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

Last week, I visited a Go club in Gangnam.

A Go player asked me about some recent patterns.

I felt that Go players' levels were increasing.

I showed some variations to him, and realized that they'd make good material for this episode.

Let's have a look.

This is from white's two space high pincer, with the 3-4 point.

At this point, this attachment may look unfamiliar.

It's been popular since the 1990s. It's said that Cho Chikun 9p invented this move.

Here's a related shape.

At some point, you may face white's bump and cut.

This is the hardest response to deal with and it's very complicated. We'll look at this too.

When white pincers like this, this large knight's move is the most common response.

White normally attaches here next.

Up to here, it's a common progression.

However, there's an interesting move for black.

Instead of the bump, black can also attach like this.

Frankly, it's not a trick play.

It's been played since the 90s.

If either player answers improperly, they'll find themselves in trouble.

Because of the complexity of this shape, many players simply bump here.

However, people started playing here, because it creates some other options later.

It's useful especially for those who are fond of territory.

So, many pros play this move.

After that, white has to answer properly.

Otherwise, he'll be in big trouble.

If white answers here, black will bump, push, and cut.

White will be in trouble from the beginning.

Therefore, you shouldn't hane here.

This jump is the best answer.

This cut isn't good.

When black pushes and cuts, white has no counter.

Because of the ladder, white's in trouble.

Therefore, white has to jump.

Let me explain again. First, don't hane here.

And this cut is another mistake.

If black bumps, white has no proper answer, so be careful.

What does this jump mean?

This hane is the only answer and black must respond carefully here.

When white cuts, black has to be patient.

This atari is a mistake. It leaves a cutting point here.

After the atari, black still needs to defend his weakness.

Black can't tenuki.

If white cuts here, black will be in trouble.

So black has to connect here, then white will extend.

Now these stones are isolated.

Let's go back to the previous variation.

At this point, black mustn't atari like this.

Instead, this extension is a proper response.

If white blocks here, black can atari, deforming white's shape.

Inevitably, white has to play an empty triangle.

In addition, this stone can be captured later.

In contrast, black can hane and increase his territory.

So white has to block here instead.

After this atari, black captures this stone.

White mustn't move out like this.

If black blocks here, white's stones die.

So you should be careful.

White has to sacrifice with this counter-atari.

When black captures the stone, white encloses.

After that, black extends here.

Subsequently, white ataris or descends.

Capturing this black stone won't affect the life of black's group.

So it's even.

In conclusion, black gains territory, while white builds influence on the outside.

Black deals with this area in sente.

If you're white and don't like this, there's another move.

This extension is the move.

It looks a bit loose, but there's an advantage.

If black tenukis, white can rescue this stone.

Black shouldn't atari like this.

If white ataris, it's a ladder.

[Tr: The ladder favors black here, but white can still squeeze with a net and be satisfied.]

Inevitably, black has to atari and sacrifice his stones.

To start with, white captures these stones.

After that, she can capture another stone in sente, reducing the corner.

Therefore, black needs to answer immediately.

He should push and play an empty triangle, then enclose this corner.

It's even for both sides.

White has another option.

The intention behind black's attachment is to take territory in the corner.

When black hanes, white has another move.

It's this counter-hane and you should be careful of this.

Black shouldn't capture this stone right away.

This atari is what white wants.

White will cut and extend here, taking the corner.

Even though black captured, the placement of this white stone is so good.

Because of that, black's group is still unstable.

Since white's safe, this group will be attacked.

You have to avoid this variation.

Let's investigate the right response.

This atari isn't good. There's no answer after this move.

Therefore, this cut is fair enough.

At this point, black shouldn't atari here.

Connecting here is the answer.

Then white plays a knight's move.

If black plays here, white will connect, then there's no answer.

So this atari is correct, then black can tenuki.

White encloses black and it's a good compromise for both sides.

White can extend here in sente later.

This is regarded as joseki.

When black attaches at 3-3, there are two choices for white.

However, both variations are quite long and complicated.

So you need to learn these sequences and understand both variations.

After that, you can attach at 3-3 freely and deal with your opponent's responses.

In this joseki, there are many useful moves which can be applied to other josekis.

So don't forget it!

White has another tricky move.

If you don't know it, you can't use this joseki properly.

Up to here, it's the same.

There's a move which can be scary for some players.

Many don't attach at 3-3 because they're worried about this bump.

When playing here, you should know the proper answer to this.

Since many complicated variations are hidden, you might find it hard to understand.

But once you do, you can attach at 3-3 without hesitation!

In response to the bump, you have to block here, of course.

If black falls back, the stone at 3-3 will become useless.

Therefore, this is the only move.

In this case, this cut isn't scary at all.

That's because you can easily increase black's liberties with the hane.

So white can't expect a good result here.

When black connects, white has no proper answer.

If she plays a tiger's mouth, there's still a cutting point here.

If white connects like this, the shape doesn't look very nice.

In addition, black can easily shut white's group in.

Even if white cuts, she can't capture black.

Since white has only three liberties, this group is dead.

Therefore, white's fails.

So white has to choose the other cut.

This cut is more complicated.

Black has to connect, then white can atari here.

If you don't know how to deal with this, you can't attach at 3-3.

Because black can cut, or hane here, white's other moves are easy to answer.

This is a good combination.

Black creates miai between the ladder and the bottom group, so white's in trouble.

However, white has another move.

This atari is the best answer for white.

We need to know about this.

This cut is a typical mistake.

A majority of players fail because of this move.

White mustn't attempt to rescue her stones like this.

When black connects here, she can't save her group.

So white will atari instead.

After that, coming out is a good move.

If white ataris again, it'll be fine for black.

Because black can hane here in sente, which is big.

But this is a nice move. Then black's in trouble.

If black captures like this, white will attach here.

This area is completely enclosed.

In addition, white takes sente, so it's incomparable to the previous variation.

That's white's intention.

Black should avoid this.

So how about connecting like this instead?

White will cut and get an iron wall on the outside.

This kosumi is the best answer locally, but white's still better.

She can get a good position like this.

So this isn't successful for black either.

Because of that, black shouldn't cut right away.

Remember to hane in this case.

If white blocks like this, this cut is powerful now.

If white ataris, black can capture these stones in sente now.

Because of this stone, white took gote.

That's a problem.

This isn't good for white at all.

So this jump can be considered.

Black doesn't need to cut and capture these two stones.

I said earlier that this was good for black, but there's no need to settle this area immediately.

If white plays here, she'll suffer more when black cuts.

Therefore, the jump isn't a proper answer.

White has to block here anyway.

In response, black has to cut.

It's a crucial moment when black connects here.

If white jumps, black can move his stone out later.

So white will be in trouble after black connects here.

Therefore, white needs to capture this stone.

This jump is an important move.

Then white hanes here.

Instead of connecting, this extension is the proper move in this case.

If black plays like this, white will block and this black group has few liberties.

So this extension is better.

That's because black can live when white blocks.

Black can take advantage of this move.

With the extension, this group is alive. Don't forget this.

Because of that, black has to play at the 2-1 point.

After that, white captures.

If black tries to capture white's group, white can still make a seki.

In that case, white's influence is much better than black's.

Therefore, black needs to increase his eye space instead.

Black has two choices. The first one is this knight's move.

Or, he can also jump like this.

In spite of the weakness, black can play like this.

This group is alive, which means white has no time to capture this stone.

She has to rescue her own group.

This bump is the correct move.

Because of the cutting point, black can't capture this group.

After white connects, white has miai to cut.

So black has to kosumi.

Before living, this attachment is profitable.

After that, black needs to defend his cutting point.

Instead of connecting, this kosumi is more efficient.

Black's previous jump removes white's eye shape.

So black can aim to attack this group later.

Since white can connect, black's position at the bottom isn't ideal.

But white's shape isn't very good either.

Therefore, it's even and this variation has been played quite often.

White's bump and cut may be scary.

The hane and cut are the key combination.

If you remember that, you won't get into trouble here.

Although it's a bit hard, you can understand a complicated joseki if you take the time.

That's the end of our study of the 3-3 attachment.

Now it's time to review an actual game!

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

There was a peculiar variation in the fuseki.

It's rarely played in actual games.

Their answers were clumsy.

I think that's because the variation is quite unusual. Let's have a look.

It looks like a pattern that's based on the 5-4 point.

So just imagine that this was transposed from the 5-4 point.

Black jumps and attaches and it usually doesn't work.

However, white's answer was wrong.

Why did white just extend here?

Because of this move, white failed.

What's the answer?

Let's investigate this shape.

White played a high approach.

Let's look at the shape more closely.

White already has many stones on the bottom side.

Therefore, it's different from other approaches.

It looks like black has approached white's 5-4 stone.

Because white's stone on the left is pincering black.

So the position was reversed.

However, black's next answer wasn't appropriate.

So it didn't end up as a joseki.

Let's investigate this shape.

How would other players play in this situation?

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

Let's see how players of their level tend to respond in this sort of situation.

38% of players chose A.

And a quarter of the players played at B.

Where did Baduk N TV 9 dans play at this point?

More players chose A.

28% of 9 dan players answered at B.

In the actual game, the black player chose the 9 dan's move.

However, this attachment is the proper move in this case.

After this exchange, black jumps.

Then black pushes and hanes here.

After that, black encloses the corner. It's better than usual in this case.

Because black has greatly reduced the bottom side.

And black's also secured 15 points in the corner.

So it's good enough for black.

It's playable for white too.

So it's even.

But black didn't play like this. Let's see the actual progression.

Without making the the attachment, he jumped here first.

This is usually played when white has no wall at the bottom.

In that case, white blocks from above.

Black pushes twice, then tenukis.

But look at this situation.

White lost potential, as well as sente.

So white can't choose this variation.

He needs another move.

Of course, blocking here is the answer.

Normally, this move isn't played.

That's because black pushes and cuts. Then white's separated.

However, it's different in this case.

Thanks to the wall on the left, white can easily fight.

Normally, you shouldn't answer like this.

But it's possible now because the placement of white's stones is good.

At this point, black played a severe move.

It was an overplay. He should've attached here instead.

But he didn't follow this variation.

This move was rather bold.

The black player wanted white to hane like this.

Of course, this variation is very good for black.

Black splits white and moves out into the center.

However, white can hane on the inside.

Therefore, this fight was supposed to be unfavorable for black.

If white ataried at this point, she would've taken control of the battle.

But she made a huge mistake here.

Due to the extension, white's stone was captured.

She couldn't enclose this area, nor attack black.

The extension was a blunder.

It'd be much better if white had ataried.

Black can't cut here.

If white kosumis, the corner will be captured.

So black wouldn't play like this.

To minimize the damage, he'd atari and compromise.

In this case, the ponnuki is very good.

So it's better for white.

Black can alleviate the damage like this.

But white will take the lead from here.

This extension was clearly a mistake.

Don't forget to atari in this situation!

As for black, he should've assessed the position more carefully.

With this attachment, black can secure the corner.

We've examined mistakes made by both players.

After a tenuki, the relationship between 3-4 and 5-4, 3-5 and 3-4, can be inverted.

Therefore, complicated variations co-exist.

Once you understand the 3-4 point, you'll find it easier to understand the 5-4 and 3-5 points too.

Basically, they're all similar, so you should seek to understand the variations related to the 3-4 point first.

Thank you!
