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

What's the most profound Go technique?

There are fascinating things, such as snapback and continuous atari.

But I think 'three liberties in the corner' [the tombstone squeeze] is the greatest Go technique!

One can collapse many liberties down to just three, and capture a group.

So it's possible to reverse a capturing race. It's an exquisite technique.

Many trick plays appear in capturing races.

Today's lesson will touch on this. Let's have a look!

This might be the thing you fear the most about 5-4.

After black's attachment, there's no problem if white hanes on the outside.

But this inward hane is troublesome.

This is one typical trick play.

However, if you know the tombstone squeeze, you can always punish it.

Next, black attached on the other side.

We'll look at the situation after white plays these severe moves.

We've learned about many moves which are played in response to white's knight's move.

This attachment is a common answer.

At this point, this hane is very scary.

If white answers like this, black won't have any problems securing the corner.

It's a simple joseki.

Professional players often play like this, rather than the other move.

After white's tiger's mouth, black plays on this side or responds here.

It's even and the fuseki will be peaceful.

However, amateurs often hane on the inside.

This move may be played hoping that black will make a mistake.

However, there are also josekis derived from this move.

After the cut and push, black hanes and connects.

This is a long, but reasonably common joseki.

And playing like that would be simpler.

Actually, if you can't deal with this inside hane, you shouldn't attach here.

So, if you've never seen this move before, I recommend that you look it up in a joseki book.

We're going to look at potential trick moves, rather than joseki, today.

White may atari and block here.

If you don't know how to deal with it, it will be a problem.

I'll show you a typical mistake.

Black must rescue these cutting stones.

But some players don't know that, and they just atari like this.

And then they attach here, to sacrifice them.

If you really don't know how to answer, this might be a possible choice.

It's better than collapsing completely.

Despite the loss of two stones, some people play like this.

But, because of this first line hane, black still isn't alive, even after this kosumi.

It's a big disadvantage.

This is only better than the worst case scenario.

It isn't a good result for black.

Therefore, black has to save his stones.

Turning here is the only move.

At first sight, it seems like white's group is in trouble.

But after this jump, it becomes flexible.

If black blocks, white connects and this group has many liberties.

So black has to jump out.

Then white will connect or extend here.

Black has to look after his three stones.

After that, white will push and wedge here, to separate black.

Black's in trouble. He can't cut here, nor can he connect.

After white jumps here, defending becomes urgent on both sides.

As I said earlier, you need to know how to reduce white's liberties quickly.

If you block like this, white's liberties will increase greatly.

Black can't win this capturing race.

In this case, there's a famous Go technique called the tombstone squeeze.

With this technique, you can reduce white's liberties considerably.

First of all, you need to push here.

After that, if you block here, white will connect.

White has at least five liberties.

In contrast, black's relatively short of liberties.

It's no good.

In this situation, cutting here is good. You should remember this tesuji.

Because of the shortage of liberties in the corner, white can't atari this way.

So white has to atari here, then this move is essential!

When white ataris these stones, you atari here.

The most important move is this throw in.

White has no choice but to capture the stone.

After that, we should play the double atari first.

When white comes out, this is the point at which some players make a mistake.

They think they can capture white by blocking here.

If white attaches, black connects and ataris.

But it's a mistake.

This throw-in is a tesuji.

If white moves this stone out, black's whole group will be in danger.

So black has to connect here first.

White has to push here, then black can atari and capture white's three stones.

White can't connect here, since she only has three liberties, as I said already.

Black can capture white.

Inevitably white has to push, then black ataris.

If white ataris, black can capture white's stones in sente.

After that, black captures this stone.

It's better for black.

Because black's moyo is thicker than white's.

There's one more thing.

Instead of the atari, white can extend here.

At this point, you have to play carefully.

If black just captures, it's different to the previous variation.

In this case, white can't move her stone out.

Black will push first.

Then he cuts and captures white's six stones.

But if white extends, black mustn't capture these stones.

If black does so, white will move her stone out, and black can't cut here.

It's a huge difference. Black has to crawl along the second line several times.

This is the final trick.

If white extends, just capture this stone.

If white connects, black's stones are captured.

However, black gains sente instead.

In conclusion, it's still better for black.

You have to remember the tombstone squeeze and be wary of the final trick.

Then you can punish white's trick play.

This extension is the last trick move.

If white ataris, capture these stones immediately.

But if white plays here, you have to capture this stone.

Instead of these three stones, this one is much more important.

We've looked at this attachment after white's knight's move.

In this situation, black has another response.

This is more practical and you may well face this variation in your owns games.

As I said, black can also attach here.

Black should choose this move when the ladder is favorable.

Otherwise, white will block here.

Let's suppose the ladder favors white.

In that case, white will extend and black's in trouble.

If black ataris, white can come out.

Black has to block here, then white pushes.

White can't crawl like this. It's out of the question.

So white will cut and push, creating a ladder.

But thanks to the top right corner stone, the ladder favors black now.

So black can capture white by blocking here.

So, when the ladder is favorable, you can attach here to avoid complicated variations.

In a way, this attachment is more plausible in this case.

In addition, it's harder for white to trick black.

If white extends, black pushes here. It's just simple.

If black attaches, white has no choice but the hane.

After these exchanges, black tenukis. It's a joseki.

The corner is quite big. Territory oriented players would love this variation.

Despite the unfavorable ladder, some players still block here.

There's one more thing you should be aware of.

Never exchange this move.

Some players want to capture this stone.

It's a common mistake. Even though black captures white's stones, he'll eventually fail.

Some people are satisfied with the fact that they can capture these stones.

Let me show you how black fails.

White can't rescue her stones.

However, they can still play a role before dying.

When white attaches here, black can't hane.

Because this placement is a wonderful tesuji!

If black connects, white cuts here.

Black has to cut because he can't push here.

But black still can't escape. It's a loose ladder.

The result is a disaster for black.

So black has to play here, then white hanes after forcing with this atari first.

Even though black captures two stones, it's a big failure.

So the tiger's mouth is a bad exchange.

Just cut here with confidence.

Since the ladder is favorable, black can fight.

In spite of that fact, some players hane anyway.

They want to oppress black with their power based game.

If white extends, just connect because the ladder favors black.

In this case, everything regarding the ladder is favorable for black.

After these exchanges, white might extend like this.

You need to know how to deal with this move.

Here's a typical mistake. Some people worry too much about the cutting stone.

If black extends here, white will attach and black's entire corner group will die.

Many players play like this.

And some push here instead, because it's sente.

But white hanes.

Because of the short ladder, black can't cut.

So black has to jump, then white attaches here.

Black can't manage both groups. He's in trouble.

This is no good.

Some players attach like this instead.

How would respond if white cuts here?

It's a famous trick play.

If black ataris, white counter-ataris.

Capturing this stone is inevitable, but then white will separate black.

This black stone becomes useless.

In fact, it's not a big deal.

Don't play atari. Instead, just pinching here is the answer.

White has no time to extend.

It's a ladder.

How about this cut?

If white ataris, don't extend like this.

Interestingly, the ladder doesn't work anymore.

Because white's cutting stone acts as a ladder breaker.

So black can't capture white's stones anymore.

Therefore, capturing this stone is the proper move.

Then black has miai and can capture white's stones on one side or the other.

Therefore, black can attach here.

If you remember this pinch, there's no problem.

However, there are better moves.

This pinch hits the vital point.

If white descends, jump here.

The corner is safe now, and you can aim at this extension.

And there's another possibility.

This jump is also good.

White can capture this stone in a ladder.

But then black can make use of a ladder breaker.

White has to capture, then black can take another big point.

It's simpler and better.

Don't worry too much about this stone.

If you try to rescue it, you'll lose the corner.

In addition, you should respond confidently when white cuts here.

This is what white's hoping for, but you know better.

The best response is to leave that stone and protect the corner.

By exploiting the ladder breaker, you can take many big points anyway.

White can't resist.

Disregarding the cutting stone is the best response to this trick play.

It's time to review an actual game!

This was an online game played between two 6 dans.

Right from the beginning, they played several josekis which aren't quite joseki.

The lead kept changing hands.

Let's investigate how either player could have taken a firm lead.

In response to this pincer, white normally jumps out.

But white attached like this instead.

Players who don't know the joseki tend to play like this.

However, this counter attachment was a big mistake.

Let's see the result.

White's territory overwhelmed black's moyo.

Let's look at their mistakes.

Before approaching, white played here.

The white player may have seen it it pro games.

However, white usually plays there when there's a stone in the bottom right.

Then white can form a good position.

If white doesn't have a stone in the bottom right, this move isn't that effective.

After white's extension, black will approach like this.

This exchange isn't profitable for white.

So white should approach the corner first, then this move makes more sense.

In the actual game, white tenukied after that exchange.

That shows that this exchange was unnecessary.

Anyway, white approached.

When black pincered, it wasn't hard for white to answer.

White should jump twice, like this.

After this pincer, a battle will begin.

This is a joseki.

This would be a normal progression.

But white didn't play like this.

Let's look at the actual game.

White attached here. There's no such a move in joseki books.

The answer is simple.

"When your opponent attaches, hane."

The hane is the best answer.

According to the basic principles of Go, white has to extend.

I guess black was worried about this cut.

I wondered why he didn't hane.

If white cuts, black can atari twice.

Then black's corner is very big.

This is simpler and better than the game.

I don't think he would have worried about this extension.

White's exchanges strengthen black.

If black was concerned about this, it's a misjudgment.

In the actual game, black made a huge mistake.

He attached here. It doesn't make sense.

In response to white's bump, black cut.

After that, this stone was dead.

It's no good.

If he didn't like the hane, there was an alternative.

He should have bumped and blocked like this.

By playing like this, he would've ended up with a better shape.

But he didn't choose this variation.

Eventually, black lost the corner.

Even though black enclosed this area, white cut and took the corner.

This was huge.

Above all, there were too many weaknesses.

Black defended here, and white approached.

If white had cut here instead, black would've been in big trouble.

If black extends, white can harass black's group after exchanging this forcing move.

Black's in trouble.

Black's defense wasn't the best answer.

Connecting here would have been better.

Because of this cutting point, defending elsewhere wasn't good.

But this bad result was due to black's previous mistake.

Black's attachment was very bad.

After white's bump, black had no proper answer.

In response to the attachment, the hane was the answer.

Then white's attachment would be a bad exchange.

Black may have wanted to copy white's attachment.

But you shouldn't play like this.

Even if you don't know how to respond, don't follow your opponent's moves.

That will only lead you to failure.

When you don't understand your opponent's intentions, think about Go proverbs.

There are many helpful proverbs in Go.

You'd have several proverbs in your mind, at least.

If you try to follow them, your moves will receive a mark of at least 80 points!

Aiming for the 100 point move all the time isn't always good.

If you focus on consistently playing good moves, you'll be able to play wonderful games.

Thank you!
