『Do you know the standard moves? 3-3point joseki』

Hello everyone.

Thank you for picking up this book.
This is my 10th published book.It is also the first book I have published in English.

The author is Tarou Usami.
I am a Go teacher in Tokyo, Japan（I worked at the Japan GO Association）.

Now I teach Go to children, give online lessons, and give Go instruction sessions.

I created this book with the intention of telling students who teach Go that they can understand the 3-3point（Sansan） Joseki with just this one book, and that if they read this they'll be fine.

3-3point（Sansan） Joseki appears frequently in Go games.

In this book, I have explained as many 3-3point（Sansan） Joseki as possible.There are some difficult moves.You don't need to remember everything.Please feel free to read it.I hope you learn at least one new thing from this book.

Tarou Usami

『Do you know the standard moves? 3-3point joseki』

This book explains the three basic moves of 3-3point（Sansan） Joseki.

I'll explain the basics as simply as possible.

【Three patterns of 3-3point（Sansan） Joseki】

They are classified into the following three types.

①【Direct 3-3point（Sansan） Joseki】

②【The 3-3point（Sansan） Joseki after Hasami(Pincer)】

③【The 3-3point（Sansan） Joseki after Shimari(corner enclosure)】

There are other Sansan Joseki moves, but this time I will explain these three basic moves.

Each of these will be explained in Chapters 1 to 3.

Chapter 1【Direct 3-3point（Sansan） Joseki】

The white1 in the upper right corner is in the 3-3point（Sansan）.

In Japanese it is "sansan."

It's the third one, whether you count from the top or from the right.
There are places on all four corners.

【The first thing to remember】

When your opponent plays the Sansan Joseki move, respond appropriately.

You must play "Osae".

【You need to think about the direction of the "Osae".】

example.　You play black.

Do you want to play A or B?

The correct answer is A.

Because there is a black stone △ on the right side.

If you want to cherish the right side, you "Osae" the right side.

【supplementary explanation】

Recently, with the advent of AI, the way we think about Go has changed somewhat.

There are cases where you can play "Osae" on the other hand, but generally it is best to play "Osae" on A.

【The ancient 3-3point（Sansan） Joseki】

The diagram above shows the basic shape.

This is one of the first moves you learn when you start playing Go.
This has now become a nostalgic form.

In the past, it was said that black had the best chance in this situation.Therefore, the white player did not immediately create this formation.

However, with the development of AI, changes have come to the world of Go.

Introducing a new 3-3point（Sansan） Joseki.
It is Direct 3-3point（Sansan） Joseki.

This formula will be explained in more detail later.

【First, let's study some old joseki.】

Nowadays, it is rare to see the standard move of playing black-4.
（9 to 12　"hanetsugi" can no longer be played.）

【Because White plays 7 and 9】

This is the standard nowadays.

This gives the white player the first move (Sente).
The "Sente" is important.

And the black stone is weaker than you might think.

【The White player's aim is to play at peep（nozoki) later】

This is a development that White prefers.

So, I began to think that I didn't want to play in this position as black.

【If this happens, black has the advantage.】

The ancient 3-3point（Sansan） Joseki.

In this situation, the black player has a greater advantage than you might think.

The strength of the stone changes depending on whether or not you use a "hanetsugi".

【When using "Hanetsugi"】

Doesn't the black stone look strong?

【Even if you get hit by A, you can bounce back with B】

In fact, the white player probably wouldn't want to play A.

Therefore, the white player will not play "hanetsugi".

【And the Black A move was no longer immediately available.】

One thing to note here.

If this situation occurs, the White player should make a firm move to White 9.

If you don't do this, things can get pretty bad.

【If Black plays 10...】

The white stone may die.

【It'll be fine if you use "Hanetsugi"...】

However, "Hanetsugi" makes the black stone stronger.

This may be unavoidable.

【If you forget to use "Hanetsugi"...】

This will kill the white stone.

Don't be lazy with White 11.

Black 18 is the critical point of the shape.

Let's also consider the resistance of White.

As white, I would like to play white 19.
Black will play 22 and die.

Be careful not to end up with something like this.

【I'll add it just to be sure】

If White plays 23, play Black 24!

Black 24 should not be played as an "Osae".　It might end up being "Kou (ko)".If you play calmly you'll be fine.

Black's 16th position is a "false eye（kakeme)".
White cannot make two eyes.

【The only remaining piece is the black 4 "hane"】

Before explaining the Direct 3-3point（Sansan） Joseki, let's look at the only remaining Joseki move, which is to play Black 4.

If you are playing black and want to secure a corner, you should play like this.

Black 4 and Black 6 "double Hane (nidan bane)(nidan hane)"

To repeat, this is a standard move when you want to secure a corner.

For example, choose this joseki when there are white stones on the outside.

【White's Response】

In this form, white is bad.
I don't want to play white 7.

Because the white stones get trapped in the corners.

Both the left and right pieces will belong to black.
This is a shape that black is happy with.

【Why White 7 is bad】

If the white player slacks off, he dies.
White will be in trouble if Black plays "sagari" at 1.

No matter how white people are perceived, life is hard.

【An example of a Go puzzle (tumego)】

Being hit in this way, the white stone dies.
Black 7 is a "nakate (nakade)."

This shape requires caution.

【So with White 7 I will play "cut".】

This is the standard move.
The cut of White 7 is important.

Black secures the corners, and white cares for the outside.

This is the opposite of the standard move up until now where White secures the corner.

Again, Black 4 and Black 6 are standard moves to secure a corner.

The standard move of playing Black 4 and "Hane" has now reached this point.

So, in the end, what should Black do when White plays Direct 3-3point（Sansan） Joseki?

From here, I will explain the Direct 3-3point（Sansan） Joseki, which was created with the advent of AI.

【The Direct 3-3point（Sansan） Joseki】

I will write some difficult parts, but I will teach you some simple rules at the end. Enjoy playing Go using these standard moves.

【The basic form of Direct 3-3point（Sansan） Joseki】

The Black 4 "Nobi" is important.　Black 4 is played with a "nobi" piece rather than a "hane" piece. This is the basic shape.

Strictly speaking, Black 4 could also play "Keima (knight's move)".

However, doing so would make things more difficult, so it's okay to play Black 4 as a "Nobi".

This opening move goes up to White 5.

The black player now takes the initiative and moves to a larger area.

Black has the first move (sente).
This idea of ​​taking the "sente" is important in modern Go.

【I will explain using a 19x19 board.】

There is no need to play A after playing Direct 3-3point（Sansan） Joseki.

Let's play quickly, such as black 11.
This feeling is important.

I think in the past, many people would have typed A.

Of course, playing A is not a bad move.
However, it is becoming less common to see them these days.

I think the corners are more important than the side.

I would also like to point out that the black stone in the upper right corner is not as weak as you might think.

Without reaching for the black stone in the upper right corner, you move ahead to the larger area.

【It's okay if white comes closer.】

As I said before, the black stone is not as weak as you might think.

Playing Black 2 is a wait and see strategy.

If White plays 3, it is okay to play Black 4.

【White 3 and Nobi】

Black 4 and Black 6 "Hanekaketsugi" will be fine.
This is the shape of "Sabaki（settling a group）".

This "Hanekaketsugi" is a technique that I would like you to remember.
It appears often in modern Go.

【Progress after "Hanekaketsugi"】

If A is played, it is possible to change to "Kou".
If White has no moves, B is a great move.
Black could also play at C.

If you know this technique, you will be able to play Go with a sense of speed.

However, when playing "Oki-Go（handicap game）", it is okay to take one firm move.

【Black 4's "Nobi" is the recommended move.】

This is the easiest way.　The end comes with White 5's "Keima (knight's move)".

Here we will also explain some slightly more difficult movements.

At the end, we also explain a simple form, so please use it if you find it difficult.

【Standard move when playing White 5】

In this case, there is a lot to remember.

Basically, the standard move ends when the white piece reaches 7.

Black reserves this shape.Then, depending on how the upcoming games go, we'll decide what to do.

This is a bit of a difficult concept.

Black is looking forward to playing A or B next.

It doesn't play right away.

The black player will take the "sente" here.

This is the modern Go strategy demonstrated by AI.

【If you play black 8, it's a "gote"】

Black 8 is a normal move, but up to Black 10 it's a "gote."

Modern Go places a lot of emphasis on the "sente" move, so I don't want to play like this.

As shown in the figure below,

If you have black△ stone, "Nobi" is a good move.

This idea of ​​reservation is an important concept in understanding Direct 3-3point（Sansan） Joseki.

When you want to secure the right side, remember that it's called "Nobi" with the black 8.

【If you want to remove the top part...】

Black plays a "hane" into the corner.

This will allow you to make the upper area black.

This is a standard move with a long sequence of steps.

※White 15 is in the position of Black 8.

This joseki is a little difficult, so try studying it once you get used to it.
This is a standard move for advanced players.

【The simplest move in Direct 3-3point（Sansan） Joseki】

This is the conclusion of Chapter 1.
If you found the explanation so far difficult, try playing Go like this.

【Let's keep playing it with "Nobi"!】

This movement is fine.

Let's just remember this.

In some situations, it might put you at a slight disadvantage, but it's not a big deal.Such developments are possible.

This joseki is fine for beginners. Once you get used to it, try using different joseki.

This concludes Chapter 1.【Direct 3-3point（Sansan） Joseki】
