Hello everyone,

this time we will discuss a Go Seigen game played and Fujisawa Kuranosuke,

later known as Fujisawa Hosai. The game was played in March 1953

Go Seigen wore black stones.

This joseki going to play here, rarely seen today.

White takes territory, and black influence

In the upper corner they will make a joseki that it is more common today

At this point in the game it could almost say it is a little better

black, since White is lost in this side of the board and

Black occupy the rest with influence.

Black stretch

It could have been here but it is open,

This is the point

white kakari

The usual answer is this,

white extends

It could not be keima that since it would give the opportunity to black press in this way

combining well with these three stones, therefore this is the best move for white

Black runs.

Another possibility was there, but it leaves an invasion easy target in this way.

The possibility of playing in the focus had

disadvantage that leaves easy for white invasion in san-san

since either side by black block which makes inefficient

or this or this stone, if blocked by Here, this stone

It is inefficient, however if this stone It was there, which is where he has played,

San-san is easy answers because this is the wider side

This is perhaps the reason why Go Seigen chooses that point

White extends here. This is a very big move, delimits a lot of territory and increases

pressure on these three black stones. White is perhaps waiting for this movement

that would be met with keima, being favorable position white

This is unacceptable for Go Seigen, and thus jumps.

This point or this area is desirable for both players, if turn white, or something like that

delimit a great Moyo, and playing Moyo is black on this side

As you can see here there is no white stone

It's time to go, do it this way white

black extends

white here

If black would respond in this way, this gives good shape to white,

So black plays below,

Extira

keima

This move prevents grow the black moyo

and reinforces or strengthens the group White

In this play, it usually responds well, but now ... now ... this move by black

It is logical since the situation is more balanced, but

both players are playing tenuki, and in this case white will not play that way

but it increases the pressure on these three stones,

If black jumps,

Now, White could play nobi, and this situation is more favorable for white

since the black has a black floating group, no base is

well established in this side

In this move, black responds again tenuki

playing well and white near the three black stones above

this move,

besides ensuring corner it is looking at these stones, leaves the future

something like this,

this wall is weak

Now, this play, this and this, are miai. White is expected this.

Black White takes territory but change takes strength and influence in the center

It was what White expected, however, Go Seigen will make a move

perhaps unexpected, he plays ogeima; this play in a way to mark the strategy

all the rest of the game

Now if Black plays tenuki

Because of this white court could very easy to live this way.

Black has to defend, and this extension leaves this group based

enough to live, therefore, black

play thus preventing this target group stated

extends

this blockade

while maintaining the pressure on this target group, says the corner

Keima to escape

This continuous play with the idea of ​​this, to keep the division

between these two groups that will go Go Seigen attacking alternately during the game

Hane

stretches

Kosumi, to connect

Now Go Seigen played here

Go Seigen said at the end of the game that this movement is a little slow

Perhaps it would have been better thing

You are using these stones be cut ... prevent connect ... and something

The weakness of this group is, but Go Seigen played solid here. It is a movement that

well reinforces these stones

After this move sequence above no longer makes sense because

this stone

These two stones are quite inefficient and also this exchange

favors the target group, therefore this sequence is no longer interesting

Black will play keima. No court has problems because if you try white

It is this weakness

this cut is quite strong, so So you can not cut, white defends

Black keima again, keima, is looking for a connection there or go here

and make room

This move is to refozar a little this group, and sente because if White does not answer,

this sequence is inadmissible for white, after playing here ...

This is unacceptable for so white both must answer here.

black here

Now it would have been the easy move for White to play here, stabilizing this group as

It is practically alive, however White note the weakness of these

three stones and see that they can cut, and what they do, because if black plays

thus cutting leave a good and comfortable position for white and

these four stones are now quite weak, therefore, can not black

play there. Go Seigen played here, and after this movement seems white

the result is quite favorable for white has achieved this column

Central, enough strength, these three stones remain weak and

not expected to be any problem, however, after this move

normally

crashes, in most cases be blocked in this way, however

Go Seigen here had expected This cut is quite strong

... because we can interleave this sequence ...

Now appears weak white

That is the point at which security white group is in question,

It is quite uncomfortable, therefore no It can be locked at this time

White plays first here, if black Hane, now can be locked, since

cutting is different

not weakness appears,

therefore, black does not respond here but stretching

and we see the enormous power they have achieved black in the center

white Hane

and now the black initiate a strong attack on the white group,

that way

White connects, here would have been more I Hane easy to play, because if black blocks

These two stones are hunted, so both the target group lives

However, playing first connection,

White can not defend, you must leave, bamboo knot, looking for the connection ...

And here

Black here, and this move is sente since after playing here in this area there are court

the group still has no eyes, Here are cut, danger, therefore

white add one more stone for the connection is solid

and now black plays in this way, stabilizing the entire center and

stones that are weak have left to become pregnant and concern for

White longer this group and now the above

Play here. Now let's see a subtlety of Go Seigen

Would cut here ...

For this group is reduced to the minimum

expression and may not be able to live, but the court does not work, as we shall see

white kosumi

and has binding

Then, the cut in this way does not work

Before playing this, Go Seigen comes here once again making use of these

three stones, because if white plays well Now the sequence we've seen

it works,

... and there is no connection

White is cut and has difficulty

live there

Thus

this play

White can not answer here but here

making use of dead stones

atari

atari

This move is tesuji, because if black comes here, is is this cut

that if he defends, is perfectly connected,

and if it comes up, atari ..., no connection, no problem,

and white is threatening to play here and capture five stones; If black defends

for white connection it is very simple, no It has problem

At this time, Go Seigen

Play here

abandons these five stones, on the other hand is almost

best choice for white

here you will not play because black short all,

Nor did it this, since

come here, first atari, is there, and atari, no escape

It is almost forced to come to eat these stones, and now connects black

thus keeping this divided group, keeping the pressure on that group,

in exchange for having delivered these five stones, and even having left

This point is very large in favor of white and also this move is sente.

The game'd rather good for white as long as this

group to achieve live; it is the turn of white and play here

White is waiting for a response so black as to defend the

territory and easily live without But Go Seigen

perhaps he had anticipated this and had prepared the answer, here

this movement, tesuji, hard to see

is that the target group can not make eyes

let's see some sequences, example, if there is ...

Although black loses these two stones, leaves no eye, the white group is dead

and if he comes here ...

... and this move kills the target group

since this and this are miai.

The white group is dead

In this position white they decide to leave the group and try to compensate for that

loss winning the corner, play here

Go Seigen currently plays here and it is questionable if he could have played

here to save the corner, since white group could never escape

White here.

This is very painful for black. Star losing stone

but they manage to live in the corner in small,

and white now take perhaps the biggest point

currently on the board that is here.

Black must now live, playing there, but

first try to make this kikahsi, which is a mistake because Fujisawa see this tesuji

since black can not cut

They appear these two weaknesses, and the target group resurrects

Play black

This exchange is bad for Black, now must live

Not worth the cut because he plays there, you have to play here first

connect

And at this time the game is White favorable since they have one quarter

board, practically, this side, this corner, and change only black

They have this corner and this group. With a movement like this, ensuring that

lateral possibly white winning the game, but there was another movement

very big this further erodes the possible territory

black, and also prevents a possible invasion of this type, and choose Fujisawa

this movement, and this gives the last chance

a Go Seigen to win the game, again taking advantage of these three

stones that were lost at the beginning.

and now White can not play this way

that follow a sequence such

and he connected, and also the white group is still alive, which would now heading

favorable to Black

Thus, white can not play here, you have to play below

must cut

Kosumi. This move is possibly Ultimately, because after bamboo knot

threatens to cut the group and have two cutoffs to save these stones

White connects here that is threatening to go in there and get that group,

but black makes bamboo knot,

It is threatening to cut here and now white decides

save this group is larger,

short black,

white connects

And with this move, White is forced to cut here to save this group,

and connecting black is final,

these parts are dead, saved these stones, these are now muertasy

and these three are recovered, since white can not leave here, 1, 2, 1, 2, 3 ...

and even if you connect ..., 1, 2, 1, 2, 3 ...

That is, the game has overturned awesome here,

White has been dead, black has these stones recovered, he saved

these, has captured these ... and although the game continued some more movements,

White abandoned. We have seen with what skill Go Seigen

He has pressed on attacking white alternatively the two white groups

playing with the influence of their stones.

A historic and masterful game
