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

We've been studying four stone handicap trick plays.

But, they're not only for handicap games.

We're actually learning about star point trick plays.

After you master the star points, you'll learn about the 3-4, 4-5 and 3-5 point trick plays.

Let's have a look at today's topic.

When white approaches the corner, answering with this jump is also common.

White's knight's approach on the right side is also pretty common.

This is a typical bullying move by white.

So far so good. There are no problems for black.

When white peeps here, black should answer carefully.

Whether or not white's successful here depends on how black answers now.

After that we'll discuss white playing the diagonal move instead of the peep.

This sort of gentle trick move is rather difficult for black to answer.

You need to know how to deal with this move.

If you don't answer properly, black will end up with a painful result.

What's the best answer for black?

That's today's second topic.

White peeps here. It doesn't look easy for black to answer correctly.

This is a sort of trick play.

So if you don't know how to answer this, it wouldn't be easy for you to jump here.

I assume that you already know about this jump?

When white peeps here, where would you respond?

There's a hidden trick move here.

What if black simply connects here?

You'd be afraid of white's push here.

If black extends, white would connects and it's good for white.

Because white's lower side becomes a big, ideal position.

This is the sort of result black doesn't want when white peeps.

I'll show you a better option for black.

This is easy. Let's study the easy way first.

First, black should poke here.

Black shouldn't extend first. Look at this sequence carefully.

Atari here, and it's a kind of trade.

Black shouldn't connect above, because white's cut is severe.

So, black would connect here, and

When white cuts here, black cuts the left side stone, without playing atari.

White's lower side is big, but black's left side is big as well.

It's an easy way for black to play.

However, this isn't the best way for black. Black shouldn't let white off this easily.

Here's the worst case scenario; black connects here to save the center stone.

It looks like this connection is more urgent.

As we saw, this is a safe way of playing. For beginners, connecting here is good enough.

In this case, pushing through and cutting isn't what white's aiming at.

This fight isn't very promising for white.

After black connects here, there are no good followups for white,

because this atari is sente for black.

Black's good either way.

This certainly isn't white's plan though.

White would enter at 3-3. White's trap lies here.

Black shouldn't block this way, because the black group would lose its base.

Black has to block here, and you'll soon see white's evil plan.

White pushes here and black has to answer. Black must not let white penetrate here.

White cuts here quietly when black blocks.

How can you capture white's two stones? This isn't a tesuji lesson.

This lesson is 'Punishing Trick Plays'. This net works, but white already knew that.

White expects black to know this simple tesuji.

White quietly ataris here first.

And hanes here. If black doesn't answer, white can capture.

There're two ways for black to capture.

If black ataris here, white will connect under here.

How many stones has black spent to capture two stones?


It's an over concentrated shape.

This atari is sente, so white can also develop the lower side later.

This is the worst case scenario for black.

If black ataris here, white will hane. Now it's hard for black to answer.

If black answers here, white will extend.

While black's capturing white's two stones, white builds a huge territory at the bottom.

This is what white wants to see.

I showed a simple and good answer for black before.

If you like the easy and safe way, connect here when white peeps.

As I already said, this is one of the best ways for black.

Though it's not the best, it's good enough for black.

Let's try to find a better way.

When white peeps here, let's look at this push.

This is worth considering, right?

If white blocks, black can cut and it's a net. White can't play like that.

Then where should white play when black pushes? White could extend here.

This is an important moment. If white extends again, where'd you go next?

This connection is good. White doesn't gain any points like this.

If white plays here, black will play at the bottom. This trade is good enough for black.

This is the best way for black.

If white blocks, cut above

When white saves these two stones, black can play like this.

And white's three stones are in danger.

Therefore, the push is the best response for black. It's easier than it looks.

If you can push here, you won't be tricked by the peep.

This connection is an easier way.

But if you want to play more actively, push here.

You should look for opportunities to counter-attack.

If you're careful not to connect here,

you'll be able to punish white's trick play.

We punished a trick play.


This diagonal move can be distressing.

If white peeps here, you'll recall the good answer, because you're in an urgent situation.

But, if white presses black stealthily like this,

you might have difficulty finding a good answer.

And perhaps you'd become nervous and anxious.

You must know what white's aiming for, but it's still hard to answer well.

You'd be embarrassed to play like this.

If you can make double tiger's mouth naturally, that's good.

But, if you make this shape by yourself, it's bad.

You can't do anything with this shape.

If white slides here, black can only answer foolishly like this.

You should play Go, not 'five in a row'.

When beginners learn Go, they play like it's 'five in a row'.

And they also play 'line Go', 'diagonal Go' and 'tiger's mouth Go'.

Since you're becoming stronger, you should try to avoid this sort of shape. It's inefficient.

"Oh, then should I play here instead?"

I already told you about 'line Go'.

Don't play 'line Go' like this.

If you make this sort of shape naturally, that's fine, but don't make it by yourself!

"Shall I play here then?" This is far better than the 'double tiger's mouth'.

This move is tolerable.

"Can I try this one?" This protects black's weaknesses a little more.

But, in this case, white can peep here and when black blocks,

white peeps here again and makes miai. A and B. Black is in trouble.

If black connects, white would play this diagonal move.

Since white steals black's base, it can't be good for black.

These are all bad move. All the moves so far aren't good enough answers.

"Then which move's good?"

There's only one move here.

You must learn the only move today.

But this good move is kind of hard to learn.

Because white played this diagonal move subtly, black should answer subtly (quietly) too.

This is the vital point in this sort of shape.

Which means, this attachment is also possible, but taking the corner is more important.

This attachment is also possible. It's similar.

But in this case, this corner attachment it better.

White's trick play's here now.

White would hane here quietly.

Black would be happy to atari if white clamps here.

But, white would hane here instead. Let me show you the meaning of this hane.

This peep is the most scary move for black. If white peeps now,

black can fight like this, because black's diagonal move can help out.

If white tries to escape, black will play as follows.

Black made white's shape heavy and bad. We call it a 'bunch of grapes'.

And white would feel terrible about this unpleasant shape.

And then black cuts here. Black's good, because black's outside is thick and nice!

As you just saw, white's peep doesn't work very well.

It's because black's attachment was good.

Since that peep doesn't work, white will set another trap.

And this is the trap. White wants black to answer here.

Then atari and extend. This makes miai of cutting at A or B.

You shouldn't get caught in that trap.

You should wedge here when white hanes.

Don't worry about white's atari. There are so many weaknesses for white here.

White should make a double tiger's mouth, then black ataris and hanes in the center.

What's important now? Where's the urgent place to play?

You want to apply pressure to the white group and move into the center at the same time.

Here's the move. This result is good for black.

White needs to look after his left side group now.

Are you worried about white's atari above?

Just connect. It's fairly simple. White still has to connect below.

Then black cuts here, and then goes back to the corner. Nothing to worry about.

If white peeps here, atari in sente, and then block from the side.

White can't cut here, because black can atari under and capture white.

There's one more thing. There's another option for white.

It's the last part to master to deal with white's trick plays for today.

White can slide here without making any exchanges.

You'll be trapped if you just answer here.

There's something white can do now. White hanes here, and

Ataris and extends. It creates miai of A and B again.

Black shouldn't play like that.

As I already mentioned, this angle wedge is the best response.

If white just connects, black can jump now.

If white peeps, black can descend here and white can't save the stone.

The principle's about the same as white's 3-3 invasion.

If white enters at 3-3 directly, where'd you answer?

The principle's the same. Hane and atari in sente, and

Block off the corner. Black can capture the corner stone, and black's happy now.

White's group on the left side is floating now.

The purpose of playing on the left side was to attack the lower left corner.

But, it's a failure for white, because black's safe with 10 points of territory.

White would feel disconcerted if black lived like this.

We learned about two moves today. The peep and the diagonal move.

You should remember those variations if you don't want to be caught in a trap.

Try to understand and remember both situations.

The second one is very hard. Please review and study it by yourself so you can understand it.

Let's punish the trick plays!


It's time for a game review.

This game was played between two 5 dans on the 'Baduk N TV' server.

Let's see what problems they had and what they worried about.

So far so good for both, but white answered here instead of connecting.

Lee Changho also played like this sometimes. It's a very unusual move though.

The problem is this push. Why did white push here? It's problematic.

Don't push from behind unless it's necessary.

It related to white's second line answer anyway.

White played the knight's move now, and it looks like white's play was a bit clumsy.

Black extended at the bottom, and it's not that bad.

White pincered right away, to punish black's long extension.

I don't know why black played like this now. It looks like an overplay for black.

White's answers were excellent. Black's in trouble after white cuts here.

After this the game became bad for black.

Both players made mistakes,

but black made the last mistake, and white got the better result.

Let's look at the game in detail.

White answered underneath instead of connecting.

Lee Changho sometimes plays this move.

When white wants to save some extra points in the endgame, white can try this.

Connecting instead is normal, but let's study this move.

We searched a database of 20,000 of pro games. Let's see how pros answer.

How many will connect or answer underneath like white did in the game?

Let's see pros' choices in their actual games.

Most pros played at A, but as you can see, 0.6% played B.

It's really rare, but it's sometimes played anyway.

Lee Changho's games must be included in the 0.6%.

This game's played between 5d players. Let's see 5 and 6 dan players' choices.

For 5 and 6 dan, B is at 18%. It's quite high compared to pros.

Many amateur players play at B, and white played at B in this game as well.

Let's go back to the actual game.

I don't understand why white pushes here.

This is kind of a thank you move. This push helps black.

White should play the knight's move here.

White can take sente if black answers here.

But black doesn't need to answer in the game, because of white's push.

Since black can tenuki, the game becomes bad for white.

Black plays here to limit white's influence, but it was greedy.

What do you think about this knight's enclosure? Doesn't it look appropriate?

If you think it's too tight, how about this large knight's move?

Those should be the proper moves, but black was greedy.

Even if black extends closely, white won't want to extend after that.

White would be dissatisfied with this short extension, don't you think?

This should be just right for black, but in the game, black extended too far.

What should white do now? Get angry! White played well in the game.

This pincer was good, and black made a big mistake here.

The game's still alright for black, because of white's early mistake.

Where should black play when white pincers here?

Jump! Just jump. Black's erasing white's influence by jumping into the center.

But in the game, black made an overplay.

Black played here to fight. It's the beginning of black's overplay.

Black's hane here is another overplay. The position isn't good for black to fight.

White cuts and black should save the single stone at the bottom.

When white cuts here, there was a far better option for black.

Black should give his stones away and develop the lower right.

The game's still pretty even after black sacrifices his stones.

Actually, the game's already better for white, but it's a long game.

"Compromise is not in my dictionary!"

Black played very aggressively now.

Let's see the actual game. When white cut here, black even ataried here.

When white cut and ataried, there was nothing black could do.

If black connects here, white can hane and capture them.

The two stones are too important to abandon now.

Black ruined the whole game here.

There were several mistakes by both, but they could have played better.

Let's have a look white's mistake again.

If white plays normally, this sente endgame will be guaranteed later.

So, if white doesn't want black to play there in sente, white can answer underneath.

That's the reason why white answers underneath instead of connection.

So you should know that the purpose of this connection underneath is endgame.

Pros occasionally play like this too, to save some points in the endgame.

But you don't need to think about endgame in the opening. You'd better play solidly.

That's why normally the simple connection is better.

When black jumps. Pushing from behind is very bad for white.

The knight's move is better. If black doesn't answer, this attachment is a good followup.

Let's go back to the actual game.

When white plays the knight's move now,

this extension at the bottom was an overplay. Don't be greedy!

Knight's move. Pros might have played here.

Since you're an amateur player, this large knight's move,

is excellent to limit white's influence.

This is too close to white's thickness. When you're running away, jumping into the center's best.

If black played like this after jumping, it would have been far better than in the game.

This would have been still playable for black, if black jumped first.

Black's careless fighting without any compromises led to a bad result in this opening.

You'd better make yourself safe, and then attack your opponent.

Because of that, there's a saying, 'Attack after defending your stones'. It's a Go proverb.

What are you more afraid of? An aggressive move or a subtle move?

The stronger you become, the more difficult it is to answer subtle moves.

A good move is not too aggressive, nor too slack. But, it still pressures the opponent.

So, you should learn how to play those sorts of gentle moves, rather than trick plays.

Trick plays are good to know about, but don't learn them to trick your opponents.

Don't watch my lessons if you want to learn to trick your innocent opponents!

You're watching my lessons so you can defend yourself against trick plays!

See you next time! Trick plays.


Thank you!
