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

We've been studying four stone handicap games, but we're going to look at a six stone game today.

There are two three star formations (sanrensei) in six stone handicap games.

Let's look at some trick plays related to sanrensei.

There are many trick plays for the sanrensei. We're going to study them one by one.

Ok, let's have a look at today's topics.

White played here and there to make the game messy.

Now white invades here, but why on the fourth line?

There's a reason. This is one of the most well known trick plays.

If black attaches under, to connect,

This attachment is annoying for black. How should black answer here?

And what's white's hidden trick?.

Here's the next topic. White jumps in here, and where should black answer?

If white invades on the third line, black can attach on top, but it's not so easy to answer now.

If you don't know how to play against this invasion, you can't play the sanrensei in your games.

There are more black stones on the board.

What if you only look at the left half of the board? Then it's the same as an even game.

So, even if it's a six stone handicap game, just look at the left half of the board.

If look at the whole board, it's a six stone handicap game though.

This lower invasion is more common, right?

If black attaches on top, white can connect under like this.

White reduces black's side, and locally the result is good.

If you only look at the left side, the result is playable for white.

This result is reasonable for both players in even games.

But, look at the whole board now. Do you see the difference?

White shouldn't make black solid and strong on the outside. It's too easy for black.

White can't win by playing like this in a six stone handicap game.

That's why white plays here, to lead black into temptation.

The shape is about the same. If white invades here, black would like to attach here.

If white invades here, black really wants to attach and connect under somehow.

Black simply wants to connect and save the side stone.

White wants to exploit black's psychology.

Playing like this is bad for white. White would never play like this normally.

Black takes territory on the side, but white gains little.

When white plays here, and 80~90% of players would just answer here.

Because black shouldn't let white come out here.

White hanes here after the exchange.

Black's original plan was to cut here now and, if there isn't any exchange,

There's usually no special move for white.

If white attaches here now, black just answers, and there's nothing white can do.

But, it's different after this exchange.

White ataris, cuts, and pushes through.

Black should atari here to connect, and white answers.

White's already created two cutting points, and there's bad aji in black's area now.

Let's continue by looking at the atari in either direction.

Let's see this corner atari first.

White ataris here, and then saves her ataried stone in the corner.

Black can't capture with a ladder, because then white can capture four stones like this.

So, black should atari on the second line.

White throws in, and then extends from atari again.

Black has to push here in order to save his side stones.

White answers, and black comes back to the left side to capture white's two stones.

Then, this atari and hane in the corner are sente for white.

Even if black captures white's three stones, White jumps here.

The corner becomes white's territory, and the result is good for white.

Let's try some other variations over here. The position is the same as the one in the lower left corner.

White invades and attaches in the corner.

If black blocks, white hanes and ataris to complete the trap.

Why is the result bad for black? What did I do wrong? It's not easy to know.

If you don't know what was wrong, you can't play better next time.

It could be even worse for black than the result in the lower left corner.

It's still the same sequence as in the lower left corner.

Up to here, it's exactly the same.

If black ataris here instead, black would get even worse and it'll be miserable.

Let's continue.

This sequence follows a single path.

Black has to push again, right?

White doesn't need to exchange any other moves and can play in the corner.

Then black ataris, but the ladder doesn't work for black.

Black ataris again and white extends. It's not easy to move black's two stones in the center out.

And the result is terrible for black. The game's practically finished now.

It's a miracle that black lost the value of a six stone handicap in the opening!

There's a good way of playing, even if you don't know exactly what black's mistake was.

It's important to think, and try to guess what's white's intention is.

If you don't want to fall into a trap, kick here. Don't worry about the invasion.

White would extend and black jumps to the center, rather than attaching under.

Pretend not to care about white's invasion stone.

It's easy to move out after a high invasion, but it's not easy to attack black's right side stone.

If white jumps out, you can jump out too. Don't worry about the right side.

When white extends here, which is urgent, you can come back and jump here.

However, if you attach on the right, black's already fallen into a trap.

80~90% of players can't get out of the trap as black after this.

That's because there's no particularly good answer for black when white attaches here.

Some books say that black should connect here to reduce the damage.

But, black's stone on the right side's isolated, so it's already bad for black.

So, the direct response isn't good. Instead, black should answer indirectly, as we just saw.

That's the best way to punish today's trick play.

Trick plays.

BANG!

Look at the left side. This position is common in even games too.

When black opens with sanrensei, you'll often see this position.

Actually, trick plays from six stone games also often appear in even games.

Many weaker players are annoyed by this invasion.

You may wish that white would invade on the third line like this instead.

Even if you're not sure about the continuation, you can just attach here and it's kind of easy.

But, if white invades here, it's not so easy for black to answer.

Some players even want to put their handicap stones on the third line or one space closer like this.

They want to put the six stones wherever they wish to.

Black doesn't want to reinforce here though.

If white is a very strong player, like a pro, most amateur players answer like this with black.

White would hane, and many players cut here and make it worse.

But, black normally pulls back here and white connects.

Defending the corner should be right now, but black doesn't normally play here.

Some players move out with this stone, and that's a bad idea.

Black jumps into the center, but white enters the corner, and black can't get a good result.

Many players play like this as black, and ruin the game in the opening.

Players around 5~7k usually attach on top.

This is my dad's favorite move.

He's been playing Go for 45 years, but he still likes to play like this.

He even plays this move when I play a game with him.

White hanes and black cuts. White ataris here, and black doesn't extend, but counter-ataris.

And white makes a ponnuki, and black answers. Many players seem to think that this ponnuki is only worth two points.

You can't win the game if you let white capture your stone like this.

Even if it's a six stone handicap game.

White's ponnuki shape is very good, especially in the opening.

Black shouldn't play like this, except in very specific situations.

If black's already limited white's influence, black can play like this, but usually it's no good.

Next, white can peep here and increase white's center influence. Black shouldn't play like this.

Attaching on top is better than attaching underneath.

But, they're both similar and both bad.

In this case, black should play a diagonal move.

Black shouldn't try too hard to capture white. That'll never be successful.

This diagonal move is right.

This is a subtle attack. If white weakly plays here to come out,

Don't worry about anything, just push from behind.

White's extension is the only answer, and black wedges on the left side.

If white connects, hane under, and if white wedges here, just answer.

If white cuts, just extend like this.

Even if white takes black's single stone, it's not worth 30 points this time.

This is different to the last variation.

White spent so many moves to capture one stone.

If the last ponnuki was gold, this one is less valuable than gold dust.

This is terrible for white, so white would never play like this.

Therefore, white wouldn't even think about this diagonal move.

White would push here and it's an important moment for black.

Black should hane, and if white hanes too, cut here.

There are no other options for white now, only this jump.

Then, block on the outside. Black must jump here.

If white peeps, connect to reinforce the weakness.

And then just answer whatever moves white wants to play here.

White can live on the left side, but

Black ataris here, and the result is very good for black.

Even if white lives on the inside, it's too bad. Because black's outside position is so powerful.

This is the best result for black, to seal white in.

White won't play like this again, because black's responses are very good.

How can white win the game by making small life on the inside?

White would move out like this, to separate black.

Trying to enclose white like this is clumsy. These sorts of moves don't normally work in Go.

You can think about a leaning strategy in this case.

Black's aiming to attack the three stones, but black pressures white over here first.

If white hanes, extend. Cutting and blocking are miai for black.

If white pushes up here, don't worry about the left side anymore.

The lower side is bigger.

If white cuts next, don't worry, just capture the corner stone.

You should know that the corner is far bigger than the center.

Since white's shape is so bad, white can't get a good result.

Black can attack both sides with this attachment, and gain some benefits.

So, in this case, this diagonal move is good.

This diagonal move is also possible, but let's talk about that move later.

Today you learned about this diagonal move, which is very useful in six stone handicap games.

These attachments are typical bad moves from handicap games.

Don't forget this move against white's higher invasion.

I hope you'll master the variations that occur after this move.

Trick plays.

BANG!

It's time to review a game.

Today's game was played between two 6d players on the Baduk N TV server.

There was a mistake in a popular pattern.

Many players make the same mistakes, so you should learn not to do that.

Let's have a look.

The game looks like a four stone game, but it's an even game.

White played on the side, instead of in the corners.

Black answers with a large knight's move, and white enters the corner.

The problem is this. Why did black hane here, instead of extending?

Blocking isn't right, you should know that you can't get a good result with this hane.

Now black has a floating group in the opening.

Let's find a good move for black.

Entering the corner when black answers with a large knight's move is usual and right.

And black should black here to separate white now.

It's an important moment for black, and black played incorrectly in the game.

We searched a database of 20,000 games from the Baduk N TV server.

And let's also consider the psychological aspects behind the moves.

Why does black make this mistake?

Let's see 5d's and 6d's answers here.

A is at 44% and, unexpectedly, the hane under at B is at 34%

There are other moves too, but A to C are the most commonly played moves.

A: 44%, B: 34% and C: 14%, for 5d's and 6d's.

Let's see 7d's and 8d's answers from the Baduk N TV server.

A is about the same, 44%, but B is played more often, 34%.

C and D are at about the same rate - 9.6% each.

It's quite different from 5d's and 6d's answers.

Let's have a look at pros' choice, from a database of 10,000 games.

Most pros play at A. 98.5% of pros choose this move.

B is very unusual, only 1.5%, and no other moves were played.

So, according to this research, A is the right move.

You can consider pros' choices to be right for you.

Let's come back to the game. Black haned here in the game.

Black should have played like this, and this is a joseki.

If you don't know about this joseki, you won't get a good result.

The problem with the hane is this. When white hanes under, black can't block here.

If black blocks, white can cut and hane under to connect.

In addition, black's shape becomes ugly.

We call this 'a bunch of grapes', and it's very bad in go.

You shouldn't make this sort of shape for black.

That's why black couldn't block and connected here.

Black wanted to connect here, but then black needs to reinforce again.

It's gote for black, and the result wasn't good either.

So, black connected here, but the shape of black's stones is still very bad.

The other connection, which I showed you just before, was better than in the game.

Black separated white, but when white blocks here, black was in trouble.

Black doesn't want white to connect under, but he should take care of his own group.

Black descends here, but white peeps in sente.

Oh, I'm sorry, black haned here. This hane was good. It was better than the descent.

However, when white plays here, this black group is a weak group.

If black jumps, white can cap here to attack, and enlarge the left side as well.

Black's trapped inside white's influence.

Let's go back and look at that sequence again.

When white invades at 3-3, if you're not confident enough, you can think about blocking here,

But, if you avoid fighting, you won't improve.

So, blocking here was good in that way.

Black must extend here, and if white pushes, then answer like this.

White would continue like this, and you'd best learn about this pattern.

White would jump here next, and this attachment is very important.

If you don't know about it, and play somewhere like this,

White can peep here and jump to connect his stone.

White's center influence is active and lively, while black's struggling on the second line.

Try to remember the right moves.

Don't hane here in this case.

This hane under is tolerable, or extending here is still better than in the game.

If you hane, white's hane under is good, and black doesn't have a good move now.

You should think about your opponent's response before playing a move.

It looks like black didn't even read one move ahead here.

Today we looked at trick plays in six stone handicap games.

Remember that these trick plays can also appear in even games with the sanrensei.

Also, don't forget how to respond to white's 3-3 invasion when you play a large knight's move.

There won't be any problems if you take some time to read before playing.

Trick plays.

BANG!

Thank you!
