Hello everyone, welcome to 'Becoming 5 Kyu', I'm Shim Wooseop 7d.

In Go, life and death is troublesome, but you can't avoid it.

If you want to improve at this skill, you have to find a good way of doing so.

You may try to solving difficult problems.

Or, solving lots of easy problems is another way.

As a kyu player, you have to develop your interest and curiosity about Go to improve.

Start with easy tsumego problems. If you can't solve them, check the answer.

But you need to note problems you couldn't solve, so you can review them later.

If you learn many patterns, your reading skills will improve.

Let's start today's lesson.

We're going to start off with a fuseki.

If you understand the relationships between stones, you can invade more easily.

Become familiar with the sanrensei.

There aren't many josekis in this formation.

Therefore, you can manage your opening more easily.

Anyone can play this joseki.

To prevent a double wing, white has to approach in the lower right.

If you want a big moyo, this pincer is conceivable.

However, it's hard to maintain the moyo until the end.

This jump is good, and helps us to learn about invasions near the corner.

If white extends, this approach is necessary.

And here's another simple joseki.

To finish the joseki, white needs to play a knight's move.

White got a good moyo at the bottom.

Previously, we learned about black's invasion here.

Today we'll learn more about the invasion on the right side.

This third line invasion is more common.

This one is mainly played in handicap games.

We started looking at this move last time.

I said that black's next move is the most important one.

An attachment can't be good in this situation.

These two kosumis are the best responses.

Let's learn a bit more about black's attack on white.

In this case, this kosumi is proper.

When there's a white stone here, the other kosumi is correct.

It strengthens black, while separating white.

Since there's no stone there now, black should play here.

If white tries to escape, black should block white with this hane.

If white plays an empty triangle, black shouldn't attack directly.

Instead, this attachment is a good move [leaning attack].

After that, one of white's two groups will suffer a lot.

At this point, white can persevere like this.

This hane is the most complicated response.

If you understand this variation, there's nothing to worry about.

When black cuts, this jump is plausible.

This move aims at both these jumps at the same time.

Since black has invested a lot at top, he has to block here.

Then white has to peep.

After that, connecting here is a normal move.

After the atari, white has to connect.

Even though black blocks, white can make two eyes.

This group is nearly alive.

Black has a cutting point and the bottom group isn't stable yet.

Even though the ladder's unfavorable, black can hang tough with the extension.

There's a weak point in black's group.

These moves are unpleasant for black. He has only one eye.

You may be afraid of white moving out.

This aji seems to be a burden for black.

This move looks scary in handicap games.

But if you remember this attachment, you don't have to worry about it.

If white hanes, this counter-hane is a wonderful move!

Black can cut here or hane. It's miai.

If white extends, it's a good opportunity for black.

This hane is good, and next, push here.

Remember that white's cutting stones can't be captured.

But, because of this cutting point, white can't block.

So black can drive right through white's shape.


White's in trouble.

Therefore, black's group is safe.

Black has good aji.

If white tenukis, black can attack this group later.

This is a vital point.

Inevitably, white has to answer here.

Then this wedge is a great combination!

If white ataris, black atari too.

If white captures this stone, black will pinch.

It's a false eye, so the entire group is dead.

If white connects here, black captures these three stones.

At the same time, these two stones are in atari.

By capturing these pivotal stones, black's groups are connected.

This is black's aim.

This peep is a bad exchange.

Because it lets black build an iron wall here.

Even though white's group is alive, black's still successful.

Let's go back to the previous variation.

Black will be fine with simple answers.

But, when white peeps, black might have other choices.

How about this push?

If white plays here, black can connect, leaving more aji.

White's eye space is narrower than in the previous variation.

If white pushes, black will hane.

Locally this move is good, but the extension is painful for white.

White will get damaged.

If white hanes, this wedge is a good move.

Because of the double atari, white can't capture this stone.

When black connects, these stones die.

This cutting stone becomes useless.

This is a good tesuji to connect white's other groups.

But black will atari here.

In doing so, he can fortify his moyo.

Even though white got some points, the corner was already open before.

And black became very solid. It's a failure for white.

Aren't there any good answers for white?

We'll learn about that next time...

Let's move on to the practical tsumego problems.

It's another episode about life and death problems in the corner.

This sort of position occurs frequently in Go.

We've learned about the 3-3 invasion many times.

This invasion is focused more on the side.

If black connects, white can push here. We looked at that last time.

When black's solid on the right side, white can push like this.

In response, black should block on the wider side.

This jump looks like the proper move.

But white will be in trouble after black attaches here.

After this tiger's mouth, white must save the corner.

Then the top side will get badly damaged.

Because of that, this knight's move is good.

If black cuts, white pinches here.

After that forcing move, he can easily live in the corner.

It's bad for black.

If black plays here, white hanes.

After this move, white can push here in sente.

Black has to defend his cutting point.

After those exchanges, white can make two eyes.

Thanks to many forcing moves, this group lives easily.

This atari was sente.

In some cases, it may not be sente.

Some might think white can still live with the hane.

But it's a big mistake. Sure, if black hanes, this group lives.

But this is the vital point.

Because black can connect this hane, white's group dies.

When you have a small eye space, you need to play carefully.

Playing a tiger's mouth is the answer.

Unlike the previous variation, black can't connect.

Even if black hanes, white can easily live.

You should compare the difference between the two variations.

However, there's another wrong way to live here.

This move at 3-3 looks more stable and better.

If black kosumis, it'll be the same as the other variation we looked at.

If black hanes, white can't block here.

Since black's already protected this weakness, white's move isn't sente anymore.

This group will die after the hane.

Therefore, white has to defend here.

Unfortunately, this peep isn't sente.

This is the vital point, so white can't live.

White needs to play here.

After that, black can destroy the top side.

Even though white lived in the corner, it's no good.

White can push towards the corner.

Then, if you remember this knight's move, there will be no problem.

How about this double hane?

The extension lets white live so easily.

When black double hanes, white doesn't need to be greedy.

He has to atari here.

But this move is too greedy.

White even can't live by capturing black's stones.

In this case, this atari is good enough.

Remember that there's another way to live in black's corner, other than playing at 3-3.

You should try it in your games!

Thank you!
