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

What was the first joseki you learned?

When I look back, it was the knight's enclosure and then the attachment on top for me.

But even though the knight's enclosure and the attachment on top are easy,

There are many possible trick plays after these answers. Let's have a look at the attachment.

Black attaches on top when white approaches. We call this 'attach and extend joseki'.

The following sequence is common. There's even a rhyme about it.

Attach and hane, hane and extend, tiger mouth's the vital point, block the corner etc...

Normally, white extends along the bottom, but white instead.

We call this an 'obstinate trick play'.

If you don't know how to respond, you'll keep getting trapped. Let's learn about this.

There are several trick plays related to this shape. This is the hardest one to deal with.

How would you respond if white exchanges this hane first and then cuts?

White prevents black from descending to the same point.

White knows that black would descend to the second line.

This one is quite hard for black to punish, so we'll have a look at it.

This is the 'attach and extend joseki'. What do you worry about most with this joseki?

If you don't know how to deal with white's cut, you can't easily play this joseki.

This extension is the most common move for white.

I also learned that this was the right move for white.

When I got stronger, I started to play this knights move, and

When I got even stronger, I started to play this tiger's mouth move.

When I was young and weak, I extended here.

Actually, these moves are all similar, but the shorter ones are better for fighting.

Today you'll learn about this push and cut.

If you know how to play against white's cut here, there's no problem.

But, if you don't know how to answer, it's not easy to figure out.

Normally, white doesn't cut like this immediately, but responding isn't that easy.

It's easy to atari here because you're frightened.

Then white would keep extending, and black's three stones would be in trouble.

If you play like this, black keeps pushing from behind, and

White can dominate the center area. This is no good for black.

Since white rarely plays like this, it's probably an overplay.

How can you punish this overplay? That's what you're going to learn today.

When white cuts here, there's also a cutting point here for black to exploit.

You shouldn't play like this without any plans or thoughts.

If black descends, white can hane here and the capture the corner stones.

White got the corner and black got nothing. Black mustn't play like this.

This move is very important. It's the key point of this trick play.

You can simply descend here.

If white plays the cut, it means white really looks down on black's skill.

White wouldn't expect black to know about this descent. Otherwise, it's hard to cut.

There's no good move for white here. White can't play like this, even if black's a beginner.

Black cuts, and there's nothing white can do. Even a beginner can see that.

So white has to connect here, right?

Now atari, and just answer whatever white wants to do.

White plays diagonal move and it looks like it makes miai. This is important.

Don't be frightened and just descend here. Don't atari, that's a very bad exchange.

Just descend. If you look at a book of trick plays, you'll find this is a basic pattern.

White jumps here, and where should black play next?

This wedge is good. If white ataris, black cuts. Oh, that cut looks nice!

White should connect, then black descends and white's dies in the corner.

But what if white extends here instead of jumping?

Atari here bravely and attach in the corner.

White will never win this battle. Black has three liberties, but white only has two.

Since this doesn't work, white can try another move. The descent.

Don't be afraid. Block here unconditionally.

If white jumps, attach here.

If white hanes, it's an important moment. Play here!

Then white should connect here, otherwise white's cutting stones will die immediately.

Then black descends here. White can't win the capturing race because it's 'one eye vs no eye'.

You must have know this already. Black has an eye, but white doesn't. So white can't compete.

We call this 'one eye vs no eye'. White dies.

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

White can try this move.

In this case, black shouldn't play the moves you've just learned.

You might think that black can still capture white with this wedge, but that's not true.

White can play like this, and it becomes ko fight.

This is a serious problem for black. You shouldn't play like this.

When white blocks on the second line, there's a simple way to respond.

Cut here first. White has to atari under.

Extend twice, white has to answer.

Black's next move's important. Where should black play now?

Atari here now, and play the same as in the previous variation.

Play exactly the same moves as before.

Still the same. "Huh? He said it was ko fight before?"

Kim Seongryong 9p said it was ko, right, so it's going to be a ko fight.

Atari, take, and wow! There's a ko threat!

White answers, and black takes the ko back. Now white doesn't have a threat.

It's still the opening, so usually there won't be any big ko threats.

So in this case, the only move you should know is this descent to the second line.

What do you think about this 'attach and extend joseki'? It's a common joseki for beginners.

But, there are still possible trick plays. Nobody teaches you about those.

I'm assuming you know the normal joseki, so I'm teaching you to deal with the tricks.

If you don't know about the hidden trick plays, you can't say you've mastered it.

You've learned about the 'attach and extend' joseki and a trick play related to it.

Trick plays.

BANG!

You just learned how to deal with white's push and cut, but what if white hanes here first?

I'd understand if there was already another white stone at the bottom.

But white obstinately hanes and then cuts here to fight.

Let's see black's common mistake first.

Normally black knows this atari won't work well, because there's an obvious cutting point.

Black's corner's in trouble, so you can see that it's not a good way to play.

If black ataris under, as I showed before, it's favorable for white too.

Because black's three stones become weaker, and white's hane isn't that bad an exchange.

Which means, white got a satisfactory result without playing any bad exchanges.

You learned that white's cut doesn't work because of this descent.

But, in this case, this atari doesn't work anymore.

So what should black do now? There's a solution.

When there aren't any white stones at the bottom, this is surely an overplay.

But, if you want to punish it, you need to know how to do that.

There are two important points. If you know both, you'll succeed, otherwise, you're trapped.

So, white can't easily try this, because it's a 50/50 chance.

However, when white plays like this, he expects that black doesn't know how to respond.

So white may think that it's not 50/50, and try to trick black.

Look carefully. You'll get a good result if you cut here.

This atari doesn't work for white, as you can see.

This connection doesn't work either. This atari is a good answer for black.

If white extends here, black descends and white's five stones are captured.

If white ataris, black takes the stone, and the result's good for black.

Capturing black's single stone wasn't white's plan.

This result is good for black, as I just said.

But, if black just descends without exchanging the atari, it will be troublesome.

White can cut and capture black's corner stone. This is no good for black.

You should be careful to atari here first. Don't forget about it.

So, white would atari here first, and it's important for black to extend once.

If white connects, black ataris and blocks on the second line. White can't live inside.

Since white can't live inside, white shouldn't play like this.

You should know that white has to push under, and now...

Black should cut and capture the single stone.

White can't play elsewhere, white has to atari here.

If white extends on the left, black would extend here and white has answer.

Extend some more, and when you think it's time to go back...

Play here to save the corner. The lower side and the left side are miai, so white's in trouble.

Therefore, white has to atari here to avoid the previous variation.

You should know that those ataried stones aren't important now.

Capture this cutting stone instead. Atari and block.

Capturing these two stones is very big, and black's corner has no problems.

If white captures two black stones, black should capture too.

Even though white captured two stones, black's shape is far better than white's.

So in conclusion, black should cut first and then capture white's hane stone.

Black should extend first and capture the stone on the second line.

After capturing here, black has miai. A and B.

Let me show you a mistake which black can easily make.

Black cuts here because black thinks it's similar to the other variation.

This cut is a big mistake. If white ataris, it's more or less the same.

Black still has miai on the left and at the bottom.

But, the problem is that white won't atari when black cuts.

White will just connect and you can see the difference now.

If black still ataris and blocks, white can cut here now.

White can atari here in sente and then hane on the second line.

Now white's cut or hane in the corner are miai, so black's in deep trouble.

So, this is the main thing you should watch out for.

When white cuts, black should cut here first. The followups are easy.

If you cut first, you'll never get tricked.

If white connects, just atari. This is so easy, right?

If white ataris under, extend and then cut here, like Kim Seongryong said.

Don't try to extend further, just cut.

After black takes white's stone, black has miai.

However, black can easily make a mistake. Cutting here now is that mistake.

After that white connects, and black would have to atari under.

As I showed you at the beginning, that's the worst case scenario for black.

Black's three stones become lonely, and black has to keep crawling.

What do you think about the 'attach and extend' joseki?

It's one of the most familiar josekis for beginners.

Anyone could play this, even 18 kyu players.

But, there are some hidden trick plays with that are somewhat difficult.

After you master those trick plays, then you can say you know this joseki well.

There are many types of trick plays. There are a small number of trick plays in basic josekis.

But, there many trick plays related to complicated josekis.

Trick plays!

BANG!

It's time to review a game.

This was a game between two 8d players on Baduk N TV server.

Since they're 8d, it was a high quality game.

However, in the opening, their play wasn't perfect after an unusual move.

Let's have a look at the scene.

The top right joseki is well known. Let's look at the lower left corner.

Black pincered in the same way, and they were headed for the same result.

But then black haned from behind, and white answered.

After that, white jumped and black attached on top.

White wedged and connected, and then jumped along the third line.

So far, it looks as if white was tricked while under time pressure.

Was black's move a trick play or a good move?

White's answer wasn't good enough anyway. Let's have a look.

Black could follow the same pattern as in the top right.

There wasn't any reason for black to not play that joseki, but he deviated anyway.

This is a basic joseki, but let's analyze this pattern using a database.

Let's see 5d's and 6d's next moves.

5d' and 6d's moves, based on 20,000 games.

A is at 72% and B is 20%. That's quite a bit higher than I expected!

C and D were also played.

A is the normal joseki, and it was played 72% of the time, while B was played 20% of the time.

Let's have a look at 7d's and 8d's choices. This game was played by two 8d.

As you can see, the percentage who chose the joseki move is higher; at 82%.

B is at 15%. It's quite small compared to the 5d and 6d.

Let's see 9d's choices.

Almost all moves are at A. 95% of the time. All I can say is that higher dan players know josekis better.

B is only at 4%.

Let's have a look at pros' choices.

A is at 99%, they've only played B in special cases I imagine.

Black played the second most popular move, this hane.

In the actual game, white answered in the corner and jumped here.

But white already made a mistake. What do you think it was?

If black hanes, you should think about the surroundings and the situation.

There aren't any stones at the bottom now so, in this case, white can play boldly.

White shouldn't just answer in the corner habitually. White should extend here.

Then there's no special move for black now.

If black attaches on top, now hane and the extend at the bottom. This is far better than in the game.

If black extends the corner with fighting spirit,

White can push up and take a vital point in black's shape.

If black attaches here, white can hane, and black's in trouble.

If black cuts, white can atari, and black's still in trouble.

Black can't play this empty triangle. White moves the single stone out and black's floating.

So, if white extends, black should push from behind like this.

Then hane and extend.

Black should connect, to make good shape, and then white goes back to the corner.

And then white extends along the bottom. Look at this! Who's territory is bigger, black's or white's?

White's position is ideal, but black's isn't that good.

But, white answered in the corner first, so he couldn't get a good result like this.

Here... white habitually answered in the corner.

After the exchange in the corner, it's not as good to extend as before.

If white extends now, black can pincer and fight like this.

So white jumped here and, when black attached, white made another mistake.

If white had played well now, the result should have still been playable for white.

This wedge was a mistake, and because of this, white got a bad result.

Black was able to make good shape with this extension, and the tiger's mouth made it even better.

Then where should have white played instead?

How should white answer this attachment? Think about the Go proverb.

Hane against the attachment. Hane here!

Black would extend, and then white just connects here.

Black has to reinforce somehow, and it looks as if white exchanged this in the game. What a bad exchange!

There's no reason to push. If white just extends here, it should still be playable for white.

But in the game, white played here and made black's outside wonderful.

It's easy to make mistakes in simple situations.

But if you follow the proverbs, you'll be able to play better.

Answering habitually was white's problem in this game.

There are gaps between 5-6d, 7-8d and 9d amateur players.

That can't be helped, because their strength and levels are all different.

However, if you can answer correctly, it doesn't matter what rank you are.

You can turn your opponents' trick plays or aggressive moves into overplays.

You can learn step by step, by watching this series of lessons with me.

How did you like today's lesson? I'll see you next time.

Trick plays!

BANG!

Thank you!
