this area will be enclosed.

This wedge intends to intimidate black.

So be careful.

Even though it's a bit unprofitable, you need to cut first.

This trade is fine.

And here's another choice.

Since the ladder is favorable, block here and capture these two stones.

As I said, white can't capture this stone.

After that, respond to all of white's forcing moves.

After black captures, it's slow for white to block here in gote.

Because of the cutting point, white has to play this tiger's mouth instead.

Then black gains sente and the corner is very big.

This variation is also alright for black.

But if you get scared and atari like this, you'll lose points.

After white's connection, black can't manage all of his cutting points.

Black has to connect here, but white will cut.

Capturing this stone is inevitable, but white will capture black's two stones.

They're quite big, so white's successful.

The best response is to resist and cut like this.

Don't forget this move!

You have to consider the ladder in your mind.

If the ladder favors white, black has to trade now.

Remember the proper response to white's wedge!

Here are some common continuations for the 5-4 point.

We've looked at this attachment and the knight's move.

This attachment is also possible.

Some people may doubt that there's a trick move in this variation.

There are two josekis.

When white plays here, black can extend or hane.

If black extends, white attaches at 3-3.

After this tiger's mouth, white ataris.

Black has to extend, then white defends her moyo too.

It's an old fashioned joseki.

There's another variation too.

Instead of the tiger's mouth, black can just connect.

This is also joseki.

This hane is played more often.

Most professional players would choose this move.

It was said that there were two josekis here in the past.

Cutting on one side or the other is possible.

But pros rarely cut here.

In order to make shape, black has to capture on whichever side white cuts on.

This is a fundamental principle of Go.

This black group is alive.

In addition, black can play a ladder breaker.

So many players don't like this variation as white.

Therefore, this cut is better.

Black has to capture, then white can take the corner.

After that, black pushes.

It's a popular joseki.

This looks better for white since the corner is big.

However, that's not entirely true because there's still some aji.

After black pushes, white will play a tiger's mouth to expand her moyo.

This the expected sequence.

And here's the aji that I mentioned.

On the surface, white's moyo looks larger than black's.

However, suppose that black plays a stone around here.

Once black extends here, white won't feel like answering.

However, in this case, black could cut here later.

White has to cut here.

At this point, this atari is tesuji.

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

So white has to capture, then black ataris again.

Compared to the original variation, white's moyo becomes a lot smaller.

Furthermore, this group isn't alive.

This is the aji in the corner.

In fact, what makes the aji possible is this push.

Then black can aim at the aji.

Therefore, this push is essential.

After that move, white has to be mindful of the aji.

It's important.

By the way, this isn't today's trick play.

This push is the trick.

Interestingly, those who make a mistake here often don't know how they got into trouble.

Look at this carefully.

Which move comes to you first?

Obviously, you'd think about this extension.

You don't feel like connecting here, because white will apply pressure like this.

It's no good.

If black extends, white will cut here.

Some may follow the proverb 'capture where your opponent cuts'.

But is that proverb applicable in this situation?

Isn't black's shape awkward?

Black's supposed to push here.

But black flattens his own moyo, instead of playing the tiger's mouth.

That's white's aim.

So black has to answer carefully.

He mustn't capture this stone immediately.

Be careful of that.

That's the typical mistake made by black.

Nevertheless, black doesn't have other choices.

This move isn't good, because black has to crawl along the second line.

It's the worst choice.

So when white cuts, you have to connect here.

Of course, white can't push like this.

And he won't push here because that will help black get many points.

In this case, this attachment is a tesuji.

If black captures this stone, white can enclose black. That's the aim.

Since this atari is sente, black should push.

But black's position is flat. It isn't good.

You need to play bravely in this situation.

You have to come out like this.

If white connects, push first.

After white answers, attach here.

Once black makes these exchanges, the corner is safe.

After white's tiger's mouth, this push is necessary.

Because of the cutting point, white can't hane.

Then black can jump here. The result is even.

The intention of the push is to make black's position flat.

Don't forget the proper move when white attaches here.

If you capture this stone, white will enclose black.

All you need is confidence and fighting spirit. Don't forget this!

Now it's time to review an actual game!

Many of the variations we know appeared in this game.

However, the players didn't answer perfectly.

Let's look at their mistakes.

This shoulder hit was an appropriate move.

This jump was the first mistake.

However, black didn't punish it properly.

Black cut on the wrong side.

White could've taken advantage of black's mistake.

Not only was this wedge unnecessary, it also helped black.

Because of that mistake, black took the lead.

Let's examine their mistakes.

White jumped here.

After that, black should play a shoulder hit.

However, many players don't seem to play the proper move.

We used a database analysis tool to look at this position.

By the way, a fan was curious about the analysis tool, so he asked me about it.

He's a Go teacher and he was wondering whether he could purchase this program as a teaching tool.

Unfortunately, it's not for sale.

We looked at 20,000 games by players of various levels.

How would they play in this situation?

First, let's see how Baduk N TV 5-6 dans played.

Which moves would they choose?

The majority of players chose A.

And 12.4% of players played at B.

Next, let's see 7-8 dan's choices.

The percentage of B increases.

62% of players played at A and 22% played B.

Let's look at Baduk N TV 9 dan's choices.

The percentage has practically reversed. More than half chose A, instead of sliding!

Only 22% of 9 dans slid at B.

Let's see pro's choices!

A vast majority of pros played at A.

On the other hand, 18% of players chose B.

It can be seen that answers vary depending on the level of the player.

In the actual game, black pressed here.

In response, white should push.

And this is a natural flow.

It's a basic sequence.

Then black can tenuki and approach here, to pressure white.

Or, this knight's move is also possible.

And there are more choices.

Instead, white jumped here.

Despite white's mistake, black's answer wasn't good.

This push was fair enough.

But this cut was problematic.

Instead, he should have turned here.

If black continued with the knight's move, like this, his position would be wonderful.

Clearly, it's better for black.

But he didn't play like this.

This cut was a strange move.

Capturing this stone was a good choice.

Inevitably, black had to capture this white stone.

After pushing up, white jumped out.

Look at the position. Both sides exchanged a ponnuki.

The exchange of the two ponnukis is even.

But black's two stones became isolated.

As a result, it was bound to be a failure for black.

But then white made a blunder.

It was time to jump here, or at least connect under like this

Then black's group would be floating.

But white wedged here!

Why would she play there?

After this atari, black's group became stronger.

All of white's exchanges here were very bad.

The position had changed.

When black played this knight's move, white had no proper answer.

They exchanged several moves.

This is the actual progression from the game.

Look at white's bottom group. It isn't alive yet.

Black's group wasn't alive yet either, but it was stronger and more stable.

Black should have been in trouble.

But, because of the wedge, the situation was reversed.

They both made mistakes right at the beginning.

Since they didn't punish one another properly, the situation reversed many times.

White's wedge is mysterious.

In the end, black's answers were good, so he took control of the game.

We've looked through handicap and 3-4, 4-4 and 5-4 point trick plays.

There were two themes in each episode.

In total, the number reaches approximately 60.

There are usually a number of complicated variations related to a trick play.

If you've reviewed and understood them, I think you'll have improved by two stones already.

But if you don't completely understand them, it might be worse than not learning anything at all.

So I recommend you that you review this series again.

And I'll see you again in my next series!

This is the end of 'Punishing Trick Plays'!

Thank you!
